autologous anti-gp100:154-162 T-cell receptor gene-engineered peripheral blood lymphocytes
Human autologous peripheral blood lymphocytes (PBLs) transduced with a glycoprotein 100 (gp100) epitope-determined T cell receptor (TCR) gene, with potential antineoplastic activity. PBLs are isolated from a melanoma patient and pulsed with a viral vector encoding the TCR specific for amino acid residues154-162 of gp100 (KTWGQYWQV). After expansion ex vivo, the transduced autologous PBLs, expressing this specific TCR, are reintroduced into the patient and bind to melanoma cells expressing the gp100 protein, which may result in specific cytotoxic T-lymphocyte (CTL) killing of gp100-expressing melanoma cells. gp100 is a melanocyte lineage-specific antigen overexpressed in melanomas. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
