Ka tuyige ku butoffaali bwa B mu ngeri ennyangu? Obukuumi obutono obw’omubiri gwo!

Wali weebuuzizzaako oba waliwo olutalo olutalabika olugenda mu maaso munda mu mibiri gyaffe buli kiseera? Yee, kituufu. Obukuumi obutono obuli munda mu mibiri gyaffe bulwanyisa obuwuka obuleeta endwadde eziva ebweru. Ekibinja ekikulu ennyo mu bakuumi abo bwe butoffaali buno obwa B. Leero tugenda kwogera ku butoffaali buno obwa B n’engeri gye butukuumamu endwadde.

Ddala obutoffaali bwa B kye ki?

Obutoffaali bwa B, nga bwe kyayogeddwako emabegako, kika kya butoffaali obweru mu musaayi gwaffe. Era tuziyita `(B lymphocytes)`. Obutoffaali buno obwa B kitundu kikulu nnyo mu baserikale b’omubiri gwo, enkola y’omubiri ekuuma endwadde. Omulimu gwabwe omukulu kwe kukola obutoffaali obw’enjawulo obuyitibwa `(antibodies)` okulwanyisa `(pathogens)` ez’obulabe – ebintu nga akawuka, obuwuka, n’obuwuka – obuyingira mu mubiri.

Obutoffaali bwa B n’obutoffaali bwa T bika bya butoffaali bibiri ebibeera mu kika ky’obutoffaali obweru obw’enjawulo obuyitibwa lymphocytes. Lymphocytes zino zilwanyisa ebiyingirira n’obutoffaali obutali bwa bulijjo ng’obutoffaali bwa kookolo. Obutoffaali bwa T busaanyawo obuwuka obuleeta endwadde era ne bukwasaganya abaserikale b’omubiri nga buweereza obubonero mu bitundu by’omubiri ebirala. Ate obutoffaali bwa B bukola antibodies nga buddamu antigens. Antigens ziringa endagamuntu. Ebirungo bino ebiziyiza endwadde biyamba abaserikale baffe okutegeera ebintu ebiri mu mubiri gwaffe naddala eby’obulabe nga akawuka ne bakitiriya.

Bika ki ebikulu eby’obutoffaali bwa B?

Okay, kati omanyi obutoffaali bwa B kye buli. Waliwo ebika by’obutoffaali bwa B bibiri ebikulu. Zino butoffaali bwa plasma n’obutoffaali obujjukira. Ebika bino byombi biyamba okutukuuma obutakwatibwa ndwadde. Ka tulabe engeri.

Obutoffaali bwa plasma

Obutoffaali buno obwa pulasima bwe bufulumya obuziyiza obuziyiza endwadde nga buddamu obusimu obuziyiza endwadde obwogeddwako emabegako. Kilowoozeeko ng’okukuba omulabe amasasi ng’olaba. Akatoffaali ka B bwe kamala okukyuka ne kafuuka akatoffaali ka plasma, kasobola okufulumya obuwuka obuziyiza endwadde nga 2,000 buli sikonda! Ekyo si kyewuunyisa? Obutoffaali buno obwa pulasima era buyitibwa plasmacytes ne effector cells. Kyokka, obulamu bwazo bumpi katono okusinga obw’obutoffaali obujjukira.

Obutoffaali obujjukira

Erinnya likiraga, nedda? Obutoffaali buno obw’okujjukira bujjukira antigens ezenjawulo. Olwo, singa antigen eyo edda mu mubiri gwaffe mu biseera eby’omu maaso, abaserikale baffe abaserikale basobola okukola amangu, nga balinga abateekateeka, okukola eby’okwekuuma. Nga bwe twandizzeemu mangu omulabe amanyiddwa. Obutoffaali bwa plasma bwe bukola obutoffaali obuziyiza endwadde ne bulwanyisa abalumbaganyi mu kiseera ekyo, obutoffaali obujjukira butuyamba okulwana entalo ez’omu maaso. Okugeza, eno y’engeri eddagala erigema gye tufunamu emirimu. Eddagala erigema kye likola kwe kuyingiza abaserikale baffe abaziyiza endwadde mu antigen emu. Olwo obutoffaali bwaffe obw’okujjukira ne bukijjukira. Singa ddala obuwuka obwo bukomawo oluvannyuma, omubiri gwaffe gusobola okugulumba amangu.

Lwaki obutoffaali bwa B bukulu gye tuli?

