Ilya Metchnikoff nrhiav pom phagocytosis (ib daim ntawv ntawm endocytosis uas siv vesicles rau internalize cov khoom). Phagocytes yog cov hlwb tshwj xeeb uas noj thiab rhuav tshem cov kab mob.
Leej twg pom phagocytosis?
Ib lub teeb pom kev zoo li no yog Elie Metchnikoff, tus kws tshawb fawb Lavxias uas yog thawj zaug pom phagocytosis, cell-mediated immune teb rau txawv teb chaws. Ua ntej nws qhov kev tshawb pom, cov qe ntshav dawb, piv txwv li, tau xav tias yuav coj cov kab mob kom tsis txhob tua kab mob, tab sis kom kis tau.
Thaum twg phagocytosis nrhiav tau?
Phagocytosis tau tshawb pom los ntawm Elie Metchnikoff (Ilia Mechnikov) hauv 1882.
Leej twg nrhiav tau tus txheej txheem ntawm phagocytosis hauv cellular tiv thaiv?
Élie Metchnikoff (1845–1916) tau ua nws qhov kev soj ntsuam thawj zaug hauv 1880s thaum kawm txog cov kab mob tsis muaj zog hauv hiav txwv. Nws pom cov hlwb tshwj xeeb tua cov pos me me tso rau hauv cov ntses hnub qub. Raws li cov kev tshawb pom no, tom qab ntawd nws tau tsiv mus rau hauv kev tiv thaiv kab mob thiab tau sib tw lub tswv yim ntawm kev tiv thaiv ntawm tes.
Dab tsi ua rau phagocytosis?
Cov txheej txheem ntawm phagocytosis pib nrog kev khi ntawm opsonins (piv txwv li ntxiv lossis tshuaj tiv thaiv kab mob) thiab / lossis cov molecules tshwj xeeb ntawm cov kab mob saum npoo(hu ua kab mob sib txuas nrog cov kab mob [PAMPs]) rau cell nto receptors ntawm phagocyte. Qhov no ua rau receptor clustering thiab ua rau phagocytosis.
