I-Zika Virus isenokusetyenziselwa ukunyanga iifom zobundlongondlongo beCancer yeBongo kwixa elizayo

Umxholo

• Uphengululo lwe

Intsholongwane ka Zika ibisoloko ibonwa njengesoyikiso esiyingozi, kodwa ngendlela emangalisayo kwiindaba ze Zika, abaphandi be Washington University School of Medicine kunye ne University of California School of Medicine ngoku bakholelwa ukuba intsholongwane ingasetyenziswa njengeyeza ukubulala kunzima ukunyanga iiseli ezinomhlaza kwingqondo.

I-Zika yintsholongwane ehanjiswa yingcongconi eyona nto iphazamisayo kubafazi abakhulelweyo ngenxa yokudibana kwayo ne-microcephaly, isiphene sokuzalwa esibangela ukuba intloko yomntwana incinci kakhulu. Abantu abadala ababonakaliswe kwintsholongwane banokuba nesizathu sokukhathazeka kuba inokuba negalelo kwiimeko ezinje ngokulahleka kwememori yexesha elide kunye noxinzelelo. (Inxulumene: Ityala lokuqala losulelo lweZika lwasekhaya kulo nyaka bekuxelwe nje eTexas)

Kuzo zombini iimeko, i-Zika ichaphazela iiseli ze-stem ebuchosheni, yiyo loo nto izazinzulu zikholelwa ukuba intsholongwane inokunceda ukubulala iiseli ze-stem kwi-brain tumors.

"Sithatha intsholongwane, sifunde indlela esebenza ngayo kwaye emva koko siyayixhasa," uMichael S. Diamond, MD, Ph.D., unjingalwazi weyeza kwiYunivesithi yaseWashington yeSikole sezoNyango kunye nombhali ohamba phambili wokufunda, utshilo kwiindaba. ukukhulula. "Masisebenzise ithuba lokulunga, sisebenzise ukuphelisa iiseli esingazifuniyo. Thatha iintsholongwane ezinokuthi zenze umonakalo kwaye zibenze benze okuhle."

Besebenzisa ulwazi abaluqokeleleyo kwindlela iZika esebenza ngayo, izazinzulu zenze enye intsholongwane inokuthi amajoni ethu omzimba ahlasele ngempumelelo, ukuba angadibana neeseli ezisempilweni. Baye bafaka le nguqulo intsha kwiiseli ze-glioblastoma (eyona ndlela ixhaphakileyo yomhlaza wobuchopho) eyayisusiwe kwizigulana ezinomhlaza.

Intsholongwane ikwazile ukubulala iiseli ezinomhlaza ezihlala zixhathisa ezinye iintlobo zonyango, kubandakanya ichemotherapy. Ikwavavanywa kwiimpuku ezinamathumba engqondo kwaye yakwazi ukucutha uninzi lomhlaza. Ayisiyiyo loo nto kuphela, kodwa iimpuku ezifumene unyango oluphefumlelweyo lukaZika zihlala ixesha elide kunalezo ziphathwe nge-placebo.

Ngelixa kungakhange kubekho luvavanyo lweklinikhi lomntu, le yimpumelelo enkulu kubantu abayi-12,000 abachaphazeleka yi-glioblastoma ngonyaka.

Inyathelo elilandelayo kukubona ukuba ngaba intsholongwane inokubulala iiseli zesifo sempuku zomntu kwiimpuku. Ukusuka apho, abaphandi baya kufuna ukuqonda iZika ngcono kwaye bafunde ngokuchanekileyo Njani kwaye ngoba Ijolise kwiiseli ezinomhlaza kwingqondo kwaye ukuba zinokusetyenziselwa ukunyanga ezinye iintlobo zomhlaza onoburharha ngokunjalo.
