Education and Training

I received my PhD in Biochemistry and Molecular Biology and did my postdoctoral training at the University of Notre Dame, Notre Dame, Indiana. I worked at the Cleveland Clinic Foundation and the Holland Laboratory of American Red Cross before joining the faculty of the University of Maryland, School of Medicine in 2004. My research program has been continuously funded and supported by the National Institute of Health. I also get research support from the Department of Defense, Arthritis Foundation, and the American Heart Association.

Research Interests

My laboratory studies specific leukocyte populations in health and disease, with a major focus on the function of integrin CD11b/CD18. We investigate the role of innate and adaptive immunity, blood coagulation, and stem cells in disease development, tissue repair and regeneration. Projects range from structure-function analysis, leukocyte trafficking, signal transduction, to mouse models of inflammatory diseases, including atherosclerosis/restenosis, stroke, rheumatoid arthritis, multiple sclerosis, and inflammatory bowel disease. We conduct protein modeling and site-directed mutagenesis to identify protein-protein interactions, generate knockout and knockin mice by CRISPR to study their functions, and design peptide inhibitors and sequence-specific antibodies to block their contribution to disease development. 

One of ongoing projects is study the molecular mechanisms that allow leukocytes to migrate within a fibrin-rich inflammatory environment (Fig. 1). We are also investigating the nature of the CD11b/CD18 ligands that confer macrophages with proinflammatory or anti-inflammatory activities, based on our novel discovery that genetic inactivation of CD11b leads to the generation of T helper 17 (Th17) cells, a major subset of pathological T cells in many inflammatory diseases (Fig. 2), and the failure to develop immune tolerance in mice (J. Exp. Med, 2007). Our observation has been confirmed independently by many laboratories and further validated by genome wide association study (GWAS) in human patients where a loss of function variant of CD11b is genetically linked to increased risks of systemic lupus erythematosus (SLE).

In addition, we are investigating the role of inflammatory vs. resident macrophages (Fig. 3) in the pathogenesis of various cardiovascular and inflammatory diseases, including atherosclerosis and multiple sclerosis. For example, we reported recently that CD11b on microglia (resident macrophages in the brain) is key to the opening of the blood brain barrier following ischemic stroke (Fig. 4). Finally, we are studying the role of different stem cells, especially mesenchymal stem cells, in tissue repair and regeneration (Fig. 5). The information generated from these studies can be used to assist us in the design of therapeutic reagents that will selectively target the deleterious effects of leukocyte engagement, such as their contributions to pathogenesis of atherosclerosis, arthritis, and other autoimmune diseases, while keeping its host defense functions intact.  

Our current research interests include:

  • Structure-function studies of the CD18 integrins using CRISPR technology: integrin ligand binding in promoting and suppressing inflammation in vitro and their role in health and disease in vivo.
  • Resident vs. Inflammatory macrophages in inflammation and its resolution.
  • Aortic resident macrophages and their role in atherosclerosis.
  • Microglia in the progression and remission of progressive multple sclerosis.
  • Messenchyml stem cells of different embryonic origins in bone repair and regeneration.
