Brain pathways that control dopamine release may influence motor control

Within the human brain, movement is coordinated by a brain region called the striatum, which sends instructions to motor neurons in the brain. Those instructions are conveyed by two pathways, one that initiates movement (“go”) and one that suppresses it (“no-go”). In a new study, MIT researchers have discovered an additional two pathways that arise… Continue reading Brain pathways that control dopamine release may influence motor control

Interference of nuclear speckles: A nexus of RNA foci, dipeptide repeats, and mis-splicing in C9ORF72 ALS/FTD

In this issue of Neuron, Wu et al. show that nuclear speckle proteins are sequestered by both nuclear RNA foci and cytoplasmic dipeptide repeat aggregates in C9ORF72-ALS/FTD. Consequently, dysregulation of splicing induces widespread splicing alterations and contributes to neurodegeneration.

[Articles] Safety, tolerability, and efficacy of fasudil in amyotrophic lateral sclerosis (ROCK-ALS): a phase 2, randomised, double-blind, placebo-controlled trial

Fasudil was well tolerated and safe in people with amyotrophic lateral sclerosis. The effect of fasudil on efficacy outcomes should be explored in larger clinical trials with a longer treatment duration, oral administration, and potentially higher dose of the trial drug.
