LSUHSC researcher identifies new target to prevent fatal flu lung complication
Research led by Dr. Jay Kolls, Professor and Chairman of Genetics at LSU Health Sciences Center New Orleans, has identified a therapeutic target for acute lung injury resulting in acute respiratory distress syndrome, a highly fatal complication of influenza infection. view more (2009-09-30)
Chronic infection persists by targeting stromal cell network in lymphoid organs
One of the biggest challenges to treating infectious diseases and developing preventive vaccines is the ability of many chronic infections to suppress the immune T-cell response over time. view more (2007-09-19)
Researchers seek to solve mystery of natural HIV control
An international, multi-institutional research consortium is seeking to discover how a few HIV-infected individuals are naturally able to suppress replication of the virus. view more (2006-08-17)
Researchers Examine Evolution of Genes that Trigger the Body's Immune Response to Viral Infection
Virginia Commonwealth University Institute of Molecular Medicine researchers have traced the evolutionary origin of two genes that serve as primary cellular sensors of infection with RNA viruses, such as influenza, poliovirus, West Nile virus, and HIV, which may ultimately provide researchers with insight into a possible new pathway for the... view more...

First evidence for DNA-based vaccination against chronic hepatitis C
The first-proof-of-concept for a DNA-based therapeutic vaccination against chronic hepatitis C was announced today at EASL 2009, the Annual Meeting of the European Association for the Study of the Liver in Copenhagen, Denmark. view more (2009-04-23)
New gene regulation mechanism discovered
Researchers at Cold Spring Harbor Laboratory have discovered a new kind of messenger RNA molecule that is converted from non-protein coding status to protein coding status in response to cellular stress such as viral infection. view more (2005-10-21)
Shorter colds, milder flu may follow from newly revealed immune mechanism
Enlisted to help fight viral infections, immune cells called macrophages consume virus-infected cells to stop the spread of the disease in the body. view more (2005-10-10)
Chronic Infection Now Clearly Tied to Immune-System Protein
The reason deadly infections like human immunodeficiency virus (HIV) and hepatitis C never go away is because these viruses disarm the body's defense system. view more (2009-05-15)
Combination vaccine protects monkeys from ebola and Marburg viruses
An experimental, combination vaccine against Ebola and Marburg viruses using virus-like particles (VLPs) provides complete protection against infection in monkeys. view more (2008-02-27)
Risk of HIV transmission highest early in infection
New evidence suggests that the risk of HIV transmission may be highest in the early stages of infection. According to a study published in the April 1 issue of The Journal of Infectious Diseases, now available online, early infection accounted for nearly half of all transmission occurrences in an HIV-infected population in the province of Quebec,... view more...

AFRICAN HIV-1 EPIDEMIC NOT CAUSED BY MORE INFECTIOUS VIRAL SUBTYPE (p 1149)
The explosive HIV-1 epidemic in sub-Saharan Africa is unlikely to be the result of a viral subtype with increased infectivity, according to the results of a study published in this week’s issue of THE LANCET. The HIV-1 epidemic in eastern and southern sub-Saharan Africa is mainly caused by HIV-1 subtypes A, C, and D, whereas those in the USA... view more... (2001-04-11)
Technology identified could reduce the spread of rice virus
Building on plant virus research started more than 20 years ago, a biologist at Washington University in St. Louis and his colleague at the Donald Danforth Plant Science Center in St. Louis have discovered a technology that reduces infection by the virus that causes Rice Tungro Disease, a serious limiting factor for rice production in Asia. view more (2009-02-11)
Nature Medicine study shows Peregrine's bavituximab can cure lethal virus infections
Peregrine Pharmaceuticals, Inc. (NASDAQ: PPHM) today reported publication of data in Nature Medicine that supports the broad anti-viral potential of the company's novel anti-phosphatidylserine (anti-PS) antibody platform, showing that its PS-targeting drug bavituximab can cure lethal virus infections in animal disease models. view more (2008-11-24)
Genome circularization and RNA virus replication
As featured on the cover of the August 15th issue of G&D, an Argentinian research team, led by Dr. Andrea Gamarnik, report on their recent discovery of a novel mechanism of dengue virus replication. view more (2006-08-01)
HPV vaccine does not appear to be effective for treating pre-existing HPV infection
For women with human papillomavirus (HPV) infection, use of the HPV-16/18 vaccine will not accelerate reduction of the virus and should not be used to treat the infection, according to a study in the August 15 issue of JAMA. view more (2007-08-15)
Blood test could avoid inappropriate use of antibiotics for respiratory infections (pp 600)
A rapid blood test to help distinguish between bacterial and other (predominantly viral) infections could substantially reduce the inappropriate use of antibiotics for common infections, conclude authors of a study in this week's issue of THE LANCET. Lower respiratory tract infections are often treated with antibiotics-even though there is often... view more... (2004-02-18)
LIAI scientists make major advance in the fight against chronic virus infections
A major finding that could lead to a new approach for treating hepatitis C and other chronic virus infections was announced today by researchers at the La Jolla Institute for Allergy & Immunology (LIAI). view more (2006-10-10)
Modified crops reveal hidden cost of resistance
Genetically modified squash plants that are resistant to a debilitating viral disease become more vulnerable to a fatal bacterial infection, according to biologists. view more (2009-10-27)
New insights into how brain responds to viral infection
Scientists at Columbia University Mailman School of Public Health have discovered that astrocytes, supportive cells in the brain that are not derived from an immune cell lineage, respond to a molecule that mimics a viral infection using cellular machinery similar to that used by classical immune cells in the blood. view more (2009-04-01)
Study Highlights Need For Hepatitis C Vaccine (pp 1452, 1478)
A US study in this week's issue of THE LANCET highlights a high rate of hepatitis C virus (HCV) infection among injection-drug users, and that immunity against persistent HCV infection can be acquired. The authors suggest that vaccines should be tested to reduce the burden of liver disease associated with HCV infection. Around 4 million people in... view more... (2002-04-24)
