Hodgkin lymphoma -- new characteristics discovered
Researchers are still discovering new characteristics of Hodgkin lymphoma, a common form of cancer of the lymphatic system. The malignant cells are derived from white blood cells (B cells), but have lost a considerable part of the B cell-specific gene expression pattern. view more (2008-10-09)
'Erectile dysfunction' drugs heighten natural anti-cancer activity
Sildenafil and other "impotence drugs" that boost the production of a gassy chemical messenger to dilate blood vessels and produce an erection now also show promise in unmasking cancer cells so that the immune system can recognize and attack them, say scientists at the Johns Hopkins Kimmel Cancer Center. view more (2006-12-08)
Regulatory B cells exist -- and pack a punch
Researchers at Duke University Medical Center have uncovered definitive evidence that a small but potent subset of immune system B cells is able to regulate inflammation. view more (2008-05-28)
Blood-vessel blocker aids cancer-killing virus
Cancer-killing viruses are a promising therapy for incurable brain tumors, but their effectiveness has been limited in part because immune cells rapidly move in and eliminate them. view more (2007-11-28)
Painkillers may threaten power of vaccines
With flu-shot season in full swing and widespread anticipation of the HPV vaccine to prevent cervical cancer, a new University of Rochester study suggests that using common painkillers around the time of vaccination might not be a good idea. view more (2006-11-29)
Penn researchers provide insights into how the immune system avoids attacking itself
A finding by University of Pennsylvania School of Medicine researchers about how immune cells "decide" to become active or inactive may have applications in fighting cancerous tumors, autoimmune diseases, and organ transplant rejection. view more (2006-10-13)
Examining TLR4 influences of B cell response
Chronic inflammation, which is at the root of multiple diseases, links periodontal disease to increased incidence of cardiovascular disease. view more (2009-05-06)
OHSU Cancer Institute finds that drug stimulated immune system in prostate cancer
In a multi-site study, Oregon Health & Science University Cancer Institute researchers have found that a drug called Ipilimumab, also known as MDX-010, works to stimulate the body's own immune system to fight prostate cancer. The drug was found to be effective in study participants with a serious type of prostate cancer - one where the tumor... view more... (2008-06-03)
Seaweed and fireflies brew may guide stem cell treatment for peripheral artery disease
An unlikely brew of seaweed and glow-in-the-dark biochemical agents may hold the key to the safe use of transplanted stem cells to treat patients with severe peripheral arterial disease (PAD), according to a team of veterinarians, basic scientists and interventional radiologists at Johns Hopkins. view more (2009-03-10)
Study identifies biomarker that safely monitors tumor response to new brain cancer treatment
A specific biomarker, a protein released by dying tumor cells, has been identified as an effective tool in an animal model to gauge the response to a novel gene therapy treatment for glioblastoma mulitforme. view more (2009-07-01)
Biodegradable microspheres deliver time release vaccines, stimulate different immune response
A new vaccine delivery system using microspheres of a biodegradable polymer may not only reduce the need for booster shots in some cases, but also appears to stimulate an immune response that traditional vaccines do not. view more (2007-03-01)
Team develops DNA compounds that could help treat lupus
A research team led by a University of Iowa investigator has generated DNA-like compounds that effectively inhibit the cells responsible for systemic lupus erythematosus -- the most common and serious form of lupus. view more (2009-05-28)
Protein's New Role Discovered in Autoimmune Disease
Investigators at the University of Alabama at Birmingham (UAB) have identified the previously unknown role of a chemical 'messenger' leading to autoimmune disorders like rheumatoid arthritis and lupus. view more (2008-01-03)
Transplant drug stimulates immune memory
Rapamycin, a drug given to transplant recipients to suppress their immune systems, has a paradoxical effect on cells responsible for immune memory, scientists at the Emory Vaccine Center have discovered. view more (2009-06-22)
Immune Cell Communication, Cooperation Keys to Hunting Viruses, Jefferson Immunologists Show
Immunologists at the Kimmel Cancer Center at Thomas Jefferson University in Philadelphia have used nanotechnology to create a novel 'biosensor' to solve in part a perplexing problem in immunology: how immune system cells called killer T-cells hunt down invading viruses. view more (2006-10-27)
Molecular switch the key to disease breakthroughs on many fronts
A single molecular switch may be the key to fighting disease on several fronts. Research published in SCIENCE this week, suggests that the blocking of one signalling pathway may be crucial in tackling auto-immune disease, transplant rejection and leukaemia. Having identified a small family of signalling molecules that play an important role in... view more... (2002-07-16)
Ozone shuts down early immune response in lungs and body
As policy makers debate what levels of ozone in the air are safe for humans to breathe, studies in mice are revealing that the inhaled pollutant impairs the body's first line of defense, making it more susceptible to subsequent foreign invaders, such as bacteria. view more (2007-10-01)
Immunity in social amoeba suggests ancient beginnings
Finding an immune system in the social amoeba (Dictyostelium discoideum) is not only surprising but it also may prove a clue as to what is necessary for an organism to become multicellular, said the Baylor College of Medicine researcher who led the research that appears today in the journal Science. view more (2007-08-03)
Blood pressure enzyme can have tumor-sensing role
By increasing production of a blood pressure-regulating enzyme in mice, researchers have found they can enhance the mouse immune system's ability to sense tumor growth. view more (2008-04-08)
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)
