  • Although scratching can temporarily reduce the sensation of itch by activating inhibitory neuronal circuits, it also leads to amplification of itching at the level of the brain, exacerbating the itch-scratch cycle. (msdmanuals.com)
  • E2F1 is a well-known cell-cycle regulator implicated in cancer, which we have previously established as a mediator of adipose tissue dysfunction in obesity. (easo.org)
