Treating autoimmune disease without harming normal immunity
With potentially major implications for the future treatment of autoimmunity and related conditions, scientists have found a way to remove the subset of antibody-making cells that cause an autoimmune disease, without harming the rest of the immune system. They studied an autoimmune disease called pemphigus vulgaris, a condition in which a patient's own immune cells attack a protein called desmoglein-3 that normally adheres skin cells.

Harnessing an innate repair mechanism enhances success of retinal transplantation
Cell replacement therapies hold promise for many age-related diseases, but efforts to bring treatments to patients have not been very successful -- in large part because the newly derived cells can't integrate efficiently into tissues affected by the ravages of aging. This is poised to change. Researchers have harnessed a naturally occurring anti-inflammatory mechanism that repaired the eye and significantly enhanced the success of retinal regenerative therapies in mice. The results could be particularly significant for macular degeneration.

New experimental system sheds light on how memory loss may occur
Spatial memory decays when the entorhinal cortex is not functioning properly, a new mouse model shows. The study, say the authors, provides new information about how dysfunction of this circuit may contribute to memory loss in Alzheimer's disease.

New insight into the most common genetic cause of ALS, FTD
Scientists have discovered a novel function of the C9orf72 protein which is linked to amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) -- giving a new insight into the most common genetic cause of the degenerative diseases.

Researchers identify calorie-burning pathway in fat cells
Investigators have identified a natural molecular pathway that enables cells to burn off calories as heat rather than store them as fat. This raises the possibility of a new approach to treating and preventing obesity, diabetes, and other obesity-linked metabolic disorders including cancer.

Study finds potential treatment for non-alcoholic fatty liver disease
Researchers report on a targeted molecular therapy that dramatically reduces the initial development of non-alcoholic fatty liver disease (NAFLD) in laboratory mouse models of the disease. The study found increased levels of an enzyme called cdk4 in patients with NAFLD and in mouse models. Using two drugs that inhibit cdk4 in mouse models reduced development of hepatic steatosis -- the first stage of the disease.

Likelihood of widespread Zika outbreak in United States low
High mosquito and human population densities, combined with mosquito breeding conditions, are the central cause for Zika virus.

Weight-loss technologies train the brain to resist temptation
Can a computer game train your brain to resist sweets? The game is designed to improve a person's "inhibitory control," the part of the brain that stops you from giving into unhealthy cravings -- even when the smell of French fries is practically begging you to step inside a fast food restaurant. Researchers are testing whether a new smartphone app and computer game can change behaviors.
