Killifish model helps unravel molecular events that lead to loss of protein homeostasis during brain aging

Aging is the main risk factor for dementia and Parkinson's disease. As age progresses, toxic protein aggregates pile up in the brain and impair neuronal function.

AFFiRiS AG announces results of phase 1 trial with PD01A in Parkinson's

AFFiRiS AG, a clinical-stage biotechnology company developing novel disease-modifying specific active immunotherapies (SAITs), today announced that detailed results of the phase 1 clinical program with its lead candidate PD01 in early Parkinson's disease (PD) patients were published in the peer-reviewed journal The Lancet Neurology.

Neuroscientist discovers neuronal pulses in the human brain that activate after an injury

A neuroscientist's neon pink arm cast led him and fellow researchers at Washington University School of Medicine in St. Louis to discover previously undetected neuronal pulses in the human brain that activate after an immobilizing illness or injury.

Researchers investigate how neural circuits enable the brain to regulate basal sighing

One group of neurons controls various types of sighing, but they receive their instructions from different areas of the brain depending on the reason for the sigh, according to a study scheduled to publish June 16 in the journal Cell Reports.

Scientists discover unexpected role of heat shock proteins during neuronal differentiation

A research team led by Dr Chaogu Zheng from the School of Biological Sciences at the University of Hong Kong, in collaboration with a team led by Professor Martin Chalfie (2008 Nobel Laureate in Chemistry) from the Department of Biological Sciences at Columbia University, recently discovered an unexpected role of the heat shock proteins, also known as the molecular chaperones, during neuronal differentiation, which refers to the process a neuron takes to acquire its shape and function.

Researchers question the mechanism of retinitis pigmentosa

Researchers who made a knock-in mouse-model of the genetic disorder retinitis pigmentosa 59, or RP59, expected to see retinal degeneration and retinal thinning. As reported in the journal Cells, they surprisingly found none, calling into question the commonly accepted -- though never proved -- mechanism for RP59.
