The transgene expresses TVA, the receptor for avian retrovirus ALV, subgroup A (ALV-A), from a quail cDNA under control of a modified human nestin promoter that includes the second-intron enhancer - which in adult mice directs expression specifically in early glial progenitor cells - and the herpes simplex virus thymidine kinase (HSV-TK) promoter. Cells presenting this receptor can be infected by replication-competent ALV splice acceptor (RCAS) vectors, permitting cell type specific expression of vector-borne genes. (J:52161)
