Phagocytes yog pob txha pob txha-derived hlwb ntawm myeloid keeb kwm, suav nrog neutrophils, eosinophils, basophils, monocytes, thiab daim ntawv loj hlob ntawm cov monocyte.
phagocytes nyob qhov twg?
Phagocytes thiab Lawv Receptors
Phagocytes suav nrog neutrophils, macrophages, thiab dendritic cells (DCs), uas muaj peev xwm engulf thiab zom cov khoom loj ntawm qhov kev txiav txim ntawm 1-10 µm thiab loj dua. Hauv cov neeg laus, cov hlwb no yog tsim los ntawm hematopoietic qia hlwb hauv cov pob txha.
Cov hlwb twg tsim phagocytes?
Hauv cov ntshav, ob hom qe ntshav dawb, neutropphilic leukocytes (microphages) thiab monocytes (macrophages), yog phagocytic. Neutrophils yog me me, granular leukocytes uas tshwm sim sai sai ntawm qhov chaw ntawm qhov txhab thiab noj cov kab mob.
Cov qe ntshav dawb twg yog phagocytes?
Nyob rau hauv tib neeg, thiab nyob rau hauv vertebrates feem ntau, cov phagocytic hlwb uas zoo tshaj plaws yog ob hom qe ntshav dawb: lub macrophages (cov phagocytic loj) thiab cov neutrophils (ib hom. ntawm granulocytes).
Dab tsi nyiam phagocytes rau thaj tsam?
Thaum muaj tus kab mob tshwm sim, tshuaj "SOS" teeb liabraug muab tawm los nyiam phagocytes rau ntawm qhov chaw. Cov cim tshuaj lom neeg no yuav suav nrog cov proteins los ntawm cov kab mob nkag mus, cov kab mob plab peptides, ntxiv cov khoom, thiab cytokines uas tau muab tawm los ntawm macrophages nyob rau hauv cov ntaub so ntswg ze ntawm qhov chaw kis kab mob.
