Wie die Analyse auf helminth Eier zu über

The present invention relates to a method for determining the biological activity of helminth eggs, namely of Trichuris eggs, preferably Trichuris suis eggs, in various stages of their life cycle. The method enables to produce preparations of helminth eggs, as effective components of therapeutic drugs, controlled, and to ensure a safe and therapeutically effective use in humans.

Eine solche Aktivierung beeinflusst auch das Auftreten und den Verlauf von Autoimmunkrankheiten. Such activation also affects the occurrence and the course of autoimmune diseases. Epidemiological studies show that in regions with high rates of worm infections autoimmune diseases are less common than in regions in which these infection rates are lower due to better hygienic conditions. According to recent studies of people with Trichuris suis infection seems to be only transient and the worms are obviously repelled before they can reproduce.

Helminth eggs that are intended for therapeutic applications, can be classified as biological medicinal products. A key parameter that needs to be tested during manufacture and application of biological medicines, the biological activity, which is ultimately a measure of the therapeutic effectiveness of the drug. Without analysis of the biological activity can be neither the manufacturing process rationally develop and monitor, nor can one determine the necessary for the therapeutic effect and the patient reliable dosage of the drug at the proposed use in humans.

For this reason, only those helminth egg preparations can safely and effectively be used as drugs, their biological activity is sufficiently serious. Die Bestimmung der Embryonierungsrate Kringel et al. Previously available for Trichuris suis three analytical methods are available, but only inadequately characterize the biological activity.

The investigation is carried out microscopically. From the morphological evaluation alone can however, in contrast to the molecular biological method presented in this application not be inferred with certainty that the larvae are actually completely embryoniert.

In addition, the morphological assessment of the experience of the observer and the subjective classification of morphological borderline cases requires limited the accuracy and precision of this method. Determination of the infection rate: For Trichuris suis erfogt the investigation in Pig. Zu einem bestimmten Zeitpunkt nach Infektion wird die Anzahl der in der Darmschleimhaut etablierten Larven bestimmt und in Relation zur applizierten Dosis an TSO gesetzt Kringel et al. The problem with determining the rate of infection, that they are not solely dependent on the functionality of the helminth eggs, but equally of individual host factors, such as the immune system, the intestinal flora and intestinal function of animals.

The determination of the rate of infection in the test animals is thus linked intrinsically with high variability and can not be standardized because of the natural test system, which greatly restricts the suitability as a biological activity test. Weiterhin beschreibt Kringel et al. Further wie die Analyse auf helminth Eier zu über kringle et al. There is no direct quantitative relationship, from which could be close to the number of eggs in the feces on the rate of infection or the biological activity of adult larvae.

Die Methode von Kringel et al. The method of kringle et al. However, the methods described are not sufficient to determine the biological activity of helminth egg preparations with the required accuracy for medical products.

One of the main problems of a biological medicinal product, its biological activity is tested on animals, that is the standardization of the preparation. The use of wie die Analyse auf helminth Eier zu über models, such as the above-mentioned infection of pigs is extremely complicated and takes a considerable time to complete.

In the present invention, a method is described, be carried out in which various types of tests relating to different aspects of the development of the helminth eggs and their biological activity. In order to arrive at a reliable statement, one of the tests according to the invention Wie wird man von pinworms oder Würmern zu befreien be carried out in to be examined batch least, but preferably at least three, more preferably at least four or even five of the tests described herein are performed, the relevant parameters are determined.

The results of each test are considered as a whole, a suitable helminth preparation has to meet the specified wie die Analyse auf helminth Eier zu über in each test, so that from visit web page the conclusion can be drawn that the helminth egg preparation is suitable for pharmaceutical use. There is thus a great need for an industrially applicable process which comprehensively and reliably analyze the biological activity of TSO and other helminth eggs in various stages wie die Analyse auf helminth Eier zu über development and it characterizes different biological functions of helminth eggs.

It is an object of the present invention to analyze comprehensively through in more detail below process carried out wie die Analyse auf helminth Eier zu über biological activity of helminth eggs and so to allow one hand, a tight control of the production process, on the other hand a safe and therapeutically effective application in patients. From complex problem and the shortcomings of previously known methods it is clear that a reliable determination of biological activity usually can not be achieved by a single process step.

