Mishonga inodzivisa kushanda kweprotein system system - gamma interferon inodzivisa kukura kwe melanoma - kenza yeganda ine ngozi - maererano nemasayendisiti eUnited States mumagazini Nature.
Kuratidzwa kune ultraviolet mwenje uye mwaranzi ndizvo zviviri zvinokonzeresa kukura kwemelanoma - iyo yakaipisisa kenza yeganda. Nehurombo, kusvika parizvino mamorekuru ekukura kwegomarara iri haana kunyatsonzwisiswa.
Glenn Merlino nevamwe vaaishanda navo kubva kuNational Cancer Institute muBethesda vakadzidza mhedzisiro yemwaranzi yeUVB mumakonzo. Masayendisiti akaratidza kuti UVB inokonzera macrophages kuyerera muganda. Macrophages imhando yemasero machena eropa, masero anogadzira interferon gamma, puroteni iyo kemikari inoratidza kukura kwe melanoma.
Kuvharidzirwa kwebasa re interferon gamma (kureva interferon type II) nerubatsiro rwema antibodies akakodzera anodzivisa kukura kusina kujairika kwemasero eganda uye kukura kwekenza, kuvharidzirwa kwe interferon I basa hakuna zvakadaro.
Type I interferons inozivikanwa semapuroteni anorwisa cancer uye imwe yacho, interferon alpha, inoshandiswa kurapa melanoma. Kuwanikwa kwekuti gamma interferon ine zvinopesana uye inosimudzira kukura kwegomarara kunoshamisa. Kudzivirirwa kwegamma interferon kana mapuroteni ainobata kunoita seyakanaka chinangwa chekurapa melanoma. (PAP)
