Penn Team Shows How Seemingly Acute Viral Infections Can Persist
October 6, 2017
Infections caused by viruses, such as respiratory syncytial virus, or RSV, measles, parainfluenza and Ebola, are typically considered acute. These viruses cause disease quickly and live within a host for a limited time. But in some cases the effects of the infection, and presence of the virus itself, can persist. RSV, for example, can lead to chronic respiratory problems, measles can lead to encephalitis and the Ebola virus can be transmitted by patients thought to be cured of the disease.
Confronted With Bacteria, Infected Cells Die So Others Can Live, Penn Study Finds
September 29, 2017
The immune system is constantly performing surveillance to detect foreign organisms that might do harm. But pathogens, for their part, have evolved a number of strategies to evade this detection, such as secreting proteins that hinder a host’s ability to mount an immune response. In a new study, a team of researchers led by Igor E. Brodsky of the University of Pennsylvania, identified a “back-up alarm” system in host cells that responds to a pathogen’s attempt to subvert the immune system. 
Successful Guide Dogs Have ‘Tough Love’ Moms, Penn Study Finds
August 7, 2017
Much has been written of the pitfalls of being a helicopter parent, one who insulates children from adversity rather than encouraging their independence. A new study from the University of Pennsylvania seems to back up this finding — in dogs. Researchers showed that doting mothers seem to handicap their puppies, in this case reducing the likelihood of successfully completing a training program to become guide dogs.
Penn Vet Researchers Contribute Expertise to Checklist for ‘One Health’ Studies
August 4, 2017
A growing body of scientific research is focused on One Health, the integration of knowledge concerning humans, animals and the environment. Yet there is no clear, unified definition of what a One Health study is or how such a study should be conducted.
A Perturbed Skin Microbiome Can Be ‘Contagious’ and Promote Inflammation, Penn Study Finds
June 29, 2017
Even in healthy individuals, the skin plays host to a menagerie of bacteria, fungi and viruses. Growing scientific evidence suggests that this lively community, collectively known as the skin microbiome, serves an important role in healing, allergies, inflammatory responses and protection from infection.
Fossil ‘Winged Serpent’ Is a New Species of Ancient Snake, Penn Doctoral Student Finds
May 10, 2017
An ancient sink hole in eastern Tennessee holds the clues to an important transitional time in the evolutionary history of snakes. Among the fossilized creatures found there, according to a new paper co-authored by a University of Pennsylvania paleontologist, is a new species of snake that lived 5 million years ago.
Penn Team Characterizes the Underlying Cause of a Form of Macular Degeneration
April 19, 2017
Named for Friedrich Best, who characterized the disease in 1905, Best disease, also known as vitelliform macular dystrophy, affects children and young adults and can cause severe declines in central vision as patients age. The disease is one in a group of conditions known as bestrophinopathies, all linked to mutations in the BEST1 gene. This gene is expressed in the retinal pigment epithelium, or RPE, a layer of cells that undergirds and nourishes photoreceptor cells, the rods and cones responsible for vision.
Look to Lactate to Help Predict Ill Cats’ Prognoses, Penn Vet Study Says
April 12, 2017
Many factors go into evaluating the prognosis of a critically ill animal, usually involving a combination of objective metrics, such as blood pressure or blood oxygenation, and more subjective clinical signs, such as alertness or lethargy.
Penn Vet Library Exhibit Explores the Human-Animal Connection Through Art
April 10, 2017
The latest exhibit from Eleanor Hubbard, an artist and University of Pennsylvania alumna, “Natural Selection: Lost Cat, Found Ox and Other Inspiring Bonds,” is on display in the School of Veterinary Medicine’s Steven W. Atwood Library through May 16.
