Cov ntshav ntshav pab li cas nrog kev tiv thaiv tsis zoo ? a) Ntshav ntshav tsim cov tshuaj interferons. e) Ntshav ntshav khi rau kab mob thiab kab mob rau immobilize lawv. * Ntshav ntshav zais cov tshuaj tiv thaiv tshwj xeeb heev.
Ua kom pom qhov no, lub luag haujlwm ntawm ntshav ntshav hauv lub cev tiv thaiv kab mob yog dab tsi?
Ntshav ntshav tsim cov tshuaj tiv thaiv kab mob. Cov tshuaj tiv thaiv kab mob tuaj yeem thaiv cov protein tsim nyog rau khi cov kab mob rau tus tswv tsev, tuaj yeem ua rau cov kab mob sib kis, lossis tuaj yeem ua rau cov kab mob sib xyaw. Cov tshuaj tiv thaiv kab mob tuaj yeem thaiv cov protein tsim nyog rau khi cov kab mob rau tus tswv tsev.
Ib yam li ntawd, cov hlwb twg koom nrog hauv kev tiv thaiv kev dag ntxias? Humoral kev tiv thaiv kuj tseem hu ua kev tiv thaiv kab mob tiv thaiv kab mob. Nrog kev pab los ntawm tus pab T cells, B hlwb yuav sib txawv hauv plasma B hlwb uas tuaj yeem tsim cov tshuaj tiv thaiv tiv thaiv kab mob tshwj xeeb. Kev tso dag tiv thaiv kab mob cuam tshuam nrog antigens los ntawm cov kab mob uas kis tau dawb, lossis sab nraum cov kab mob sib kis.
Ua kom pom qhov no, Plasma cells pab tua kab mob li cas?
Cov lus teb tsis txaus ntseeg yog kho los ntawm cov tshuaj tiv thaiv kab mob molecules uas yog zais los ntawm ntshav ntshav . Rau nkag hlwb , cov kab mob thiab kab mob intracellular khi rau cov molecules tshwj xeeb ntawm lub hom phiaj ntawm tes nto. Antibodies uas khi rau cov kab mob tuaj yeem tiv thaiv qhov no thiab yog hais rau neutralize cov kab mob.
Cov kauj ruam ntawm cov lus teb tsis txaus ntseeg yog dab tsi?
Kauj Ruam 1: Macrophage nkag mus rau tus kab mob. Kauj Ruam 2: Macrophage tom qab zom cov kab mob thiab nthuav tawm cov kab mob antigens. Kauj Ruam 3: T pab tus xovtooj ntawm tes khi rau macrophage thiab dhau los ua tus pabcuam T pabcuam pabcuam. Kauj Ruam 4: Qhib T pabcuam pabcuam txuas rau B cell txhawm rau qhib B cell.

Hom ntshav twg muaj ob qho tshuaj tiv thaiv A thiab tiv thaiv B hauv lawv cov ntshav?
ABO antigens thiab cov tshuaj tiv thaiv Lub npe ntawm Pawg Ntshav Antigens muaj nyob rau ntawm cov xov tooj liab liab ABO cov tshuaj tiv thaiv tam sim no hauv ntshav Hom O nil anti-A thiab anti-B Hom A A antigen anti-B Type B B antigen anti-A Type AB A thiab B antigens nil
Cov kab mob twg xav tau kev tiv thaiv kev tiv thaiv?
Tiv thaiv kev tiv thaiv kev sib cais -siv rau kis kab mob, kab mob, lossis kab mob uas kis los ntawm kev kov tus neeg mob lossis khoom hauv chav (piv txwv: MRSA, VRE, mob raws plab, qhib qhov txhab, RSV). Cov neeg ua haujlwm saib xyuas kev noj qab haus huv yuav tsum: Hnav lub tsho thiab hnab looj tes thaum nyob hauv tus neeg mob chav
Cov tshuaj tiv thaiv kab mob pab tiv thaiv kab mob li cas?
Cov tshuaj tiv thaiv, tseem hu ua immunoglobulins, yog Y-zoo li cov proteins uas tsim los ntawm lub cev tiv thaiv kab mob los pab tiv thaiv cov neeg nkag los ntawm kev ua phem rau lub cev. Thaum pom cov tshuaj antigen hauv lub cev, lub cev tiv thaiv kab mob yuav tsim cov tshuaj tiv thaiv los ua cim antigen rau lub cev kom rhuav tshem
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
Cov hlwb twg koom nrog hauv kev tiv thaiv kev tiv thaiv?
Cov hlwb ntawm lub cev tiv thaiv kab mob yog lymphocytes - B hlwb thiab T hlwb. B hlwb, uas tau muab los ntawm cov leeg pob txha, dhau los ua cov cell uas tsim cov tshuaj tiv thaiv kab mob. T hlwb, uas paub tab hauv thymus, sib txawv rau hauv cov hlwb uas koom nrog hauv lymphocyte maturation, los yog tua cov kab mob uas muaj kab mob
