Opioid receptors in motion: new clues for safer painkillers
Understanding the moving target: mu-opioid receptors For decades, scientists have known that opioids relieve pain by binding to mu-opioid receptors in the brain. These molecular switches, when activated, set off a cascade of signals that dull the perception of pain. But the exact sequence of events inside the receptor remained murky. A recent wave of…
