Using engineered macrophages to target triple-negative breast cancer

Rac-enhanced Chimeric Antigen Receptor-Macrophage (Race-CAR-M) Immunotherapy for Triple Negative Breast Cancer

NIH-funded research University of California Santa Barbara · NIH-11118486

This study is exploring a new way to treat triple-negative breast cancer by using specially modified immune cells called macrophages to better find and destroy cancer cells, which could lead to improved outcomes for patients.

What this research studies

This research focuses on developing a new immunotherapy approach for triple-negative breast cancer (TNBC) by engineering macrophages to express a Chimeric Antigen Receptor (CAR) that targets specific cancer cell antigens. The study aims to enhance the ability of these CAR-Macrophages to infiltrate tumors and effectively eliminate cancer cells. By activating a specific protein (Rac2) within these macrophages, the researchers hope to improve their tumor-targeting and phagocytic capabilities, potentially leading to better treatment outcomes for patients with TNBC.

Who could benefit from this research

Good fit: Ideal candidates for this research are patients diagnosed with triple-negative breast cancer who have limited treatment options.

Not a fit: Patients with other subtypes of breast cancer or those who do not have cancer may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could provide a novel and more effective treatment option for patients with triple-negative breast cancer.

How similar studies have performed: While CAR-T therapies have shown success in hematologic cancers, the application of CAR-M therapies in solid tumors like TNBC is still being explored and represents a novel approach.
