Scientists working to develop a vaccine for the human immunodeficiency virus (HIV) report they have created the first antigen that induces protective antibodies capable of blocking infection of human cells by genetically-diverse strains of HIV. The new antigen differs from previously-tested vaccines by virtue of its chemically-activated property that enables close sharing of electrons and produces strong covalent bonding. Researchers used a mouse model to generate the antibodies. The report by researchers at The University of Texas Health Science Centre at Houston is online and will appear in a print issue of the Journal of Biological Chemistry in November...
