摘要： The invention provides a method for obtaining a broadly neutralizing antibody (bNab), including screening memory B cell cultures from a donor PBMC sample for neutralization activity against a plurality of HIV-1 species, cloning a memory B cell that exhibits broad neutralization activity; and rescuing a monoclonal antibody from that memory B cell culture. The resultant monoclonal antibodies may be characterized by their ability to selectively bind epitopes from the Env proteins in native or monomeric form, as well as to inhibit infection of HIV-1 species from a plurality of clades. Compositions containing human monoclonal anti-HIV antibodies used for prophylaxis, diagnosis and treatment of HIV infection are provided. Methods for generating such antibodies by immunization using epitopes from conserved regions within the variable loops of gp120 are provided. Immunogens for generating anti-HIV1 bNAbs are also provided. Furthermore, methods for vaccination using suitable epitopes are provided.

摘要： The present invention is directed to a bacterial delivery system for delivering alphavirus replicon DNA into an animal or animal cells with the replicon encoding one or more heterologous genes to be expressed in the animal or the animal cells. The bacteria are invasive bacteria or attenuated invasive bacteria engineered to contain a DNA vector that encodes the alphavirus replicon in a eukaryotic expression cassette. The heterologous gene can encode an antigen, a therapeutic agent, an immunoregulatory agent, an anti-sense RNA, a catalytic RNA, a protein, a peptide, an antibody or an antigen-binding fragment of an antibody. In a preferred embodiment, the heterologous gene encodes one or more antigens useful as a vaccine for HIV. In addition to the bacterial delivery system, the invention provides methods of introducing and expressing the heterologous gene(s) in animal or animal cells and methods of stimulating or inducing an immune response.
