New molecular insights into the link between hepatocellular carcinoma and intratumoral fibrosis could lead to better ...

Researchers identified in mice a microbiome–gut–brain pathway in which age-associated changes in gut microbes increase medium-chain fatty acids that impair vagal sensory signaling and hippocampal ...

How do blood vessels stay strong, flexible, and responsive to the body's changing need for oxygen and nutrients? The answer lies not only in biology—but also in physics. Researchers at Åbo Akademi ...

Restoring the gut microbiota through fecal microbiota transplantation reversed these effects. The treatment replenished CX3CR1-positive NK cells, reduced lung damage, and improved survival. Targeted ...

Dental pulp injury caused by trauma or deep caries often leads to inflammation, tissue necrosis, and eventual loss of tooth ...

Northwestern Medicine scientists have discovered how calcium signaling channels in microglia—the primary immune cells of the brain—regulate neuroinflammation and promote the development of behaviors ...

Dental pulp regeneration remains a major clinical challenge. Researchers have discovered that SMAD7 directly forms a ...

A wave of recent neuroscience research has identified specific molecular and cellular mechanisms through which alcohol disrupts signaling between brain cells, offering a sharper picture of how ...

Researchers have uncovered a surprising molecular chain reaction in the brain that may play a role in some forms of autism.
