Targeting the CD73 protein in triple-negative breast cancer

Targeting posttranslational modifications of CD73 in TNBCs

['FUNDING_R01'] · EMORY UNIVERSITY · NIH-11303261

What this research studies

Researchers will study how the protein CD73 is controlled inside triple-negative breast cancer cells and how that control affects the immune response. They will focus on a molecule called TRIM21 that tags CD73 for breakdown and use cell co-cultures and animal models to see what happens when CD73 is stabilized or lowered. The team will measure levels of adenosine in the tumor environment and how well CD8+ T cells can expand and attack tumor cells. The goal is to find strategies that could make chemotherapy and immunotherapy work better by reducing CD73-driven immune suppression.

Who could benefit from this research

Good fit: People with triple-negative breast cancer, especially those whose tumors show high CD73 levels, would be the most relevant candidates for future related trials.

Not a fit: Patients with non–triple-negative breast cancer or tumors that do not rely on CD73-driven suppression are less likely to benefit from therapies based on this work.

Why it matters

Potential benefit: If successful, this work could lead to new treatments that lower CD73 to boost immune attack on tumors and reduce resistance to chemo and immunotherapy in triple-negative breast cancer.

How similar studies have performed: Laboratory and early clinical work targeting CD73 signaling has shown promise for improving anti-tumor immunity, but targeting the protein's regulation via TRIM21 is a newer, largely preclinical approach.
