University of Pennsylvania Researchers Identify Gatekeeper Involved in Chronic Inflammatory Diseases
he road to many an inflammatory disease is guarded by a cytokine messenger protein called interleukin-27, according to researchers from the University of Pennsylvania School of Veterinary Medicine. Chronic inflammation results when the immune system becomes over stimulated and begins attacking healthy tissue in excess. view more (2006-08-22)
Ume'å scientist presents discoveries about natural immunity in Science
A team including scientists at UCMP (Ume'å Center for Molecular Pathogenesis), a research unit at Ume'å University, shows in last week's issue of the journal Science that the protein PGRP-LC plays a crucial role in so-called innate immunity. Professor Dan Hultmark, post-doctoral fellow Svenja Stöven, and doctoral candidate Thomas... view more... (2002-03-04)
Cancer-Causing Protein Can Also Help Fight the Tumors It Causes
Oncogenes are genes that when mutated or expressed in high concentrations can cause normal cells to become cancerous. view more (2009-06-19)
New discovery paves the way for new diagnosis of serious lung disease
The discovery by Uppsala University researchers of a previously unknown protein in the cells of the lower air ways brings new potential for early diagnosis of a serious lung disease. view more (2009-03-02)
The molecular mechanism of a diabetes vaccine revealed
A team of researchers led by Prof. Irun Cohen of the Weizmann Institute of Science Immunology Department has revealed the molecular mechanism of a vaccine for Type 1 diabetes. view more (2006-06-20)
Immune cells predict outcome of West Nile virus infection
Infection with West Nile virus (WNV) causes no symptoms in most people. However, it can cause fever, meningitis, and/or encephalitis. What determines the outcome of infection with WNV in different people has not been determined. view more (2009-10-13)
Rac 1 and 2, two proteins essential to triggering of the immune response
The dendritic cells act as the body's sentries, standing guard around the clock. As soon as they detect a potential enemy, they alert the T cells, whose role is to defend the body. At the Institut Curie, CNRS researchers in an Inserm laboratory have filmed the encounter of dendritic cells and T cells. They have shown that this "rendez-vous",... view more... (2004-08-23)
How Montezuma gets his revenge
Every year, about 500 million people worldwide are infected with the parasite that causes dysentery, a global medical burden that among infectious diseases is second only to malaria. view more (2008-06-16)
Limiting damage after heart transplantation
Scientists from Imperial College School of Medicine at Harefield Hospital may have found a way of dampening down damaging immune responses following heart transplants. Professor Rose will describe her work at the British Society for Immunology’s Congress 2000 in Harrogate today (Thursday 7 December 2000). World-wide, 5,000 heart transplants... view more...

UGA researchers one step closer to cancer vaccine
When cells become cancerous, the sugars on their surfaces undergo distinct changes that set them apart from healthy cells. For decades, scientists have tried to exploit these differences by training the immune system to attack cancerous cells before they can spread and ravage the body. view more (2007-10-30)
Gene against bacterial attack unravelled
Dutch researcher Joost Wiersinga from AMC Medical Centre in Amsterdam has unravelled a genetic defence mechanism against the lethal bacteria Burkholderia pseudomallei. The research is the next step towards a vaccine against this bacterium suitable for bioweapons. view more (2008-10-29)
HIV isolate from Kenya provides clues for vaccine design
Two simple changes in its outer envelope protein could render the AIDS virus vulnerable to attack by the immune system, according to research from Kenya and the Fred Hutchinson Cancer Research Center published in PLoS Medicine. view more (2008-01-03)
Scientists identify new role for lung epithelial cells in sensing allergens in the air
Researchers at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, and at Ghent University in Ghent, Belgium, have identified a new role for certain lung cells in the immune response to airborne allergens. view more (2009-03-31)
UBC researchers identify key behavior of immune response to Listeria
A team of University of British Columbia microbiologists has identified a key defence mechanism used by the immune system against Listeria with strong implications for the future development of vaccines. view more (2009-10-06)
Study reveals how a common virus eludes the immune system
Viruses have numerous tricks for dodging the immune system. In the September 7, 2009 issue of the Journal of Cell Biology, Stagg et al. reveal a key detail in one of these stratagems, identifying a protein that enables cyto¬megalovirus to shut down an antiviral defense (online August 31). view more (2009-08-31)
DNA of good bacteria drives intestinal response to infection
A new study shows that the DNA of so-called "good bacteria" that normally live in the intestines may help defend the body against infection. view more (2008-10-03)
UCLA scientists identify how key protein keeps chronic infection in check
Why is the immune system able to fight off some viruses but not others, leading to chronic, life-threatening infections like HIV and hepatitis C? view more (2009-05-08)
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)
Vitamin D deficiency in infants and nursing mothers carries long-term disease risks
Once believed to be important only for bone health, vitamin D is now seen as having a critical function in maintaining the immune system throughout life. view more (2008-12-17)
USC researchers discover novel way to develop tumor vaccines
Researchers at the University of Southern California (USC) have uncovered a new way to develop more effective tumor vaccines by turning off the suppression function of regulatory T cells. view more (2008-03-03)
