Research from Novartis broadens understanding of HIV/AIDS
May 13th, 2009
According to recent research from the United States, "Human immunodeficiency virus type 1 (HIV-1) entry into host cells is mediated by the trimeric envelope glycoprotein complex (Env). Accordingly, the Env proteins are the targets for neutralizing antibodies (NAbs) and are the focus of Vaccines intended to induce NAbs." "Because the Env complex is labile, soluble recombinant Env (gp140) trimers require engineering to stabilize them sufficiently for use as immunogens. Trimeric forms of gp140 trimers can be created that are either cleavage-competent or cleavage-defective at the junction between the gp120 and gp41 subunits. As functional trimers are cleaved at this site,...
