A team of researchers from the University of Castilla-La Mancha, Spain, further investigated the link between hippocampal G protein-activated inward rectifier potassium channel (GIRK) and Alzheimer’s disease pathology.

“Loss of synapses and dysfunctional synapses in a region-specific way is important in Alzheimer’s. It’s actually the strongest correlate of cognitive decline, far more so than plaques and tangles, which are the pathological hallmarks,” Soyon Hong told the audience at the XVII Meeting on Glial Cells in Health and Disease, which was held in Marseille last week.

At first blush, the brain’s extracellular matrix (ECM) seems like the opposite of synaptic plasticity. Plasticity is the ability to change; the ECM is stable, to the point that it is often described as a scaffold – something to lend stability. “ECM proteins have some of the longest lifetimes of any protein in the brain,” Anna Molofsky told her audience at the XVII Meeting on Glial Cells in Health and Disease, which is being held in Marseille this week.

FAST kinase domain-containing protein 5 (FASTKD5) is a mitochondrial protein that is needed for processing mRNA in the primary mitochondrial transcript. Several mutations have been found in other proteins involved in mitochondrial metabolism, but mutations in the FASTKD5 gene have not yet been reported.

Progenra Inc. reports that it has discovered a new class of small-molecule PINK1 activators that restore function in mutant forms of the PINK1 kinase, a key mitochondrial regulator whose dysfunction leads to familial or early-onset Parkinson’s disease (PD).

Qanatpharma AG (QP), Zuse Institute Berlin (ZIB), Enamine Ltd. and Proteros biostructures GmbH have announced the launch of a research collaboration to accelerate the discovery of novel therapeutics targeting cerebral perfusion deficits associated with subarachnoid hemorrhage (SAH).

The U.S. FDA has granted orphan drug designation to Klotho Neurosciences Inc.’s secreted-Klotho (s-KL) promoter, gene and delivery system (KLTO-202 or s-KL-AAV.myo) for the treatment of amyotrophic lateral sclerosis (ALS).
