NIH Scientists Discover Genetic Cause of Rare Vibration-Induced Hives

Scientists at the National Institutes of Health have identified a genetic mutation responsible for a rare form of inherited hives induced by vibration, also known as vibratory urticaria. Running, hand clapping, towel drying or even taking a bumpy bus ride can cause temporary skin rashes in people with this rare disorder. By studying affected families, researchers discovered how vibration promotes the release of inflammatory chemicals from the immune system’s mast cells, causing hives and other allergic symptoms.

Natural Protein Points to Effective Treatments for Inflammatory Diseases

Increasing the level of a naturally-produced protein, called tristetraprolin (TTP), significantly reduced or protected mice from inflammation, according to researchers at the National Institutes of Health. The results suggest that pharmaceutical compounds or other therapeutic methods that produce elevated levels of TTP in humans may offer an effective treatment for some inflammatory diseases, such as rheumatoid arthritis, psoriasis, and multiple sclerosis. The report appeared online Feb. 1 in the Proceedings of the National Academy of Sciences.

Surprising Brain Formation Pattern Shows Why Early Trauma May Cause Disease

Some of the earliest nerve cells to develop in the womb shape brain circuits that process sights and sounds, but then give way to mature networks that convert this sensory information into thoughts. This is the finding of a study led by researchers at NYU Langone Medical Center and published in the February 3 edition of Neuron.
