GP100-specific T cell receptors and related materials and methods of use
View Patent ↗The invention provides human cells, particularly human T cells, comprising a murine T Cell Receptor (TCR) having antigen specificity for the cancer antigen gp100. Isolated or purified TCRs having antigenic specificity for amino acids 154-162 of gp100 (SEQ ID NO: 1), as well as related polypeptides, proteins, nucleic acids, recombinant expression vectors, host cells, populations of cells, antibodies, or antigen binding fragments thereof, conjugates, and pharmaceutical compositions, are further provided. The invention further provides a method of detecting the presence of cancer in a host and a method of treating or preventing cancer in a host comprising the use of the inventive materials described herein.
1. A human cell comprising a murine T Cell Receptor (TCR) comprising one or more of the amino acid sequences selected from the group consisting of SEQ ID NOs: 2 to 9.
2. The human cell of claim 1 , wherein the cell is a T cell.
3. The human cell of claim 1 , wherein the TCR has antigenic specificity for amino acids 154-162 of human gp100 SEQ ID NO: 1.
4. The human cell of claim 1 , wherein the TCR comprises an amino acid sequence selected from the group consisting of SEQ ID NOs: 10 to 17.
5. The human cell of claim 1 , wherein the TCR comprises SEQ ID NO: 2 and SEQ ID NO: 3.
6. A population of cells comprising at least one human cell of claim 1 .
7. A conjugate comprising the human cell of claim 1 and a therapeutic agent, a detectable moiety, or both a therapeutic agent and a detectable moiety.
8. The conjugate of claim 7 , wherein the therapeutic agent is an anti-cancer therapeutic agent.
9. A pharmaceutical composition comprising the human cell of claim 1 , and a pharmaceutically acceptable carrier.
