  • Patent number: 8568734
    Abstract: Fusion proteins comprising CD4 minimal modules that bind to HIV Env polypeptides in a non-CD4 backbone are described. Also described are complexes of these fusion proteins with Env as well as methods of diagnosis, treatment and prevention using the polynucleotides and polypeptides are also provided.

  • Publication number: 20120276141
    Abstract: Provided herein are small molecule CD4 mimetics effective to bind to HIV Env proteins. A CD4 mimetic of the invention, when bound to an Env protein, is effective to induce a conformational change in the Env protein such that cyptic epitopes on the Env protein are exposed. Also provided herein are related methods of identifying and using such small molecule CD4 mimetics, for example, to elicit an immune response in a subject upon administration.

  • Publication number: 20080300385
    Abstract: Complexes of HIV Env and Tat proteins are advantageous as immunogens compared to Tat or Env alone, but they may dissociate when combined with a vaccine adjuvant. To avoid dissociation, complexes of Env and Tat are stabilized by the use of covalent cross linking. The extent of cross linking is important to the binding properties of the complexes, and so is controlled to avoid the loss of Env's ability to bind specifically to CD4 and Tat's ability to bind specifically to anti-Tat monoclonal antibodies.
