We study osteoimmunology, an interdisciplinary field linking bone biology and immune system, with a focus on the inflammatory regulation of gene expression and signaling in osteoclastogenesis, adipogenesis, skeletal damage and repair involved in diseases, such as osteoporosis and inflammatory arthritis. We utilize genetic approaches (knockout and transgenic mice), a combination of molecular and cellular methods, various next-generation sequencing techniques, multi-omics approaches, and disease models, such as osteoporosis, inflammatory arthritis and high fat diet-induced obesity/type 2 diabetes mouse models. We have worked extensively on signal transduction and crosstalk, genetic and epigenetic regulation of gene expression, cell differentiation and in vivo bone remodeling and metabolism. We have published work at Nature Medicine, Journal of Experimental Medicine, Journal of Clinical Investigation, Journal of Immunology, eLife, and Nature Communications.
Bone destruction is a severe consequence of many skeletal diseases, including the common but refractory diseases, inflammatory arthritis and osteoporosis, and is a major cause of morbidity and disability in rheumatoid arthritis (RA) patients. Our long term goals are to identify and understand the mechanisms that regulate bone remodeling in inflammatory settings, and to develop new therapeutic approaches to suppress pathological bone resorption, recover bone formation and repair skeletal damage based on our discoveries of pathogenic mechanisms and drug targets.
Identification of distinct molecular mechanisms between inflammatory and physiological osteoclastogenesis
Regulation of inflammatory bone remodeling by:
