UNLABELLED Human immunodeficiency virus (HIV) persistence in latently infected resting memory CD4+ T-cells is the major barrier to HIV cure. Cellular histone deacetylases (HDACs) are important in maintaining HIV latency and histone deacetylase inhibitors (HDACi) may reverse latency by activating HIV transcription from latently infected CD4+ T-cells. We(More)
We have mutated a conserved leucine in the putative membrane-spanning domain to serine in human GABA(A) beta2 and investigated the actions of a number of GABA(A) agonists, antagonists and modulators on human alpha1beta2deltaL259Sgamma2s compared to wild type alpha1beta2gamma2s GABA(A) receptors, expressed in Xenopus oocytes. The mutation resulted in smaller(More)
Effective immunotherapies for HIV are needed. Drug therapies are life-long with significant toxicities. Dendritic-cell based immunotherapy approaches are promising but impractical for widespread use. A simple immunotherapy, reinfusing fresh autologous blood cells exposed to overlapping SIV peptides for 1 hour ex vivo, was assessed for the control of(More)
BACKGROUND HIV infection induces chronic immune activation which is associated with accelerated disease progression; the causes of this activation, however, are incompletely understood. We investigated the activation status of CD4+ T cells specific for chronic herpes viruses and the non-persistent antigen tetanus toxoid (TT) in HIV positive and HIV negative(More)
