Icyo Beremagene Geperpavec Arimwo: Ibikoreshwa, Uburyo Bw'imiti, Ingaruka Zayo n'ibindi

Beremagene geperpavec ni uburyo bushya bwo kuvura hakoreshejwe imirasire y'urugero rwo hejuru bwo kuvura indwara ya epidermolysis bullosa (EB), indwara idasanzwe yo ku ruhu iterwa n'imiterere ya za gène ituma uruhu rworoha cyane. Ubu buryo bushya bukorwa butanga kopi nziza za gène ya COL7A1 mu turemangingo tw'uruhu rwawe, bukaba bufasha mu gukora poroteyine ya kolageni bakeneye kugira ngo bakire neza.

Niba wowe cyangwa umuntu ukunda yarwaye epidermolysis bullosa, ushobora kumva uhungabanye n'uburyo bugoye bw'ubwo buryo bushya bwo kuvura. Inkuru nziza ni uko ubu buryo bwo kuvura bugize intambwe ikomeye mu gucunga iyi ndwara igoye, butanga icyizere aho uburyo bwo kuvura bwa kera butashoboye.

Beremagene Geperpavec ni iki?

Beremagene geperpavec ni uburyo bwa mbere bwo kuvura hakoreshejwe imirasire y'urugero rwo hejuru bwemerejwe by'umwihariko indwara ya epidermolysis bullosa. Ni gel ikoreshwa ku ruhu irimo virusi zahinduwe zitwaye kopi nziza za gène ya COL7A1, umubiri wawe ukoresha kugira ngo ukore kolageni yo mu bwoko bwa VII.

Bitekereze nk'uburyo bwo gutanga butanga amabwiriza ya gène akenerwa n'uturemangingo tw'uruhu rwawe ahakenewe cyane. Ubu buryo bwo kuvura buzwi ku izina rya Vyjuvek kandi buhagarariye imyaka myinshi y'ubushakashatsi ku buryo twafasha umubiri kwikiza imbere.

Ibi si ikindi gikoresho cyangwa umuti. Ni uburyo bwo kuvura bwa biyolojiya butunganye bugamije gukemura ikibazo cy'indwara ya epidermolysis bullosa aho gucunga gusa ibimenyetso byayo.

Beremagene Geperpavec ikoreshwa mu kuvura iki?

Beremagene geperpavec ivura indwara ya epidermolysis bullosa ku barwayi bafite amezi atandatu y'amavuko n'abarenzeho. Iyi ndwara idasanzwe iterwa n'imiterere ya za gène ifata abantu hafi 1 kuri 50.000 kandi ituma uruhu rworoha cyane kandi rukagira ibibyimba.

Abantu bafite EB ya dystrophic bafite impinduka muri gene ya COL7A1, bivuze ko imibiri yabo itabasha gukora collagen ya type VII ihagije. Iyi poroteyine ikora nk'igikoresho cyo guhuza molekile gifata neza ibice by'uruhu rwawe.

Hatabayeho collagen ihagije, ndetse no gukoraho gake cyangwa guhura guto bishobora gutera ibibyimba bibabaza n'ibikomere bifunguye. Ubuvuzi bugamije by'umwihariko izi nenge za genetike binyuze mu gutanga kopi za gene nziza kugira ngo bifashe gusubiza mu buryo busanzwe imikorere y'uruhu.

Beremagene Geperpavec ikora ite?

Beremagene geperpavec ikoresha virusi ya herpes simplex yahinduwe nk'igikoresho cyo gutanga kugira ngo itware gene nziza ya COL7A1 mu turandaryi tw'uruhu rwawe. Ntukagire impungenge - virusi yarakozwe kugira ngo ibe nziza rwose kandi ntishobora gutera ubwandu cyangwa kwikorera mu mubiri wawe.

Iyo ishyizwe ku ruhu rwawe, virusi yahinduwe yinjira mu turandaryi kandi itanga amabwiriza ya genetike yo gukora collagen ya type VII. Noneho uturandaryi twawe dukoresha aya mabwiriza kugira ngo dukore poroteyine bari barabuze.

Ubu buryo bufata igihe, akenshi ibyumweru byinshi, uko umubiri wawe utangira buhoro buhoro gukora collagen nyinshi kandi uruhu rwawe rugatangira gukomera. Ubuvuzi bufatwa nk'ubufite imbaraga ziringaniye, bivuze ko butanga inyungu zigaragara ariko bisaba kwihangana no gukoresha buri gihe.
