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)
Chronic fatigue syndrome linked to stomach virus
Chronic fatigue syndrome, also known as ME (myalgic encephalitis), is linked to a stomach virus, suggests research published ahead of print in Journal of Clinical Pathology. view more (2007-09-14)
Immunologists find better way to boost the immune system
Immunologists have discovered how to manipulate the immune system to increase its power and protect the body from successive viral infections. view more (2008-01-23)
How do the rules of immunity change during chronic infections?
After a viral infection, a small percentage of the T cells generated to kill virus-infected cells remain on guard to establish long-term immunity. view more (2007-04-10)
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)
Blocking effects of viral infections may prevent asthma in young children
Babies who get severe respiratory viral infections are much more likely to suffer from asthma as they get older. view more (2007-11-08)
New culprit for viral infections among elderly -- an overactive immune response
Researchers at Yale School of Medicine have found that exaggerated responses of the immune system explain why the elderly succumb to viral infections more readily than younger people. view more (2009-11-19)
A new step towards an AIDS vaccine
Progressive disease after HIV infection is inversely correlated with the presence of plasmacytoid dendritic cells (pDCs), a subset of the dendritic cell family and the major producers of type 1 interferon in the body. view more (2005-10-14)
Yale study shows why cigarette smoke makes flu, other viral infections worse
A new study by researchers at Yale School of Medicine could explain why the cold and flu virus symptoms that are often mild and transient in non-smokers can seriously sicken smokers. Published in the Journal of Clinical Investigation, the study also identified the mechanism by which viruses and cigarette smoke interact to increase lung... view more... (2008-07-25)
Immune exhaustion driven by antigen in chronic viral infection
A main reason why viruses such as HIV or hepatitis C persist despite a vigorous initial immune response is exhaustion. The T cells, or white blood cells, fighting a chronic infection eventually wear out. view more (2009-05-14)
Early exposure to common viral infection does not protect against allergy
Common viral infections in early childhood do not protect against allergy, concludes research in Thorax. If anything, the evidence points to an increased risk. view more (2002-04-25)
Immune cells fighting chronic infections become progressively 'exhausted,' ineffective
A new study of immune cells battling a chronic viral infection shows that the cells, called T cells, become exhausted by the fight in specific ways, undergoing profound changes that make them progressively less effective over time. view more (2007-10-19)
UCR-led study identifies crucial mechanism involved in immune response against viruses
A research team led by UC Riverside scientists has shown that the common fruit fly can serve as an excellent model for studying the immunity animals are born with for fighting viral infections. view more (2006-03-24)
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)
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)
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)
Genetic vaccine promising against chronic hepatitis C
A potential vaccine candidate against chronic hepatitis C (HCV) infections is presented in a thesis from Karolinska Institutet. The new genetic vaccine can activate immune responses that are needed to clear HCV, a disease that today is difficult to treat effectively. The hepatitis C virus (HCV) is a major cause of chronic liver disease worldwide.... view more... (2004-06-07)
May hepatic granulomas be part of the histological spectrum of chronic hepatitis C?
While older large series of patients with hepatic granulomas have found sarcoidosis and tuberculosis to be the most common causes of hepatic granulomas, recent works have noted some patients with chronic hepatic C and hepatic granulomas and no other obvious associations. view more (2008-12-29)
Parasitic worm infections increase susceptibility to AIDS viruses
Persons infected with schistosomes, and possibly other parasitic worm infections, may be more likely to become infected with HIV than persons without worm infections, according to a study published July 23rd in the open-access journal PLoS Neglected Tropical Diseases. view more (2008-07-23)
Researchers explore the emerging role of infection in Alzheimer's disease
A number of chronic diseases are in fact caused by one or more infectious agents. For example, stomach ulcers are caused by Helicobacter pylori, chronic lung disease in newborns and chronic asthma in adults are both caused by Mycoplasmas and Chlamydia pneumonia, while some other pathogens have been associated with atherosclerosis. view more (2008-05-23)
