CD3 (pawg ntawm qhov sib txawv 3) yog cov protein ntau thiab T cell co-receptor uas koom nrog ua kom ob leeg cytotoxic T cell (CD8 + naive T cells) thiab T pab hlwb (CD4 + naive T hlwb). … Lub TCR, CD3-zeta, thiab lwm yam CD3 molecules ua ke ua tus TCR complex.
YPuas CD3 yog antigen?
Cov CD3 antigen yog cov qauv txheej txheem cuam tshuam nrog T-cell receptor (TCR) los tsim ib qho kev koom tes hauv kev lees paub antigen thiab teeb liab hloov.
CD3 hauv T cells yog dab tsi?
CD3 yog a multimeric protein complex, uas yog tsim los ntawm plaub qhov sib txawv (CD3g, CD3d thiab ob CD3e). CD3 ntawm lub xovtooj ntawm tes cuam tshuam nrog T-cell antigen receptor (TCR) ua haujlwm hauv lub teeb liab hloov pauv uas tshwm sim thaum peptide - MHC ligand khi rau TCR.
TCR CD3 complex yog dab tsi?
Tus ntau-chain T cell receptor / CD3 complex (TCR / CD3) plays lub luag haujlwm tseem ceeb hauv kev lees paub antigen, T cell ua kom muaj txiaj ntsig thiab ua rau ua rau muaj kev tiv thaiv antigen tshwj xeeb. teb.
T cells qhib dab tsi?
Pab T hlwb yog sib cav tias cov hlwb tseem ceeb tshaj plaws hauv kev tiv thaiv kab mob, raws li lawv xav tau rau yuav luag txhua qhov kev tiv thaiv kab mob. Lawv tsis tsuas yog pab qhib B hlwb txhawm rau zais cov tshuaj tiv thaiv kab mob thiab cov macrophages los rhuav tshem cov kab mob nkag mus, tab sis lawv kuj pab qhib cytotoxic T hlwb kom tua cov kab mob.
