Breast Tumors in Mice Eradicated Using Cancer Vaccine
A team from the University of Pennsylvania School of Medicine has shown that by using a cancer vaccine based on the bacterium Listeria monocytogenes, they can cure mice with established breast tumors. view more (2005-09-15)
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)
Case Western Reserve University researchers find protein associated with brain cell death
Neuroscientists at the Case Western Reserve University School of Medicine have found evidence of which protein in the brain's immune cells triggers a cascade of reactions that produces unregulated free radical production that eventually leads to the neural cell death found in Alzheimer's disease. view more (2006-07-19)
Using insects to test for drug safety
Insects, such as some moths and fruit flies, react to microbial infection in the same way as mammals and so can be used to test the efficiency of new drugs, thereby reducing the need for animal testing. view more (2009-09-08)
Immunotherapy for Cancer: Inflammations Open up Access to Tumours
Although the immune system potentially recognizes tumour cells as foreign and destroys them, vaccination therapies have so far been disappointing. Malignant tumours seem to establish a special environment that blocks access for immune cells. However, an experimentally induced inflammation can overcome the tumour's intrinsic resistance for... view more... (2004-05-13)
New study shows antibody-interleukin complexes stimulate immune responses
The findings could also be significant for developing new ways to help patients with autoimmune diseases such as rheumatoid arthritis, multiple sclerosis, or juvenile diabetes. view more (2006-02-23)
Mother's immune system may block fetal treatments for blood diseases
Pediatric researchers have resolved an apparent contradiction in the field of prenatal cell transplantation- a medical approach that holds future promise in correcting sickle cell disease and other serious congenital blood disorders. view more (2009-08-17)
Yale scientists create artificial 'cells' that boost the immune response to cancer
Using artificial cell-like particles, Yale biomedical engineers have devised a rapid and efficient way to produce a 45-fold enhancement of T cell activation and expansion, an immune response important for a patient's ability to fight cancer and infectious diseases, according to an advance on line report in Molecular Therapy. view more (2008-02-27)
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)
Microbes start immune response by sneaking inside cells
Immune cells that are the body's front-line defense don't necessarily rest quietly until invading bacteria lock onto receptors on their outside skins and rouse them to action, as previously thought. In a new paper, University of Michigan scientists describe their findings that bacteria can barge inside these guard cells and independently initiate... view more... (2007-04-16)
Immune cells ameliorate hypertension-induced cardiac damage in mice
Researchers in Berlin, Germany have found that a specific type of immune cell, the regulatory T lymphocyte (Treg) plays an important role in hypertension-induced cardiac damage. view more (2009-06-10)
Rare disorder gives modelers first glimpse at immune system development
Children born without thymus glands have given Duke University Medical Center researchers a rare opportunity to watch as a new immune system develops its population of infection-fighting T-cells. view more (2009-06-17)
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)
MS patients have higher spinal fluid levels of suspicious immune molecule
A protein that helps keep immune cells quiet is more abundant in the spinal fluid of patients with multiple sclerosis (MS), further boosting suspicion that the protein, TREM-2, may be an important contributor to the disease. view more (2008-09-30)
Wistar scientists find key to keeping killer T cells in prime shape for fighting infection, cancer
Like tuning a violin to produce strong, elegant notes, researchers at The Wistar Institute have found multiple receptors on the outside of the body's killer immune system cells which they believe can be selectively targeted to keep the cells in superb infection- and disease-fighting condition. view more (2008-12-01)
Molecular 'signature' protects cells from viruses
Every cell constantly produces a whole arsenal of proteins. The instruction what is to be built comes from the cell nucleus: this is where the DNA is stored, the heredity molecule in which, so to speak, the construction blueprints for all cellular proteins are stored. view more (2006-10-13)
Identification of protein able to stimulate production of T-cells
A team of Canadian and Finnish scientists has identified a protein able to stimulate the production of T-cells, the white blood cells involved in the recognition and the elimination of infectious agents. view more (2008-07-23)
Monitoring the response to vaccination against melanoma
A new study published in PLoS Medicine this week describes a way to measure the immune response in people treated with an experimental vaccine to melanoma. view more (2005-09-20)
Study identifies molecule essential for proper localization of blood stem cells
Scientists at the Massachusetts General Hospital (MGH) Center for Regenerative Medicine and the Harvard Stem Cell Institute (HCSI) have defined a molecule that dictates how blood stem cells travel to the bone marrow and establish blood and immune cell production. view more (2006-01-16)
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)
