Laboratory tests of a novel serotonin-binding compound have revealed an unexpected disconnect between receptor activation and ...

A bitter taste has always been considered a warning signal, devoted to protecting us from ingesting potentially harmful ...

In the cerebral cortex, extrinsic and intrinsic excitatory glutamatergic pathways terminate on principal glutamatergic neurons and local inhibitory GABAergic interneurons. Activation of these pathways ...

The new 12-month project extends a prior two-year award for which Habegger studied mechanisms of glucagon, Glucagon-like peptide-1 (GLP-1), and glucose-dependent insulinotropic polypeptide (GIP) and ...

Researchers at the University of North Carolina (UNC) at Chapel Hill School of Medicine have revealed the detailed structure of the bitter taste receptor, a protein called TAS2R14, and have shown ...

Prostaglandin E 2 (PGE 2), a bioactive lipid derived from arachidonic acid, mediates a broad range of physiological processes through four G protein-coupled receptor (GPCR) subtypes: EP1–EP4. While ...

Scientists have discovered that T cell receptors activate through a hidden spring-like motion that had never been seen before. This breakthrough may help explain why immunotherapy works for some ...

Drug discovery is shifting from static snapshots to moving pictures. Instead of inferring how medicines work from end results, researchers are now watching individual molecules collide with cell ...
