100CM Mini Bonde Chidhori chevakuru

Kuwanda kwehutachiwana

Delta haingotapurirane kupfuura yapfuura SARS-CoV-2 akasiyana, inogona zvakare kukonzera chirwere chakanyanya. Vanhu vanotapukirwa nechiteshi chengarava cheDelta chakapetwa ka1,000 nhamba yehutachiona (uyo nyanzvi dzinodaidza kuti "viral load") mumhino dzavo zvichienzaniswa neavo vakatapukirwa neimwe rudzi, "kunova kuwedzera kukuru," anodaro Eric Topol, muvambi uye mutungamiriri weScripps Research Translational Institute, asina kubatikana muchidzidzo ichi.

Chimwe chikonzero cheizvi ndechekuti iyo Delta musiyano inodzokorora nekukurumidza mumhino. Ongororo, isati yaongororwa nevezera yakaratidza kuti musiyano weDelta wakatora avhareji yemazuva mana kusvika padanho rinoonekwa mushure mekusangana nemunhu anorwara, zvichienzaniswa nemazuva matanhatu ehutachiona hwekutanga hweWuhan.

Kunyangwe mushure mekubaiwa, hutachiona hweDelta hwakagadzira huwandu hwehutachiwana hwakapetwa kagumi pane husina hutachiona hweDelta. Zvakadaro ongororo dzakati wandei dzichangoburwa, hapana mumwe wevezera rake akaongororwa, anoratidza kuti vanhu vakabaiwa vanotakura hutachiwana hwakafanana nehwevasina kubayiwa. “Tiri kuona utachiona uye kuona huwandu hwevanhu vari kubatwa nechirwere chimwe chete, izvo zviri kunetsa. Zvinoreva kuti hutachiona hunotapuriranwa zvakanyanya uye hunokwanisa kudzivirira ... kudzivirira-induced immune immune, "akadaro Ravindra Gupta, chiremba wekiriniki microbiologist paUniversity yeCambridge, akatungamira chidzidzo icho chisati chaongororwa.

Delta zvakare iri nani pakuparadza maseru nekuda kwekuchinja kuri pachinzvimbo 681 cheprotein yayo, iyo iri kukurumidza kuwanda mune mamwe akasiyana pasirese uye inofungidzirwa kuve shanduko yemutambo. Uku kuchinja kweP681R kunoita kuti zvive nyore kuDelta nemhando dzakasiyana dzeKappa kuti dzipinde musero rekugamuchira nekusanganisa maseru ane utachiona muzvimiro zvinodaidzwa kuti syncytium, inova nzira yekumhanyisa hutachiona. Syncytia inoumbwawo nemamwe mavhairasi akaita seHIV. "Takawana mune masero etsika kuyedza kuti Delta musiyano unoratidza yakakura syncytia kana ichienzaniswa neSARS-CoV-2," akatsanangura Kei Sato, chiremba wehutachiona paYunivhesiti yeTokyo, Japan.

Musiyano weDelta wakaitawo shanduko dzakawanda muprotein yayo inoita kunge inovandudza kugona kwehutachiona kusunga kune ACE2 receptor uye kunzvenga mhinduro yeimmune.
