Lymphocytes nui ake i roto i te toto: take ki te kia elucidated

Ko te pūtau o te pūnaha ārai mate tangata - lymphocytes - no ki te rōpū leukocyte o agranulocytes ma, me te hanga tikanga mo te hanganga o te wātea i te mate humoral me pūtau. wātea i te mate Humoral whakawhanake paturopi me whakarato te pūtau whakapā ki patunga pūtau. mahi hoki lymphocytes rite ngā o te tahi atu pūtau toto, me te whakahaere i o ratou mahi, ki te tika.

Lymphocytes me lymphoblasts

Lymphocytes - Kei te tūtahi i te āhuatanga pūtau o te pūnaha ārai mate katoa i roto i te tinana tangata, e tomo te toto i te hinu wheua wheua, me te ka mahi mātātoa i roto i te kiko lymphoid. Ki te nui haere lymphocytes i te toto, ki te take hoki tenei tono mārama tonu, me hiahia tuatahi hanga he tātaritanga taiwhanga noa. I roto i te pūkete toto lymphocyte hautanga pakeke mō te 20 - 35 ōrau o te tapeke o ngā pūtau ma. Ko etahi o ratou (e pā ana ki 2%) i roto i te tohanga noa i roto i te rere toto piringa, me 98% kei roto i te kopa. E ai ki ona lymphocytes āhuatanga morphological e wehea ki e rua ngā wāhanga: potakataka nui (NK pūtau immunoblast, lymphoblasts) me te iti (T-pūtau me B-pūtau). He mātātoa katoa o enei pūtau, ā, e whai wāhi lymphoblasts i roto i ngā tukanga ārai nui iti. Ki te tirohia e koe i te ihirangi tiketike o lymphocytes i te toto, i te tikanga e kua puta huringa kino o te tinana, i reira ko tetahi puna huna o te mate mumura rohe ranei.

rōpū lymphocyte

pūtau B kitea antigens hanganga manene ongó ki te tinana. I te wa ano hua ratou i te rāpoi ngota pūmua e haamou i āpiha kino. whakangaro T-pūtau antigens te pupuri wātea i te mate i roto i te wāhanga hohe, te ārai tona hono vete '. lymphocytes nui ake i roto i te toto, te take hoki tenei iwi e kore e mohio, e kitea e te whakamātautau toto. NK lymphocytes whakahaere te kounga o te pūtau, puta noa i te tinana. I te wa ano whakangaromia ratou nga pūtau, ngā hanganga ture kāore-, pērā i ngā pūtau mate pukupuku. T lymphocytes kėia 70-80% o te katoa maha o B-pūtau kei roto i te ōwehenga o 15-20%, me NK tino numera iti lymphocytes, e kore te mea to ratou ihirangi neke atu i 5-10%. Ki te nui haere lymphocytes i te toto, kia kia rerekē nga take, engari i roto i tetahi take ko reira he tohu e kore te tinana he tika katoa.

pathogenesis

Lymphocytes tahi me ratou wāhanga rāpoi tauturu i whakatinana te pathogenesis o hē ārai, ngā mate hopuhopu, mate pukupuku, me mate pāwera, papā transplant me, nui atu, he mate autoimmune. I roto i Kia whakanui i mahi te taumata o lymphocytes me ahua lymphocytosis, puta tenei i te whakautu tika ki te mahi antigenic. I roto i te take i reira ko te nui haere te maha o lymphocytes, te auraa te timatanga o te whawhai pūtau ki antigens. Ko taea hoki mai te reira te taumata heke, i roto i te take o te whakautu ta'efe'unga ki whakaongaonga ki antigens me ka reira lymphopenia.

wetewete o lymphocytes

I roto i te mahi haumanu, i reira leukemoid tauhohe momo lymphatic, i roto i nei i reira ko te tauira ki te āhuatanga o te kanisā ma'i whakapeka ranei. He taua tauhohenga i mononucleosis hopuhopu, mate kohi, pakewakewa me brucellosis. mononucleosis hopuhopu - te hua o te mate viral, te nuinga noa puta i roto i ngā tamariki, āhuatanga e te taumata tiketike o te leukocytosis tika ki lymphocytes, i roto i te akoranga o te mate whiwhi huru maitatai hou o te kanorau morphological. Te toto taonga te ki lymphocytes mohiotia, me nga tohu o te dysplasia karihi me piki cytoplasm. I roto i tetahi take, ka pāngia e nui haere lymphocytes i te toto, ka kia tāutuhia, ka whakakorea tae noa ki taea take.
