Aging immune cells increase risk for macular degeneration

As people age, their immune systems age, too. And new research at Washington University School of Medicine in St. Louis suggests that aging immune cells increase the risk for age-related macular degeneration, a major cause of blindness in the United States.

			High-fat, high-cholesterol diet depletes ranks of artery-protecting immune cells New research from scientists at the La Jolla Institute for Allergy and Immunology shows how a diet high in fat and cholesterol depletes the ranks of artery-protecting immune cells, turning them into promoters of inflammation, which exacerbate atherosclerotic plaque buildup that occurs in cardiovascular disease.

			New award will help research into immune system differences that trigger food allergies Adora A. Lin, M.D., Ph.D., an attending physician in Children's department of Allergy and Immunology, was awarded $240,000 to improve understanding of how children's immune systems tolerate or react to certain food allergens--sometimes triggering a cascade of side effects that can be fatal.

	Specific immune cells may help slow progression of ALS, research shows New research into Amyotrophic Lateral Sclerosis (ALS) - also known as motor neuron disease - shows that specific immune cells may help slow progression of the disease, an important step towards developing new therapies to treat patients.

	Roles of Selectins in the Immune System Selectins are a family of carbohydrate-binding transmembrane molecules found on the surface of endothelial cells, leukocytes and platelets.

	Functions of MHC in the Immune System The major histocompatibility complex (MHC) is a group of genes that encode proteins on the cell surface that have an important role in immune response.

	Researchers discover key link between fat, immune cells and heat regulation Scientists have just made a surprising discovery involving fat and special immune cells that live within it -- it turns out that 'gd T cells' are the key cogs in the biological wheel that regulates our body heat and protects us against cold shock.

	Monash scientists discover how gonorrhea-causing superbug evades the immune system Every year, more than 100 million people worldwide develop the sexually transmitted disease gonorrhea, with health consequences such as infertility, transmission of the disease to newborn babies, and increased risk of HIV infections. There has been a 63 percent rise in gonorrhea in Australia over the past five years.

	Research reveals immune suppressive role of soluble antibodies in tumor progression Wistar researchers have found that soluble antibodies promote tumor progression by inducing accumulation of myeloid-derived suppressor cells (MDSCs) in pre-clinical cancer models. Results were published online in Cancer Immunology Research.
