\nOamenii de \u015ftiin\u0163\u0103 de la Queen Mary University of London \u015fi Francis Crick Institute au studiat efectele cafelei asupra celulelor de drojdie, care sunt folosite ca substitut pentru celulele umane \u00een cercetare.<\/p>\n
\nCafeina activeaz\u0103 o enzim\u0103 numit\u0103 AMPK, care func\u0163ioneaz\u0103 ca un fel de indicator de combustibil pentru celule. C\u00e2nd celulele au energie sc\u0103zut\u0103, AMPK intervine s\u0103 le ajute s\u0103 fac\u0103 fa\u0163\u0103 mai bine.<\/p>\n
\n\u201eC\u00e2nd celulele tale au un nivel sc\u0103zut de energie, AMPK intervine pentru a le ajuta s\u0103 fac\u0103 fa\u0163\u0103, iar, conform rezultatelor noastre, cafeina ajut\u0103 la activarea acestui mecanism”, explic\u0103 geneticianul Charalampos Rallis, potrivit Science Alert.<\/p>\n
\nPrin aceast\u0103 enzim\u0103, cafeina influen\u0163eaz\u0103 un alt comutator biologic numit TOR, care controleaz\u0103 cre\u015fterea celulelor. Astfel, celulele cresc mai bine, \u00ee\u015fi repar\u0103 ADN-ul mai eficient \u015fi rezist\u0103 mai bine la stres.<\/p>\n
\nInteresant este c\u0103 metformina, medicamentul pentru diabet care este studiat pentru efectele anti-\u00eemb\u0103tr\u00e2nire, func\u0163ioneaz\u0103 prin acela\u015fi mecanism AMPK. Asta sugereaz\u0103 c\u0103 medicamentele pe baz\u0103 de cafein\u0103 ar putea avea efecte similare \u00een viitor.<\/p>\n
\nCercet\u0103torii avertizeaz\u0103 c\u0103 studiul a fost f\u0103cut pe celule de drojdie, nu pe oameni, a\u015fa c\u0103 orice tratament medical este \u00eenc\u0103 departe de realizare.<\/p>\n
\nTotu\u015fi, descoperirea se aliniaz\u0103 cu alte studii care arat\u0103 efectele pozitive ale cafelei: de la pierderea gr\u0103simii corporale la protec\u0163ia \u00eempotriva bolilor de inim\u0103 \u015fi demen\u0163ei.<\/p>\n
