Microglial cells yog cov neeg tshwj xeeb ntawm macrophages uas pom muaj nyob hauv lub hauv nruab nrab paj hlwb (CNS). Lawv tshem tawm cov neurons puas thiab kis kab mob thiab tseem ceeb rau kev saib xyuas kev noj qab haus huv ntawm CNS.
Kev ua haujlwm ntawm microglia yog dab tsi?
Microglia cells yog cov kab mob tiv thaiv kab mob hauv nruab nrab ntawm lub paj hlwb thiab yog li ua lub luag haujlwm tseem ceeb hauv mob hlwb thiab mob Tsis ntev los no hauv vivo cov duab kev tshawb fawb tau qhia tias nyob rau hauv lub hlwb noj qab haus huv, microglia yog qhov muaj zog heev, txav mus tas li los tshawb xyuas lub hlwb parenchyma.
microglia hauv hlwb yog dab tsi?
Microglial cells yog cov tshuaj tiv thaiv kab mob tseem ceeb tshaj plaws ntawm lub hauv paus paj hlwb (CNS) thiab yog thawj zaug teb thaum muaj qee yam tsis zoo hauv lub hlwb [1]. Cov pejxeem microglial suav txog kwv yees li 10% ntawm cov hlwb hauv tag nrho lub hlwb [2].
microglia yog dab tsi thiab lawv lub hauv paus thiab kev ua haujlwm yog dab tsi?
Cov hlwb glial yog cov hlwb tsiv teb tsaws chaw hauv lub paj hlwb, ua thawj kab ntawm kev tiv thaiv kab mob hauv nruab nrab paj hlwb. Cov microglia zoo li macrophages engulfing txawv teb chaws cov ntaub ntawv Los ntawm cov txheej txheem ntawm phagocytosis, microglia tshem tawm cov neurons thiab cellular khib nyiab.
Puas muaj pes tsawg microglia hauv lub hlwb?
Microglial hlwb muaj nyob rau hauv cov lej zoo sib xws rau cov neurons, sawv cev ib ncig ntawm 10-20% ntawm tag nrho cov hlwb glial thiab suav txij li 100 txog 200 billion hlwb nyob ntawm tus mob (piv txwv li, noj qab nyob zoo, muaj kab mob, muaj kab mob).
