The main focus of the lab is the differentiated smooth muscle cell, which forms the walls of most of the hollow organs in the body. Inappropriate contraction or relaxation of smooth muscle is responsible for a number of diseases including stroke, hypertension, heart failure, asthma and premature labor.
We have had a longstanding interest in the differentiated smooth muscle cell. We are currently focused on the vascular cells in the aorta. The proximal aorta normally functions as a critical shock absorber to prevent the full force of the heartbeat from reaching the delicate small blood vessels of the brain, kidney, and heart, where it would cause damage and lead to dementia, kidney failure and heart failure. This shock absorber function is impaired with age. Thus aortic stiffness is both an early biomarker of, and a contributor to, adverse aging-related cardiovascular outcomes. We have identified specific cytoskeletal protein-protein interfaces as being involved in aging-induced increased aortic stiffness in a mouse model. Our current efforts are focused on developing targeted potential therapeutic molecules to prevent or reverse the effects of aging on aortic stiffness and its consequent adverse cardiovascular and cognitive outcomes.

Dr. Kuldeep Singh Accepted a Research Scientist Position in India
Dr. Singh was hired as a Research Scientist in CSIR-IHBT, Palampur, India. He is leaving Boston University on August 6, 2020. Before his departure, he delivered an invited lecture on the topic “COVID-19: Epidemiology, effects on the cardiovascular system and possible treatments” in an International webinar on “Recent Trends in Medicinal Chemistry” on July 27-28, 2020 organized by Center for Basic Sciences, Pt Ravishankar Shukla University, Raipur and Chemical Research Society of India, Chhattisgarh, India. We appreciate all the amazing work he has done in the Morgan Lab. We wish him all the best in his future career.

Undergrads Emily and Anne presented their summer research at the Undergraduate Research Opportunities Program (UROP) symposium.
Emily’s project worked with the role of endosomes in regulating aortic stiffness.
Anne’s project investigated the inhibition of nonmuscle myosin with blebbistatin and its effect on aortic stiffness. Pictured below, Anne and Postdoc Kuldeep.

Hearts, Minds, and Microbubbles
The Morgan Lab, in collaboration with Dr. Tyrone Porter, is working to develop a localized drug delivery system that releases peptides directly into smooth muscle cells. The peptides are attached to microbubbles, which are guided through the bloodstream and burst using ultrasound waves, delivering the peptide. Read the article here.
