Alzheimer's disease not only robs people of their memory but also affects mood, often causing anxiety and depression. Until now, scientists haven't fully understood how these symptoms are connected in ...

The gene NPAS3 controls how brain support cells, or astrocytes, generate energy in their mitochondria (shown here). This ...

Astrocytes, a major type of glial cell in the central nervous system (CNS), play a pivotal role in neuronal survival and function. They regulate synaptic formation and function, release neurotrophic ...

Scientists have identified a protective brain pathway that may help slow the progression of Parkinson's disease by strengthening the brain's own dopamine-producing neurons, but the positive effect was ...

Scientists have known for some time that Alzheimer’s disease affects brain regions differently. And they have a detailed understanding of how misfolded tau forms toxic tangles in the brain, impairing ...

Scientists discovered that sleep deprivation damages a key brain circuit responsible for social memory, making it harder to recognize familiar individuals. In laboratory studies, caffeine restored ...

Researchers found that KAT7 promotes CMPK2-driven mitochondrial DNA release in microglia, activating inflammatory cGAS-STING ...

New peer-reviewed research from University College Cork traces how voluntary exercise reshapes tryptophan metabolism through the gut microbiota, lowering a key receptor in the memory center of the ...

Income inequality, a structural property of societies characterized by the unequal distribution of resources, is associated with adverse mental health outcomes during adolescence, which is a sensitive ...

Scientists have long known that stress and addiction travel together, but the biological connection between a hard day and a hard-to-break habit has been far less clear. New research now identifies a ...
