Journal ArticleDOI

Dopamine- or L-DOPA-induced neurotoxicity: the role of dopamine quinone formation and tyrosinase in a model of Parkinson's disease.

TL;DR: The double-edged synthesizing and oxidizing functions of tyrosinase in the dopaminergic system suggest its potential for application in the synthesis of DA, instead of TH in the degeneration of dopamine neurons, and in the normalization of abnormal DA turnover in long-term L-DOPA-treated Parkinson's disease patients.
Journal ArticleDOI

Pole test is a useful method for evaluating the mouse movement disorder caused by striatal dopamine depletion

TL;DR: The pole test appears to be useful in predicting the extent of the lesion to select a mouse in which the receptive fields of the dopaminergic cells are denervated, and shows that presynaptic neuroadaptations and behavioral recovery exist in this animal model.
Journal Article

A simple quantitative bradykinesia test in MPTP-treated mice.

TL;DR: It is suggested that MPTP-treated mice are a useful experimental model for the study of parkinsonism, and that the pole test using these animals is of value in the screening of anti-parkinsonian agents.
Journal ArticleDOI

Expression of toll-like receptor 2 on CD16+ blood monocytes and synovial tissue macrophages in rheumatoid arthritis

TL;DR: The results suggest that CD16+ monocytes and synovial tissue macrophages with high TLR-2 expression may be induced by M-CSF and IL-10, and their production of TNFalpha could be simulated by endogenous TLR ligands such as Hsp60 and FcgammaRIIIA ligation by small immune complexes in RA joints.
Journal ArticleDOI

Dopamine D2 receptor-mediated antioxidant and neuroprotective effects of ropinirole, a dopamine agonist

TL;DR: In vitro free radical scavenging and antioxidant activities of ropinirole, a non-ergot DA agonist, as well as its glutathione, catalase and superoxide dismutase activating effects and neuroprotective effect in vivo are assessed to indicate that activation of GSH, catAlase and SOD mediated via DA D2 receptors may be the principal mechanism of neuroprotection by roPinirole.
