Cytotoxic CD8(+) T cells play a critical role in controlling herpes simplex virus (HSV) infection and reactivation. However, little is known about the spatiotemporal dynamics of CD8(+) T cells during HSV lesion evolution or about their involvement in immune surveillance after lesion resolution. Using quantum dot-conjugated peptide-major histocompatibility(More)
BACKGROUND Adoptive T cell therapy involving the use of ex vivo generated antigen-specific cytotoxic T lymphocytes provides a promising approach to immunotherapy. It has become increasingly apparent that anti-tumor efficacy using adoptively transferred T cells is linked to their duration of in vivo persistence and can only be achieved when combined with(More)
BACKGROUND Adoptive T cell therapy represents an attractive modality for the treatment of patients with cancer. Peripheral blood mononuclear cells have been used as a source of antigen specific T cells but the very low frequency of T cells recognizing commonly expressed antigens such as NY-ESO-1 limit the applicability of this approach to other solid(More)
BACKGROUND SIV and HIV predominantly replicate in lymphoid tissue, but the study of virus specific CD8+ T cells in intact lymphoid tissue is difficult, as traditional in situ tetramer staining requires fresh tissue. RESULTS In this report, we demonstrate a novel technique using Qdot 655-conjugated peptide-MHC multimers to directly visualize SIV specific(More)
