Studying immune cell trafficking and function in mucosal inflammation and cancer.


The Sumagin Lab

Our laboratory is utilizing state-of-the-art intravital imaging techniques, including multi-photon and spinning disc microscopy, as well as multiple animal models of intestinal inflammation and disease, supplemented by in-vitro biochemical and molecular approaches to study leukocyte (neutrophil, monocyte/macrophage) trafficking in mucosal tissues. We are particularly interested in exploring the roles of innate immune cells in regulating intestinal homeostasis, wound healing, host pathogen interactions and cancer development.
