Microglial activation has been implicated in various neurological disorders, including Alzheimer's disease, Parkinson's disease, multiple sclerosis, and HIV encephalopathy. Phytoestrogens have been shown to be neuroprotective in neurotoxicity models; however, their effect on microglia has not been well established. In the current study, we report that the(More)
6-Hydroxydopamine (6-OHDA) selectively enters dopaminergic neurons and undergoes auto-oxidation resulting in the generation of reactive oxygen species and dopamine quinones, subsequently leading to apoptosis. This mechanism mimics the pathogenesis of Parkinson's disease and has been used to induce experimental Parkinsonism in both in vitro and in vivo(More)
Oxidative stress (OS) plays a pivotal role in the pathogenesis of Parkinson's disease (PD). 6-Hydroxydopamine (6-OHDA) is a neurotoxin used to induce oxidative cell death of dopaminergic neurons in experimental models of PD. Curcumin I, or diferuloylmethane is a pure compound isolated from Curcuma longa Linn. that has been reported to have neuroprotective(More)
Methamphetamine (METH) is a highly addictive CNS stimulant that its long-term use is associated with the loss of neurons in substantia nigra and development of Parkinson’s disease later in life. Common form of METH is Ya-Ba tablet, in which, large portion of caffeine is added to the mass to enhance the stimulatory effect. Previous study demonstrated that(More)
Overproduction of pro-inflammatory mediators resulting from chronic activation of microglia has been implicated in many neurodegenerative disorders, such as Parkinson's disease and Alzheimer's disease. In this study, we investigated the effects of (3R) 1,7-diphenyl-(4E,6E)-4,6-heptadien-3-ol, or compound 049 on the production of pro-inflammatory mediators(More)
OBJECTIVE We investigated the molecular mechanisms underlying the effect of (3S)-1-(3,4-dihydroxyphenyl)-7-phenyl-(6E)-6-hepten-3-ol, also known as compound 092, isolated from Curcuma comosa Roxb on the production of pro-inflammatory mediators and oxidative stress in lipopolysaccharide (LPS)-activated highly aggressive proliferating immortalized (HAPI)(More)
