The functions of the human cytomegalovirus (HCMV) IE86 protein are paradoxical, as it can both activate and repress viral gene expression through interaction with the promoter region. Although the mechanism for these functions is not clearly defined, it appears that a combination of direct DNA binding and protein-protein interactions is involved. Multiple(More)
B cell functional defects are associated with delayed neutralizing antibody development in pathogenic lentivirus infections. However, the timeframe for alterations in the antibody repertoire and somatic hypermutation (SHM) remains unclear. Here, we utilized the SIV/rhesus macaque (RM) model to investigate the dynamics of immunoglobulin VH gene diversity and(More)
Rhesus macaque APOBEC3A (rhA3A) is capable of restricting both simian-human immunodeficiency virus (SHIVΔvif) and human immunodeficiency virus (HIV-1Δvif) to a greater extent than hA3A. We constructed chimeric A3A proteins to define the domains required for differential lentivirus restriction. Substitution of amino acids 25-33 from rhA3A into hA3A was(More)
