Five faculty members from the University of Pennsylvania have been named fellows of the American Association for the Advancement of Science.

The blood stem cells that live in bone marrow are at the top of a complex family tree. Such stem cells split and divide down various pathways that ultimately produce red cells, white cells and platelets.

Meghan Hussey, a 2012 University of Pennsylvania graduate, is one of 12 Americans selected to receive a George J. Mitchell Scholarship for graduate studies in Ireland or Northern Ireland.

The lab of Avinash Bhandoola, PhD, professor of Pathology and Laboratory Medicine, has studied the origins of T cells for many years. One protein called Notch, which has well-known roles in the development of multiple tissues, plays an essential role in triggering T-cell development.

The research of physician-scientist Katalin Susztak, MD, PhD, associate professor of Medicine in the Renal Electrolyte and Hypertension Division, at the Perelman School of Medicine, University of Pennsylvania, strives to understand the molecular roots an

Drugs that inhibit the activity of enzymes called histone deacetylases (HDACs) are being widely developed for treating cancer and other diseases, with two already on the market. Researchers at the Perelman School of Medicine, University of Pennsylvania, show that a major HDAC still functions in mice even when its enzyme activity is abolished, suggesting that the beneficial effects of HDAC inhibitors may not actually be through inhibiting HDAC activity, and thus warranting the reassessment of the molecular targets of this class of drugs.

New research presented today at the 2013 Scientific Sessions of the American Heart Association by researchers at the Perelman School of Medicine at the University of Pennsylvania found no difference in outcomes at one-year between two recommended surgical options for treating ischemic mitral regurgitation (IMR) – repair of the leaky valve or its replacem

The instructions for building all of the body’s proteins are contained in a person’s DNA, a string of chemicals that, if unwound and strung end to end, would form a sentence 3 billion letters long.

Risk of depression is lower in menopausal women after their final menstrual period (FMP) but a history of depression increases the risk of depressive symptoms both before and after menopause, according to a new study from researchers at the Perelman School of Medicine at the University of Pennsylvania.

Skin provides a first line of defense against viruses, bacteria and parasites that might otherwise make people ill. When an injury breaks that barrier, a systematic chain of molecular signaling launches to close the wound and re-establish the skin’s layer of protection.
