Figure 5From: Stimulation of peripheral Kappa opioid receptors inhibits inflammatory hyperalgesia via activation of the PI3Kγ/AKT/nNOS/NO signaling pathway PI3Kγ is expressed in KOR-immunoreactive neurons. Confocal images of anti-PI3Kγ (red, left column) immunoreactivity in a population of DRG neurons from rats labeled with antibodies to KORs (green, middle column). Arrows indicate double-labeled neurons (yellow, right column). Scale bars: 50 μm.Back to article page
