  • Wen lab has two different, but interconnected research focuses. One focus of the Wen lab is aimed at understanding the signaling pathways that govern proper B and T cell activation and communications and how aberrant signaling in T and B cells will lead to human diseases. The lab has studied the mechanisms by which molecules in antigen receptor signaling pathways such as: phospholipase C gamma (PLCg), B-cell lymphoma 10 (Bcl10), and molecules in cytokine signaling pathways, including Grb2-associated binding (Gab) proteins, control and modulate T and B cell development and activation and how aberrant functions of these molecules lead to lymphopenia and autoimmunity.

    Another major focus of the Wen lab is understanding the interplay between immune systems and coagulation systems in healthy and disease states. Currently, the lab is studying how antibodies regulate the function of platelets and other cells involved in the coagulation system and the prevalence, ontogeny, and activation of the host B cells that make such antibodies in healthy people and patients with heparin-induced thrombocytopenia and thrombosis (HIT) and COVID-19. Studies will be performed in both human and mouse systems using techniques of biochemistry, cell biology, molecular biology, and bioinformatics with the goal of understanding the molecular pathogenesis underlying antibody mediated thrombotic complications in HIT and COVID-19 and developing new diagnostic and therapeutic tools for these conditions.