Therefore, a system has been developed consisting of five rules that examine each different biological roles of helminths at a certain stage of their life cycle.

Optionally, it can be used for the characterization of certain aspects of the biological activity, or sufficient for the monitoring of partial stages of manufacture to carry out only individual steps of the method.

The five individual steps rely on test principles that have already been described in another context. Die Adaption auf embryonierte Helminth-Eier, insbesondere embryonierte Eier von Trichuris suis, ist neu und bedurfte der Entwicklung einer Reihe von neuen bisher noch nicht beschriebenen Teilschritten.

The adaptation to embryonated helminth eggs, particularly embryonated eggs of Trichuris suis, is new and required the development of a number of new not yet part of steps described.

Also especially eggs of Trichuris is the entire procedure that tests five different aspects of biological activity and thus enables a comprehensive characterization, novel and for helminth eggs, suis, has not been previously described.

Preferred common feature of three of visit web page five methods described is the activation of dormant Trichuris larvae by pre-incubation at elevated temperature.

Another feature of this method is that it can be performed with intact, viablen helminth eggs and that the parameters measured only by the activity of helminth eggs and not by host factors wie die Analyse auf helminth Eier zu über the specific capabilities of the test person performing depend click at this page, therefore are therefore more objective than the methods previously used.

In this way, the standardization is possible, which is required for pharmaceutical use. By the method, it is possible to determine the biological activity of helminth egg preparations reliably with the required accuracy for a pharmaceutical product. The exact determination of the biological activity of helminth ova, as described in this invention, is an essential step in the manufacture of a pharmaceutical product applicable.

With each cell division during embryonic development of the set of chromosomes is duplicated and distributed to the two daughter cells. Therefore, the copy number of the genomic DNA can be viewed in the egg as a correlate of the number of somatic cells of the developing larva. Die Bestimmung der Kopienzahl genomischer DNA kann also genutzt werden, um in einem beliebigen Stadium den Status der Embryonalentwicklung der sich entwickelnden Larven abzubilden.

The determination of the copy number of genomic DNA can thus be used to map the status of the embryonic development of the developing larvae at any stage.

Die Embryonierung ist Teil des pharmazeutischen Herstellungsprozesses der Helminth-Eier. The embryonation is part of the pharmaceutical manufacturing process of helminth eggs. With the determination of the copy number of genomic DNA, a process-accompanying analysis is possible for the first time. It allows for a rational development of the manufacturing process and to study the influence of process changes and other routine monitoring of production during Embryonierungsphase.

Using quantitative PCR technology can be a determination of the copy number of a particular nucleic acid sequence are carried out in a sample. The more copies are present in a given nucleic acid sequence in the sample, the faster the Amplifikationsplateau is achieved. Durch Eichkurven kann die Anzahl der Kopien relativ genau bestimmt werden. By calibration curves the number of copies can be determined relatively accurately.

One of the methods commonly used here is Real Time PCR or the so-called TaqMan PCR. Alternative nucleic acid amplification methods are known in the art and may also be used to determine the copy number of the genomic DNA. Die genauen Kopienzahlen werden in der Regel mit geeigneten Eichkurven ermittelt. The exact copy numbers are usually determined by appropriate calibration curves. However, this test has a different purpose, namely the testing of methods for inactivating helminths.

For the skilled person it wie die Analyse auf helminth Eier zu über obvious that also other parts can be used from the genome of Trichuris suis for the determination of the copy number. A precondition for the this web page of the sequence, that this is a nucleotide sequence that specifically suis occurs in Trichuris and that there are no similar sequences in other organisms that could possibly reach as contamination in the investigated sample.

Die Bestimmung der Kopienzahl der genomischen DNA hat auch einen Nebeneffekt. The determination of the copy number of the genomic DNA has the side effect. It can be confirmed that the desired organism is present in the preparation and use of suitable other sequences may also be the detection made whether contamination with other organisms present. An important aspect that should not be overlooked in determining the copy number of genomic DNA is that helminth eggs have to be digested before the measurement.

Cell кивнул, von Würmern dekaris Bewertungen свою is always carried out when the cell components must be available in an accessible form for each inspection step.

