Cell-Culture And Animal Tests Show Antiviral Could Provide Protection Against HIV, Ebola, Hepatitis C, Herpes And More

The development of antibiotics gave physicians seemingly miraculous weapons against infectious disease. Effective cures for terrible afflictions like pneumonia, syphilis and tuberculosis were suddenly at hand. Moreover, many of the drugs that made them possible were versatile enough to knock out a wide range of deadly bacterial threats. Unfortunately, antibiotics have a fundamental limitation: They're useless against viruses, which cause most infectious diseases. Antiviral drugs have proven far more difficult to create, and almost all are specifically directed at a few particular pathogens - namely HIV, herpes viruses and influenza viruses. The two "broad-spectrum" antivirals in use, ribavirin and interferon-alpha, both cause debilitating side effects.

U.N. Secretary-General Focuses On MDGs During African Union Summit

Addressing the 14th African Union (AU) Summit on Sunday, U.N. Secretary-General Ban Ki-moon called for African countries to maintain their commitment to the Millennium Development Goals (MDGs), "which include reducing poverty, disease and child mortality, ahead of their target date of 2015, " BBC reports (1/31). "The global recession, energy crisis, food insecurity and climate change have all made development more difficult and more urgent, [Ban] told more than 50 heads of state and government attending the three-day AU meeting" in Addis Ababa, Ethiopia, the U.N. News Centre writes. Ban noted that the MDG summit, planned for September, "will focus on harnessing support for the success of the MDGs, identifying gaps that need urgent attention, emphasizing priority areas for action and building a coalition capable of taking action, " according to the U.

Virulent Bacteria Offer Insight Into Host-Pathogen Interactions

Researchers at National Jewish Health have discovered how the virulent food-borne bacteria Listeria monocytogenes induces infected immune cells to sabotage their own defensive response. The studies offer insight into host-pathogen interactions and suggest potential therapeutic targets for food poisoning, tuberculosis and autoimmune diseases. In the Feb. 15 issue of the Journal of Experimental Medicine, Laurel Lenz, PhD, and his colleagues report that macrophages infected by the bacteria Listeria release interferon- (IFN- ), which makes them and nearby immune cells unresponsive to activation signals. This reduces immune resistance to the bacteria, which causes thousands of cases of food poisoning -- and more than 500 deaths -- each year in the United States.

Antibodies Attack Immune Proteins

Two studies published online on February 1 in the Journal of Experimental Medicine reveal that patients with a rare autoimmune disease produce antibodies that attack microbe-fighting immune proteins called cytokines. These findings may help explain why these patients suffer recurrent yeast infections. Autoimmune polyendocrine syndrome, or APS-I, afflicts one in 100, 000 people and is characterized by disrupted thyroid and adrenal gland function and recurrent skin infections with one type of yeast. Normally, the immune system produces cytokines that help protect the body against airborne yeast and other environmental pathogens. Two teams of researchers - one led by Anthony Meager at the National Institute for Biological Standards and Control (UK), and the other led by Desa Lilic at Newcastle University (UK) and Jean-Laurent Casanova at Rockefeller University (New York) - found that patients with APS-I produce autoantibodies that bind to and disarm these yeast-fighting cytokines.

Wars Less Deadly, Most War-Related Deaths Result From Disease, Hunger, Report Says

"Wars are less deadly than they once were and national mortality rates have continued to decline even during conflicts due to smaller scale fighting and better healthcare, " according to a study released Wednesday by the Human Security Report Project, Reuters reports. "The report noted that most deaths in wars result from hunger and disease but said improved healthcare in peacetime had cut death tolls even during wartime, as had stepped up aid to people in war zones, " according to the news service. The report found that since 2000, 90 percent fewer people have died in the average conflict annually compared with the 1950s. "In 2007, the average conflict killed fewer than 1, 000 people as a direct result of violence, and there had been a 70 percent decline in the number of high-intensity conflicts since the end of the Cold War 20 years ago, it said, " Reuters writes.

Government Of Canada Announces Significant Contribution To WHO Global Pandemic Relief Efforts
