Antigen Receptor Cov noob

Cov nab npawb ntawm cov noob los ntawm cov cheeb tsam sib txawv tau tsim muaj loj txaus uas ob lub B thiab T hlwb tuaj yeem tsim ntau dua 107 txawv antigen - khi qhov chaw.

Cov lus nug tseem yog, pes tsawg hom antigens muaj?

Antigens ua tau ntawm 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.

Ib qho ntxiv, hom kab mob hauv lub cev twg muaj cov tshuaj tiv thaiv antigen? Muaj yog peb lub ntsiab hom ntawm antigen -kev nthuav qhia hlwb nyob rau hauv peripheral lymphoid kab mob uas tuaj yeem qhib T hlwb -mob plab hlwb , macrophages, thiab B. hlwb . Qhov muaj zog tshaj plaws ntawm cov no yog dendritic hlwb (Daim duab 24-43), uas nws tsuas paub muaj nuj nqi yog nthuav tawm txawv teb chaws antigens rau T. hlwb.

Khaws qhov no hauv kev xav, dab tsi yog antigen receptors?

lub luag haujlwm hauv kev tiv thaiv An antigen tus txais yog qhov tseem ceeb ntawm cov tshuaj tiv thaiv kab mob uas tsis zais tab sis tau muab khi rau B-cell membrane. Txhua antigen cov neeg txais pom ntawm qhov tshwj xeeb B cell zoo ib yam, tab sis cov receptors nyob rau lwm lub hlwb sib txawv.

Muaj pes tsawg tus T cell receptors muaj?

Ib qho raug T tes tej zaum muaj li ntau li 20,000 tus txais molecules ntawm nws daim nyias nyias, txhua yam ntawm alpha-beta lossis gamma-delta yam. Lub hauv paus qauv ntawm ib tug raug T - ntawm tes antigen tus txais.
