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.

Penn Researchers Identify New Target, Develop New Drug for Cancer Therapies
September 20, 2017
Opening up a new pathway to fight cancer, researchers at the University of Pennsylvania have found a way to target an enzyme that is crucial to tumor growth while also blocking the mechanism that has made past attempts to target that enzyme resistant to treatment. Researchers were able to use this finding to develop a drug that successfully inhibits tumor growth of melanoma as well as pancreatic and colorectal cancer in mice. The journal Cancer Discovery published the findings online this month.
