Definitions
- the present invention relates to a test agent for testing adult infections of tapeworms and tapeless tapeworms, and a method of testing these drugs.
- Taenia solium is a parasite in the gastrointestinal tract of humans that ingests pork, etc. containing its larvae (called Cysticercus cellulosae) in its muscles without passing through sufficient heat. It is a "tamandid that grows several meters long like a kishimen.” Cygnus cysts (hereinafter abbreviated as cysts) develop throughout the body of humans and pigs that orally ingest eggs that are excreted from humans harboring the adults. Infection of striated tapeworms in humans is basically due to ingestion of “porcine meat infected with cysts”.
- Taenia saginata has the same structure and life cycle as those of Taenia saginata and has few symptoms.
- Non-Patent Document 1 hydrophobic ligand binding protein (HLBP) is a low-molecular-weight protein with a molecular weight of about 10 kDa, which is unique to tapeworms. But its detailed function was unknown (Non-Patent Document 2)
- Non-Patent Document 1 Inspection and Technology Vol. 26, No. 4, 391-393 (1998)
- Non-Patent Document 2 FEBS Letters 487 (2000) 181-184
- HLBP adult-derived hydrophobic ligand binding protein
- the present invention relates to an amino acid sequence containing at least the 22nd to 65th amino acids of the 20th to 85th amino acid sequences of any of SEQ ID NOs: 14 (that is, any one of SEQ ID NOs: 14 to 14). It is a test drug for adult infection of tapeworms and tapeworms whose main component is a peptide consisting of the amino acid sequence of amino acids 20 to 22 to 65 to 85) or SEQ ID NO: 5.
- the present invention is a method for detecting adult infection with tapered tapeworms and tapeless tapeworms, which comprises reacting the serum of a subject (human) with the above-mentioned test drug.
- the present invention also provides a peptide comprising an amino acid sequence containing at least the 22nd to 65th amino acid sequence of any of the 20th to 85th amino acid sequences of any of SEQ ID NOs: 14 or SEQ ID NO: 5; And then reacting it with the serum of the subject, reacting it with a labeled probe, and detecting this label. It is.
- the present invention relates to a test kit for detecting adult infection of tapeworms and tapeworms with a serum power of a subject, wherein the test kit comprises any one of SEQ ID NOS: 14 fixed to a support.
- This test kit has an amino acid sequence containing at least the 22nd to 65th amino acids of the 85th amino acid sequence or the amino acid sequence of SEQ ID NO: 5 and the peptide power.
- test agent or antigen peptide of the present invention is considered to be extremely effective in serodiagnosis of humans. If the test agent of the present invention is applied to an antibody measurement system, the presence or absence of an adult infection can be determined by detecting a specific antibody from a test subject.
- Anchodiasis and arborealis are mild diseases as they only involve an adult in the digestive tract. However, adult infected people will pollute the living environment as egg sprayers without their knowledge. In particular, in the case of tapeworm, when scattered eggs are ingested by others, the larvae can invade the central nervous system (cysticercosis).
- Tapeworms and tapeworms are not rare diseases in developing countries, and tapeworms are particularly important in public health as they cause cysticercosis. Since humans are the only end hosts for these parasites, eradication is possible if adult carriers can be efficiently detected and anesthetized.
- test reagents and test methods of the present invention are thought to contribute to the efficiency of mass screening of migrants from endemic areas in developed countries.
- HLBP hydrophobic ligand binding protein
- Moniezia expansa (Mexp, SEQ ID NO: 7) was isolated for the first time from a tapeworm of Hedge (Non-Patent Document 1, 2403292A). Both are proteins derived from adults.
- Hdim and Mexp adult HLBPs (AHLBPs) and the hook-free tapeworms obtained by the present inventors (AHLBPs)
- Taenia saginata (abbreviated as Tsag) Different from adult AHLBP (40-49% homology).
- Tsag_AHLBP_c20 (SEQ ID NOs: 1, 8) of the adult tape-free tapeworm obtained by the present inventors,
- Table 1 shows a comparison between Tsag_AHLBP_c35 (SEQ ID NOS: 4,11) and exon (Tsol_exon) of adult barculates (SEQ ID NOs: 5, 12). [table 1]
- HLBP adult HLBP
- Tsag tapeworm
- Tsol tapeworm
- the present inventors used RT-PCR to compare what HLBP gene is expressed between the larval stage and the adult stage, using a tapeworm as a model. As a result, although various HLBP genes were expressed during the larval stage, it was confirmed that these larval HLBP genes were not expressed at all in adults. Then, when a cDNA library of the adult tapeworm was searched, it was possible to clone an adult HLBP gene having a homology different from that of the larval HLBP gene (Examples 1 and 2).
- HLBP molecules belonging to the same family were present in larvae and adults, and their expression was strictly controlled during the larval and adult stages. This means that the larval and adult antibody responses can be detected separately using each HLBP molecule as an antigen.
- a recombinant protein of E. coli was produced using the cleaved adult HLBP gene and reacted with the sera of adults without infected tapeworms or tapeworms. The molecule was proven to be antigenic, helping to use it as a diagnostic antigen.
- the test agent (antigen) of the present invention is used to react with an antibody produced in a subject (human) infested with a tape-less tapeworm or a tape-shaped tapeworm, thereby obtaining a tape-less tapeworm or a hook. It can be tested for the presence of tapeworm parasitism. Examples of such a test subject include serum, urine, and the like of a subject, and preferably use serum. If the test subject is parasitized with a tape-less tapeworm or a tapeworm, the antibody reacts with the antigen because the antibody is produced and present in the serum.
- the method for detecting the antigen-antibody reaction is not particularly limited, and examples thereof include an immunoblot method, a dot plot method, and an ELISA method.
- a preferable test method for a tape-less tapeworm or a tape-shaped tapeworm is to immobilize the antigen of the present invention on a support, react it with the serum of a subject, and react it with a labeled probe. And detecting this label.
- a washing step is appropriately inserted between each step.
- the support is not particularly limited, but polystyrene or the like can be used.
- This antigen is reacted with an antibody present in the serum of a subject (when a tape-less tapeworm or parasitoids is parasitized), and further reacted with a probe that recognizes this antibody.
- probes include anti-human HgG antibodies, protein G, protein A, protein L, and the like.
- This probe is usually labeled.
- the label includes a radioisotope ( 12 12 , an enzyme (peroxidase, alkaline phosphatase).
- an enzyme antibody is used, a change in the substrate (eg, coloration) can be observed by reacting the substrate. .
- the antigen of the present invention can be synthesized, and therefore can be conveniently and stably supplied as a test antigen, and quality control is easy.
- the degenerate primer (FYDEDPL (SEQ ID NO: 16) where the amino acid sequence is conserved in adult HLBP (Non-Patent Document 1, 2403292A)
