Understanding how inflammation affects the immune environment in tumors

Official title: Investigating the Genesis of Tumor Immune Microenvironment (TIME) as a function of Inflammation

Funded at University of California, San Francisco · NIH-10993625 · Data updated 2026-11-12

This study is looking at how inflammation affects certain types of breast cancer that don’t have T cells, called 'cold' tumors, to find out why they develop and how treatments like aspirin might help improve responses to immunotherapy for patients.

Who could benefit from this research

Could help

Ideal candidates for this research include breast cancer patients, particularly those with cold tumors or those experiencing chronic inflammation due to conditions like obesity or aging.

Less likely to help

Patients with tumors that are already responsive to immunotherapy or those without significant inflammation may not benefit from this research.

What this research studies

This research investigates how inflammation influences the immune microenvironment in breast cancer, particularly focusing on tumors that lack T cells, known as 'cold' tumors. The study aims to identify the factors that lead to the development of these cold tumors, which are associated with poor treatment outcomes. By using a specific mouse model, researchers will explore the role of systemic inflammation and the effects of treatments like aspirin on tumor development. The goal is to uncover mechanisms that could improve immunotherapy responses in breast cancer patients.

Why it matters

Potential benefit: If successful, this research could lead to new strategies for enhancing the effectiveness of immunotherapy in breast cancer patients.

How similar studies have gone: Previous research has shown promising results in understanding the immune microenvironment in tumors, but this specific approach to linking inflammation and tumor immunity is relatively novel.
