1. A method of destroying an HIV-infected cell in a human, said method comprising administering to said human an effective amount of autologous cytotoxic T lymphocytes, each of said autologous cytotoxic T lymphocytes expressing a membrane-bound, proteinaceous chimeric receptor, comprising (a) an intracellular portion of a Syk protein-tyrosine kinase which is capable of signalling said autologous cytotoxic T lymphocyte to destroy a receptor-bound HIV-infected cell and (b) an extracellular portion comprising a portion of CD4 which is capable of specifically recognizing and binding said HIV-infected cell, whereby each of said autologous cytotoxic T lymphocytes is capable of specifically recognizing and destroying said HIV-infected cell. |
