Description

A kind of test kit for autoimmune disease detection
Technical field
The present invention relates to biological technical field, particularly to a kind of test kit for autoimmune disease detection.
Background technology
Toll-like receptor (Toll-like receptors, TLR) is the classical mode identification receptor of inherent immunity cell, It identifies pathogen-associated molecular pattern, starts innate immune response, and determines follow-up adaptive immune response direction and reaction Intensity, thus by the strict regulation and control of body immune system.The immunoregulation of TLR signal includes negative regulation and is just regulating and controlling, and marrow Like cell expresses triggering receptor (Triggering receptor expressed on myeloid cells, TREM) family The member of the one newfound immunoglobulin superfamily of class, TLR signal immunoregulatory molecules, can be by amplifying or suppression TLR letter Number thus regulate and control immune response intensity, avoid the generation of excessive inflammatory response and autoimmune disease.TREM family at present Race contain TREM-1, TREM-2, TREM-3, TREM sample transcription factor 1 (TREM like transcript1, TLT-1) and Many Receptor member of TLT-2, wherein TREM-1 can strengthen inflammatory reaction, positive regulation autoimmune disease develops; In contrast, TREM-2 is main in autoimmune plays negative regulation effect, the differentiation and maturation of scalable various kinds of cell;And for TLT-1, the most more thinks that it is a Class Activation receptor, participates in platelet activation, the process of gathering;Similar, TLT-2 Leukocyte activation can be promoted, T cell is had stimulation.TREM-1 is the TREM family activated form receptor of report in 2000, and And along with the research to its mechanism of action, find that it plays important work in part autoimmune disease develops With, now a summary is made with regard to TREM-1 molecule and the progress in autoimmune disease thereof.
It has now been found that TREM gene mapping is in No. 6 chromosomes of people.Outside first Bouchon etc. find that TREM-1 is expressed in Neutrophilic granulocyte in week blood, the inherent immunity cell surface such as mononuclear cell, the transmembrane glycopeptide being made up of 234 aminoacid In vain, which includes extracellular region, cross-film district containing lysine residue and the shortage being made up of independent immunoglobulin V-structure territory The intracellular region in intrinsic signal territory.Increasing research display TREM-1 also can express at natural killer cell, dendron in recent years Shape cell, airway epithelial cell, hepatic endothelial cells etc..
TREM-1 is mainly with membrane surface molecule and shla molecule (Soluble TREM-1, sTREM-1) two kinds expression Form exists.After the TREM-1 molecule on film surface is combined with part according to its construction features, activate a series of signal path, adjust Control inflammatory reaction and induction immunne response.There are two kinds of hypothesis in source for sTREM-1 at present: one is that TREM-1 shears variation Lacking the secretion hypotype in cross-film district, two is the result under the TREM-1 Proteolytic enzyme mechanism of film surface, and tests proof on antibacterial Lipopolysaccharide (Lipopolysaccharides, LPS) stimulate under person monocytic cell and neutrophilic granulocyte cultivation in, metal egg White enzyme inhibitor can increase the stability of cell surface TREM-1, reduce the release [5] of sTREM-1.Although TREM-1's is natural Part determines the most completely, but it expresses at human blood platelets surface and Peritonitis, endotoxemia little to have research to speculate Surfaces of granulocytes in mouse model, but to obtain definite answer, still need to further study confirmation.
Prior art has had substantial amounts of evidence to show TREM-1 and systemic lupus erythematosus (sle) (Systemic lupus Erythematosus, SLE) there is great dependency.SLE is the autoimmune disease of a kind of diffusivity, general, Principal pathogenetic mechanism is the formation of autoantibody and immune complex, often involves multiple organ and system in disease progression. The cause of disease of SLE and pathogenesis are complicated, diverse clinical manifestations, and infection is one of reason of disease triggering, is also to fall ill simultaneously Journey increases the weight of the common factors of the state of an illness.There is research that SLE fever patient is divided into disease activity group and concurrent infection group, by detection In patients serum, sTREM-1 level finds that concurrent infection patient is apparently higher than disease activity patient.And up-to-date research report Road is pointed out, sTREM-1 is up-regulated in SLE patients serum.
Prior art detects the amount of TREM-1 albumen typically by being carried out by enzyme linked immunoassay after antibodies Detection by quantitative, but this detection method needs to provide corresponding antibody for oneself, owing to the preparation of antibody requires higher, and prepares multiple Miscellaneous, there is huge limitation in the detection.
SELEX technology is a kind of new combinatorial chemistry technique grown up early 1990s.Utilize this technology can The aptamer affine with target substance height to screen specificity from random single chain oligonucleotide library.Its basic ideas are One single stranded oligonucleotide storehouse of iii vitro chemical synthesis, mixes with target substance, forms target substance-nucleic acid complexes, and eluting is not associated with Nucleic acid, separate the nucleic acid molecules that is combined with target substance, and carry out PCR amplification with this nucleic acid molecules for template, enter back into lower whorl Screening.By the screening repeated and amplification, some are not combined or have with target substance low-affinity, middle affinity with target substance Nucleic acid molecules is washed away, and with leather G material have the nucleic acid molecules of strong affinity from the biggest with hangar point the most out, and pure Spend carrying out and increase with SELEX process, finally occupy the great majority (> about 90% in storehouse).From Tuerk and Ellington etc. First use this technology screening to specific adsorption phage T4DNA polymerase and the specific nucleic acid aptamers of organic dye molecule After, through the development of more than ten years, SELEX technology has become as a kind of important grinds the means of making internal disorder or usurp and instrument.Therefore, selex is used Technology, screening specifically combines the aptamers of TREM-1 and has the most important meaning.
