The loss of myelin in the cerebral cortex of multiple sclerosis (MS) patients could be recovered if oligodendrocytes, the cells that myelinate neuronal axons, work at a higher rate than they are destroyed. However, a group of scientists from the University of Munich have shown, in cortical MS mice, that this does not occur. The oligodendrocytes do not contribute to remyelination efficiently.

The inhibition of an enzyme associated with neurodegeneration processes reduced the toxic effect of tau, one of the proteins that damage neurons in Alzheimer’s disease (AD). A group of scientists from the University of Helsinki have shown in vitro and in animal models of AD how inhibition of the prolyl endopeptidase (PREP) enzyme reduced tau protein aggregations.

Chronic inflammatory and neuropathic pain are among the most common chronic conditions, but their treatment options present significant limitations both in efficacy and safety. Researchers from Purdue University presented data on their work aimed to develop adenyl cyclase type 1 (AC1, ADCY1) inhibitors as a new treatment for chronic pain.

Researchers from High Point University recently reported the discovery and preclinical evaluation of a novel class of highly selective dopamine D4 receptor-selective ligands as potential therapeutic candidates for substance use disorders.
