NCIt definition : Autologous prostate specific membrane antigen (PSMA) gene-modified T lymphocytes with
potential antineoplastic activity. Human autologous T-lymphocytes are isolated and
transduced ex vivo with a retrovirus encoding a chimeric immune receptor (CIR) consisting
of an antibody fragment against PSMA fused with signaling domains of the T cell. Upon
reintroduction into the patient, autologous anti-PSMA gene-modified T-cells bind to
PSMA-expressing prostate cancer cells, which may result in specific cytotoxic T-lymphocyte
(CTL) tumor cell killing.;
