NCI Drug Dictionary


FAP-specific CD8-positive T cells 
A preparation of CD8-positive T cells specific for human fibroblast activating protein (FAP) with potential immunopotentiating activity. T cells have been genetically modified to express a chimeric antigen receptor specific for FAP. Upon infusion, the FAP-specific CD8-positive T cells bind to FAP-expressing tumor cells and exhibit a selective toxicity to tumor cells. This may result in both tumor cell lysis and inhibition of tumor cell growth. FAP, a cell surface glycoprotein, is overexpressed on tumor-associated fibroblasts but minimally expressed on normal, healthy cells. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
