    • Bio Activity:

      <p>Nociceptin is a 17-amino acid neuropeptide which is the endogenous ligand for the nociceptin (NOP) receptor (previously known as ORL1). Nociceptin shows no activity at the classical &mu;, &delta; or &kappa; opioid receptors.</p> <p><br />The neuropeptide is active in vivo and is involved in a variety of physiological processes. For example, it has been shown to be involved in pain, anxiety, depression, obesity, addiction, hyperphagia, Parkinson&rsquo;s ,cognition, cardiovascular, inflammatory and learning and memory.</p> Hello Bio [HB2424]
