A SMART(er) Way to Track Influenza

Brown University researchers have created a reliable and fast flu-detection test that can be carried in a first-aid kit. The novel prototype device isolates influenza RNA using a combination of magnetics and microfluidics, then amplifies and detects probes bound to the RNA. The technology could lead to real-time tracking of influenza. Results are published in the Journal of Molecular Diagnostics.

PROVIDENCE, R.I. [Brown University] — In April 2009, the world took notice as reports surfaced of a virus in Mexico that had mutated from pigs and was being passed from human to human. The H1N1 “swine flu,” as the virus was named, circulated worldwide, killing more than 18,000 people, according to the World Health Organization. The Centers for Disease Control and Prevention in the United States said it was the first global pandemic in more than four decades. (more…)

Powerful New Approach to Attack Flu Virus

EAST LANSING, Mich. — An international research team has manufactured a new protein that can combat deadly flu epidemics.

The paper, featured on the cover of the current issue of Nature Biotechnology, demonstrates ways to use manufactured genes as antivirals, which disable key functions of the flu virus, said Tim Whitehead, assistant professor of chemical engineering and materials science at Michigan State University.

“Our most potent design has proven effective on the vulnerable sites on many pandemic influenza viruses, including several H1N1 (Spanish flu, Swine flu) and H5N1 (Avian flu) subtypes,” said Whitehead, the paper’s co-lead author. “These new therapeutics are urgently needed, so we were especially pleased to see that it neutralizes H1N1 viruses with potency.” (more…)

The Gene That Can Transform Mild Influenza in to a Life Threatening Disease

A genetic finding could help to explain why influenza becomes a life-threatening disease for some people, and yet has only a mild effect on others. Collaborative research led by scientists at UCL and the Wellcome Trust Sanger Institute found that people who carry a particular variant of the IFITM3 gene are significantly more likely to be hospitalised when they fall ill with influenza than those who carry other variants.

The gene plays a critical role in protecting the body against infection with influenza and a rare version of it appears to make people more susceptible to severe forms of the disease. The results are published in the journal Nature. (more…)

UCLA Scientists Find H1N1 Flu Virus Prevalent in Animals in Africa

UCLA life scientists and their colleagues have discovered the first evidence of the H1N1 virus in animals in Africa. In one village in northern Cameroon, a staggering 89 percent of the pigs studied had been exposed to the H1N1 virus, commonly known as the swine flu.

“I was amazed that virtually every pig in this village was exposed,” said Thomas B. Smith, director of UCLA’s Center for Tropical Research and the senior author of the research. “Africa is ground zero for a new pandemic. Many people are in poor health there, and disease can spread very rapidly without authorities knowing about it.” (more…)
