However, the regulatory mechanisms between cholinergic and opioidergic system have not been well characterized. In the present study, we investigated whether there are compensatory changes of acetylcholinesterase activity and cholinergic receptors in mice lacking mu-opioid receptor gene. The acetylcholinesterase activity was determined by histochemistry assay. The cholinergic receptor binding was carried out by quantitative autoradiography using [3H]-quinuclidinyl benzilate (nonselective muscarinic receptors), N-[3H]-methylscopolamine (nonselective muscarinic receptors), [3H]-pirenzepine (M1 subtype muscarinic receptors) and [3H]-AF-DX384 (M2 subtype muscarinic receptors) in brain slices of wild-type and mu-opioid receptor knockout mice. The acetylcholinesterase activity of mu-opioid receptor knockout mice was higher than that of the wild-type in the striatal caudate putamen and nucleus accumbens, but not in the cortex and hippocampus areas. In addition, the bindings in N-[3H]-methylscopolamine and [3H]-AF-DX384 of mu-opioid receptor knockout mice were significantly lower when compared with that of the wild-type controls in the striatal caudate putamen and nucleus accumbens. However, there were no significant differences in bindings of [3H]-quinuclidinyl benzilate and [3H]-pirenzepine between mu-opioid receptor knockout and wild-type mice in the cortex, striatum and hippocampus. These data indicate that there are up-regulation of acetylcholinesterase activity and compensatory down-regulation of M2 muscarinic receptors in the striatal caudate putamen and nucleus accumbens of mu-opioid receptor knockout mice."xsd:string |
