Cheebtsam ntawm lub cev tiv thaiv kab mob innate. Lub cev tiv thaiv kab mob suav nrog suav nrog cov teeb meem ntawm lub cev thiab lub cev nrog rau kev ua haujlwm ntawm cov cell, cov tshuaj tiv thaiv kab mob peptides, cov tshuaj nruab nrab daws, thiab ntawm tes receptors (Table 1). Cov tawv nqaij thiab mucosa muab kev tiv thaiv kab mob zoo ntawm sab hauv thiab sab nraud ib puag ncig.
Kuj paub, dab tsi yog lub cev tiv thaiv kab mob los ntawm lub cev?
Tsis muaj kev tiv thaiv hais txog cov txheej txheem tiv thaiv tshwj xeeb uas tuaj rau hauv kev ua si tam sim lossis hauv ob peb teev ntawm cov tshuaj tiv thaiv kab mob hauv lub cev. Cov txheej txheem no suav nrog teeb meem lub cev xws li tawv nqaij, tshuaj lom neeg hauv ntshav, thiab tiv thaiv kab mob cov cell uas tawm tsam cov cell txawv hauv lub cev.
Tsis tas li ntawd, dab tsi yog kev tiv thaiv ib txwm muaj thiab piv txwv? Tsis muaj kev tiv thaiv kuj tseem tuaj hauv cov tshuaj muaj protein ntau, hu ua innate tso dag tso luag kev tiv thaiv . Piv txwv suav nrog lub cev ua kom tiav thiab cov tshuaj hu ua interferon thiab interleukin-1 (uas ua rau kub cev). Tsis muaj zog serum globulin (muab rau kis kab mob siab) thiab tetanus antitoxin yog piv txwv ntawm kev txhaj tshuaj tiv thaiv kab mob.
Ib yam nkaus, puas yog B hlwb ib feem ntawm lub cev tsis muaj zog?
Ntshav dawb hlwb ua lub luag haujlwm tseem ceeb hauv ob qho tib si innate thiab yoog raws tiv thaiv kab mob lus teb Kev yoog raws kev tiv thaiv kab mob yog kho kom haum xeeb los ntawm lub cev tiv thaiv kab mob hu ua cov lymphocytes . Cov no yog B thiab T. hlwb . B hlwb zais cov tshuaj tiv thaiv, tshwj xeeb tshaj yog cov protein molecules uas khi rau cov kab mob tshwj xeeb.
Puas yog interferons yog ib feem ntawm lub cev tiv thaiv kab mob?
Cov tshuaj interferons . Cov tshuaj interferons , lossis IFNs, yog cov protein uas tau tsim thiab tso tawm hauv lus teb rau cov kab mob xws li kab mob, kab mob, cab thiab kab mob qog noj ntshav. Cov tshuaj interferons ua lub luag haujlwm tseem ceeb ua thawj kab ntawm kev tiv thaiv kab mob. IFNs yog ib feem ntawm qhov tsis tshwj xeeb tiv thaiv kab mob.
