Abstract:
AIM:To investigate the effects of different muscarinic receptor (M) subtypes in the spinal cord on the scores of naloxone-precipitated morphine-withdrawal symptoms and the changes of nNOS expression in locus coeruleus (LC). METHODS:nNOS immunohistochemistry, intrathecal injection (it), and antisense oligonucleotides (AS-ONs) techniques were used. RESULTS:Intrathecal injection of M2-antisense oligonucleotides (M2-AS) decreased the scores of morphine withdrawal symptoms. M1-AS attenuated morphine-withdrawal symptoms, but the effect was less than that of M2-AS. The expression of nNOS positive neurons in the LC increased in morphine-dependent rats and increased to a greater extent during morphine withdrawal. Intrathecal injection of M2-AS inhibited the increase of nNOS expression in LC during morphine-withdrawal, but there was no effect in case of M1-AS. CONCLUSION:M2 muscarinic receptor of spinal cord mediated the increase of nNOS expression in LC during morphine withdrawal.
