IL-2 TRANSMEMBRANE CONSTRUCTS |
摘要 |
Compounds, genetic constructs, and cancer treatment methods 035 provided. Expression vectors were designed to express fusion genes including hIL-2 with 0 FcT-< transmembrane anchor derived from 0 subunit of the FC epsilon receptor. mRN 0nd the IL2tm fusion protein was expressed in transfected RD995 tumor cells. Expression of the IL2tm protein on the tumor A511 surface membrane was confirmed by microscopy. RD995 ce11s transfected with IL-2tm or pCMV2b (empty expression vector) were implanted subcutaneously into !3 /HEN mice. Tumors in groups of mice implanted with 10<6> or 10<5> RD995 ce11s transfected with IL-2tm grew slower than controls. Without being limited to any one theory, it is believed that selective expression >f cytokines such as IL-2 on the surface >f tumors is likely to stimulate tumor-infiltrating lymphocytes that are primed and already recognize tumor antigens, enhancing tumor recognition 0nd killing, potentially avoiding toxicity associated with known cytokine therapies. |
