Organophosphates (OPs) pose a constant threat to human health due to their widespread use as pesticides and their potential employment in military and terrorist attacks. The acute toxicity of OPs has been extensively studied; however, the consequences of prolonged or repeated exposure to levels of OPs that produce no overt signs of acute toxicity (i.e.(More)
The mu opioid receptor plays an important role in mediating the actions of morphine and morphine-like drugs. Receptor binding and a wide range of pharmacological studies have proposed several mu receptor subtypes, but only one mu opioid receptor (Oprm) gene has been isolated. Like the mouse and rat, the human Oprm gene undergoes alternative splicing. In the(More)
The differential distribution of NMDA receptor subunit mRNAs in the developing mammalian cerebellum has been previously described. In this study, we investigated the temporal expression of NMDA receptor proteins in the postnatal murine cerebellum using antibodies specific for the NMDA zeta 1 and NMDA epsilon subunits. Our results showed a gradual increase(More)
The N-methyl-D-aspartate receptors have been implicated in neuronal plasticity and their overactivation leads to neurotoxicity. Molecular cloning and co-expression of various glutamate receptor zeta and epsilon complementary DNAs support a heteromeric structural organization for N-methyl-D-aspartate receptors. In this study, we show that cerebellar granular(More)
