Lymphocyte development and its dysregulation in immune disease

Research Description

My research has been focusing on lymphocyte development and its dysregulation in autoimmune diseases. Studies in normal and mutant mice have aimed to examine lymphocyte apoptosis and its role in maintaining quality control and homeostasis in the immune system. We are also interested in studying the dysregulated cytokine production and lymphocyte function during the pathogenesis of autoimmune disorders. Using an animal model for human rheumatoid arthritis, we are developing novel strategies for targeting TNF family cytokines in treating autoimmune arthritis. Further knowledge of the regulatory mechanisms underlying lymphocyte development and function should shed light on the prophylaxis and therapy of immune diseases.

Biography

Professor LU graduated in Medicine from Jiangsu University and received his PhD from McGill University. After completing his postdoctoral research at the University of Toronto, he joined the University of Hong Kong in 2000 and is currently Professor of Immunology in the Department of Pathology.

The study of immune dysregulations in autoimmune diseases is the main focus of Professor Lu’s research. During the last ten years, his laboratory has been exploring novel strategies for the treatment of rheumatoid arthritis, a crippling disease with high social relevance in Hong Kong. His team was among the first to successfully treat autoimmune arthritis by silencing B-cell activating factor in a preclinical study, which has significant therapeutic implications for the effective treatment of rheumatoid arthritis. Professor Lu is an internationally recognised expert in the field of autoimmunity and has served as the Chairman of Hong Kong Society for Immunology. He has published over 100 peer-reviewed papers in leading immunology and rheumatology journals. His research achievements have been recognised with numerous awards including the Croucher Senior Research Fellowship in 2012 and the HKU Outstanding Researcher Award in 2013.
