LOND\u00ddN – V\u00fdskumn\u00edci z Brit\u00e1nie a Kene identifikovali nov\u00fd koronav\u00edrus u netopierov, ktor\u00fd dok\u00e1\u017ee prenika\u0165 do \u013eudsk\u00fdch buniek. Hoci sa zatia\u013e na \u013eud\u00ed nepreniesol, odborn\u00edci upozor\u0148uj\u00fa na potenci\u00e1lne riziko a vyz\u00fdvaj\u00fa na d\u00f4sledn\u00e9 sledovanie.<\/p>\n

\t\t\t\tObjav, ktor\u00fd vyvolal obavy<\/p>\n

Medzin\u00e1rodn\u00fd t\u00edm vedcov upozornil na nov\u00fd typ koronav\u00edrusu ozna\u010den\u00fd ako CcCoV-KY43. V\u00edrus sa nach\u00e1dza u netopierov s charakteristick\u00fdm \u201esrdcovit\u00fdm\u201c nosom, ktor\u00e9 \u017eij\u00fa najm\u00e4 vo v\u00fdchodnej Afrike \u2013 v oblastiach Sud\u00e1nu, Kene \u010di Tanz\u00e1nie.<\/p>\n

Laborat\u00f3rne testy uk\u00e1zali, \u017ee tento v\u00edrus je schopn\u00fd viaza\u0165 sa na receptory v \u013eudsk\u00fdch p\u013e\u00facach, \u010do je k\u013e\u00fa\u010dov\u00fd krok pre vznik infekcie. V\u00fdskumn\u00edci v\u0161ak zd\u00f4raz\u0148uj\u00fa, \u017ee zatia\u013e neexistuj\u00fa d\u00f4kazy o tom, \u017ee by sa u\u017e preniesol na \u010dloveka, p\u00ed\u0161e Daily Star<\/a>.<\/p>\n

Ako v\u00edrus prenik\u00e1 do buniek<\/p>\n

Vedci sa zamerali na tzv. spike prote\u00edny \u2013 \u010dasti v\u00edrusu, ktor\u00e9 mu umo\u017e\u0148uj\u00fa \u201eprichyti\u0165 sa\u201c k bunk\u00e1m a prenikn\u00fa\u0165 do nich. Analyzovali desiatky variantov t\u00fdchto prote\u00ednov a porovn\u00e1vali ich s receptormi nach\u00e1dzaj\u00facimi sa v \u013eudskom tele.<\/p>\n

Pod\u013ea odborn\u00edka z The Pirbright Institute Dalana Baileyho sa doteraz predpokladalo, \u017ee tieto v\u00edrusy vyu\u017e\u00edvaj\u00fa len obmedzen\u00fd po\u010det \u201evstupn\u00fdch br\u00e1n\u201c. \u201ePred na\u0161\u00edm v\u00fdskumom sa predpokladalo, \u017ee v\u00e4\u010d\u0161ina alfakoronav\u00edrusov pou\u017e\u00edva jeden alebo dva receptory na vstup do hostite\u013ea. Teraz vieme, \u017ee ich m\u00f4\u017eu vyu\u017e\u00edva\u0165 ove\u013ea viac,\u201c vysvetlil.<\/p>\n

Riziko, ktor\u00e9 netreba podceni\u0165<\/p>\n

V\u00fdsledky pod\u013ea vedcov nazna\u010duj\u00fa, \u017ee podobn\u00e9 v\u00edrusy maj\u00fa \u0161ir\u0161\u00ed potenci\u00e1l infikova\u0165 \u013eud\u00ed, ne\u017e sa p\u00f4vodne myslelo. Aj ke\u010f sa nov\u00fd v\u00edrus zatia\u013e v \u013eudskej popul\u00e1cii nepotvrdil, odborn\u00edci varuj\u00fa, \u017ee situ\u00e1ciu treba pozorne sledova\u0165.<\/p>\n

Stephen Graham prirovnal fungovanie v\u00edrusu k mechanizmu k\u013e\u00fa\u010da a z\u00e1mku. \u201eV\u00edrusov\u00e9 spike prote\u00edny s\u00fa ako k\u013e\u00fa\u010de, ktor\u00e9 zapadaj\u00fa do z\u00e1mkov na bunk\u00e1ch a umo\u017e\u0148uj\u00fa im vstup. Zatia\u013e sme identifikovali jeden receptor, no v\u00fdzvou je n\u00e1js\u0165 \u010fal\u0161ie,\u201c uviedol.<\/p>\n

Z\u00e1rove\u0148 zd\u00f4raznil, \u017ee riziko tu existuje u\u017e dlh\u0161ie. \u201eJe to ako prech\u00e1dza\u0165 cez cestu \u2013 rad\u0161ej to urob\u00edm s otvoren\u00fdmi o\u010dami,\u201c dodal.<\/p>\n

V\u00fdskum m\u00e1 pom\u00f4c\u0165 pripravi\u0165 sa<\/p>\n

Vedci veria, \u017ee nov\u00e9 poznatky umo\u017enia lep\u0161ie pochopi\u0165 potenci\u00e1lne hrozby a pripravi\u0165 sa na pr\u00edpadn\u00e9 bud\u00face prenosy zo zvierat na \u013eud\u00ed.<\/p>\n

Giulia Gallo upozornila, \u017ee \u0161t\u00fadia bola realizovan\u00e1 bezpe\u010dn\u00fdm sp\u00f4sobom bez potreby manipul\u00e1cie so \u017eiv\u00fdm v\u00edrusom.<\/p>\n

Pod\u013ea Jamesa Nyagwangea m\u00f4\u017eu tieto zistenia pom\u00f4c\u0165 aj pri v\u00fdvoji vakc\u00edn a antivirot\u00edk. \u201ePom\u00f4\u017ee to \u013eudstvu pripravi\u0165 sa na pr\u00edpadn\u00fd prenos v bud\u00facnosti,\u201c uviedol.<\/p>\n

Odborn\u00edci volaj\u00fa po ostra\u017eitosti<\/p>\n

Aj ke\u010f bezprostredn\u00e9 riziko pand\u00e9mie zatia\u013e nehroz\u00ed, vedci zd\u00f4raz\u0148uj\u00fa potrebu monitorovania v\u00edrusov u netopierov a sledovania mo\u017en\u00fdch mut\u00e1ci\u00ed. Pr\u00e1ve v\u010dasn\u00e9 odhalenie podobn\u00fdch hrozieb m\u00f4\u017ee rozhodn\u00fa\u0165 o tom, \u010di sa podar\u00ed zabr\u00e1ni\u0165 \u010fal\u0161ej glob\u00e1lnej kr\u00edze.<\/p>\n