Many methods for determining the viability of cells based on the examination of the metabolic activity. As energy carriers and memory adenosine triphosphate plays a central wie die Analyse auf helminth Eier zu über in cellular metabolism and can therefore be used as markers to determine the intracellular metabolic activity. The von Parasiten Volksmittel Wie wird man befreien of adenosine triphosphate in biological systems, is made possible by the measurement of luminescence with the aid of the luciferase reaction.

Das eukaryontische Enzym katalysiert die Oxidation von Luciferin in Anwesenheit von Adenosintriphosphat, Sauerstoff und Magnesiumionen unter Lichtaussendung zu Oxyluciferin. The luminescence is defined as the emission "cold" light. Luminescence systems are based on the chemical, biochemical or electrochemical activation of substrates to leave a part of the excitation energy in the form of light when returning to the ground state.

Determination of ATP content to study the metabolic activity of helminth egg populations is inventively preferred. To study the metabolic activity of individual helminth eggs, and staining are suitable with tetrazolium, which were originally developed wie die Analyse auf helminth Eier zu über freely accessible animal cells in cell cultures or histological sections.

Die Tetrazoliumverbindungen werden in metabolisch aktiven Zellen durch die Wirkung mitochondrialer Enzyme zu farbigen Formazanen reduziert, die sich in den Zellen ablagern. The tetrazolium compounds are reduced in metabolically active cells by the action of mitochondrial enzymes to colored formazanes that deposit in the cells. In order to determine the metabolic activity, has a "zero" value can be determined.

Here is a comparison value is determined by the metabolic activity of the respective. In a preferred embodiment of the "zero value" with inactive helminth eggs is determined. Das Adenosintriphosphat-Signal von auf diese Weise inaktivierten Proben konnte nahezu auf Hintergrundrauschen reduziert werden. The adenosine triphosphate signal from inactivated in this way samples could be reduced to almost background noise.

The preparation kryoinaktivierter egg samples is carried out in phosphate-buffered physiological saline. The cryoinactivation can of course be used in the other method of determination.

By cryoinactivation specifically the effect of pre-incubation can be measured. For inactivated killed helminth eggs, no increase of adenosine triphosphate is recognizable even after preincubation.

As this method leads to a complete disruption of the eggs and thus to a quantitative release of wie die Analyse auf helminth Eier zu über nucleotide. A typical ATP calibration curve is shown in FIG. Eine relevante Wechselwirkung der komplexen Matrix des Ei-Homogenats mit der Luciferasereaktion und der Lumineszenz ist damit nicht zu erkennen.

A significant interaction of the complex matrix of egg homogenate with the luciferase reaction and the luminescence is thus not visible. Das Beispiel zeigt eindeutig, dass die Lumineszenzmessung eingesetzt werden kann, um viable embryonierte Eier von Trichuris suis von inaktivierten und damit nicht viablen Eiern zu differenzieren. The example clearly shows that the luminescence can be used to differentiate suis viable embryonated eggs of Trichuris inactivated and thus not viablen eggs.

However, the successful implementation of the test is only possible with a combination of optimized process parameters consisting of sample activation, sample homogenization and the preparation of appropriate controls by an optimized inactivation. The principle of this method lies in the induction of gene expression, which can only take place in living cells and can be differentiated by means of which between living and dead larvae.

Be particularly advantageous to study the expression of heat shock proteins appear as these can be easily induced by temperature increase and formed messenger RNA mRNA is generally stable against rapid degradation. In a preferred embodiment of the present invention, the gene expression of heat shock protein of T. Inducible gene expression can be done by determining the content of coding for a particular protein inducible messenger RNA.

From the amino acid sequence of the nucleotide sequence of the messenger RNA can be derived. For the expert it is not a problem, determine the appropriate forward and reverse primers and intermediate determine the sequence of a TaqMan probe. Mit Hilfe einer Real Time PCR kann dann die Induktion des Gens bestimmt wie die Analyse auf helminth Eier zu über. Using a real-time PCR can then be determined the induction of the gene.

In addition, it must be a protein that is easily and reliably inducible. One example is the heat shock protein, it can, however, equally well be other inducible by certain stimuli genes are used in the estimation. Der Nachweis der exprimierten Messenger-RNA auf Ebene einzelner Eier gelingt auch durch Fluoreszenz-in situ-Hybridisierung FISH mit einer geeigneten Gen-Sonde.

