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

Inositol phosphates are crucial secondary messengers that modulate a wide range of cellular processes, from energy metabolism to gene expression. These molecules, particularly inositol pyrophosphates, ...

A new study discovers how nitric oxide triggers a biochemical domino effect in the brain, leading to mTOR overactivation in ...

Think of the brain as a city with traffic lights that keep signals flowing smoothly. In a new study, researchers followed a clue about nitric oxide, a common chemical messenger, and found that, in ...

A hidden molecular chain reaction in the brain may push key cellular systems into overdrive in autism—and scientists just ...

Spinal cord injury often triggers a cascade of secondary damage that severely limits functional recovery, largely driven by ...

Ribosomes don’t just make proteins—they can sense when something’s wrong. When they collide, they send out stress signals that activate a molecule called ZAK. Researchers uncovered how ZAK recognizes ...

In a discovery that could guide the development of next-generation antidepressants and antipsychotic medications, researchers at the Icahn School of Medicine at Mount Sinai have developed new insights ...

Sepsis and severe pneumonia are frequently accompanied by disruption of the gut microbiota, leading to immune dysfunction and ...

Post-traumatic osteoarthritis often affects younger, active individuals and progresses quickly following ligament or ...
