Possible Therapeutic Strategy for Inflammation-Mediated Diseases

New research shows that TH17 cells can convert from pro-inflammatory to anti-inflammatory, revealing a possible therapeutic strategy for inflammation-mediated diseases. A type of immune cell that promotes inflammation during the immune response, TH17, can convert into another type of cell that reduces inflammation, Yale researchers have found. The finding, published April 29 in Nature, points […]

Controlling the Thalamus with Dynamic Synapses

Neuroscientists from Brown University show how cells in the brain’s cortex can either stifle or enhance sensory information incoming from the thalamus, thereby allowing it to focus on just some of the many sensory inputs it might choose to consider. Providence, Rhode Island (Brown University) — We consider only some of the sights, sounds, and […]

Scientists Shed New Light on Sensory Neural Development

New research from Yale University sheds light on sensory neural development and possible new ways to identify mechanisms that can repair damage to the central nervous system. Smell is the only sensory system with a back up, which throughout most of adult life forms new sensory neurons that express specific odor receptors. Now Yale researchers […]

New Tool to Explore Mysteries of the Immune System

Researchers from Yale University are using CyTOF, which stands for cytometry by time-of-flight, to explore mysteries of the immune system. Why do some individuals infected with the West Nile virus develop life-threatening infections while others never know they had more than a mosquito bite? That medical mystery is just one of the questions that Ruth […]

Virus Safely Destroys Brain Tumors

New research from Yale University details how scientists used a novel chimeric virus (VSV-LASV-GPC) containing genes from both Lassa and VSV to target and completely destroyed brain cancer without adverse actions within or outside the brain. Brain tumors are notoriously difficult for most drugs to reach, but Yale researchers have found a promising but unlikely […]

Stimulating Major Branches of the Immune System Halts Tumor Growth More Effectively

By stimulating both major branches of the immune system, researchers from MIT were able to halt the growth of a very aggressive form of melanoma in mice. The human immune system is poised to spring into action at the first sign of a foreign invader, but it often fails to eliminate tumors that arise from […]

Possible Personalized Treatments for More Aggressive Forms of Brain Cancer

New research from Yale University reveals that it may be possible to develop personalized treatments for more aggressive forms of brain cancer. DNA mutations can cause cancer but in some cases, more mutations may mean a better prognosis for patients. A Yale-led comprehensive genomic analysis of more than 700 brain tumors has revealed one such […]