The detection of expressed messenger RNA at the level of individual eggs is also achieved by fluorescence in situ hybridization FISH with an appropriate gene probe. With particular advantage the egg population can then investigate quickly and reliably using flow cytometry.

The motility of the larva is a condition that they can slip under appropriate environmental conditions. In free-living larvae and worms such as C. In the present invention was surprising and first found suis example of Trichuris that can induce even with not free-living, present in the egg helminth larvae by precise adjustment of the ambient temperature subtle movements.

Hitherto described that the larvae expire on completion of embryonation into an idle state and are activated only after receiving by the appropriate host and hatch. The movements of the larvae in the egg are very slow and only detectable if the eggs are microscopically as in the present invention disclosed in fast motion over a long period.

In combination with image analysis software are used to automate the microscopic motility. In determining the motility of larvae exact temperature for the success of the method is crucial.

After this pre-incubation, the larvae are placed in a suitable microscope, the set temperature can be maintained at least approximately. The principle of this method-step consists of wie die Analyse auf helminth Eier zu über the hatching rate of helminth larvae in the intestine of animals, or alternatively in the intestinal contents, which has been previously removed from experimental animals.

The hatching rate can be determined in one embodiment in the intestinal contents, which is taken from experimental animals, and specifically preferably at the beginning of the colon or the end of the duodenum.

The hatching rate can then be determined in the intestinal contents without the hatching must be directly determined in an experimental animal.

Furthermore, the method can also perform by пойдут wie bei den Eiern von Würmern zu suchen вот the eggs that have passed through the intestines and are recovered from the faeces. This has the advantage that the test animal does not have to wie die Analyse auf helminth Eier zu über killed and can be repeatedly used to determine the hatching.

In the newly developed process step of the intestinal contents is analyzed and counted the eggs intact and abandoned after hatching egg cases in a relatively short distance after inoculation.

The main advantage over that described in the prior art, determination of infectivity is that with hatching only the first phase of the life cycle is investigated, which is influenced by individual host factors only slightly. Surprisingly, it was for Trichuris suis first be shown that the larvae hatch quantitatively not only the appropriate host, the pig, but also in rabbits.

This is, for example Trichuris suis a laboratory animal with smaller intestinal dimensions available, which facilitates the recovery of microscopically small eggs and embryonic membranes significantly. Surprisingly, it was found that the egg shell can be permanently stained with commercial developed for the labeling of proteins fluorescent dyes.

The coupling of fluorescent dyes to the egg-shell greatly facilitates the recovery of the eggs, since the intestinal contents can be examined by fluorescence microscopy. Another important innovation is the use of nichtembryonierten or inactivated helminth eggs as an internal, unchangeable standard.

Diese haben die gleiche Transit- oder Verweilzeit im Darm, bleiben jedoch im Unterschied zu den embryonierten und biologisch aktiven Eiern bei der Darmpassage intakt. These have the same transit or residence in the intestines, however, remain intact in contrast to the embryonated eggs and biologically active in the intestinal transit. Durch Markierung der als interner Standard vorgesehenen Eiern mit einem zweiten unterschiedlichen Fluoreszenzfarbstoff kann leicht zwischen dem internen Standard und den zu untersuchenden Eiern unterschieden werden.

By indicating the provided as an internal standard eggs with a second different fluorescent dye can be easily distinguished between the internal standard and the eggs to be examined. The hatching rate in the intestine can be as follows based on the intact unhatched Calculate eggs.

In a preferred embodiment, the new test method covers the determination of the temperature-induced activation capacity of embryonated helminth eggs in vitro. The in vitro activity score indicates a good correlation to the biological activity in vivo. Wie die Analyse auf helminth Eier zu über, it is only prediktiv for biological activity, when the larvae are fully employed embryoniert.

To this is added a quantitative PCR method used, which measures the number of copies of bloodut5368.xsl.pt- genome in the egg. Schematisch stellt sich das bevorzugte Verfahren dar, wie folgt: Schematically represents the preferred process, as follows: Ein wichtiger Aspekt der vorliegenden Erfindung ist die Bestimmung der temperaturinduzierten Aktivierbarkeit in vitro.

An important aspect of the present invention is to determine the temperature-induced activation ability in vitro. Unexpected and previously described, it was found that the eggs in vitro only can be activated by incubation for a certain period in a certain temperature window without the addition of other factors.

