Yiziphi izimbangela zezinwele ezimpunga futhi yini ukwelashwa kwazo?

Ingabe izinwele ezimhlophe zizoba yinto yesikhathi esidlule? Yilokhu okwahlanganiswa ucwaningo lwesayensi olwaveza imbangela yangempela yezinwele ezimpunga nezindlela ezintsha zokuziqeda.

Sibona ukwamukelwa kwezinwele ezimhlophe kakhulu kunangaphambili. Kodwa naphezu kwalokhu, lesi sici sokuguga sisengenye yezinto ezinzima ekuphileni. Ngokuqondene nombuzo ohlale uhambisana nawo: Kungani izinwele ziba grey ngokukhula? Impendulo ihlobene nalokho okutholwe abacwaningi baseGrossman Medical College eNew York, futhi yembulwe muva nje kumagazini odumile wesayensi i-Nature.

Ukwembula amaqiniso angaziwa

Lolu cwaningo lubonisa izimbangela zangempela zokuguga kwezinwele ngokusekelwe ekuqapheni umsebenzi wamangqamuzana akhiqiza i-melanin kanye nendima yawo ekuguquleni izinwele zibe mpunga bese zimhlophe ngenxa yobudala. Ukwenzeka kwezinwele ezimpunga nakho kuhlobene ngokuqondile nokulahlekelwa ukunwebeka kwamangqamuzana e-stem avame ukuhamba ezimpandeni zezinwele futhi anesibopho sombala wawo wemvelo.

Lolu cwaningo luphinde luveze ukuthi isibalo salawa ma-melanocyte siyakhula ngokuya ngeminyaka, kodwa avaleleke endaweni ethile yezinwele futhi aphazamise umsebenzi wawo. Lokhu kuzozivimbela ekubuyeleni endaweni yazo yasekuqaleni lapho amaprotheni ngokuvamile ayezozenza zisebenze futhi zibe amangqamuzana ombala wezinwele.

Kulo mongo, udokotela wesikhumba uKi San waseNyuvesi yaseNew York uyachaza esitatimendeni, “Lolu cwaningo lufika ekugcwaliseni ukuqonda kwethu ukuthi amangqamuzana e-melanoma abhekele ukusebenza kombala wezinwele, kanye nezindlela ezitholwe ekuhlolweni okwenziwa kumagundane kuphakamisa ukuthi kungenzeka ukuthi i-melanocyte yomuntu. ama-stem cell anekhono elifanayo lombala izinwele.” umkhakha wokunqoba izinwele ezimpunga.”

izixazululo zesikhathi esizayo eziwusizo

Lolu cwaningo luvumele ukuqonda okwengeziwe kwendlela yokuguga kwezinwele, futhi luvula indlela yokwelashwa okusha kwale nkinga yezimonyo evamile, okwamanje enqotshwa kuphela ngokufaka imibala kwezinwele ngamakhemikhali noma odayi bemvelo.

Ngokusekelwe eqinisweni lokuthi indlela etholakala kumagundane iyafana neyabantu, lolu cwaningo luveza indlela engenzeka yokunciphisa ukubukeka kwezinwele ezimpunga kubantu ngokwenza kusebenze umsebenzi wama-melanocyte abhekele umbala wemvelo wezinwele.

Kulindeleke futhi ukuthi lolu cwaningo lunikeze indlela yokuthi izinwele zigcine umbala wazo oyisisekelo. Kusetshenzwa futhi ngomthelela wezinye izici ezidlala indima endleleni yezinwele ezimpunga, okuhlanganisa isici sofuzo kanye namazinga aphezulu okucindezeleka nokucindezeleka okubangelwa ukuphila kwesimanje.
