RSV IMMUNOGENS, ANTIBODIES AND COMPOSITIONS THEREOF

摘要

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. Also disclosed are methods of using the disclosed immunogens, for example to protect individuals from RSV infection. Also disclosed are methods of using the disclosed antibody proteins, for example to protect individuals from RSV infection.
