antigen . Ib antigen yog ib qho molecule uas txhawb kev tiv thaiv kab mob. Pathogen-associated molecular qauv ( PAMPs ) yog cov txheej txheem me me uas tsis tu ncua pom ntawm cov kab mob uas tau lees paub los ntawm Toll-like receptors (TLRs) thiab lwm yam qauv lees paub tus txais (PRRs).

Hauv qhov no, cov piv txwv ntawm PAMPs yog dab tsi?

Qhov zoo tshaj plaws-paub piv txwv ntawm PAMPs suav nrog lipopolysaccharide (LPS) ntawm cov kab mob gram-negative; lipoteichoic acids (LTA) ntawm cov kab mob gram-zoo; peptidoglycan; lipoproteins tsim los ntawm palmitylation ntawm N-terminal cysteine ntawm ntau cov kab mob cell phab ntsa proteins; lipoarabinomannan ntawm mycobacteria; ob-stranded RNA

Tom qab ntawd, lo lus nug yog, puas yog haptens antigens? Haptens . A hapten yeej tseem tsis tiav antigen . Cov molecules me me no tuaj yeem ua rau lub cev tiv thaiv kab mob tsuas yog thaum txuas nrog cov cab loj xws li cov protein; tus cab kuj feem ntau tsis ua txhaum cai tiv thaiv kab mob los ntawm nws tus kheej.

Hauv qhov no, 3 hom antigens yog dab tsi?

Antigens feem ntau yog cov protein. Tab sis lawv tuaj yeem yog lipids, carbohydrates lossis nucleic acids. Antigens tuaj yeem yog peb hom - Exogenous, endogenous thiab autoantigens. Antigens kuj tuaj yeem yog lub cev txawv teb chaws uas txhawb kev tiv thaiv kab mob hauv lub cev.
