How a small molecule halts the spread of a toxic protein associated with Alzheimer’s progression

03.05.2018 Health Problems

Alzheimer’s disease destroys brain cells in part by promoting the formation of insoluble clumps that contain a protein called tau. Not only are these “tau aggregates” toxic for the cells that harbor them, but they also invade and destroy neighboring brain cells, or neurons, which speeds the cognitive decline associated with the Alzheimer’s. For those reasons, Alzheimer’s researchers have been […]

Researchers map the potential spread of yellow fever virus to cities around the world

Research finds new mechanism that can cause the spread of deadly infection

20.04.2018 Health Problems

Scientists at the University of Birmingham have discovered a unique mechanism that drives the spread of a deadly infection. Cptococcosirys is a rare and deadly fungal infection that affects the lung and brain and usually only occurs in people with impaired immunity. However, one strain of the fungus – known as the Pacific Northwest strain of Cryptococcus gattii – has […]