The activated state of the eggs is by determining two complementary parameters quantified: the motility of the larvae within the intact eggs as well as the determination of the ATP content of lysates previously activated eggs. Unerwartet und im Gegensatz zu dem in der Literatur beschrieben Verhalten, induziert die hier beschriebene Vorinkubation subtile Bewegungen der Larve im Ei.

Unexpectedly and in contrast to the behavior described in the literature, induces the preincubation described herein subtle movements of the larva in the egg.

The movement of the larvae lasts for hours without the larvae die or hatch from the egg. Therefore, a preferred embodiment of the process illustrated here, a suitable pre-incubation of the eggs, which leads to activation. About a microscopic observation of a sufficiently large number of eggs in fast motion succeeds reliably to determine the proportion of eggs in the population which contain an active, motile larva Motility Index.

Both study parameters of motility than direct, but discontinuous and the ATP content as an indirect but continuos size combine to provide a reliable determination of in Vitro activity, which correlates well with the in vivo activity. For both parameters in vitro activity score can be calculated, which correlates well with the in vivo activity of the eggs.

The invention in vtfro method differs significantly from the previously known methods. The determination of Embryonierungsrate be examined purely visually for the presence of fully formed larvae in the eggs kringle et al. The determination of hatching in vitro simulation of the stomach and intestinal passage appears compared with the method more complex and failure-prone shown here.

In the preferred embodiment of the invention, the Embryonierungszustand is determined. Incomplete developed larvae react in the test for temperature-induced activation capacity may positively, but are not functional and would not slip into the situation in the host and to follow the normal life cycle of the larvae. A complete embryonic development is evaluated microscopically based on morphological criteria in the previously known methods.

This assessment requires great experience, is uncertain and may occur naturally only in individual eggs. The method according to the invention measures against it objectively, the copy number of the genome in a large egg-population from which the mean number of somatic cells can be calculated per larva.

Wie die Analyse auf helminth Eier zu über results of tests on temperature-induced activation capacity preferably backed by a novel in vivo test which determined in a simple and fast way reliably the hatching rate under physiological conditions.

Surprisingly, it was Джезераку, Welpen Würmer 1 Monat счастью that larvae of biologically active eggs hatch in the wie die Analyse auf helminth Eier zu über quantitatively while previously inactivated eggs intestinal transit through unchanged. In the newly developed method, the proportion of active TSO is indirectly determined in a preparation by only the inactive eggs are counted, who happen to Intestinaltakt an experimental animal unchanged.

Quantification can only succeed through a newly developed internal standard consisting of fluorescently labeled inactive eggs, which also happens unchanged the intestinal tract. Surprisingly and als die Ausgabe von Würmern in Kaninchen, has also been found that biologically active TSO slip quantitatively also in the intestine of the rabbit. Thus, is to replace the pig, an animal model available, which is to maintain cost-effective and simple and the advantage of a wie die Analyse auf helminth Eier zu über smaller intestinal volume has, which facilitates the recovery of microscopic wie die Analyse auf helminth Eier zu über. The invention in vivo test sets itself apart from the known infectivity in Pig.

In addition, is only the first step of the life cycle of T. A further advantage of the assay illustrated here is that the eggs may be recovered from the faeces of the animals and the animals do not therefore have to be killed for the test. Die Zielsequenz, die Primer und die TaqMan-Probe sind nachfolgend dargestellt. The target sequence, the primers and the TaqMan probe are shown below. The target sequence was selected so that they suis and other Trichuris spp allows differentiation between Trichuris whose sequence is also known.

Microscopic inspection showed that the embryonic membranes can completely break surprisingly with this method, while other conventional gene isolation in the pulping wie die Analyse auf helminth Eier zu über in eggs of Trichuris suis remain unsuccessful.

Die Ergebnisse sind in der folgenden Tabelle dargestellt. The results are shown in the following table. For the related organism C. Somit eignet sich dieses Verfahren besonders um den Verlauf der Embryonierung prozess-beg leitend zu analysieren.

Thus, this method is particularly suitable wie die Analyse auf helminth Eier zu über the course of embryonation analyze process-beg conductive. For the detection of wie die Analyse auf helminth Eier zu über triphosphate are commercially available kits are available that contain the information necessary for the reaction luciferase enzymes and the substrate luciferin and magnesium salts among others.

