Lymphocytes . Lymphocytes yog lwm hom ntshav dawb. Lawv paub cov proteins ntawm qhov chaw kab mob hu ua antigens. Yog lawv ua , lawv clone lawv tus kheej thiaj li ua txaus cov tshuaj tiv thaiv rhuav tshem cov kab mob.
Hais txog qhov no, ua li cas lymphocytes thiab phagocytes rhuav tshem cov kab mob?
Lawv rhuav tshem cov kab mob los ntawm phagocytosis . Qhov sib txawv tseem ceeb ntawm lymphocytes thiab phagocytes yog tias cov lymphocytes tsim cov lus teb tiv thaiv tshwj xeeb tiv thaiv kab mob hos phagocytes tsim tib cov lus teb rau ib qho kab mob.
Tsis tas li ntawd, cov qe ntshav dawb ua kom cov kab mob puas tsuaj? Cov qe ntshav dawb ua haujlwm hauv ob txoj kev; lawv tuaj yeem noj tau lossis nqus tau kab mob thiab rhuav tshem lawv los ntawm kev zom lawv. Cov qe ntshav dawb kuj tuaj yeem tsim cov tshuaj tiv thaiv kab mob rau rhuav tshem tshwj xeeb kab mob los ntawm clumping lawv ua ke thiab rhuav tshem lawv. Lawv kuj tsim cov tshuaj antitoxins uas tawm tsam cov co toxins uas tso tawm los ntawm kab mob.
Ib sab saum toj no, cov tshuaj tiv thaiv kab mob ua kom puas tus kab mob li cas?
Antigens yog cov proteins uas muaj nyob rau ntawm qhov chaw ntawm lub cev kab mob . Cov cov tshuaj tiv thaiv ua kom puas antigen ( kab mob ) uas yog ces engulfed thiab digested los ntawm macrophages. Cov qe ntshav dawb tuaj yeem tsim cov tshuaj hu ua antitoxins uas rhuav tshem cov co toxins (poisons) qee cov kab mob tsim thaum lawv tau nkag mus rau hauv lub cev.
Cov lymphocytes tiv thaiv kab mob li cas?
Ib hom tshwj xeeb ntawm cov lymphocyte hu ua nco lymphocyte tau 'nco ntsoov' antigens los ntawm ib qho kab mob los ntawm tus kab mob yav dhau los. Qhov thib ob raug rau tib yam kab mob ua rau cov qe ntshav dawb rau teb sai sai rau tsim ntau cov tshuaj tiv thaiv cuam tshuam, uas tiv thaiv kab mob.

Txoj kev kho mob qog noj ntshav twg siv cov phiaj tsom ntawm lub zog ionizing txhawm rau rhuav tshem cov hlwb phem?
Kev kho hluav taws xob lossis kho hluav taws xob, feem ntau sau luv RT, RTx, lossis XRT, yog kev kho mob siv hluav taws xob ionizing, feem ntau yog ib feem ntawm kev kho mob qog noj ntshav kom tswj lossis tua cov kab mob phem thiab nquag xa los ntawm cov kab nrawm
Hom kev tiv thaiv twg siv T cells los rhuav tshem cov kab mob hauv lub cell?
Hauv cov xwm txheej no, lub cev tiv thaiv kab mob siv kev tiv thaiv kab mob ntawm tes los rhuav tshem cov kab mob hauv lub cev. T cells yog lub luag haujlwm rau kev tiv thaiv kab mob hauv nruab nrab ntawm tes. Killer T cells (cytotoxic T cells) pab tshem tawm cov kab mob hauv lub cev los ntawm kev tso cov co toxins rau hauv lawv thiab txhawb apoptosis
Tib neeg cov qe ntshav dawb pab rhuav tshem cov kab mob pathogenic li cas?
Cov qe ntshav dawb ua haujlwm ob txoj hauv kev; lawv tuaj yeem noj lossis nkag mus rau cov kab mob thiab rhuav tshem lawv los ntawm kev zom lawv. Cov qe ntshav dawb tseem tuaj yeem tsim cov tshuaj tiv thaiv los rhuav tshem cov kab mob tshwj xeeb los ntawm kev sib sau ua ke thiab rhuav tshem lawv. Lawv kuj tsim cov tshuaj antitoxins uas tiv thaiv cov co toxins tawm los ntawm cov kab mob
Vim li cas cov hlwb hauv MM Tumors raug rhuav tshem los ntawm kev tiv thaiv kab mob?
MM yog tshwm sim los ntawm qhov ua tsis tau zoo ntawm cov protein nyob hauv cov cell ntawm daim nyias nyias. Cov cell hauv MM qog tuaj yeem raug rhuav tshem los ntawm kev tiv thaiv kab mob
