New tool to prevent infection after C-section
A new study from Washington University School of Medicine in St. Louis offers strong guidance on the best way to reduce the infection risk. Rather than prepping patients with iodine-alcohol — a common antiseptic combination in C-sections — the research indicates that chlorhexidine-alcohol is significantly more effective.
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.
Molecular scissors help viruses break out of cells
Scientists at the School of Medicine have produced the first detailed images of a protein important to viral infection. The images, from Phyllis Hanson, MD, PhD, and her colleagues, are of molecular scissors that let viruses such as HIV bud from infected cells.
$32 million NIH grant funds study of multipurpose infection fighter
A multi-institutional campaign to harness a newly recognized cellular defense against infection is being led by researchers at the School of Medicine. A $32 million grant from the National Institutes of Health is funding the collaborative, which could lead to drugs with unprecedented versatility in fighting different infections. Washington University’s Herbert W. Virgin IV, MD, PhD, is the principal investigator.
Some immune cells defend only one organ
School of Medicine scientists have uncovered a new way the immune system
may fight cancers and viral infections. The finding could aid efforts to
use immune cells to treat illness.
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.
Infections of West Nile virus could set U.S. record
West Nile virus expert Michael Diamond discusses the potentially record-setting 2012 West Nile virus infection season and describes ways to reduce chances of infection.
Urinary tract infections steal from hosts’ defense arsenals
Humans have known for centuries that copper is a potent weapon against infection. New research shows that the bacteria that cause serious urinary tract infections “know” this, too, and steal copper to prevent the metal from being used against them. Blocking this thievery with a drug may significantly improve patients’ chances
of fighting off infections, according to researchers.
Timing, duration of biochemical bugle call critical for fighting viruses
Researchers have identified the primary player of the
biochemical bugle call that musters the body’s defenders against viral
infection. Scientists at Washington University School of Medicine
in St. Louis have shown that a key molecule, MDA5, is essential for
producing enough interferon (the bugle call) to rally virus-fighting
cells during certain viral infections.
Seasonal flu shots begin Oct. 4 for medical school employees
Seasonal flu vaccines will be offered to School of Medicine faculty and staff at no cost beginning Oct. 4. The School of Medicine strongly recommends that all employees, even those with no direct patient contact, get a vaccine.
