I am working on the role of CD13/Aminopeptidase N in Rheumatoid Arthritis (RA). Specifically I measure the amount and activity of CD13 in biological samples from RA individuals. I look at the localization of CD13 on fibroblast like synoviocytes (FLS) both cellular and extracellular. I’m also working to determine how CD13 (normally a cell surface molecule) becomes soluble. I also look at the regulation of CD13 by pro-inflammatory factors on RA FLS. In addition I’m exploring possible functions for CD13 in RA disease pathogenicity. My main focus is on CD13 as a pro-migratory agent for FLS and T cells. Especially how CD13 could aid T cells in entering an RA joint.
