NCIt synonyms : Autologous Drug-resistant Gamma-delta T Cells; Autologous DRI Modified Gamma Delta T Cells; Autologous Modified Gamma Delta T-cells;
NCIt definition : A preparation of genetically modified autologous gamma delta T-lymphocytes transduced
with a lentiviral vector to encode a DNA repair enzyme, with potential immunomodulating
and antineoplastic activities. Upon administration, the autologous gene-modified gamma
delta T-cells secrete interferon-gamma (IFN-g) and exert direct killing of tumor cells.
In addition, these cells activate the immune system to exert a cytotoxic T-lymphocyte
(CTL) response against tumor cells. Gamma delta T-lymphocytes play a key role in the
activation of the immune system and do not require major histocompatibility complex
(MHC)-mediated antigen presentation to exert their cytotoxic effect. The transduction
of gamma delta T-cells may confer resistance to alkylating chemotherapeutic agents
including temozolomide and allow the use of gamma delta T-cells as an adjunct to these
agents.;