Die Stimulation der Adenosintriphosphat-Bildung durch Wie die Analyse auf helminth Eier zu über der embryonierten Eier ist zwingend erforderlich. Stimulation of wie die Analyse auf helminth Eier zu über triphosphate formation by pre-incubation of embryonated wie die Analyse auf helminth Eier zu über is imperative.

A significant advantage of the developed method learn more here analysis is that no sample preparation is required for this incubation. The present egg suspensions can be used irrespective of whether the qualitative and quantitative composition of the medium. Active embryonated eggs of T. Thus represents the activity test a gene available, the expression of which can be actively induced by selecting suitable experimental conditions.

By fluorescent labeling of the active eggs the analysis of the egg-population can be investigated by means of flow cytometry. Opposite the microscopic analysis, the advantage is that the analysis is faster and more objectively. The example clearly shows that the induction of gene expression in individual helminth ova can be studied with the methods described herein.

Probably the motility of the larvae has not been observed in the egg, because a long pre-incubation is necessary and the slow movements are only visible in fast motion. The comparison of active and inactivated eggs clearly shows that it is possible by examining the motility suis eggs differentiate easily between biologically active and inactive Trichuris.

Charakteristisches und neuartiges Merkmal dieses Verfahrens sind also die Aktivierungsphase mit exakter Temperaturkontrolle sowie das lange Beobachtungsfenster. Characteristic and novel feature of this method are therefore the activation phase with precise temperature control and the long observation windows. The measurement results are listed in the following tables.

The motility is the infectivity test so far superior to both the reproducibility and the precision. In order to obtain objective counts, the samples were allied before measurement. The relative biological activity was calculated by dividing the measured motility index of the sample and the previously determined motility of active TSO.

The accuracy of the measurement results from the comparison relative biological activity and the actual percentage of active eggs in the sample. An analogous series of measurements with TSO from the same batch was carried out with the infectivity. The test animals were infected with different amounts of active TSO with known infectivity. Auf eine Zumischung von inaktivierten Eiern wurde verzichtet.

In an check this out of inactivated eggs were dispensed with. The results are shown in the next tables.

The example clearly shows that the motility correlates linearly with the relative biological activity. Exemplary rabbits were administered various mixtures of embryonated, non-embryonated and inactivated, embryonated eggs orally. Dies belegt eindeutig, dass man mit dem Verfahren zwischen biologisch aktiven und inaktivierten Eiern differenzieren kann. This clearly demonstrates that one can differentiate by the process between biologically active and inactivated eggs.

This allows use of non-embryonated eggs as an internal standard of the intestines of animals passes through without being degraded. This internal standard is necessary because the recovery of the eggs in the intestinal contents is incomplete and thus the absolute number of recovered intact eggs is not meaningful. To calculate the hatching rate, taking into account the internal standard, the above mentioned formula is used.

Um eine bessere Wiederfindung und eine klarere Differenzierung zwischen den Eiern der Probe und den Eiern des internen Standards zu erzielen, wurden Trichuris suis Eier mit einer Fluoreszenz-Sonde kovalent markiert. In order to obtain a better recovery and a clearer differentiation between the eggs and the eggs of the sample of internal standard, Trichuris suis were marked eggs covalently with a fluorescent probe.

Fluorescence microscopy clearly shows the red color of the egg-shell Fig. The fluorescent label can advantageously be used for microscopic analysis of hatching. It also provides the opportunity for objective and rapid analysis by fluorescence-activated flow cytometry. Overall, the example clearly shows that the can examine the phase of hatching quantitatively and use for determining the biological activity by the method described here.

The samples were initially investigated by the PCR method to the integrity of the embryonic development. Subsequently, the motility and ATP content was determined by temperaturinduzeirter activation.

The infectivity was after at kringle et al. The example shows a good correlation of the in vitro activity scores with the biological activity in vivo. Slight variations in individual samples are more likely the result of weaknesses in vivo tests, the related with the biological variability host factors instrinsischen uncertainty wie die Analyse auf helminth Eier zu über fraught.

Method for characterising the biological activity of helminth eggs, in particular trichuris eggs. The intact embryonic eggs recovered from the contents of the intestine are quantified according to international standards.
