\nUn nou model teoretic care descrie r\u0103sp\u00e2ndirea HIV \u00een organism arat\u0103 faptul c\u0103 acest virus se propag\u0103 dup\u0103 un tipar similar urmat de anumi\u0163i viru\u015fi informatici, informeaz\u0103 dailymail.co.uk.

\nEi au creat \u00eempreun\u0103 un model de “r\u0103sp\u00e2ndire hibrid\u0103”, care a prezis cu un grad ridicat de acurate\u0163e evolu\u0163ia pacien\u0163ilor de la stadiul de “infecta\u0163i cu HIV” la stadiul de “bolnavi de SIDA”, \u00een cadrul unui studiu clinic de amploare. Potrivit acestor speciali\u015fti, depistarea infec\u0163iei \u00eentr-un stadiu incipient reprezint\u0103 elementul cheie \u00een tratarea bolii.<\/strong><\/p>\n \nCercet\u0103torii au remarcat c\u0103 HIV se r\u0103sp\u00e2nde\u015fte \u00een organism folosind dou\u0103 metode – prin fluxul sangvin \u015fi direct \u00eentre celule. Anumi\u0163i viru\u015fi folosesc acelea\u015fi metode pentru a se r\u0103sp\u00e2ndi, at\u00e2t pe internet, c\u00e2t \u015fi \u00een re\u0163elele locale, pentru a infecta c\u00e2t mai multe computere.<\/p>\n \nModelul teoretic a fost inspirat de similarit\u0103\u0163ile prezentate de HIV \u015fi de un virus informatic extrem de d\u0103un\u0103tor, denumit “viermele Conficker”, detectat \u00een premier\u0103 \u00een anul 2008, care a infectat re\u0163elele informatice militare \u015fi de poli\u0163ie din Europa \u015fi care este activ \u015fi \u00een prezent.<\/p>\n \nChangwang Zhang, cercet\u0103tor la UCL \u015fi coordonator al studiului, a declarat: “HIV \u015fi Conficker au multe lucruri \u00een comun. Ambele folosesc mecanisme hibride de r\u0103sp\u00e2ndire, persist\u0103 pentru o perioad\u0103 \u00eendelungat\u0103 \u015fi sunt incredibil de greu de eradicat. Modelul nostru teoretic ne permite s\u0103 explic\u0103m mai bine aceste propriet\u0103\u0163i importante \u015fi ne ajut\u0103 s\u0103 anticip\u0103m mai u\u015for procesul de infectare”.<\/p>\n \nProfesorul Shi Zhou, un alt autor al studiului, a ad\u0103ugat: “De\u015fi speciali\u015ftii din comunitatea din spa\u0163iul cibernetic au organizat o colaborare f\u0103r\u0103 precedent pentru a stopa Conficker, ei au e\u015fuat \u00een \u00eencercarea lor de a elimina Conficker de pe internet. Cercet\u0103torii contra HIV se confrunt\u0103 cu o problem\u0103 similar\u0103. Sper\u0103m c\u0103 noul nostru studiu despre epidemiile hibride ne va ajuta s\u0103 lupt\u0103m mai eficient \u00eempotriva Conficker \u015fi HIV”.<\/p>\n \nAnalizele detaliate efectuate pe probe sangvine recoltate de la 17 pacien\u0163i din Londra infecta\u0163i cu HIV au fost utilizate pentru a verifica validitatea acestui model teoretic. Ele au demonstrat c\u0103 r\u0103sp\u00e2ndirea hibrid\u0103 reprezint\u0103 cea mai bun\u0103 explica\u0163ie pentru progresia HIV \u00een organism \u015fi au subliniat beneficiile aduse de tratamentele administrate \u00een stadii incipiente ale infec\u0163iei.<\/p>\n \nHIV infecteaz\u0103 celulele T, care joac\u0103 un rol vital \u00een func\u0163ionarea sistemului imunitar, protej\u00e2nd organismul de boli.
