Paratope yog ib feem ntawm ib qho tshuaj tiv thaiv uas lees paub ib antigen , cov antigen - khi site ib tshuaj tiv thaiv . Nws yog thaj av me me (15-22 amino acids) ntawm antibody cov Fv cheeb tsam thiab muaj ib feem ntawm antibody cov hnyav thiab lub teeb saw. Ib feem ntawm qhov antigen qhov uas paratope khi hu ua epitope.
Ntxiv mus, puas antigens khi rau cov tshuaj tiv thaiv?
Muaj ob peb hom tshuaj tiv thaiv thiab antigens , thiab cwb tshuaj tiv thaiv muaj peev xwm ntawm khi tsuas yog rau qhov tshwj xeeb antigen . Antigens raug khi rau tshuaj tiv thaiv los ntawm kev qaug zog thiab tsis muaj kev cuam tshuam xws li kev sib cuam tshuam hluav taws xob, kev sib txuas hydrogen, Van der Waals rog, thiab kev sib cuam tshuam hydrophobic.
Ib tus kuj yuav nug, cov tshuaj tiv thaiv kab mob yog dab tsi thiab lawv cuam tshuam nrog antigens li cas? Cov tshuaj tiv thaiv (immunoglobins) yog cov protein zoo li Y tsim los ntawm B cells ntawm lub cev tiv thaiv kab mob los teb rau kis antigens . Txhua tshuaj tiv thaiv muaj ib qho paratope uas paub txog ib qho epitope ntawm ib qho antigen , ua yeeb yam zoo li lub xauv thiab qhov tseem ceeb khi txoj haujlwm.
Ib yam li ntawd, koj tuaj yeem nug, yuav ua li cas tom qab cov tshuaj tiv thaiv kab mob khi rau antigens?
Thaum twg qee yam tshuaj tiv thaiv ua ke nrog antigens , lawv qhib qhov cascade ntawm cuaj cov protein, hu ua kev sib ntxiv, uas tau nthuav dav hauv daim ntawv tsis ua haujlwm hauv cov ntshav. Ua tiav daim ntawv koom tes nrog tshuaj tiv thaiv , ib zaug lawv tau teb nrog antigen , los pab rhuav tshem cov neeg tawm tsam txawv teb chaws thiab tshem tawm ntawm lub cev.
Muaj pes tsawg antigens tuaj yeem khi cov tshuaj tiv thaiv kab mob?
Txij li thaum ib tshuaj tiv thaiv muaj tsawg kawg yog ob lub paratopes, nws tuaj yeem khi ntau tshaj ib tug antigen los ntawm khi cov epitopes zoo ib yam nqa ntawm qhov chaw ntawm cov no antigens . Los ntawm txheej txheej kab mob, tshuaj tiv thaiv txhawb nqa effector ua haujlwm tawm tsam cov kab mob hauv cov hlwb uas paub txog lawv cheeb tsam Fc.

Qhov twg ntawm cov tshuaj tiv thaiv hauv qab no yog siv rau kev txhaj tshuaj tiv thaiv kab mob?
Passive Immunization DISEASE NAME OF MATERIAL Cytomegalovirus Cytomegalovirus immun globulin, txhaj tshuaj tiv thaiv kab mob Diphtheria Diphtheria antitoxin, equine Rabies Rabies tiv thaiv globulin, tib neeg Measles Immune globulin, tib neeg
Thaum ntsuas kub li cas IgM cov tshuaj tiv thaiv tshuaj tiv thaiv?
Qhov kub zoo tshaj plaws nyob ntawm hom tshuaj tiv thaiv kab mob koom nrog. IgG cov tshuaj tiv thaiv zoo tshaj plaws ntawm 37oC; IgM hnov zoo tshaj plaws ntawm 4oC
Cov ntsiav tshuaj daim ntawv twg muaj cov txheej tshwj xeeb uas tiv thaiv lub plab acid thiab ua rau cov tshuaj yaj hauv cov hnyuv?
Cov txheej txheej enteric yog cov txheej txheem polymer siv rau ntawm cov tshuaj hauv qhov ncauj uas tiv thaiv nws txoj kev tawg lossis tsis tawg hauv ib puag ncig lub plab
Vim li cas cov tshuaj tiv thaiv kab mob khi rau cov antigens tshwj xeeb?
Cov tshuaj tiv thaiv kab mob lees paub qhov tshwj xeeb ntawm lub hom phiaj txawv teb chaws, hu ua antigen. Txhua lub ntsiab lus ntawm "Y" ntawm ib qho tshuaj tiv thaiv muaj ib qho paratope uas yog tshwj xeeb rau ib qho epitope (analogous rau lub xauv thiab qhov tseem ceeb) ntawm ib qho antigen, tso cai rau ob lub qauv no los khi ua ke nrog qhov tseeb
Dab tsi yog cov tshuaj tiv thaiv thiab lawv cuam tshuam nrog cov tshuaj tiv thaiv li cas?
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. Txhua cov tshuaj tiv thaiv muaj ib qho paratope uas paub txog ib qho epitope ntawm ib qho antigen, ua zoo li lub xauv thiab qhov tseem ceeb binding mechanism
