Ni iki Exagamglogene Autotemcel: Ibikoreshwa, Urutonde rw'imiti, Ingaruka ziterwa n'ibindi

Exagamglogene autotemcel ni uburyo bushya bwo kuvura indwara ya selile ya sikoro binyuze mu buvuzi bwo mu ntsina. Ubu buvuzi bumwe bukora buhindura selile zawe bwite z'amaraso kugira ngo zikore selile zitukura z'amaraso nziza aho gukora izo zifite sikoro zitera ububabare n'ibibazo.

Bitekereze nk'uko uha umubiri wawe amabwiriza mashya yo gukora selile z'amaraso nziza. Ubu buvuzi bukubiyemo gufata zimwe muri selile zawe z'amaraso, ukazitunganya muri laboratori, hanyuma ukazisubiza mu mubiri wawe aho zishobora gukura no gukora amaraso mazima.

Exagamglogene Autotemcel ni iki?

Exagamglogene autotemcel ni ubuvuzi bwihariye bwo mu ntsina bukorerwa mu selile zawe bwite z'amaraso. Ubu buvuzi buhindura izi selile kugira ngo zikore hemoglobin ikora neza, poroteyine itwara umwuka wa oxygène mu maraso yawe.

Ubu buvuzi bugize intambwe ikomeye ku bantu barwaye indwara ya selile ya sikoro. Bitandukanye n'ubuvuzi busanzwe buvura ibimenyetso, ubu buryo bugamije gukemura ikibazo cy'umuzi wacyo binyuze mu gufasha umubiri wawe gukora selile zitukura z'amaraso nziza mu buryo bw'umwimerere.

Ubu buvuzi buzwi kandi ku izina ry'ubucuruzi rya Lyfgenia, nubwo rwateguwe by'umwihariko ku murwayi ku giti cye. Selile zawe zahinduwe ziba umuti muzima ukomeza gukora mu mubiri wawe nyuma y'ubuvuzi.

Exagamglogene Autotemcel ikoreshwa mu kuvura iki?

Ubu buvuzi bwo mu ntsina bwemerejwe by'umwihariko kuvura indwara ya selile ya sikoro ku barwayi bafite imyaka 12 n'abarenze. Yateguwe ku bantu bafite ibibazo bikomeye biturutse ku ndwara yabo kandi bakeneye ubuvuzi buhoraho.

Muganga wawe ashobora kugusaba ubu buvuzi niba ufite ibibazo bya selile ya sikoro bitera ububabare bisaba kujyanwa mu bitaro. Bitekerezwa kandi iyo ufite ibyangiritse mu ngingo biturutse ku ndwara cyangwa iyo ubundi buvuzi butatanze ubufasha buhagije.

Ubuvuzi bufasha cyane abantu ubuzima bwabo bugirwaho ingaruka zikomeye n'indwara ya selile ya ngaruka. Bitanga icyizere cyo kugabanya kenshi kw'ibihe by'ububabare no gukumira ingorane zizaza.

Exagamglogene Autotemcel ikora ite?

Ubu buvuzi bwa jeni bukora binyuze mu guhindura selile z'amaraso yawe kugira ngo zikore ubwoko bwahinduwe bwa hemoglobin yitwa hemoglobin AT87Q. Iyi hemoglobin idasanzwe ikora neza cyane kurusha hemoglobin idafite akamaro mu ndwara ya selile ya ngaruka.

Ubu buryo butangirana no gukusanya selile zawe z'amaraso binyuze mu buryo busa no gutanga amaraso. Izi selile zikajyanwa muri laboratwari idasanzwe aho abahanga bakoresha virusi yahinduwe kugira ngo bashyiremo amabwiriza ya genetike yakosowe.

Iyo selile zahinduwe zigarutse mu mubiri wawe, zishyira mu bwoko bwawe bw'amagufa maze zigatangira gukora selile z'amaraso zitanga ubuzima. Izi selile nshya ntizishobora kurwara cyane kandi ntizitera ibibazo by'ububabare biranga indwara ya selile ya ngaruka.

Ibi bifatwa nk'ubuvuzi bukomeye kandi bushobora gukiza kuko buvura ikibazo cya genetike aho gucunga gusa ibimenyetso.

Nkwiriye gufata Exagamglogene Autotemcel nte?

Ubu buvuzi butangwa nk'urukingo rumwe rwo mu maraso mu kigo cy'ubuvuzi cyihariye. Ntushobora gufata uyu muti uri mu rugo, kuko bisaba ubugenzuzi bw'abaganga b'inzobere n'ibikoresho byihariye.
