Use of chimeric antigen receptor modified cells to treat cancer
The present disclosure relates to compositions and methods for compositions, methods, and kits for treating cancer using chimeric antigen receptor (CAR) modified cells. Some embodiments of the present disclosure relate to an isolated nucleic acid sequence encoding CAR. The CAR may include an antigen binding domain, a transmembrane domain, a costimulatory signaling region, and a CD3 zeta signaling domain. The antigen binding domain may bind to an antigen of a non-essential organ.
1. A method of stimulating a T cell-mediated immune response and treating colorectal cancer in a human patient, the method comprising:
contacting a population of cells comprising guanylate cyclase 2C (GUCY2C) comprising the amino acid sequence of SEQ ID NO: 33, in a human patient with a population of modified T cells comprising a chimeric antigen receptor (CAR),
and stimulating a T cell-mediated immune response and treating colorectal cancer in a human patient,
wherein the CAR comprises an extracellular domain, a transmembrane domain, and an intracellular domain, the extracellular domain comprising the amino acid sequences SEQ ID NO: 14.
2. The method of claim 1 , wherein the intracellular domain comprises a CD3 zeta signaling domain.
3. The method of claim 1 , wherein the intracellular domain further comprises a costimulatory signaling region comprising an intracellular domain of a costimulatory molecule selected from the group consisting of CD27, CD28, 4-1BB, OX40, CD30, CD40, PD-1, ICOS, lymphocyte function-associated antigen-1 (LFA-1), CD2, CD7, LIGHT, NKG2C, B7-H3, and any combination thereof.
4. The method of claim 1 , wherein the T cell-mediated immune response comprises release of one or more cytokines comprising IFNy.
5. The method of claim 1 , wherein the modified T cells comprise natural killer T cells.
6. The method of claim 1 , wherein the modified T cells comprise cytotoxic T lymphocytes.
7. The method of claim 1 , wherein the modified T cells comprise regulatory T cells.
8. The method of claim 1 , wherein the modified T cells comprise human T cells.
9. The method of claim 1 , wherein the modified T cells comprise a polynucleotide encoding SEQ ID NO: 40.
