Scientists provide insight into the molecular mechanisms behind Listeria monocytogenes

When the bacterium Listeria monocytogenes invades the body, it commandeers its host cell's actin cytoskeleton to invade other cells. In a report published in the Journal of Biological Chemistry, a group of scientists provide insight into the molecular mechanisms behind this infection technique.

New center focuses on rare Batten disease

For children with Batten disease and their families, the cruelty of the disease, which robs children of their sight, their cognitive faculties and finally their lives, is made worse by the hunt for a doctor experienced at recognizing and treating patients.

Mountaineering doctors hike medicine to new heights with Xtreme Everest

Doctors working at the edge of extreme are set to climb the world’s tallest mountain to look death in the face – and take its pulse. The medical research team will make the first ever measurements of blood oxygen in the ‘death zone’, at altitudes above 8,000 metres where the human body has struggled - and frequently failed - to survive.

Lack of sleep activates the body’s defence mechanisms

A lack of sleep is considered a threat situation, which activates the body’s defence mechanisms. This is the same type of response that protects the body against viruses and bacteria as well as in stress situations.

Study reveals how brain's immune system fights viral encephalitis

The findings, published as the cover study in the latest issue of Virology, show that proteins in neurons fight the virus at multiple stages - by preventing the formation of viral RNA and proteins, and blocking the virus' release, which could infect other cells in the brain.

Q. What turns an obese person into a person with diabetes? - A. Leptin

Twin epidemics of obesity and type 2 diabetes are bearing down on the world's population, threatening the lives of hundreds of millions of people. But scientists are still trying to determine how the two conditions are linked, and what it takes to turn an obese person into a person with diabetes.

Neuronal death and processing of Tau protein in Alzheimer’s Disease (AD)

In a research report recently published in the Journal of Alzheimer's Disease, published by IOS Press, a research group from the International School for Advanced Studies (ISAS\SISSA) in Trieste (Luisa Fasulo, Gabriele Ugolini e Antonino Cattaneo) showed that a processed form of tau protein induces neuronal death by apoptosis (programmed cell death) when expressed in cultured rat hippocampal neurons.
