Abstract

DESCRIPTION (provided by applicant): This HIT-IT proposal addresses the hypothesis that an agent designed to bind to HIV-1 envelope spike glycoprotein gp120 and insert into the viral membrane simultaneously can deliver a membrane-directed force to the spike, thereby causing it to porate its own membrane, resulting in outflow of viral contents and deactivation of the virus. This hypothesis is based on the vision that (i) the mature HIV virion is likely osmotically stressed, and (ii) one role of the viral spike glycoprotein gp41 is to destabilize the viral membrane. In this work, we will design, test and optimize chimerae with gp120-binding and membrane-insertion domains. The project relies on a highly interconnected simulation/experimentation approach. If successful, our results will form the basis upon which a completely new class of virucidal agents can be developed.