Obutoffaali bwa B kitundu kikulu nnyo mu nkola yaffe ey’abaserikale b’omubiri (adaptive immune system). Kati oyinza okuba nga weebuuza nti abaserikale b’omubiri abakyukakyuka (adaptive immune system) kye ki. Waliwo ebitundu bibiri ebikulu eby’abaserikale b’omubiri gwaffe. Ekimu kye baserikale b’omubiri abazaalibwa nabyo, ate ekirala ye baserikale b’omubiri abakwatagana n’embeera. Abaserikale b’omubiri abazaalibwa nabo balinga layini esooka ey’okwekuuma, nga baddamu okutiisibwatiisibwa kwonna. Naye abaserikale b’omubiri abakyukakyuka (adaptive immune system) basinga kuba ba njawulo. Kitegeera akabi akagere – kwe kugamba, akawuka akagere, obuwuka, n’ebirala – era ne kakirwanyisa.

Kale, obutoffaali bwa B kye bukola kwe kukola antibodies ezisaanyaawo antigen eyo oba pathogen eyesibye ku antigen eyo. Ate era, obutoffaali bwa B busobola okujjukira antigens ezenjawulo. Olwo, singa obuwuka obwo budda mu mubiri, abaserikale baffe abaserikale b’omubiri basobola okukola eky’okwekuuma obulungi ennyo. Mu ngeri ennyangu, singa tewaali butoffaali bwa B, omubiri gwaffe tegwandisobodde kutegeera balabe bennyini, okukola ebyokulwanyisa ebitongole (antibodies) okubalwanyisa, n’okujjukira abalabe abo ne bakola mangu singa bakomawo.

Obutoffaali bwa B bukola butya mu baserikale b’omubiri?

Wadde nga nkola nzibu nnyo, ka tugezeeko okugitegeera mu ngeri ennyangu. Obutoffaali bwa B, awamu n’obutoffaali obulala mu baserikale b’omubiri, bulwanyisa ebirungo eby’obulabe ebitulwaza, awamu n’obutoffaali obutali bwa bulijjo ng’obutoffaali bwa kookolo. Akatoffaali ka B bwe kamala ‘okukola’, kafuuka katoffaali ka plasma, akakola obuziyiza obuziyiza endwadde nga kaddamu antigen, oba kafuuka akatoffaali akajjukira, akajjukira antigen eyo. Mu ngeri eyo, singa ekomawo mu biseera eby’omu maaso, esobola okukitegeera amangu n’okukirwanyisa.

Mu budde obwabulijjo, abaserikale b’omubiri bwe beetaaga obutoffaali bwa B okulwanyisa omulumbaganyi, bino bye bimu ku bibaawo:

• Okusooka, akatoffaali ak’enjawulo akayitibwa akatoffaali akalaga antigen (APC) kakwatagana ku antigen y’omulumbaganyi ne kakutukamu obutundutundu obutonotono. Olwo APC n’ekwata ebitundu bya antigen ku molekyu eyitibwa Major Histocompatibility-II complex (MHC-II).
• Ekiddako, obutoffaali bwa T obuyambi (nabwo ekika ky’obutoffaali bwa T) buyingira ne bukwatagana n’ekizibu ekyo ekya MHC-II. Okusiba kuno kwe kukola obutoffaali bwa T obuyambi. Obutoffaali buno obuyamba T bukulu nnyo kubanga bwe buwa obubonero obulaga obutoffaali bwa B ‘okutuuka ku mulimu’.
• Akatoffaali ka T akakola (activated T cell) yeekwata ku katoffaali ka B. Olwo akatoffaali ako aka B katandika okwekolera kkopi, oba ``clones.'' Obumu ku butoffaali buno obwa B bufuuka obutoffaali bwa plasma, obusobola okukola obuziyiza. Obutoffaali bwa B obulala bufuuka obutoffaali obujjukira ne buterekebwa mu mubiri.
• Mu nnaku eziddako, obutoffaali bwa plasma bukola obukadde n’obukadde bw’obutoffaali obuziyiza endwadde. Buli emu ku buziyiza buno ekolebwa okusaanyaawo obuwuka obw’enjawulo obwakola antigen eyo yokka. Kino kitegeeza nti antibody emu esobola okutunuulira ekika ky’omulabe kimu kyokka.
• Antibodies zino zeekwata ku antigen oba ekitundu ky’obuwuka obuleeta endwadde ekirina akabonero akalaga antigenic. Obuwuka buno bwe bumala okwegatta, tebukyayinza kukola bulabe ku mubiri.

