My background is in proteomics/biochemistry and, more recently, in regulation of T cells in inflammatory and autoimmune diseases. My current research project is focused on ACP5 gene mutations that lead to inactivation of tartrate resistant acid phosphatase (TRAP) and the disease called spondyloenchondrodysplasia (SPENCD). Previous studies highlighted SPENCD as a rare Mendelian cause of human lupus and have revealed a unrecognized link between TRAP, Osteopontin (OPN) and type I interferon (IFN-α) metabolism in autoimmune disease. My research aim is to elucidate the detailed cellular pathways linking these molecules, and to understand how a loss of TRAP activity leads to human systemic lupus erythematosus (SLE).
