Antigenic tshwj xeeb yog lub peev xwm ntawm cov cell kom paub txog cov antigen los ntawm nws cov qauv molecular tshwj xeeb, xws li kev sib raug zoo ntawm antigen epitopes thiab antibody paratopes.
Lub ntsiab lus ntawm cov proteins antigenic yog dab tsi?
: txhua yam khoom (xws li cov tshuaj tiv thaiv kab mob lossis tshuaj tiv thaiv kab mob) txawv teb chaws rau lub cev uas ua rau lub cev tiv thaiv kab mob ib leeglossis tom qab tsim cov txheej txheem nrog cov molecule loj dua (xws li ib qho protein) thiab uas muaj peev xwm los khi nrog ib yam khoom (xws li tshuaj tiv thaiv kab mob lossis T cell) ntawm lub cev tiv thaiv kab mob.
Dab tsi yog antigenic receptor?
Ib qho tshuaj tiv thaiv kab mob yog qhov tseem ceeb an antibody protein uas tsis zais tab sis yog anched rau B-cell membrane. Tag nrho cov antigen receptors pom ntawm ib qho B cell zoo ib yam, tab sis cov receptors nyob rau lwm lub hlwb sib txawv.
Ib qho piv txwv ntawm kev hloov pauv tshuaj tiv thaiv yog dab tsi?
Piv txwv ntawm qhov sib txawv ntawm cov tshuaj tiv thaiv kab mob sib txawv yog cov uas tshwm sim hauv cov kab mob xws li tus kab mob khaub thuas thiab tus kab mob tib neeg tiv thaiv kab mob (HIV), uas ua rau kis tau tus kab mob tiv thaiv kab mob (AIDS). Cov tshuaj tiv thaiv tseem ceeb ntawm cov kab mob no yog glycoproteins uas ua rau lawv lub tsho tiv thaiv kab mob.
Dab tsi yog antigen yooj yim txhais?
(AN-tih-jen) Txhua yam khoom uas ua rau lub cev ua rau lub cev tsis muaj zog tiv thaiv cov khoom ntawd. Antigens muaj xws li co toxins, tshuaj, kab mob, kab mob, los yog lwm yam khoom uas los ntawm sab nraum lub cev.
