Peb puas yuav kawm txog lub kaw lus zais cia (opsonization) uas ntes tau cov yeeb ncuab ntawm lub cev?

Koj puas tau xav txog seb muaj kev sib ntaus sib tua ntau npaum li cas hauv peb lub cev txhua lub sijhawm? Cov kab mob los ntawm sab nraud, cov kab mob xws li cov kab mob me me, cov hlwb mob qog noj ntshav uas loj hlob hauv lub cev, lossis peb cov hlwb uas laus thiab tuag ... Peb txhua tus muaj lub cev tiv thaiv loj los tiv thaiv peb lub cev ntawm txhua yam no. Peb hu qhov no ua lub cev tiv thaiv kab mob. Nws zoo li ib pab tub rog uas tiv thaiv peb lub tebchaws. Tab sis pab tub rog no paub li cas tias leej twg yog yeeb ncuab thiab leej twg yog phooj ywg? Hnub no peb yuav tham txog ib qho txheej txheem zoo kawg nkaus, nyuaj me ntsis, tab sis tseem ceeb heev uas pab nrog qhov ntawd.

Opsonization yog dab tsi? Cia peb nkag siab yooj yim.

Lo lus no tej zaum yuav zoo li nyuaj me ntsis, tab sis lub ntsiab lus yooj yim heev. Opsonization, hais yooj yim xwb, yog tus txheej txheem uas peb lub cev tiv thaiv kab mob "cim" thiab ntes cov khoom uas ua rau peb puas tsuaj, xws li cov kab mob lossis cov hlwb puas.

Xav txog qhov no. Ib tug tub sab tau khiav dim thiab nkaum hauv koj lub tsev. Tub ceev xwm tuaj nrhiav nws, tab sis nws nyuaj rau nrhiav nws. Tab sis yog tias muaj ib tug neeg tuaj thiab muab daim nplaum ci ntsa iab rau ntawm tus tub sab cov khaub ncaws? Ces tub ceev xwm tuaj yeem txheeb xyuas thiab ntes tus tub sab txawm tias nyob hauv qhov tsaus ntuj. Qhov ntawd yog qhov tshwm sim nrog cov txheej txheem no hu ua opsonization. Ib hom protein tshwj xeeb lo rau cov kab mob thiab cov hlwb tsis xav tau uas peb lub cev tiv thaiv cov hlwb tsis tuaj yeem paub yooj yim. Ib yam li daim nplaum ci ntsa iab ntawd. Ces peb cov hlwb tiv thaiv tuaj thiab pom cov khoom "cim" no, ntes lawv thiab rhuav tshem lawv.

Lo lus no yog los ntawm lo lus Greek uas txhais tau tias "ua kom qab." Ib yam li peb ua kom zaub mov qab thiab xav noj, cov txheej txheem no cim peb cov hlwb tiv thaiv kab mob hauv txoj kev uas ua rau lawv xav "noj" cov kab mob.

Yog li cov "cim" hu ua Opsonins yog leej twg?

Koj puas nco qab cov "ntawv nplaum ci ntsa iab" uas peb tau tham txog ua ntej lawm? Cov ntawv nplaum ntawd yog yam peb hu ua opsonins hauv kev kho mob. Cov no yog cov protein tshwj xeeb uas ntab tau yooj yim hauv peb cov ntshav thiab cov lymphatic system. Thaum lub cev tiv thaiv kab mob ua haujlwm, lawv yuav ua haujlwm thiab lo rau ntawm qhov chaw ntawm cov kab mob lossis cov cell tsis xav tau.

Cov opsonins no kuj hu ua "bridging molecules" vim tias lawv ua ib lub choj ntawm cov kab mob thiab lub cell tiv thaiv kab mob uas tuaj rhuav tshem nws. Lub choj no tso cai rau lub cell tiv thaiv kab mob kom yooj yim ntes thiab nqos cov kab mob.

Lo lus loj Phagocytosis txhais li cas?

Phagocytosis yog lo lus siv los piav txog "kev nqos thiab kev rhuav tshem ib yam dab tsi los ntawm cov cell." Hais yooj yim xwb, nws yog "cellular engulfment." Qee cov cell tiv thaiv hauv peb lub cev, zoo li cov tsheb thauj khib nyiab, nqos, noj, zom, thiab rhuav tshem cov khoom tsis xav tau. Peb hu cov cell "nqos" no.Hu ua phagocytes.
