...rses atherosclerosis In animals and humans, the proteins known as liver X receptors (LXRs) sense cholesterol levels. Upon sensing increases in cholesterol, these receptors activate signaling pathways that remove diet-derived cholesterol from the body. Two types of LXRs LXR-alpha and LXR-beta are therefor...

Scratch no more: Gene for itch sensation discovered

...ional itch receptors," Chen says. "We know of some proteins that are similar to GRPR, so now we're trying to determine if there is functional redundancy in the itching pathway." GRPR knockout mice had normal reactions to painful stimuli, indicating that pain and itch are mediated by separate sets of genes in ...

Steroids, not songs, spur growth of brain regions in sparrows
