How Sirt6 controls T cells' energy use and cancer-fighting power

Epigenetic Regulation of T Cell Metabolism and Immune Functions by Sirt6

['FUNDING_R21'] · MAYO CLINIC JACKSONVILLE · NIH-11249202

This project tests whether blocking a protein called Sirt6 can boost T cells' energy and help cancer immunotherapies work better for people with tumors.

What this research studies

Researchers are studying how Sirt6, a protein that changes gene activity, controls the fuel use of T cells that fight cancer. They will use mouse tumor models and lab-grown T cells to see how altering Sirt6 affects genes that drive glycolysis and T cell effector functions. The team will test whether blocking Sirt6 increases T cell metabolic fitness and improves their ability to attack tumors within the nutrient-poor tumor microenvironment. Results could point toward new ways to strengthen immunotherapy for patients whose T cells are metabolically suppressed.

Who could benefit from this research

Good fit: Patients with solid tumors—particularly those not responding to current immunotherapies—would be the most likely candidates for future therapies developed from this work.

Not a fit: Because this is preclinical research, it will not provide immediate treatment benefits and patients whose cancers are not driven by T cell responses may not benefit.

Why it matters

Potential benefit: If successful, this work could lead to treatments that make patients' T cells more metabolically fit and improve responses to cancer immunotherapy.

How similar studies have performed: Modulating T cell metabolism has improved anti-tumor responses in prior animal studies, while targeting Sirt6 specifically is a relatively new and less-tested strategy.
