New insight in the fight against the Leishmania parasite
Professor Albert Descoteaux's team at Centre INRS - Institut Armand-Frappier has gained a better understanding of how the Leishmania donovani parasite manages to outsmart the human immune system and proliferate with impunity, causing visceral leishmaniasis, a chronic infection that is potentially fatal if left untreated. view more (2009-10-26)
Sperm may play leading role in spreading HIV
Sperm, and not just the fluid it bathes in, can transmit HIV to macrophages, T cells, and dendritic cells (DCs), report a team led by Ana Ceballos at the University of Buenos Aires in Argentina. view more (2009-10-26)
Stanford study identifies cellular mechanism that causes lupuslike symptoms in mice
Macrophages, the scavenger cells of the body's immune system, are responsible for disposing of dying cells. Stanford University School of Medicine researchers have identified one pathway in this important process in mice that, if disrupted, causes a lupuslike autoimmune disease. view more (2009-10-19)
Major discovery opens door to leishmania treatment
Leishmania is a deadly parasitic disease that affects over 12 million people worldwide, with more than 2 million new cases reported every year. view more (2009-10-07)
Reactive oxygen in fruit flies acts as a cell signalling mechanism for immune response
For years, health conscious people have been taking antioxidants to reduce the levels of reactive oxygen in their blood and prevent the DNA damage done by free radicals, which are the result of oxidative stress. But could excessive use of antioxidants deplete our immune systems? view more (2009-09-24)
To regenerate muscle, cellular garbage men must become builders
For scientists at the European Molecular Biology Laboratory (EMBL) in Monterotondo, Italy, what seemed like a disappointing result turned out to be an important discovery. view more (2009-09-23)
Pitt study finds molecular link between insulin resistance and inflammation
An exploration of the molecular links between insulin resistance and inflammation may have revealed a novel target for diabetes treatment, say scientists at the John G. Rangos Sr. Research Center, Children's Hospital of Pittsburgh of UPMC. view more (2009-08-27)
Einstein researchers identify potential target for metastatic cancer
The deadliest part of the cancer process, metastasis, appears to rely on help from macrophages, potent immune system cells that usually defend vigorously against disease, researchers at Albert Einstein College of Medicine of Yeshiva University report. view more (2009-08-11)
Scientists open doors to diagnosis of emphysema
Chronic inflammatory lung diseases like chronic bronchitis and emphysema are a major global health problem, and the fourth leading cause of death and disability in developed countries, with smoking accounting for 90% of the risk for developing them. view more (2009-08-03)
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)
Common allergy drug reduces obesity and diabetes in mice
Crack open the latest medical textbook to the chapter on type 2, or adult-onset, diabetes, and you'll be hard pressed to find the term "immunology" anywhere. view more (2009-07-27)
Stripping leukemia-initiating cells of their 'invisibility cloak'
Two new studies reveal a way to increase the body's appetite for gobbling up the cancer stem cells responsible for acute myeloid leukemia (AML), a form of cancer with a particularly poor survival rate. view more (2009-07-24)
Vitamin D, curcumin may help clear amyloid plaques found in Alzheimer's disease
UCLA scientists and colleagues from UC Riverside and the Human BioMolecular Research Institute have found that a form of vitamin D, together with a chemical found in turmeric spice called curcumin, may help stimulate the immune system to clear the brain of amyloid beta, which forms the plaques considered the hallmark of Alzheimer's disease. view more (2009-07-16)
Harvard scientists solve mystery about why HIV patients are more susceptible to TB infection
A team of Harvard scientists has taken an important first step toward the development of new treatments to help people with HIV battle Mycobacterium tuberculosis (TB) infection. view more (2009-07-01)
Research suggests new cellular targets for HIV drug development
Focusing HIV drug development on immune cells called macrophages instead of traditionally targeted T cells could bring us closer to eradicating the disease, according to new research from University of Florida and five other institutions. view more (2009-05-28)
What separates dangerous blood vessel plaques from benign ones
Researchers say they have evidence to explain what separates your average blood vessel plaque from those that are at high risk for triggering the development of dangerous-even fatal-blood clots. view more (2009-05-06)
New light shed on the enigma of salt intake and hypertension
A high salt intake has been implicated in cardiovascular disease risk for 5000 years. But salt-sensitive hypertension still remains an enigma. view more (2009-05-04)
New study overturns orthodoxy on how macrophages kill bacteria
For decades, microbiologists assumed that macrophages, immune cells that can engulf and poison bacteria and other pathogens, killed microbes by damaging their DNA. A new study from the University of Illinois disproves that. view more (2009-04-28)
A novel method of isolating high quality RNA from Kupffer cells
Kupffer cells, resident tissue macrophages that line the liver sinusoids, play a key role in modulating inflammation in a number of experimental models of liver injury. view more (2009-04-17)
Immune reaction to metal debris leads to early failure of joint implants
Researchers at Rush University Medical Center have identified a key immunological defense reaction to the metals in joint replacement devices, leading to loosening of the components and early failure. view more (2009-03-05)
