Understanding how a common breast cancer drug affects immune cells

Immunometabolic pathways enabled by PARP inhibition in breast cancer

NIH-funded research Brigham and Women's Hospital · NIH-11113865

This research explores how a type of breast cancer medicine, called PARP inhibitors, can both help and hinder the body's immune response against tumors.

What this research studies

We know that PARP inhibitors, a common breast cancer treatment, can sometimes create immune cells called TAMs that actually help tumors grow and resist therapy. At the same time, these drugs can also make other immune cells, called T-cells, stronger and better at fighting cancer. This project aims to understand why PARP inhibitors have these opposite effects on different immune cells. By figuring out this puzzle, we hope to find new ways to make breast cancer treatments more effective for patients.

Who could benefit from this research

Good fit: This foundational research is relevant for breast cancer patients currently receiving or considering PARP inhibitor therapy, as well as those who might benefit from improved immune-based treatments.

Not a fit: Patients without breast cancer or those not suitable for PARP inhibitor treatment may not directly benefit from this specific research.

Why it matters

Potential benefit: If successful, this work could lead to new strategies that improve how PARP inhibitors and other immune therapies work together to fight breast cancer.

How similar studies have performed: While PARP inhibitors are established, combining them with immune checkpoint blockade has not yet shown superior results in early trials, highlighting the novelty of this approach to understand and overcome resistance.
