Striatal dopamine D2 receptors in tardive dyskinesia: PET study.

The dopamine D2 receptors were investigated in vivo in eight neuroleptic-free patients with persistent tardive dyskinesia using positron emission tomography and 76Br-bromospiperone. The striatal receptor density, estimated by the striatum/cerebellum radioligand concentration ratio, was not elevated in patients as compared with age-matched controls but was positively correlated with the severity...

the effect of e-64 on the developmental competence of sheep cocs during in vitro maturation

in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.

Differential Dopamine Receptor Occupancy Underlies L-DOPA-Induced Dyskinesia in a Rat Model of Parkinson's Disease

Dyskinesia is a major side effect of an otherwise effective L-DOPA treatment in Parkinson's patients. The prevailing view for the underlying presynaptic mechanism of L-DOPA-induced dyskinesia (LID) suggests that surges in dopamine (DA) via uncontrolled release from serotonergic terminals results in abnormally high level of extracellular striatal dopamine. Here we used high-sensitivity online mi...

Ultrastructural localization of D2 receptor-like immunoreactivity in midbrain dopamine neurons and their striatal targets.

Potential cellular substrates for functions ascribed to the dopamine D2 receptor were examined in rat brain using immunoperoxidase for localization of a D2 receptor peptide and immunogold staining for the catecholamine biosynthetic enzyme tyrosine hydroxylase (TH). Specificity of the rat polyclonal antiserum, raised against a 15 amino acid fragment from the third intracellular loop of the D2 re...
