Overeating caused by a hormone deficiency in brain?
Rutgers scientists have found that when hormone glucagon like peptide-1 was reduced in the central nervous system of laboratory mice, they overate and consumed more high fat food. Although this is not the only reason why people overeat, the study provides new evidence that targeting neurons in the mesolimbic dopamine system -- a reward circuit in the brain -- rather than targeting the whole body might be a better way to control overeating and obesity with fewer side effects.

Shh! Don't wake the sleeping virus!
Scientists at Bar-Ilan University report on a novel experimental model that, for the first time, successfully mimics the 'sleeping' and 'waking' of the varicella-zoster virus. Based on neurons generated from human embryonic stem cells, and not requiring the use of experimental animals, the model allows scientists to test drugs and develop therapies to prevent shingles. It may also contribute to the fight against other viruses -- such as herpes and polio -- that target the human nervous system. (2015-06-04)

(2015-05-26)

New findings about mechanisms underlying chronic pain reveal novel therapeutic strategies
Canadian neuroscientist Michael Salter and his team have uncovered a critical role for a class of cells present in the brain and spinal cord, called microglia, in pain. They have found microglia to neuron signaling to be crucial in the development of pain hypersensitivity after injury, but also for one of the paradoxical effects morphine and other opioids sometimes produce, called hyperalgesia, which is an increase in pain sensitivity.

Blood to feeling: McMaster scientists turn blood into neural cells
Stem cell scientists at McMaster can now directly convert adult human blood cells to both central nervous system (brain and spinal cord) neurons as well as neurons in the peripheral nervous system (rest of the body) that are responsible for pain, temperature and itch perception. This means that how a person's nervous system cells react and respond to stimuli, can be determined from his blood. (2015-05-21)

Human stem cell model reveals molecular cues critical to neurovascular unit formation
Using human embryonic stem cells, researchers at University of California, San Diego School of Medicine and Moores Cancer Center and Sanford-Burnham Medical Research Institute created a model that allows them to track cellular behavior during the earliest stages of human development in real-time. The model reveals, for the first time, how autonomic neurons and blood vessels come together to form the neurovascular unit. (2015-05-21)

Nerve cells use each other as maps
When nerve cells form in an embryo they have to be guided to their final position by navigating a kind of molecular and cellular 'map' in order to function properly. In a recent research study published in Nature Communications neurobiologist Sara Wilson, Umeå University in Sweden, found that during embryonic development different parts of the nerve cell are important for guiding other nerve cells into their physical positions. (2015-05-19)

Scientists unravel the mystery of the tubulin code
Driving down the highway, you encounter ever-changing signs -- speed limits, exits, food and gas options. Seeing these roadside markers may cause you to slow down, change lanes or start thinking about lunch. In a similar way, cellular structures called microtubules are tagged with a variety of chemical markers that can influence cell functions. The pattern of these markers makes up the 'tubulin code' and scientists have uncovered the mechanism behind one of the main writers of this code. (2015-05-12)

Deciphering the neural code that links food to aging
Diet exerts a major impact on health and aging. The nervous system plays an important role in this process but, thus far, how food signals are interpreted by the nervous system has been a mystery. A new study has found that serotonin and TGF-beta hormone levels in specific neurons of C. elegans communicate information about food abundance in roundworms. These signals from the nervous system influence the animal's lifespan, thus mediating the effects of food on aging. (2015-05-12)