Kilowoozeeko ng’ekikwekweto kya poliisi. Okusooka, siginiini eyingira (okutegeera antigen okukolebwa APC). Olwo ttiimu ey’enjawulo (obutoffaali bwa T obuyambi) n’ejja mu nkola, n’etegeeza ttiimu endala (obutoffaali bwa B). Ekitundu kya ttiimu eyo kigenda mu lutalo amangu ago (obutoffaali bwa plasma), ate ekitundu ekirala ne kyetegekera ebiyinza okutiisa mu biseera eby’omu maaso (obutoffaali obujjukira).

Obutoffaali bwa B busangibwa wa?

Ekifo obutoffaali bwa B we bubeera kyawukana okusinziira ku mutendera gw’okukula kwabwo. Lowooza ku kino, bw’oba ​​omwana mu lubuto, kwe kugamba, mu lubuto lwa maama wo, obutoffaali bwa B bukolebwa mu kibumba. Naye oluvannyuma lw’okuzaalibwa, obutoffaali bwa B bukula mu kitundu ekigonvu era ekiringa sipongi munda mu magumba gaffe. Ekyo kye tuyita obusigo bw’amagumba. Zitandika nga obutoffaali obusibuka mu musaayi (hematopoietic stem cells). Olwo, okuyita mu nkola eyitibwa hematopoiesis, zifuuka obutoffaali bwa B. Obutoffaali bwo obwa B bwe bumala okukula mu bujjuvu, bugenda mu bitundu ebikulu eby’enkola yo ey’amazzi. Okugeza, ennywanto n’ennywanto.

Endwadde ki ezitera okubaawo eziyinza okubaawo nga zeekuusa ku butoffaali bwa B?

Singa ekintu ekitali kya bulijjo kituuka ku butoffaali bwaffe obwa B, kiyinza okuvaako endwadde z’abaserikale b’omubiri n’ebika bya kookolo eby’enjawulo. Ka tulabe ekyo.

Endwadde z’abaserikale b’omubiri (autoimmune diseases).

Oluusi, kino kye kibaawo. Obutoffaali bwaffe obwa B bukola antibodies nga buddamu antigens ku butoffaali bwaffe obulamu. Olwo, obuziyiza obwo bulumba obutoffaali bwaffe obulamu nga bulinga obulumbye obuwuka obw’akabi. Kiringa okulumba amaka gaffe gennyini. Ekyo kye tuyita endwadde z’abaserikale b’omubiri (autoimmune diseases). Wano waliwo ebyokulabirako ebitonotono:

• Lupus
• Obulwadde bw’okuzimba omubiri (multiple sclerosis).
• Obulwadde bw’endwadde z’enkizi
• Ssukaali ow’ekika kya 1

Kookolo

Waliwo ebika bya kookolo ebiwerako ebikwatagana n’okukula kw’obutoffaali bwa B mu ngeri etaali ya bulijjo. Kino kitegeeza nti obutoffaali bwa B butandika okweyongera mu ngeri etafugibwa. Ebimu ku byo bye bino:

• Obulwadde bwa leukemia obuyitibwa lymphocytic leukemia
• Obulwadde bwa lymphocytic leukemia obutawona
• Obulwadde bwa Hodgkin lymphoma
• Obulwadde bwa lymphoma obutali bwa Hodgkin
• Obulwadde bw’obutoffaali bwa B `(B-cell lymphoma)`
• Obulwadde bwa myeloma obuyitibwa multiple myeloma
• Obulwadde bwa Waldenström obuyitibwa macroglobulinemia

Obutoffaali bwa B buli kitundu ki ekyabulijjo?

Omuntu omukulu owa bulijjo alina obutoffaali obuyitibwa lymphocytes wakati wa 1,000 ne 4,800 buli microliter y’omusaayi. Obutoffaali bwa B bukola ebitundu nga 10% ku 20% ku lymphocytes zo zonna.

Naye jjukira nti singa omuwendo gw’obutoffaali bwo obwa B buli kiseera guba mungi nnyo oba nga mutono nnyo, kiyinza okutegeeza nti olina embeera y’obujjanjabi. Omusawo ajja kwetaaga okukola okukebera okuzuula ekituufu.

Biki ebitera okukeberebwa okukebera obulamu bw’obutoffaali bwange obwa B?

