Scientists have successfully reprogrammed astroglia, a type of brain support cell, into neurons that mimic specific interneurons critical for brain function. By modifying the Ascl1 protein, they increased its efficiency in converting astroglia to neuron-like cells, opening new possibilities for regenerative treatments for brain disorders such as epilepsy.

A new study reveals that ancient viral DNA embedded in the human genome is associated with genetic risk for amyotrophic lateral sclerosis (ALS) and multiple sclerosis (MS). Researchers found specific human endogenous retroviruses (HERVs) that influence susceptibility to these neurodegenerative diseases.

Frequent use of high-potency cannabis leaves unique molecular marks on DNA, particularly affecting genes related to energy and immune function. Researchers found that DNA methylation—an epigenetic modification—differed between frequent cannabis users who had experienced psychosis and those who had not, suggesting a possible genetic link to psychosis risk.

A new study reveals that inflammation and immune system activation are closely linked to major depressive disorder (MDD), particularly in those resistant to standard antidepressants. Researchers analyzed gene expression in people with depression, finding increased immune-related gene activity, especially in those with higher inflammation.
