Pfupisa nyaya yacho:  Masayendisiti eBritain ari kugadzira mushonga ungagona kusimbisa zvikuru kukwanisa kwevarwere kurwisa kenza, vakazivisa usiku hwapfuura. Chikwata chinotungamirirwa neImperial College London chakatokumbira kuti chirwere chacho chigadziriswe, icho chavanoti chingave chakagadzirira kuedzwa kwevanhu mumakore matatu. Masayendisiti akawana puroteni inobatsira kusimbisa masimba omuviri okudzivirira zvirwere zvakapetwa kagumi, chiitiko chinoshamisa chinogona kubatsira varwere kurwisa kenza nemavhairasi. Puroteni yacho inokurudzira kugadzirwa kwemasero anorwisa zvirwere anonzi cytotoxic T- cells, ayo anokwanisa kuona masero ekenza, kuatsvaka, uye kuaparadza. Puroteni yacho inokurudzira kugadzirwa kwemasero anorwisa zvirwere anonzi cytotoxic T-cells, ayo anokwanisa kuona masero ekenza, kuatsvaka, uye kuaparadza. Mukutsvaka kwetsaona mumakonzo, kwakawanwa kuti puroteni yakanga isingazivikanwi kare - iyo vakadana kuti lymphocyte expansion molecule kana kuti LEM - yakawedzera zvikuru nhamba yamasero eT mumuviri. Iye zvino vari kugadzira mushonga wemagene uyo ungawedzera kugadzirwa kwemapuroteni anonzi LEM, zvichiita kuti pave nemasero anonzi T akawanda anokwanisa kurwisa masero ekenza. Kurapa kwacho, kwakaziviswa mumagazini yenyika yose yeScience usiku hwapfuura, kwaizoshandisa masero-T aripo anotorwa kuvarwere vamwe navamwe. Masero omurwere aizobviswa, achinjwa nokuiswa kwemajini anogadzira LEM, uye ipapo aizodzorerwa mumurwere kupfurikidza nokudonhedzwa, zvichida kanokwana kana mumwedzi miviri. Yakati yaigonawo kushandiswa kurapa mamwe mavhairasi. Kubudirira, uko kwaibatanidzawo vatsvakurudzi vanobva kuQueen Mary University yeLondon, ETH Zurich muSwitzerland neHarvard Medical School muU.S., kwave kuripo kwemakore matanhatu. Masero anonzi cytotoxic T-cells anokosha pakuita kuti muviri urambe uchidzivirira zvirwere, asi paanosangana nezvirwere zvakakomba kana kuti kenza yakakura, kazhinji haakwanisi kuunganidza masero akawanda zvakakwana kuti arwise chirwere chacho. Mukutsvaka kwetsaona mumakonzo, kwakawanwa kuti puroteni isingazivikanwi kare - iyo vakadana kuti kuwedzera kwemarymphocyte...
Kurapa kwakagadzirwa nechikwata cheBritain kunogona kuwedzera mano okurwisa kenza. Imperial College London inoti miedzo yevanhu yokurapa ingatanga mumakore matatu. Protein yakawanwa yaigona kusimbisa masimba omuviri kurwisa kenza kagumi. Kuwana kwetsaona kwakaitwa apo morekuru risingazivikanwi rakawanwa mumakonzo.
