Macrophage News and Research

RSS

A macrophage is a type of white blood cell that surrounds and kills microorganisms, removes dead cells, and stimulates the action of other immune system cells.

Potential new targeted treatments for Lupus

New research provides clues about the causes of lupus symptoms and suggests specific new targeted treatment strategies, according to Nilamadham Mishra, M.D., from Wake Forest University Baptist Medical Center, in presentations this week at the American College of Rheumatology in Boston.

Inflammation causes insulin resistance not obesity

Researchers at the University of California, San Diego (UCSD) School of Medicine have discovered that inflammation provoked by immune cells called macrophages leads to insulin resistance and Type 2 diabetes.

Antibody might help starve cancerous tumors

An antibody might offer a safe and effective complement to anti-cancer therapies designed to starve malignant tumors by pruning the blood vessels that feed them, researchers report in the November 2 issue of the journal Cell, a publication of Cell Press.

Immune cell age plays role in retinal damage in age-related macular degeneration

Studying a mouse model of age-related macular degeneration, the leading cause of blindness in older Americans, scientists at Washington University School of Medicine in St. Louis have found age is key in determining whether damaging blood vessels will form beneath the retina and contribute to vision loss.

Low-density lipoprotein may contribute to vascular diseases

Low-density lipoprotein (LDL), a transporter of cholesterol, may also contribute to vascular diseases by a previously unidentified mechanism, according to a report published online this week in EMBO reports.

Role of cholesteryl ester hydrolase in reducing heart disease identified

Virginia Commonwealth University researchers have identified the role of a key enzyme called CEH in reducing heart disease, paving the way for new target therapies to reduce plaques in the arteries and perhaps in the future, help predict a patient's susceptibility to heart disease.

Legionnaire's bacterial proteins work together to survive

Proteins within the bacteria that cause Legionnaire's disease can kidnap their own molecular "coffin" and carry it to a safe place within the cell, ensuring their survival, Yale School of Medicine researchers report in Nature Wednesday.

New links in the cystic fibrosis chain uncover potential therapeutics

Cystic fibrosis (CF) is an inherited disease caused by mutations in the CFTR gene.

Chemists turn carbon monoxide into potential cardiovascular therapy

During Carbon Monoxide Awareness week, EPSRC highlights how researchers are harnessing the gas for beneficial use.Despite its deadly reputation, the gas carbon monoxide (CO) could actually save lives and boost health in future as a result of leading-edge UK research.

Discovery of protein that plays a key role in the recycling of iron from blood

Scientists working in the only lab at MIT doing hematology research have uncovered a protein that plays a key role in the recycling of iron from blood. Their work, described in the October 11 Journal of Clinical Investigation, could lead to new therapies for certain inherited blood disorders such as beta-thalassemia, a condition that causes chronic anemia.

Gene SIRT1 could lead to new cholesterol strategies

MIT researchers have discovered a link between a gene believed to promote long lifespan and a pathway that flushes cholesterol from the body. The finding could help researchers create drugs that lower the risk of diseases associated with high cholesterol, including atherosclerosis (clogged arteries) and Alzheimer's disease.

Human and avian influenza viruses target different cells in the lower respiratory tract of humans and other mammals

Researchers have identified which sites and cell types within the respiratory tract are targeted by human versus avian influenza viruses, providing valuable insights into the pathogenesis of these divergent diseases.

Re-educating immune system cells slows tumour growth

Immune system cells recruited by cancers to help them grow and spread could be 're-educated' to attack the tumours instead of aiding them, Cancer Research UK scientists announced at the National Cancer Research Institute (NCRI) Conference in Birmingham today (Wednesday).

4 Oct 2007

Depression, aging, and proteins made by a virus may all play role in heart disease

Researchers here have linked an increase in two immune system proteins essential for inflammation to a latent viral infection and proposed a chain of events that might accelerate cardiovascular disease.

Inhaled ozone impairs the body's first line of defense

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.
