Lub cev tsis muaj zog repertoire encompasses qhov sib txawv sub-hom kab mob lub cev tiv thaiv kab mob ua rau immunoglobulins los yog T-cell receptors. Cov no pab paub cov kab mob hauv feem ntau cov vertebrates. Xws li ntau yam sib txawv ua rau muaj qhov sib txawv ntawm hom qis uas lees paub ib qho ntawm ntau cov kab mob uas cov kab mob tuaj yeem ntsib.
Ib yam li ntawd, TCR sequencing yog dab tsi?
Tus yam ntxwv T cell receptor repertoires siv kev nkag siab ua ntu zus ( TCR -seq) Kev lees paub ntawm antigens los ntawm T hlwb tso siab rau ntau hom repertoire ntawm T-cell receptor ( TCR ) chains. Peb tsim cov txheej txheem rau kev siv siab nkag ua ntu zus rau daim ntawv qhia TCR repertoires ntawm kev daws teeb meem siab ( TCR - sib).
Ib yam nkaus, B cell repertoire yog dab tsi? B hlwb yog ib qho tseem ceeb nyob rau hauv pathogenesis ntawm ntau yam, thiab tej zaum tag nrho, cov kab mob tiv thaiv kab mob. Txhua B cev qhia ib leeg B cev Tus neeg txais khoom (BCR)1, thiab ntau yam ntawm BCRs qhia los ntawm tag nrho B cev Cov pej xeem ntawm ib tus neeg raug hu ua 'BCR repertoire '.
Xav txog qhov no, ntsuas TCR li cas?
Cov txoj kev ntsuas TCR yog tus qauv hauv MIL-STD-202 Txoj Kev 304. Nrog rau txoj kev no, TCR yog xam rau thaj tsam ntawm -55 ° C thiab 25 ° C thiab nruab nrab ntawm 25 ° C thiab 125 ° C. Vim tias siab tshaj ntsuas tus nqi yog txhais raws li TCR , txoj kev no feem ntau tshwm sim nyob rau hauv tshaj qhia ib tug resistor rau tsawg thov thov.
T cell receptors lees paub dab tsi?
Cov T - cell receptor (TCR) yog cov qauv pom nyob rau saum npoo av T hlwb , los yog T lymphocytes , uas yog lub luag haujlwm rau paub txog fragments ntawm antigen li peptides khi rau loj histocompatibility complex (MHC) molecules.
