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)
Malaria parasite impairs key immune system cells
Plasmodium, the parasite responsible for malaria, impairs the ability of key cells of the immune system to trigger an efficient immune response. view more (2006-04-12)
New hope for HIV sufferers as immunosuppressant delays AIDS onset
A drug that suppresses the immune system delays the onset of AIDS in patients with HIV, according to a study published this week in BMC Medicine. Prednisolone, taken without any antiviral therapy, postponed the loss of T-cells that leads to AIDS in 50% of HIV sufferers by between 2 and 10 years. HIV leads to a complex disorder that combines an... view more... (2004-04-30)
University of Pennsylvania Researchers Discover "Killer" B Cells; New Link in the Evolution of Immunity
Researchers from the University of Pennsylvania School of Veterinary Medicine have discovered a unique evolutionary link between the immune systems of fish and mammals in the form of a primitive version of B cells, white blood cells of the immune system. view more (2006-09-21)
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)
Finding protection from tumor growth in unexpected places
Researchers have discovered that an enzyme commonly involved in regulating blood pressure also provides protection from tumor growth when strongly expressed in immune cells. view more (2007-06-06)
'Super' enzyme may lead way to better tumor vaccines
A "super" form of the enzyme Akt1 could provide the key to boosting the effect of tumor vaccines by extending the lives of dendritic cells, the immune-system master switches that promote the response of T-cells, which attack tumors, said researchers at Baylor College of Medicine in a report that appears in the "advance online... view more...

U of M study shows why treatment isn't effective for HIV
University of Minnesota researchers have answered a key question as to why antiretroviral therapy isn't effective in restoring immunity in HIV-infected patients. view more (2008-08-06)
Tumor wizardry wards off attacks from the immune system
Like the fictional wizard Harry Potter, some cancerous tumors seem capable of wrapping themselves in an invisibility cloak. Researchers at Washington University School of Medicine in St. Louis have found that pancreatic tumors hide from the body's immune surveillance by surrounding themselves with cells that make it hard for the immune system to... view more...

Stem cell transplant can grow new immune system in certain mice, Stanford researchers find
Researchers at the Stanford University School of Medicine have taken a small but significant step, in mouse studies, toward the goal of transplanting adult stem cells to create a new immune system for people with autoimmune or genetic blood diseases. view more (2007-11-26)
Dysentery uses 'sword and shield' to cause infection
Scientists have found that the bacterium that causes dysentery uses a 'sword and shield' approach to cause infection. view more (2005-02-23)
Not just a long distance relationship: immune cells in skin fight off infection better than the rest
Scientists at the University of Melbourne have discovered the local action of immune cells in the skin, which could improve treatment of viral skin infections. view more (2009-04-08)
Just in time for spring: Scientists find the cellular on and off switch for allergies and asthma
If you're one of the millions who dread the spring allergy season, things are looking up. view more (2009-04-30)
Modeling pathogen responses
The search for a vaccination against HIV has been in progress since 1984, with very little success. Traditional methods used for identifying potential cellular targets can be very costly and time-consuming. view more (2007-10-12)
Researchers identify a cell type that limits stroke damage
A research team including Serge Rivest of University Laval's Faculty of Medicine has demonstrated the existence of a type of cells that limits brain damage after a stroke. The study was recently published in the online version of Nature Medicine. view more (2009-01-28)
NIH scientists find a novel mechanism that controls the development of autoimmunity
Scientists at the National Institutes of Health (NIH) have found a mechanism in the immune systems of mice that can lead to the development of autoimmune disease when turned off. view more (2008-08-14)
Fight against hay fever and other allergies helped by new immune system discovery
A mechanism which can lead to hay fever and other allergic reactions, by preventing the immune system from regulating itself properly, has been discovered by scientists. view more (2007-12-27)
Cell study explains why younger people more at risk of vCJD
Specific cells within the immune system could help explain why younger people are more susceptible to variant CJD, scientists believe. view more (2009-10-14)
First human study confirms that immune cells can be a primary cause of bone loss in gum disease
Researchers at The Forsyth Institute have confirmed in human gingival tissue that immune cells play a destructive role in periodontal disease. view more (2006-08-28)
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)
