Yog tias koj tau raug rau HIV , antigens yuav tshwm sim hauv koj cov ntshav ua ntej HIV tau tsim cov tshuaj tiv thaiv kab mob. Qhov kev kuaj no feem ntau tuaj yeem pom HIV tsis pub dhau 2-6 lub lis piam tom qab kis kab mob. Cov HIV tshuaj tiv thaiv / antigen xeem yog ib qho ntawm feem ntau hom ntawm HIV kuaj.
Ntxiv rau qhov no, HIV antigen txhais li cas?
HIV antibody thiab HIV antigen (p24) xeem yog siv los tshuaj xyuas thiab kuaj mob HIV kab mob. Thaum Ntxov nrhiav kom tau thiab kev kho mob ntawm HIV kev kis tus kab mob thiab kev tiv thaiv kab mob hauv lub cev tuaj yeem txhim kho kev noj qab haus huv thiab kev nyob ntev. Nws ntes cov HIV antigen hu ua p24 plus antibodies to HIV -1 thiab HIV -2.
ntev npaum li cas p24 antigen kuaj tau? Thawj HIV protein ( antigen ) uas tuaj yeem ntsuas tau yog p24 ua (los ntawm 1 txog 8 lub lis piam tom qab kis tau). Viral load thiab p24 ua kev ntsuam xyuas tsis raug rau kev kuaj mob HIV ntxov yog tias cov txiaj ntsig tsis zoo. Cov tshuaj tiv thaiv kab mob HIV tuaj yeem ua tau kuaj pom thaum ntxov li ob lub lis piam hauv ob peb tus neeg thiab ntau dua 99.9% ntawm cov neeg los ntawm 12 lub lis piam.
Ua raws li qhov xav tau, cov tshuaj tiv thaiv kab mob HIV yog dab tsi?
Cov tshuaj tiv thaiv yog cov protein tsim los ntawm koj lub cev thaum koj kis tus kab mob thiab lawv pab tiv thaiv kab mob. Yog koj kis tau HIV , koj lub cev ua kom meej heev tshuaj tiv thaiv tiv thaiv kab mob. Cov Cov tshuaj tiv thaiv kab mob HIV yog txawv los ntawm tshuaj tiv thaiv rau kab mob khaub thuas, kab mob siab, lossis lwm yam kab mob.
Koj puas tuaj yeem muaj cov tshuaj tiv thaiv kab mob HIV thiab tsis muaj HIV?
Cov txiaj ntsig ib txwm yog qhov tsis zoo. Qhov no txhais tau tias tsis muaj tshuaj tiv thaiv tau pom thiab ntawd koj tej zaum tsis kis nrog HIV . Cov neeg feem coob uas kis mob HIV yuav txhim kho tshuaj tiv thaiv mus rau tus kab mob hauv 2 lub hlis. Lub sijhawm no, koj tej zaum muaj HIV tab sis qhov kev xeem no tau 'tsis ntes nws.

Dab tsi yog glycoprotein dab tsi yog ib qho ntawm kev siv glycoproteins?
Glycoproteins yog cov protein uas muaj cov oligosaccharide saw (glycans) covalently txuas nrog cov amino acid sab-saw. Glycoproteins kuj tseem yog ib qho tseem ceeb ua ke ntawm cov protein, uas lawv ua lub luag haujlwm hauv kev sib cuam tshuam ntawm tes -cell
Antigens thiab tshuaj tiv thaiv kab mob yog dab tsi?
Antigens yog cov lwg me me muaj peev xwm txhawb kev tiv thaiv kab mob. Txhua tus antigen muaj cov yam ntxwv sib txawv, lossis epitopes, ua rau muaj cov lus teb tshwj xeeb. Cov tshuaj tiv thaiv kab mob (immunoglobins) yog cov protein zoo li Y tsim los ntawm B hlwb ntawm lub cev tiv thaiv kab mob hauv kev teb rau kis rau antigens
HIV sawv rau dab tsi yog HIV?
HIV sawv cev rau Human Immunodeficiency Virus. Nov yog tus kab mob ua rau mob AIDS. HIV tshwj xeeb los ntawm cov kab mob feem ntau vim nws tawm tsam koj lub cev tiv thaiv kab mob. Lub cev tiv thaiv kab mob ua rau peb lub cev muaj peev xwm tiv thaiv kab mob
Dab tsi yog antigens nyob rau hauv cov ntshav?
Ob qhov antigens yog antigen A thiab antigen B. Ob qhov tshuaj tiv thaiv yog antibody A thiab antibody B. Cov antigens muaj nyob ntawm cov qe ntshav liab thiab cov tshuaj tiv thaiv hauv cov ntshav
Dab tsi yog exogenous antigens?
Exogenous antigens yog antigens uas tau nkag mus rau hauv lub cev los ntawm sab nraud, piv txwv li, los ntawm kev nqus pa, nqus los yog txhaj tshuaj. Los ntawm endocytosis los yog phagocytosis, exogenous antigens raug coj mus rau hauv cov antigen-presenting cells (APCs) thiab ua tiav rau hauv cov khoom tawg
