Study reveals how Ebola blocks immune system

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.

Trick that aids viral infection is identified

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.

Immune system memory cells have trick for self preservation

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 prematurely ages the brain

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.
