Mainly focus on the role of stromal cells in secondary lymphoid organ (SLO) development and their roles in infectious immunity in mouse models. Recent studies have been focused on 1) delineating the role of alternative NF-κB signaling on stromal cells in SLO development and function; 2) exploring the biological consequences of alternative NF-κB pathway on stromal cells in the homeostasis of intestinal immunity; 3) determining the role of LTbR signaling on stromal cells in tumor metastasis.
