Li-lymphocyte tsa hau li bohlokoa haholo. Mona ke kamoo ba u sireletsang kateng
Lymphocyte ke sele e nyenyane ea mali e nang le karolo e kholo ea ho sireletsa 'mele oa hao ho mafu.
Li-lymphocyte li loantša tšoaetso ka ho hlahisa li-antibodies, tse leng lik'hemik'hale tse thusang ho emisa ebe li tlosa bahlaseli ba tsoang linaheng tse ling tse kang libaktheria, livaerase, li-fungus, likokoana-hloko le lik'hemik'hale tse chefo. Lymphocyte e boetse e bolaea lisele tse 'meleng oa hao tse nang le tšoaetso ea pathogen, le ho lokolla lik'hemik'hale ho lemosa lisele tse ling tsa kotsi.
Le hoja ho na le bopaki bo bong ba hore mofuta o mong oa li-lymphocyte o ka hlasela le ho senya moemeli ea tšoaetsanoang ka kotloloho, boholo ba lymphocytes e tlohela mosebetsi ona ho mefuta e meng ea lisele tse tšoeu tsa mali, ho akarelletsa le phagocytes. (Phagocytes e sebetsa ka ho hlile e metsa le e amohelang bahlaseli bao 'mele oa hau o o nkang e le kotsi, joalo ka libaktheria le likaroloana tse nyenyane.)
Li-lymphocyte, hajoale, li pota-potile 'mele oa hau ka tsamaiso ea lymphatic, e leng karolo ea tsamaiso ea potoloho. Lijana tsa lymph li na le metsi a hloekileng, ho kenyelletsa lymphocytes le lisele tse ling tse tšoeu tsa mali, 'meleng oa hao ho loantša tšoaetso.
Ho na le mefuta e 'meli e meholo ea lymphocyte: Lisele le lisele tsa B. E mong le e mong o na le karolo e khethehileng eo ae phethang bophelong ba hau. Bala ho ithuta ho eketsehileng ka bona.
Li-Cell Lymphocyte tsa T ke Eng?
Mosebetsi oa li-cell lymphocyte ke ho hlahloba le ho hlahloba lisele tsa hau bakeng sa tšoaetso le kotsi ea tšoaetso. Ha libaka tsa lymphocyte e le sele e tšoaelitsoeng ke baktheria kapa kokoana-hloko, lymphocyte e tla tsoela pele ho bolaea sele ('me e tla hopola moemeli ea tšoaetsanoang, kahoo e ka sebetsa ka potlako nakong e tlang ha e kopana le bothata bo tšoaetsanoang bo tšoanang).
Li-lymphocyte tsena tsa T li boetse li bolaea lisele tsa kankere, ke ka lebaka leo tšebetso e 'ngoe e tšepisang ea phekolo ea kankere e akarelletsa ho itšehla thajana, ho ata le ho sebelisa lisele tsa T tsa mokuli ho loantša kankere e itseng. Ho phaella moo, ho na le bopaki ba hore lisele tsa lymphocyte tsa T le tsona li ka u sireletsa ho tsoa libaktheria ka ho kenya likokoana-hloko le ho li bolaea.
T "T" ka seleng ea T e bolela sefate sa thymus, lesela le lenyenyane sefubeng sa hao moo li-T tse ling li eang ho ba boemong bo botle ka mor'a hore li entsoe ka marotholi a hao, le pele li romeloa ho ea patelong ea 'mele oa hao.
B-Cell Lymphocyte ke Eng?
L cell lymphocyte ha li hlasele le ho bolaea lisele, likokoana-hloko kapa libaktheria ka bobona. Ho e-na le hoo, li etsa liprotheine tse bitsoang li-antibodies tse hlileng li khomarelang bahlaseli, li thibela bahlaselli le ho li bonahatsa ho hloekisa likarolo tse ling tsa tsamaiso ea hau ea 'mele ea ho itšireletsa mafung.
Le hoja sele e 'ngoe le e' ngoe e hlahisa motho e mong le e mong ea antibody, palo e kholo ea 'mele oa' mele oa hau e na le palo e ngata e se nang moeli 'me e hlahisa li-antibodies tse ngata ho li loantša.
Joaloka li-cell lymphocyte tsa T, li-cell lymphocyte li boetse li entsoe mothapong oa hao. Ba hōlile ka botoneng ba hao.
Ke'ng e ka Etsang Phoso ka Lymphocyte?
Hangata li-lymphocyte ha li itšoare ka lithahasello tsa hau.
Ka lefu la boipheliso , ka mohlala, lisele tsa lymphocyte tsa T li hlasela likokoana-hloko tsa hao ka phoso, li etsa hore lisele tsa hao li hlasele linaheng tse ling. Ka mohlala, lefu lena le bakoang ke lefu lena le amanang le tlhaselo e ikemetseng ka holim'a mathe a mala a hao a manyenyane. Bo-rasaense ha ba tsebe hantle hore na li-cell tsa T li etsa eng.
Le uena u ka ba le kankere e amang ka ho khetheha lymphocyte ea hau. Mofuta ona oa kankere o bitsoa boloetse ba Hodgkin kapa e seng Hodgkin lymphoma . Ho na le mefuta e fapa-fapaneng ea lefu la Hodgkin le e seng Hodgkin lymphoma, 'me mofuta oo u nang le oona o khethoa ke mofuta oa li-lymphocyte tse amehang. Lefu la Hodgkin le ama feela lisele tsa lymphocyte tsa B, le hoja e se Hodgkin lymphoma e ka kenyelletsa B cell kapa T cell lymphocytes.
