Izazinzulu ezivela kwiZiko loPhando lweZiko lezoNyango labantwana e-Utah (CRI) lafunda isiseko se-leptin + leseli ye-leptor (ilop. Iingcali zebhayoloji zifumanise ukuba iiseli zijikeleze imithambo yegazi engalunganga kwindawo yomongo wethambo kwaye zigcine i-lymphoid ephambi kwexesha, i-skctilehesing factor (iSkf). Iimvavanyo zenzeka kwiimpuku zelebhu. Iinkcukacha zipapashwa kwimagazini yendalo.
Kwakhona, iqela lakwazi ukufumana ukuba iiseli ezilungileyo ze-Osteolektin zenza i-niche ekhethekileyo ye-iCohous kunye ne-lymphoid yandulela i-arriole. Nangona kunjalo, inani leeseli liyancipha ngobudala.
Ukujonga ukuba inkqubo inokusongelwa, ibeka amavili amanqamlezo kwiseli yenyama yelebhu - kwaye izilwanyana zakwazi ukuhlala rhoqo. Kwavela, ngenxa yomthwalo osisigxina wethambo leentonga, zomelezwa, ngelixa inani leeseli ezilungileyo ze-osteolektin kunye ne-lymphoid efikelela phambili i-arteriol yanda. Yayingumqondiso wokuqala ukuba ukhuthazo lomatshini ulawula uNiche kumongo wethambo.
Ukongeza, izazinzulu zifumanise ukuba iiseli ze-Osteolektin zichaza iPiezo1 Reftor, ebonisa ngaphakathi kwiseli ekuphenduleni kwimikhosi yoomatshini. Xa isusiwe, izilwanyana zazenza buthathaka amathambo kunye nokungaboni kakuhle.
Ngenxa yoko, iqela lafumanisa ukuba amandla edale xa ehamba okanye esebenza imithambo yegazi yegazi kumthi wethambo. Oku kukhuthaza iiseli zeComethamis kunye ne-lymphocytes ukuya kuthatha inxaxheba kwaye kunegalelo ekomelezeni amathambo kunye nogonyo. Kwangelo xesha, ukuba bayasebenza amandla eeseli zethambo ukuba baphendule kuxinzelelo olubangelwa kukuhamba koomatshini, amathambo aya kuba buthathaka, kwaye amandla okumelana nosulelo aya kuncipha.
Ngokudibeneyo, le datha ichaza indlela entsha yokuqinisa amathambo kunye nomzimba wokuzivocavoca umzimba. "Izifundo ezidlulileyo zibonakalise ukuba uqeqesho zinokuphucula amandla kunye nokuzingelwa. Sakwaziyo ukufumana indlela, ndiyabulela kuyenzeka, "Sean Morrison, uMlawuli weCrida kunye nomphandi ovela kwiZiko lezoNyango.
