Resistance to Immunotherapy in Patients with Urothelial Bladder Cancer Is Traced to Specific Sets of Immune Cells
NEW YORK, April 9, 2021 /PRNewswire-PRWeb/ -- Sets of genes associated with resistance to immunotherapy in patients with metastatic urothelial cancer of the bladder have been identified and validated by researchers at Mount Sinai.
- NEW YORK, April 9, 2021 /PRNewswire-PRWeb/ -- Sets of genes associated with resistance to immunotherapy in patients with metastatic urothelial cancer of the bladder have been identified and validated by researchers at Mount Sinai.
- The researchers then identified specific cells in the tumor microenvironment associated with resistance to immune checkpoint blockade, and potential targets for therapies designed to overcome resistance.
- The research is among the first to use both bulk and single-cell RNA sequencing of human bladder tumors to study resistance to immunotherapy.
- "Our research shows that a specific cellular state of myeloid cells underlying pro-tumorigenic inflammation account for resistance to immune checkpoint blockade in a very large percentage of patients with urothelial bladder cancer," Dr. Galsky says.
