Antigens tau hais tawm hauv daim ntawv sib xyaw / sib saunthuav tawm cov khoom tiv thaiv kab mob sib txawv ntawm cov tshuaj tiv thaiv sib xws hauv daim ntawv soluble. Cells uas muaj phagocytic kev ua ub no tau xaiv nyob rau hauv particulate antigens thiab ua li ntawd nrog kuj high efficiency.
Dab tsi yog qhov txawv ntawm soluble antigen thiab particulate antigen?
Lub cev daim ntawv ntawm cov tshuaj tiv thaiv
Yog cov tshuaj tiv thaiv yog ib feem, feem ntau saib rau agglutination ntawm antigen los ntawm cov tshuaj tiv thaiv. Yog hais tias cov antigen yog soluble ib feem ntau saib rau nag lossis daus ntawm antigen tom qab tsim cov loj insoluble antigen-antibody complexes.
3 hom antigens yog dab tsi?
Muaj peb yam tseem ceeb ntawm cov tshuaj tiv thaiv
Peb txoj kev dav los txhais cov tshuaj tiv thaiv muaj xws li exogenous (tawm txawv teb chaws rau lub cev tiv thaiv kab mob), endogenous (tsim los ntawm intracellular Cov kab mob thiab tus kab mob replicating nyob rau hauv ib lub cell cell), thiab autoantigens (tsim los ntawm tus tswv tsev).
4 hom tshuaj tiv thaiv dab tsi?
Muaj ntau hom antigens raws li keeb kwm:
- Exogenous Antigens. Exogenous antigens yog cov tshuaj tiv thaiv sab nraud uas nkag mus rau hauv lub cev los ntawm sab nraud, xws li. inhalation, txhaj tshuaj, thiab lwm yam …
- Endogenous Antigens. …
- Autoantigens. …
- Tumour Antigens. …
- Native Antigens. …
- Immunogen. …
- Hapten.
5 hom yog dab tsiantigens?
The 5 hom - IgG, IgM, IgA, IgD, IgE - (isotypes) raug cais raws li hom ntawm cov saw hnyav tas li, thiab faib thiab ua haujlwm sib txawv hauv lub cev. IgG yog cov tshuaj tiv thaiv tseem ceeb hauv cov ntshav.
