Every time a hormone is released from a cell, every time a neurotransmitter leaps across a synapse to relay a message from one neuron to another, the cell must undergo exocytosis. This is the process responsible for transporting cellular contents via lipid-encapsulated vesicles to the cell surface membrane and then incorporating or secreting them through membrane fusion.

In early December, when a mother bear and her three cubs turned up dead in a church parking lot in northeast Pennsylvania, it sparked CSI-like intrigue.

J. Larry Jameson has been reappointed executive vice president of the University of Pennsylvania for the Health System and dean of Penn’s Perelman School of Medicine.

In cells, DNA is transcribed into RNAs that provide the molecular recipe for cells to make proteins. Most of the genome is transcribed into RNA, but only a small proportion of RNAs are actually from the protein-coding regions of the genome.

President Amy Gutmann and Provost Vincent Price are pleased to announce the appointment of Jay Gottfried as the University of Pennsylvania’s eighteenth Penn Integrates Knowledge University

Viruses and their hosts are in a eternal game of one-upmanship. If a host cell evolves a way to stop a virus from spreading, the virus will look for a new path. And so on and so forth.

At 7 years old, Arabella Uhry, now a junior at the University of Pennsylvania, developed a relationship that sparked her interest in health care.

Patients who had a diagnosis of Parkinson’s disease (PD) with dementia (PDD) or dementia with Lewy bodies (DLB) and had higher levels  of Alzheimer’s disease (AD) pathology in their donated post-mortem brains also had more severe symptoms of these Lewy body diseases (LBD) during their lives, compared to those whose brains had less AD pathology, according to research from the 

The value of intersecting the sequencing of individuals’ exomes (all expressed genes) or full genomes to find rare genetic variants -- on a large scale -- with their detailed electronic health record (EHR) information has “myriad benefits, including the illumination of basic human biology, the early identification of preventable and treatable illnesses, and the identification and validation of
