A vaccine consisting of irradiated human fetal lung fibroblasts (Medical Research Council 5 or MRC-5) transfected with autologous non-small cell lung cancer (NSCLC)-derived DNA with potential immunostimulatory and antineoplastic activities. Upon administration, autologous NSCLC DNA-transfected semi-allogeneic fibroblasts MRC-5 vaccine expresses NSCLC tumor-associated antigens (TAAs) in addition to MHC class I-determinants and the co-stimulatory molecule B7.1, which may induce a cytotoxic T-lymphocyte (CTL) response against NSCLC cells. The MRC-5 cell line, established in 1966, is a human diploid lung fibroblast cell line that is permissive for infection by a wide range of human viruses including human cytomegalovirus (HCMV) and coxsackie B viruses. Check for active clinical trials using this agent. (NCI Thesaurus)
