a joint venture between Geron Corporation and the Biotechnology Research Corporation of Hong Kong (BRC), announced today the presentation of studies demonstrating that their small molecule telomerase activator, TAT0002, enhances the anti-viral activity of CD8 T-cells from HIV/AIDS donors against infected CD4 cells from the same donors.
Effros' team also showed that Geron's small molecule telomerase activators had similar activity enhancing the ability of certain HIV-specific CD8 T-cells to inhibit virus production when co-cultured with an HLA-matched HIV-infected CD4 T-cell line.
Recent clinical data from other WT1 peptide immunotherapeutics stimulating CD8 T-cells has been very positive.
