چکیده انگلیسی
As a variant of peptide conantokin-T (con-T), con-T[M8Q] is derived from the venom of Conus tulipa. Our previous study has demonstrated that con-T[M8Q] selectively targets N-methyl-d-aspartate receptor (NMDAR) NR2B subunit. In the present study, we determined the effects of con-T[M8Q] on the expression and development of morphine tolerance using hot plate test and acetic acid writhing test. Our results demonstrated that con-T[M8Q] could efficiently attenuate the expression and development of morphine analgesic tolerance in mice at low doses (5-20Â nmol/kg), and it exhibited more potent effects compared with ifenprodil, a typical small-molecule antagonist of NMDAR. In addition, low doses of con-T[M8Q] (5-20Â nmol/kg) did not cause drug resistance and apparent analgesic activity compared with morphine. Taken together, con-T[M8Q] could be a promising new candidate in attenuating morphine tolerance.
