Cell-Based Anti-Cancer Compositions With Reduced Toxicity And Methods Of Making And Using The Same

摘要

Isolated pluralities of T cells which recognize at least one epitope of an intestinal cancer antigen or CNS cancer antigen and pharmaceutical compositions comprising the same are disclosed. Methods of making a plurality of T cells that recognize at least one epitope of an intestinal cancer antigen or CNS cancer antigen are also disclosed. Methods of treating an individual who has been diagnosed with cancer of a mucosal tissue or preventing such cancer in an individual at elevated risk are disclosed as are nucleic acid molecules that comprise a nucleotide sequence that encode proteins that recognize at least one epitope of an intestinal cancer antigen or CNS cancer antigen and T cells comprising such nucleic acid molecules.

主权项

1. An isolated plurality of T cells selected from the group consisting of:
a plurality of T cells which recognize at least one epitope of an intestinal cancer antigen and which are modified to inhibit expression or activity of one or more proteins selected from the group consisting of: α4β7 integrin and chemokine receptor 9 (CCR9); a plurality of T cells which recognize at least one epitope of a CNS cancer antigen and which are modified to inhibit expression or activity of one or more proteins selected from the group consisting of: α4β7 integrin and chemokine receptor 9 (CCR9); a plurality of T cells which recognize at least one epitope of an antigen associated with cell of the central nervous system (CNS) and which are modified to inhibit expression or activity of α4 integrins.
