Purine Pharmacology:  Adenosine is an endogenous purine that regulates most physiological systems.  We are investigating (using a variety of molecular, analytical, cellular and physiological tools and using several strains of genetically modified animals, as well as conducting studies in patients): 1) the production of adenosine from 3’,5’-cAMP and 2’,3’-cAMP (the cAMP-adenosine pathways; see Figure 1); 2) the modulation of adenosine levels by guanosine;3) the roles of adenosine in regulating the sympathetic nervous system, heart, vascular system, kidneys, bladder, brain and immune system;4)  the effects of adenosine on cardiac fibroblasts, vascular smooth muscle cells, vascular endothelial cells, glomerular mesangial cells, renal epithelial cells, T cells and B cells; 5) the role of exosomes in adenosine biochemistry; 6) how to modulate the adenosine system with drugs to treat cardiovascular and renal diseases, traumatic brain injury, cancer and HIV infected patients.

Cardiovascular and Renal Pharmacology:  Our recent studies indicate that NPY1-36 (a peptide released from sympathetic nerves) and PYY1-36 (a peptide released from the intestines) trigger proliferation of and extracellular matrix production by preglomerular vascular smooth muscle cells (PGVSMCs) and glomerular mesangial cells (GMCs) in kidneys from genetically-hypertensive animals, a phenomenon mediated via Y1 receptors and that involves signaling by RACK1 (receptor for activated C kinase 1).  Dipeptidyl peptidase IV (DPPIV) metabolizes NPY1-36 and PYY1-36 (Y1 receptor agonists) to NPY3-36 and PYY3-36 (inactive at Y1 receptors).  We are investigating whether a new class of antidiabetic drugs (DPPIV inhibitors) may adversely affect the kidneys of hypertensive subjects by preventing the conversion of PYY1-36 and NPY1-36 to less active metabolites and thereby promoting inappropriate cell proliferation and extracellular matrix production (see Figure 2).
