N6-methyladenosine-modified circRIMS2 mediates synaptic and memory impairments by activating GluN2B ubiquitination in Alzheimer’s disease

mycolabadmin

This research reveals how an abnormal RNA molecule called circRIMS2 contributes to Alzheimer’s disease by damaging brain synapses and impairing memory. Scientists found that circRIMS2 levels are elevated through a chemical modification called m6A methylation, and this causes a cascade of events leading to the destruction of important proteins needed for brain communication. The study shows that blocking this damaging pathway using a specially designed peptide can restore memory and synaptic function in Alzheimer’s disease models, offering hope for new therapeutic approaches.

Deciphering the role of CAPZA2 in neurodevelopmental disorders: insights from mouse models

Scientists studied a gene called CAPZA2 that helps control how brain cells connect to each other. When this gene doesn’t work properly, mice had trouble learning, remembering things, and interacting socially, similar to intellectual disability in humans. The researchers found that the problem happens because the connections between brain cells become abnormal and don’t mature properly. This research helps explain why some people with mutations in this gene have developmental difficulties and could lead to new treatments.
