STING may take the bite out of autoimmune diseases like arthritis, Type 1 diabetes

Researchers discover STING's critical role in treating autoimmune diseases by evoking expression of enzyme IDO, which blocks immune attack on healthy body constituents. Mice with STING deficiency had no response to DNA nanoparticles, highlighting the protein's essential role in recognizing the molecule that senses DNA.

Effects of climate change on West Nile virus

A study projects how climate change affects West Nile virus-carrying mosquitoes across the southern US, with changes varying by region. Warmer temperatures and drier conditions may lead to longer mosquito seasons but smaller summer populations.

Cell transplants may be a novel treatment for schizophrenia

Researchers at the University of Texas Health Science Center at San Antonio suggest that cell transplants could be a promising treatment for schizophrenia. By transplanting interneurons into the brain, they were able to restore normal function in rats with impaired dopamine systems, which are involved in cognition, movement, and emotions.

Ants turn unwelcome lodgers into a useful standing army

Researchers found that permanent parasites that are normally a social burden protect their hosts against greater evils. The guest ants rise to defend their hosts against mobile raiders, greatly decreasing the probability of a raid. This co-evolutionary process maintains lesser evils when it helps prevent greater harm.

Insulin secretion disrupted by increased fatty acids

Researchers found that increased fatty acid levels suppress incretin-associated insulin release, highlighting the importance of β cell connectivity. Maintaining β cell connectivity may be a useful strategy for restoring glucose balance in type 2 diabetes.

Dingo wrongly blamed for extinctions

A University of Adelaide study finds that Aboriginal populations and climate change were more likely responsible for the extinction of Tasmanian tigers and devils on the mainland. The research used complex models to recreate the dynamic interaction between dingoes, climate, and human populations.

Researchers at Massachusetts General Hospital identify fibroblast growth factor 18 (FGF18) as a predictive marker for poor overall survival in ovarian cancer patients. Overexpression of the gene encoding FGF18 was associated with enhanced tumor blood vessel formation and expression of cancer-promoting cytokines.

New report finds no evidence that safety-net patients receive substandard primary care

A new study by George Washington University researchers finds no evidence that primary care physicians deliver less care to low-income and vulnerable patients. Despite critics' claims of substandard care, the study analyzed data from over 31,000 visits and found comparable care for all patients regardless of insurance status.

The new face of Medicaid: Incoming enrollees may be younger; more white men, smokers, drinkers

A new University of Michigan study reveals that incoming Medicaid enrollees may be younger, whiter, and healthier than current beneficiaries. These individuals are more likely to be smokers and heavy drinkers. Overall, the expansion could bring in a new, healthier group with different demographic characteristics.
