detectează
încă din primele zile ale formării unei tumori, nu pentru a le ataca, ci pentru a le proteja. Cercetătorii francezi de la Universitatea Pierre şi Marie Curie au demonstrat pe animale de laborator cum apariţia primelor celule canceroase declanşează imediat un răspuns din partea anumitor celule imunitare, denumite „limfocite T regulatoare“. Acestea se deplasează rapid către tumoare, recunoscând în celulele canceroase moleculele care există în ţesuturile sănătoase. Apoi, celulele imunitare blochează acţiunea altor limfocite, împiedicându-le să atace şi să distrugă celulele canceroase.
