Antibiotics aren’t supposed to be effective against viruses, but new evidence in mice suggests they may help fight norovirus, a highly contagious virus that causes severe gastrointestinal illness, scientists at the School of Medicine report.
Julia Warren and colleagues at the School of Medicine have developed an approach to creating treatments for osteoporosis and autoimmune diseases that may avoid the risk of infection and cancer posed by some current medications. Warren is pictured with her mentor and co-author, Steven Teitelbaum, MD.
The Ebola virus, in the midst of its biggest outbreak on record, is a master at evading the body’s immune system. But researchers at the School of Medicine and elsewhere have learned one way the virus dodges the body’s antiviral defenses, providing important insight that could lead to new therapies.
Signals from the immune system that help repel a common parasite inadvertently can cause a dormant viral infection to become active again, a new study from the School of Medicine shows. Pictured is a helminth parasite.
Scientists have identified a new way that some viruses protect themselves from the immune system’s efforts to stop infections, a finding that may make new approaches to treating viral infections possible.
After defeating an infection, the immune system creates a memory of the attacker to make it easier to eliminate in the future. Researchers at Washington University School of Medicine in St. Louis have discovered an important component of the immune system’s strategy for preserving such immunological memories.
HIV infection or the treatments used to control it are prematurely aging the brain, researchers at Washington University School of Medicine in St. Louis and the University of California-San Diego have found. Blood flow in the brains of HIV patients is reduced to levels normally seen in uninfected patients 15 to 20 years older.
