T cell activation—the process by which these key immune defenders recognize threats and mobilize against them—depends on exquisitely timed molecular signals. Now researchers have captured one of the ...

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

Photoreceptors are specialized cells in the eye that convert light energy into neural signals. Several diseases that cause irreversible vision loss, including age-related macular degeneration, ...

Researchers discovered immune cell aggregates in the gut may signal blood vessel cells and fibroblasts to produce excess collagen, driving fibrosis in Crohn’s disease. The findings could guide ...

Innate immune sensors – known as pattern recognition receptors (PRRs) – detect specific molecular components of bacterial or ...

A newly identified role for the neuronal MPS shows it controls nutrient uptake by acting as a gatekeeper. Its disruption ...

A new study shows cells use dual RNA signals to control microRNA lifespan. This selective process protects gene regulation ...

Garlic compounds prolong life and preserve memory and strength in mice, revealing a potential ally against aging.

Researchers have identified a specific hormone produced by pancreatic beta cells as a direct driver of obesity-linked ...

A lipid hidden within cells called phosphatidylserine reveals how the body initiates the removal of threats and cellular debris.

The vagus nerve is a direct link between the gut and brain. Scientists have now used a mouse model to show that changes in gut bacteria could be ... | Microbiology ...

Scientists are investigating how exercise-triggered stress reshapes the cell’s energy systems, and whether those same mechanisms could eventually help counter metabolic disease. Don’t like the gym?
