Research Summary

The focus of our lab is to characterize the role of immune cells called macrophages in tumor progression. The focus of these studies has been to identify pathways of tumorigenesis critical to a variety of murine tumor types including lung carcinoma, melanoma, colon carcinoma and cutaneous squamous cell carcinoma. In addition, we are performing parallel studies in identifying tumor-promoting pathways produced by infiltrating macrophages in human squamous cell carcinomas from immunosuppressed transplant recipients vs non-immunosuppressed patients.
