Cell division find prompts overhaul of immune response modelling
Research at the Walter and Eliza Hall Institute into the mechanics of how two types of white blood cells grow and die is fundamentally changing the development of computer models that are used to predict how immune system cells respond to a pathogenic threat. view more (2009-07-21)
How do we see bacteria
Understanding how the body's immune system recognises and responds to microorganisms can be a major step in the development of new therapies against infectious diseases. Towards this aim, a paper just released in the October issue of Embo reports1 discusses the process used by mammals to respond to bacteria such as Helicobacter pylori, Listeria... view more...

Mutation protects from HIV - and increases risk of hepatitis C
More than 40 million people worldwide are infected with the human immunodeficiency virus HIV. In Africa alone this incurable immune deficiency caused more than two million deaths last year. Yet some people are resistant to infection: the reason for this is a mutation in their DNA which prevents the HIV virus from invading certain immune cells and... view more... (2002-07-17)
Researcher tricks immune system in diabetic mice
The body's immune system hates strangers. When its security patrol spots a foreign cell, it annihilates it. view more (2008-11-21)
Therapeutic vaccine for ovarian cancer in clinical trials
Prima BioMed (ASX: PRR) announced today at the "Thank You" Day celebration at Sydney Children's Hospital that it has completed initial recruitment of its Phase IIa clinical trial in ovarian cancer at the Austin Hospital. view more (2005-10-12)
Parasite lipids against asthma or diabetes
Dutch research has demonstrated that lipids from the parasite schistosoma can inhibit human immune responses. This property makes the lipids interesting for a possible new treatment of diseases such as asthma and diabetes where the immune system responds inappropriately. During her doctoral research, Desiree van der Kleij discovered that lipids... view more... (2003-11-11)
White blood cells are picky about sugar
Biology textbooks are blunt-neutrophils are mindless killers. These white blood cells patrol the body and guard against infection by bacteria and fungi, identifying and destroying any invaders that cross their path. view more (2007-07-12)
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)
Scientists unmask key HIV protein, open door for more powerful AIDS drugs
University of Michigan scientists have provided the most detailed picture yet of a key HIV accessory protein that foils the body's normal immune response. view more (2008-09-29)
Pitt researchers find promising candidate protein for cancer prevention vaccines
Researchers at the University of Pittsburgh School of Medicine have learned that some healthy people naturally developed an immune response against a protein that is made in excess levels in many cancers, including breast, lung, and head and neck cancers. view more (2009-08-05)
Cancer immunoresistance linked to loss of tumor suppressor gene
Cancer immunoresistance may be partially due to loss of a well-known tumor suppressor gene, according to new research led by Andrew T. Parsa, MD, PhD, assistant professor of neurological surgery at the University of California, San Francisco. view more (2006-12-11)
Cancer vaccine one step closer
Andreea Ioan-Facsinay from Leiden University Medical Center has attached proteins from tumour cells to antibodies. With these she treated immune cells from a mouse. These treated cells were used to make a vaccine, which was shown to be effective in animal experiments. If the follow-up research is successful, vaccines against cancer will become... view more...

T cell immunity enhanced by timing of interleukin-7 therapy
That the cell nurturing growth factor interleukin-7 can help ramp up the ability of the immune system to remember the pathogenic villains it encounters is well known. view more (2008-02-04)
Three-in-one virus killer prevents common, often fatal infections
A novel combination therapy drastically reduces the infection rate of three viruses - and risk of death - in transplant patients with compromised immune systems. view more (2006-10-27)
Weight loss after gastric bypass surgery may protect against infection and cancer
Another health benefit of bariatric weight-loss surgery may be a heightened immune defense against cancer and infections, a new study suggests. The results will be presented at The Endocrine Society's 90th Annual Meeting in San Francisco. view more (2008-06-18)
How Toxoplasma gondii gets noticed
Researchers provide insight into how Toxoplasma gondii, a common parasite of people and other animals, triggers an immune response in its host. view more (2009-01-20)
New study finds how cells with damaged DNA alert the immune system
Research led by biologists at the University of California, Berkeley, has found that damage to a cell's DNA sets off a chain reaction that leads to the increased expression of a marker recognized by the body's immune system. view more (2005-07-05)
NIAID describes challenges, prospects for an HIV vaccine
Events of the past year in HIV vaccine research have led some to question whether an effective HIV vaccine will ever be developed. In the August 28 edition of the New England Journal of Medicine, officials from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, examine the extraordinarily... view more...

Herpes: Scientists find cellular process that fights virus
Scientists have discovered a new way for our immune system to combat the elusive virus responsible for cold sores: Type 1 herpes simplex (HSV-1). As reported in the advance online edition of Nature Immunology, a group of virus hunters from the Université de Montréal, in collaboration with American colleagues, have identified a... view more...

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)
