Abstract: Disclosed herein are methods, systems, compositions and strategies for the creation and use WW-domain-Activated Extracellular Vesicles (WAEVs) for presenting HIV antigen domains. These WAEVs can be harnessed to deliver and present HIV antigens useful for vaccine development. Specifically, the disclosure provides a fusion protein comprising: (a) a WW-containing domain; (b) a transmembrane domain; and (c) an extracellular domain, wherein the extracellular domain is an HIV antigen domain. Further provided are sequences of each domain as well as methods of producing and using the fusion protein.

Abstract: Isolated immunogens including a HIV-1 gp120 polypeptide or immunogenic fragment thereof stabilized in a CD4 bound confirmation by crosslinked cysteines, and methods of their use are disclosed. The immunogens are useful, for example, for generating an immune response to HIV-1 gp120 in a subject.
