Abstract

Disclosed is a method of directing a cellular response in a mammal by expressing in a cell of the mammal a chimeric receptor which causes the cells to specifically recognize and destroy an infective agent, a cell infected with an infective agent, a tumor or cancerous cell, or an autoimmune-generated cell. The chimeric receptor includes an extracellular portion which is capable of specifically recognizing and binding the target cell or target infective agent, and (b) an intracellular portion of a protein-tyrosine kinase which is capable of signalling the therapeutic cell to destroy a receptor-bound target cell or a receptor-bound target infective agent. Also disclosed are cells which express the chimeric receptors and DNA encoding the chimeric receptors.
