Description
Technical field
The invention belongs to Medical Immunology diagnostic techniques fields, and in particular to MS4A3 albumen is lived as marker in diagnosis
Application in dynamic property tuberculosis.
Background technique
Tuberculosis is infectious disease caused by mycobacterium tuberculosis (Mycobacterium tuberculosis, MTB), mainly
Pass through respiratory infectious.It may occur in which three kinds of different as a result, first is that immunity of organisms is preferable, MTB directly quilts after MTB infection human body
It removes；Second is that MTB is inhibited by immunity of organism, but can not be fully erased, develop as tuberculosis latent infection (latent
Tuberculosis infection, LTBI)；Third is that MTB is proliferated rapidly in body, active tuberculosis is developed into.Tuberculosis
Disease is the serious infectious diseases that China needs emphasis prevention and control.
Diagnosis of tuberculosis mainly has the methods of imaging diagnosis, tulase diagnosis and immunology diagnosis at present, but has one
Fixed disadvantage.Imaging diagnosis is difficult to differentiate between pulmonary tuberculosis and other pulmonary diseases.It is high that tulase diagnoses false negative.Immunology is examined
It is disconnected mainly divide antibody test and cellular immunity detect (such as tuberculin skin test (tuberculin skin test, TST) and
Interferon release test (interferon gamma release assays, IGRA)).TST and IGRA is to pass through detection
The immune main treating tuberculosis of body is cellullar immunologic response to evaluate tuberculosis infection situation.The country is existing mostly by TST as main inspection
Survey means, generally by purified protein derivative (PPD) (PPD) strong positive or in a short time from feminine gender switch to it is positive and without clinical tuberculosis evidence
Person is judged as tulase latent infection person.Due to TST feature be it is easy to operate, cheap, have become at present clinically most
A kind of common and the simplest tubercle bacillus affection diagnostic method.But PPD is the antigen mixture slightly mentioned from mycobacterium tuberculosis,
Comprising 200 multiple proteins, wherein being much the common antigen ingredient of non-tuberculous mycobacteria and BCG vaccine, therefore TST is determined
Poor specificity is detected, is also easy to produce false positive results in BCG vaccine (BCG) inoculation crowd and non-tuberculous mycobacteria infection population.
TST can only only have 70-80% according to the reaction power auxiliary diagnosis of skin, sensitivity.In addition TST there are when check fee, need
It wants subject to pay a return visit (72h), skin test operation and result and explains there is the disadvantages of subjective dependence.IGRA is inhaled using enzyme linked immunological
Adhesion test (ELISA) or Enzyme linked immunospot (ELISPOT) method quantitatively detect subject's whole blood or the single core of peripheral blood
IFN-γ detection release reaction of the cell to Specific Antigen of Mycobacterium Tuberculosis (ESAT6, CFP10 and TB7.7), for
The diagnosis of tubercle bacillus affection, but IGRA is difficult to differentiate between active tuberculosis and latent tuberculosis infection.Activity cannot be early diagnosed
Property tuberculosis, on the one hand lead to delay treatment, increase medical expense and the death rate；On the other hand it not can be effectively controlled the infection sources,
Cause diffusion lungy.Therefore, special, effective active tuberculosis diagnostic reagent is developed to tuberculosis prevention and treatment with important
Meaning.
Studies have shown that MS4A3 albumen may be related to the proliferation of leukaemia cell；MS4A3 albumen is in breast cancer, oophoroma
There are significant differences with the expression in the expression and normal tissue in prostate cancer.
