Abstract: The present invention provides polypeptides and compositions thereof for treating or limiting respiratory syncytial virus infection, and computational methods for designing such polypeptides.

Abstract: The present application relates to immunogens of broadly neutralizing monoclonal antibodies specific for HIV-1, such as broad and potent neutralizing monoclonal antibodies specific for HIV-1 and their gernation and methods of use. Broad neutralization suggests that the antibodies can neutralize HIV-1 isolates from different individuals. Immunogens or vaccines which may elicit such antibody associated responses are useful in pharmaceutical compositions for the prevention and treatment of HIV, and for the diagnosis and monitoring of HIV infection.

Abstract: The present invention provides immunogens that protect against RSV infection. The present invention also provides antibody proteins that protect against RSV infection. Such immunogens and antibody proteins are produced based on three-dimensional models also included in the invention. One model is of a complex between motavizumab and its antibody-binding domain on RSV fusion (F) protein. A second model is of a complex between 10 IF antibody and its antibody-binding domain on RSV F protein. The immunogens disclosed herein have been modified to elicit a humoral response against RSV F protein without eliciting a significant cell-mediated response against RSV. Such immunogens can comprise a scaffold into which RSV contact residues are embedded. The present invention also includes methods that utilize the disclosed three-dimensional models to produce immunogens and antibody proteins of the present invention.
