Dolly Mehta, PhD

PROFESSOR OF PHARMACOLOGY & INTERIM HEAD DEPARTMENT OF PHARMACOLOGY

Research Interests 

My lab investigates interactive signaling between non-phagocytic (i.e., endothelial cells) and phagocytic cells (i.e., monocytes/macrophages) in regulating tissue function. We seek to understand how stressors (such as ligands for G-protein coupled receptors or toll-like receptors) on these cell types trigger metabolic and epigenetic changes to alter tissue function under physiological setting versus pathological (i.e., cancer) settings.


Specific projects are:


1)  Investigate the non-canonical function of the tumor suppresor, PTEN, in generating a reparative and anti-inflammatory population of endothelial cells that maintain normal tissue function.  


2)  Investigate the role of focal adhesion kinase (FAK) in maintaining cellular tension and epigenetics.


3)  Determine mechanisms inducing the synthesis of GPCR, S1PR1, and how it determines physiological versus pathological angiogenesis.


4)  Investigate the role of S1P and cAMP metabolism in macrophages in dictating tissue macrophage phenotype and inflammatory function.
