Penn Senior Barbara Biney Is Unlocking the Genetic Secrets of Heartworm-resistant Mosquitoes
By Erica AndersenCertain mosquitoes don’t get heartworm, and Barbara Biney was keen to find out why.
Taking Blood Using ‘Push-Pull’ Method Gets Accurate Results With Fewer Pokes, Penn Study Shows
A new study by University of Pennsylvania veterinary researchers has found that blood samples collected from an intravenous catheter using a special “mixing” technique are as accurate as those collected via venipuncture, in which a needle is used to access the vein directly.
Slowing the spread of an insidious cancer
Cancer of the pancreas is rare, but deadly. Research from Penn Vet may slow its spread.
Targeting enzyme in ‘normal’ cells may impede pancreatic cancer’s spread, Penn Vet team shows
Cancer of the pancreas is a deadly disease, with a median survival time of less than six months. Only one in 20 people with pancreatic cancer survives five years past the diagnosis. The reason is the cancer’s insidiousness; tumor cells hide deep inside the body, betraying no symptoms until late in the disease, when the cancer has almost invariably spread to other organs.
Penn Study Shows How Female Immune Cells Keep Their Second X Chromosome Shut Off
Autoimmune diseases tend to strike women more than men and having multiple X chromosomes could be the main reason why. While a process called X chromosome inactivation serves to balance out gene dosage between males and females, some genes on the “inactive X” chromosome in immune cells can sometimes escape this process, giving women an extra dose of immunity-related gene expression.
Penn Team Shows How Seemingly Acute Viral Infections Can Persist
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.
Confronted With Bacteria, Infected Cells Die So Others Can Live, Penn Study Finds
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.
Celebrating five years of working dogs at Penn
Celebrating five years of working dogs at Penn
The Working Dog Center began with just a few puppies, and now, five years later, has trained some of the best noses in the business. Canine graduates have gone on to police work, search and rescue, and explosives, narcotics, and diabetes detection.
Successful Guide Dogs Have ‘Tough Love’ Moms, Penn Study Finds
Much has been written of the pitfalls of being a helicopter parent, one who insulates children from adversity rather than encouraging their independence.
Penn Vet Researchers Contribute Expertise to Checklist for ‘One Health’ Studies
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.

Dog respiratory illness map update: Mystery disease spreads to more states
Deborah Silverstein of the School of Veterinary Medicine says that the dogs most at risk for respiratory illness are those with low immunity, such as young puppies, the unvaccinated, or older dogs, and potentially short-nosed breeds.
