Ntxiv rau cov poov xab thiab cov qog ntshav, nco B hlwb muaj nyob hauv pob txha pob txha, Peyers ' thaj ua rau thaj, gingiva, mucosal epithelium ntawm tonsils, lamina propria ntawm lub plab hnyuv, thiab nyob rau hauv txoj kev (67, 71–76).
nco B hlwb tuaj qhov twg?
Cov hlwb tshwm sim los ntawm T-cell nyob ntawm cov tshuaj tiv thaiv hauv lub chaw kab mobthiab yog hom cell tseem ceeb rau kev tiv thaiv kab mob kom rov sib tw los ntawm antigen. Txawm hais tias, zoo li plasma hlwb, nco B hlwb sib txawv ntawm GC cov tshuaj tiv thaiv, lawv tsis tso cov tshuaj tiv thaiv kab mob thiab tuaj yeem ua rau nws tus kheej ntawm antigen [85].
nco lymphocytes nyob qhov twg?
Central nco T hlwb tshwm sim hauv cov qog ntshav hauv nruab nrab, feem ntau hauv cov qog thiab cov tonsils, nrog cov molecules hauv qab no ntawm lawv qhov chaw: CD45RO, CCR7, CD62L, CD44, CD27, CD28, CD95, CD122 [5, 7, 8] thiab LFA-1 (CD11a/CD18) molecules interacting with APCs [9].
Lub hlwb puas tsim tau?
Nco B hlwb yog B cell sub-hom uas tau tsim ua raws tus kab mob thawj zaugTom qab thawj zaug (thawj teb) tus kab mob cuam tshuam nrog qee yam antigen, cov lus teb. naïve hlwb (cov uas tsis tau raug cov antigen) proliferate los tsim ib tug colony ntawm hlwb.
Thaum twg lub cim xeeb B hlwb tsim?
Nco B hlwb raug tsim los teb rau T-dependent antigens, thaum lub sij hawm GC cov tshuaj tiv thaiv, nyob rau hauv parallel mus rau plasma hlwb (Fig. 2-5). Thaum lawv tawm ntawm GCs, nco B hlwb tau txais cov khoom tsiv teb tsaws mus rau thaj chaw extrafollicular ntawm tus po thiab cov nodes.

Malloc faib lub cim xeeb nyob qhov twg?
Ib txwm, malloc faib lub cim xeeb los ntawm lub heap, thiab kho qhov loj ntawm heap raws li xav tau, siv sbrk(2). Thaum faib cov blocks ntawm lub cim xeeb loj dua MMAP_THRESHOLD bytes, qhov kev siv glibc malloc faib lub cim xeeb raws li tus kheej tsis qhia npe siv mmap(2) .
Catarrh khaws cia hauv lub cev nyob qhov twg?
Catarrh yog ib qho exudate ntawm qhov mob mucous daim nyias nyias nyob rau hauv ib qho ntawm cov hlab cua los yog kab noj hniav ntawm lub cev, feem ntau yog hais txog caj pas thiab paranasal sinuses. Nws tuaj yeem ua rau cov kua qaub tuab thiab cov qe ntshav dawb tshwm sim los ntawm o ntawm cov mucous daim nyias nyias nyob rau hauv lub taub hau teb rau tus kab mob .
Cov hlau khaws cia hauv lub cev nyob qhov twg?
Feem ntau ntawm koj lub cev hlau yog nyob rau hauv hemoglobin ntawm koj cov qe ntshav liab, uas nqa oxygen rau koj lub cev. Cov hlau ntxiv yog khaws cia rau hauv koj daim siab thiab siv los ntawm koj lub cev thaum koj noj zaub mov tsawg dhau .

Leej twg yog khaws cia cia?
Corpses raug rau cov txheej txheem cryonics suav nrog cov neeg ntaus pob ntaus pob Ted Williams thiab tus tub John Henry Williams (hauv 2002 thiab 2004, raws li), engineer thiab kws kho mob L. Stephen Coles (Xyoo 2014), tus kws tshaj lij nyiaj txiag thiab tus kws ua lag luam Phil Salin, thiab software engineer Hal Finney (hauv 2014) .
