Kodi chimfine mbalame mutate ndi chifukwa mliri pakati pa anthu?

Asayansi phunziro zatsopano zasayansi amene anasonyeza kuti mchikakamizo cha atatu kusintha yosavuta chimfine avian lingatithandize luso kufalitsa kwa munthu wina ndi mzake.

Koma usaope kuyang'ana suti ndi chitetezo kwachilengedwenso: ofufuza za sanasinthe HIV yokha (ife nonse mwaziwona mafilimu zokwanira za masoka kupewa cholakwa). M'malo mwake, izi kafukufuku zosaneneka kudzakuthandizani asayansi kukhala patsogolo pa HIV kupewa kufalitsa angathe.

Koopsa chimfine mbalame

Akatswiri chidwi kupsyinjika otchedwa avian fuluwenza A (H7N9). Malinga WHO, mu 2013, HIV chakukhudza anthu oposa 900. Komabe, ambiri a milandu anali pachibale ndi anthu omwe amagwira ntchito ku nkhuku kuyambira HIV yokha sangathe odula anthu.

Pankhani kwambiri, HIV mwina mutate mu mawonekedwe kuti athe kufalitsa kwa anthu, ndipo zingakhale anayamba kufalitsa ngati moto. Choncho, asayansi ku California ntchito ndi zosiyanasiyana masinthidwe matupi a H7N9, kuona zimene zingathandize HIV kufalitsa anthu.

masinthidwe yosavuta

Asayansi ntchito ndi mapuloteni padziko HIV amatchedwa hemagglutinin H7. Timatha HIV kuti amange mwamantha maselo kupatsira iwo.

Iwo anapeza kuti mapuloteni izi chingathe cha masinthidwe yaing'ono zidulo atatu kwa amino anapeza padziko HIV kuti amalola kuti anamanga bwino maselo maselo pa maselo a anthu, poyerekeza maselo mbalame.

Zasayansi, asayansi anapanga patatu ZOOPSA haemagglutinin H7 ndipo anaona kuti akhoza bwinobwino apeze poponda pa maselo mwa munthu zitsanzo trachea minofu.

Kodi padzakhala mliri?

malamulo Safety amaletsa kulowa cha masinthidwe amenewa mavairasi izi H7N9, kotero Olemba kuphunzira amanena kuti iwo sadalengedwe HIV, ndi kokha ntchito chosaopsa mpukutu zace. Masinthidwe ndi weniweni H7N9 kuimira zatsopano ndi kuchuluka ntchito tizilombo kuti panopa zoletsedwa (zifukwa zoonekeratu).

Ndipo komabe, kaya kuopa anapezazo izi? Zikuoneka sichinafike. Fiona Kalli, katswiri wa Immunology kupuma pa Imperial College London, limanena kuti mwayi wa mawonetseredwe munthawi yomweyo masinthidwe onse atatu "wotsika."

"Kafukufuku itithandiza mosamala kwambiri kuchepetsa mavuto kugwirizana ndi fuluwenza avian, ndi kuonjezera nzeru zathu zomwe ndi HIV avian fuluwenza akhoza kukhala oopsa" - iye anati.
