Research

Leukocyte migration to the joint is a critical step in the disease pathogenesis of rheumatoid arthritis (RA). Autoreactive inflammatory cells leave the circulation and are honed to their immunologic target through a process called chemotaxis. One of my research interests focuses on the regulation of chemokine receptors (in particular CX3CR1 and CXCR4) and downstream G-protein coupled receptor kinases (GRKs) as they pertain to leukocyte migration and the development of immune-mediated diseases.

The CXCR4 chemokine receptor and its ligand CXCL12 (SDF-1) play a critical role in homeostatic leukocyte migration and development, and have been implicated in numerous immune-mediated disease processes such as cancer, HIV, rheumatoid arthritis, and immunodeficiency. Chemokine receptors are G protein coupled receptors (GPCRs) and regulated by GRKs. My lab has particular focus on the selective regulatory role of GRK3 on the CXCL12/CXCR4 signaling axis as it pertains to RA, breast cancer, and bone marrow signaling interactions.
