GENETICALLY ENGINEERED T CELLS HAVING IMPROVED PERSISTENCE IN CULTURE

Abstract:

A T cell bank comprising genetically engineered T cells having one or more of the following features as compared to the non-engineered T cell counterparts: (a) enhanced expansion capacity in culture, (b) enhanced proliferation capacity, (c) reduced apoptosis, and (d) enhanced activation frequencies. Such genetically engineered T cells may comprise (i) a mutated gene involved in cell self-renewal; (ii) a disrupted gene involved in apoptosis; (iii) a disrupted gene involved in regulation of T cell exhaustion; or (iv) a combination of any one of (i)-(iii).
