简介
: The development of tolerance to the analgesic effects of morphine as well as morphine dependence were greatly reduced by co-administration with morphine of GM1 ganglioside, a substance reported to block the translocation of protein kinase C (PKC) from cytosol to membrane of neurons. Rats made tolerant to intrathecal administration of morphine showed increased membrane-bound PKC in the superficial layers (laminae I and II) of the spinal cord dorsal horn but not in deeper layers. This increase was prevented by co-administration with morphine of GM1 ganglioside. These results indicate that the translocation and activation of PKC may be a critical step in the development of opiate tolerance and dependence. Modulation of PKC translocation and activation may prove useful for the management of pain and opiate addiction.
