PHOTO: EAST NEWS/BSIP Recherche d'un vaccin contre le sida. Repr??sentation d'une des recherches pour un vaccin contre le sida. Ce vaccin ?. ADN protA?ge les souris contre le virus. Le principe consiste ?. injecter dans un macrophage de souris des boucles d'ADN contenant les informations pour fabriquer des morceaux de virus (exemple : le harpon lui permettant de se fixer ?. la cellule h??te). Ces morceaux de virus sont pr??sent??s aux lymphocytes T CD4. Activ??s, ces lymphocytes d??clenchent la r??action immunitaire afin d'obtenir des lymphocytes T CD8 m??moires et des quelques anticorps sp??cifiques permettant de d??truire les morceaux de virus s??lectionn??s dans la boucle d'ADN. Research into an AIDS vaccine. Illustration of one type of research into an AIDS vaccine. This DNA vaccine protects mice from the virus. The method: DNA strands containing the information for producing fragments of the virus (ex. the harpoon enabling it to latch on to a host cell) are injected into a mouse microphage. These virus segments are presented to the T CD4 lymphocytes which, activated, trigger an immune response which produces memory T CD8 lymphocytes and a few specific antibodies making it possible to destroy the selected virus segments in the DNA strands.
