Old mystery solved, revealing origin of regulatory T cells that 'police' and protect the body
More than 150 years after the discovery of Hassall's corpuscles in 1849, the function of these round blobs of cells in the human thymus gland has now been explained. The answer, in turn, ends an intense hunt for the origin of regulatory T cells that has been under way for years. view more (2005-10-13)
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)
Science researchers genetically transform immune cells into tumor fighters
A team of researchers has genetically engineered normal immune cells to become specialized tumor fighters, demonstrating for the first time that these engineered cells can persist in the body and shrink large tumors in humans. view more (2006-09-01)
Immune system pathway identified to fight allergens, asthma
For the first time, researchers from the University of Pittsburgh School of Medicine have identified genetic components of dendritic cells that are key to asthma and allergy-related immune response malfunction. view more (2008-05-08)
Combined effect of proteins saves lives in cases of pneumonia
An effective host defence to the most prevalent form of pneumonia is only obtained if two proteins combine their forces. Dutch researcher Anita Rijneveld made this discovery during her PhD research at the Academic Medical Centre, University of Amsterdam. Using mice infected with the bacterium Streptococcus pneumoniae (the bacterium which causes... view more... (2003-05-16)
Infant transplant patients resist infections that kill adult AIDS patients
Investigators have discovered that some type of protective system goes into action in some cases when a baby's immune system is deficient. view more (2006-01-31)
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)
Researchers capture bacterial infection on film
Whilst most studies of bacterial infection are done after the death of the infected organism, this system developed by scientists at the University of Bath and University of Exeter is the first to follow the progress of infection in real-time with living organisms. view more (2009-07-28)
Antibody therapy prevents type 1 diabetes in mice
University of Pittsburgh investigators have successfully prevented the onset of type 1 diabetes in mice prone to developing the disease using an antibody against a receptor on the surface of immune T-cells. According to the investigators. view more (2007-01-09)
Vitamin A signals offer clues to treating autoimmunity
Distributed around the body, dendritic cells act as the security alarms of the immune system. After sensing the presence of intruders, dendritic cells can transmit the alarm to white blood cells or tell them to relax, depending on the signals they send out. view more (2009-03-02)
Elderly immune system needs a boost
Elderly cancer patients need a combination of treatments tailor-made to their specific needs to successfully combat the disease. view more (2009-10-09)
Study shows cancer vaccines led to long-term survival for patients with metastatic melanoma
Hoag Memorial Hospital Presbyterian today announced promising data from a clinical study showing patient-specific cancer vaccines derived from patients' own cancer cells and immune cells were well tolerated and resulted in impressive long-term survival rates in patients with metastatic melanoma whose disease had been minimized by other therapies. view more (2009-07-29)
Scientists discover how to improve immune response to cancer at Princess Margaret Hospital
A team of scientists at The Campbell Family Institute for Breast Cancer Research (CFIBCR) at Princess Margaret Hospital and international collaborators have discovered how to trigger an improved immune response to cancer that could be included in new clinical trials that use a patient's own cells to destroy tumours. view more (2009-04-27)
Individuals vary their immune response according to age, sex and the costs
Is it always good to respond maximally when pathogens or disease strike, or should individuals vary their immune response to balance immediate and future costs? view more (2008-09-11)
Common diabetes drug may 'revolutionize' cancer therapies
Researchers at McGill University and the University of Pennsylvania have discovered that a widely used anti-diabetic drug can boost the immune system and increase the potency of vaccines and cancer treatments. view more (2009-06-04)
Communication within the immune system:Immune synapses cannot function without ZAP-70
A familial form of severe combined immune deficiency (SCID) is caused by anomalies of an enzyme called ZAP-70. If ZAP-70 is lacking or does not work, the T-cells, which play a key role in the mechanisms of immune defense, are no longer functional. Affected children therefore catch infections as soon as they are exposed to pathogenic... view more... (2002-10-24)
Discovering New Regulators Of The Immune System
London, U.K. and South San Francisco, CA, 15th September 2003. In an attempt to find new regulators of the immune system, a team of researchers at Rigel Pharmaceuticals, Inc. have created a successful method for discovering molecules that are involved in signalling pathways. As published this week in the Journal of Biology, the team conducted a... view more... (2003-09-12)
New vaccine stimulates colorectal cancer patient's immune systems to fight cancerous cells
British researchers have developed a vaccine that stimulates colorectal cancer patients' immune systems to fight cancerous cells. view more (2006-11-15)
Immune response to HIV in the brain
Using multi-disciplinary analysis that included cognitive, neurophysiologic, virologic, and molecular techniques, the team found both a low-level viral infection in the brain and immune cells that had infiltrated the brain in order to protect against the virus. view more (2006-04-28)
New target for HIV/AIDS drugs and vaccines discovered
Researchers from Rome, Italy, describe a finding in the August 2007 print issue of The FASEB Journal that could lead to new drugs to fight the HIV/AIDS virus, as well as new vaccines to prevent infection. view more (2007-07-27)
