We are interested in the mechanisms of signal transduction of neuropeptides and peptide hormones, mechanisms of receptor regulation, and the role of receptor regulation in health and disease. The major peptide of interest is the neurotransmitter substance P which is involved in gastrointestinal tract regulation, pain pathways, inflammation, and central nervous system functions. Our major focus is at the level of the receptors for this peptide. We are currently studying mechanisms of substance P receptor desensitization, resensitization, and downregulation in model cell systems and using analysis of substance P-induced endocytosis of the substance P receptor to reveal mechanisms of pain transmission and inflammation in vivo in animal models. The approaches used to investigate questions of interest are pharmacological, cellular, biochemical, and molecular.
