How Immune Cells Protect Against Infection and Cancer in the Abdomen

Differentiation and Function of Monocytes and Macrophages

NIH-funded research Washington University · NIH-10977054

This research looks at how special immune cells in the abdomen, called macrophages, work to fight off germs and how their loss might affect conditions like cancer.

What this research studies

This research explores how immune cells called macrophages, found in the fluid of body cavities like the abdomen, protect us from infections. When inflammation occurs, these macrophages produce a clotting factor to create a 3D environment, helping them capture microbes more effectively. Sometimes, these macrophages disappear for a while after a strong inflammatory response, potentially leaving the body vulnerable. We are studying how these cells die and repopulate, and if this period of vulnerability could contribute to the progression of diseases like ovarian cancer.

Who could benefit from this research

Good fit: This foundational research does not directly involve patient participation, but future studies building on this work might seek patients with conditions related to peritoneal infections or ovarian cancer.

Not a fit: Patients not experiencing conditions related to peritoneal immunity or ovarian cancer may not directly benefit from this specific line of research.

Why it matters

Potential benefit: If successful, this work could lead to new ways to protect against infections in body cavities and potentially inform treatments for cancers like ovarian cancer by understanding immune cell behavior.

How similar studies have performed: The specific mechanisms of macrophage disappearance and repopulation, especially their link to coagulation and cancer progression, represent a novel area of investigation.
