Striatal dopamine levels and changes in mitochondrial function following chronic 3-nitropropionic acid treatment in rats
An irreversible inhibitor of complex II in the mitochondria, 3-nitropropionic acid (3-NP), induces bilateral striatal lesions with many neuropathological features of Huntington’s disease (HD) in rats. It is widely used as a model of HD. Chronic systemic treatment of 3-NP for 4 days in rats (10, 15 and 20 mg/kg) caused a significant dose-dependent reduction in succinate dehydrogenase activity, w...

متن کاملD1-like dopaminergic activation of phosphoinositide hydrolysis is independent of D1A dopamine receptors: evidence from D1A knockout mice.
Accumulated evidence suggests that dopamine and dopamine D1 agonists can activate phospholipase C in both brain and peripheral tissue. The receptor that mediates the hydrolysis of phosphoinositides has not been identified. The cloned dopamine D1A receptor that is generally thought to be linked to adenylyl cyclase, has also been proposed to couple to phospholipase C. However, a number of studies...
متن کاملAltered dopamine release and uptake kinetics in mice lacking D2 receptors.
Dysregulation of dopamine transmission is thought to contribute to schizophrenic psychosis and drug dependence. Dopamine release is regulated by D2 dopamine autoreceptors, and D2 receptor ligands are used to treat psychosis and addiction. To elucidate the long-term effects of D2 autoreceptor activity on dopamine signaling, dopamine overflow evoked by single or paired-pulse stimulation was compa...
متن کاملAltered Receptors
Receptor disorders may produce specific clinical manifestations resembling hypo-or hyper-function of related endocrine gland. Receptor disorders can be divided into five categories: 1)Altered receptor concentration exists in insulin resistance seen in obsity, familial hypercholesterolemia and in testicular feminization. 2) Altered receptor affinity can be seen in fasted obese patients, acromeg...