Omusawo asobola okumanya obutoffaali bw’omusaayi bw’olina mu mubiri gwo ng’akozesa okukebera okwangu okuyitibwa Complete Blood Count (CBC). Kyokka, tewa mawulire ku bika bya lymphocytes ebitongole, gamba ng’obutoffaali bwa B n’obutoffaali bwa T.

Singa omusawo wo ateebereza nti olina obulwadde obukwatagana n’obutabeera bwa bulijjo mu butoffaali bwo obwa B, ayinza okulagira okukeberebwa okulala okuwa amawulire agakwata ku bika by’obutoffaali ebitongole, gamba ng’ebifaananyi by’obutoffaali obuyitibwa lymphocyte profile (omuwendo gw’obutoffaali bwa T ne B), oba ekibiina kya B-cell leukemia/lymphoma panel.

Kiki kye tuyinza okukola okukuuma obutoffaali bwaffe obwa B nga bulamu bulungi?

Tewali ngeri ya butonde ekkirizibwa nnyo ey’oku ‘okutumbula’ obutoffaali bwa B. Wabula waliwo by’oyinza okukola okukuuma abaserikale b’omubiri nga balamu bulungi n’okukuuma obutoffaali bwa B bw’olina edda. Ebintu bino bingi biyinza okulabika ng’eby’amagezi, naye mu butuufu biziyiza obutoffaali bw’omubiri gwo obwa B, n’ebintu ebirala eby’omuwendo eby’abaserikale b’omubiri, okwonooneka. Nga mmotoka zaffe bwe ziwangaala singa ziba ziddaabirizibwa bulungi.

Ebintu bino osobola okubikola okukuuma abaserikale b’omubiri nga balamu bulungi:

• Funa eddagala lyonna erigema.
• Lya emmere ennungi era ey’enjawulo.
• Dukanya bulungi situleesi yo.
• Weewale okunywa omwenge, oba gukozese mu kigero.
• Weewale okunywa sigala (sigala, vaping). Bw’oba ​​okola bw’otyo, lekera awo.
• Weebake waakiri essaawa musanvu ku munaana buli kiro.
• Weenyigira mu dduyiro ow’ekigero waakiri eddakiika 150 buli wiiki.
• Naaba mu ngalo buli kiseera ne ssabbuuni oba kozesa eddagala erirongoosa mu ngalo.

Njawulo ki eriwo wakati w’obutoffaali bwa T n’obutoffaali bwa B?

Obutoffaali bwa T, obutoffaali bwa B, n’obutoffaali bwa B byombi bitukuuma okuva ku buwuka obuleeta endwadde. Naye zikola emirimu egy’enjawulo mu baserikale b’omubiri. Obutoffaali bwa T busindika obubonero obufuga okuddamu kw’abaserikale b’omubiri (buno buyitibwa obutoffaali bwa T obuyambi) oba busaanyaawo butereevu obuwuka obuleeta endwadde oba obutoffaali obulina akawuka (buno buyitibwa obutoffaali bwa T obutwa).

Naye obutoffaali bwa B bukola obutoffaali obuyitibwa antibodies nga buddamu antigens, nga buno bubonero obutegeeza omubiri nti omulumbaganyi ayingidde mu mubiri. Ekikulu nti omulumbaganyi tayimirizibwa butereevu katoffaali ka B, wabula obutoffaali obuziyiza endwadde obutoffaali bwa B bwe bukola.

N’ekisembayo, ebintu by’olina okujjukira

Kale, awatali butoffaali bwa B, emibiri gyaffe tegyandisobodde kukola buziyiza. Antibodies zino proteins nkulu nnyo eziyamba okulwanyisa obuwuka obw’obulabe. Ng’oggyeeko obutoffaali obulala obuyitibwa lymphocytes n’obutoffaali obweru, obutoffaali bwo obwa B bwe bukukuuma nga tolina bulwadde n’okukukuuma okuva ku butoffaali obutali bwa bulijjo.

Kale, faayo ku butoffaali bwo obwa B. Kola ebintu buli lunaku ebiyamba okukuuma abaserikale bwo bonna nga balamu bulungi. Nga bwe kyayogeddwako emabegako, lya bulungi, weebake bulungi, dduyiro, kendeeza ku situleesi, era funa amasasi mu budde. Ebintu bino ebyangu bijja kuwa obukuumi buno obutono mu mubiri gwo amaanyi mangi.
