Cov humoral tiv thaiv kab mob yog kho nruab nrab los ntawm cov tshuaj tiv thaiv kab mob molecules uas zais los ntawm cov ntshav ntshav. Txhawm rau nkag mus rau cov cell, cov kab mob thiab cov kab mob intracellular khi rau cov molecules tshwj xeeb ntawm lub hom phiaj ntawm tes. Cov tshuaj tiv thaiv kab mob uas khi rau cov kab mob tuaj yeem tiv thaiv qhov no thiab tau hais kom tshem tawm cov kab mob.
Hauv txoj kev no, kev tiv thaiv kev lim hiam ua dab tsi?
Humoral kev tiv thaiv kuj tseem hu ua kev tiv thaiv kab mob tiv thaiv kab mob. Nrog kev pab los ntawm tus pab cuam T cells, B cells yuav sib txawv ua ntshav plasma B uas tuaj yeem tsim tau tshuaj tiv thaiv tiv thaiv ib qho antigen tshwj xeeb. Lub cev tiv thaiv kab mob humoral cuam tshuam nrog cov tshuaj tiv thaiv kab mob los ntawm cov kab mob uas tawm mus dawb, lossis sab nraum cov kab mob.
Ib yam nkaus, dab tsi yog cov kauj ruam ntawm cov lus teb tsis txaus ntseeg? Kauj ruam 1: macrophage nkag mus rau tus kab mob. Kauj ruam 2: Cov macrophage ces zom cov kab mob thiab nthuav tawm cov kab mob antigens. Kauj ruam 3: T pab tus xovtooj khi rau macrophage thiab dhau los ua tus pabcuam T pabcuam pabcuam. Kauj ruam 4: Lub tshuab ua haujlwm T pab cell khi rau B cell txhawm rau qhib B cell.
Tsis tas li kom paub yog, dab tsi yog qhov piv txwv ntawm kev tiv thaiv kev dag ntxias?
Innate kev tiv thaiv kuj tseem tuaj hauv cov tshuaj muaj protein ntau, hu ua innate humoral 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). Passive kev tiv thaiv yog vim muaj cov tshuaj tiv thaiv uas tsim tawm hauv lub cev uas tsis yog koj tus kheej.
Qhov kev lom zem tsis zoo tshwm sim nyob qhov twg?
Nyob ntawm seb hom kev tawm tsam txawv teb chaws, ob qhov sib txawv tiv thaiv kab mob lus teb tshwm sim : Cov humoral teb (lossis tshuaj tiv thaiv kab mob sib kis lus teb ) cuam tshuam nrog B hlwb uas paub txog antigens lossis kab mob uas tau nthuav tawm hauv cov qog ntshav lossis ntshav ("lom zem" yog lub sijhawm nruab nrab rau lub cev kua).
Pom zoo:
Yuav tiv thaiv kev tiv thaiv tus kheej li cas?
Passive Immunity. Kev tiv thaiv tsis zoo tuaj yeem tshwm sim ib txwm muaj, xws li thaum tus menyuam mos tau txais niam cov tshuaj tiv thaiv los ntawm lub tsho me nyuam lossis niam mis, lossis dag, xws li thaum tus neeg tau txais cov tshuaj tiv thaiv kab mob hauv kev txhaj tshuaj (txhaj tshuaj gamma globulin)
Cell tiv thaiv kev tiv thaiv kab mob ua haujlwm li cas?
Cell-mediated immunity (CMI) yog kev tiv thaiv kab mob uas tsis koom nrog cov tshuaj tiv thaiv tab sis ntau ntxiv nrog kev ua kom macrophages thiab NK-cells, tsim cov antigen-specific cytotoxic T-lymphocytes, thiab tso tawm ntau yam cytokines hauv kev teb rau antigen
Cell tiv thaiv kev tiv thaiv kab mob txhais tau li cas?
Los ntawm Wikipedia, phau ntawv txhais lus pub dawb. Kev tiv thaiv kab mob ntawm tes yog kev tiv thaiv kab mob uas tsis koom nrog cov tshuaj tiv thaiv kab mob. Qhov tseeb, kev tiv thaiv kab mob hauv nruab nrab ntawm tes yog ua kom muaj phagocytes, antigen-specific cytotoxic T-lymphocytes, thiab tso tawm ntau yam cytokines hauv kev teb rau antigen
Cov kev tiv thaiv tsis tshwj xeeb tiv thaiv lub cev li cas?
Lub cev tsis muaj zog tiv thaiv kab mob no tsis muaj kev tiv thaiv tshwj xeeb los ntawm cov txheej txheem tiv thaiv, uas suav nrog cov teeb meem ntawm lub cev xws li tawv nqaij, teeb meem tshuaj lom neeg xws li cov tshuaj tua kab mob tua kab mob uas tsim kev puas tsuaj los yog rhuav tshem cov neeg tuaj txawv teb chaws, thiab cov cell uas tawm tsam cov cell txawv teb chaws thiab lub cev lub cev muaj cov kab mob sib kis
Cov tshuaj tiv thaiv ua haujlwm li cas lawv ua haujlwm tiv thaiv kab mob thiab kab mob?
Cov tshuaj tiv thaiv ua haujlwm los ntawm kev cob qhia lub cev tiv thaiv kab mob kom paub thiab tawm tsam cov kab mob, xws li kab mob lossis kab mob. Txhawm rau ua qhov no, qee cov molecules los ntawm cov kab mob yuav tsum tau nkag rau hauv lub cev kom ua rau muaj kev tiv thaiv kab mob. Cov molecules no hu ua antigens, thiab lawv muaj nyob rau tag nrho cov kab mob thiab cov kab mob
