Variability in susceptibility to diseases is a well known phenomenon that has been attributed to genetic and environmental factors. At the level of the immune system, the reactivity of two types of T helper cells (Th1 and Th2 cells) plays an important role in determining disease susceptibility.
1. The aims were to study the sulfation of R-(-)-apomorphine (hereafter apomorphine) in the human liver and duodenum, and to study the rate of inhibition of apomorphine sulphation by mefenamic acid, salicylic acid and quercetin also in the human liver and duodenum. 2. A rapid and sensitive method
Introduction: Heterogeneity of symptoms and individual variability of progression characterizes Parkinson's disease. Unmet therapeutic needs include a cure, disease modification, and improvement of available marketed dopamine-substituting
Inflammation has been reported to be closely related to exaggeration of cerebral ischemia and neurodegenerative diseases. Microglia, resident immune cells in the central nervous system, can be activated in response to neuronal injury and produce proinflammatory cytokines, resulting in further
Studies have shown that inflammation and neurodegeneration may accompany the development of addiction to apomorphine and that the glutamate NMDA receptor antagonist, memantine, may be neuroprotective. The similarity between apomorphine and dopamine with regard to their chemical, pharmacological and
Several lines of evidences have shown the inversion association between coffee consumption and Parkinson's disease (PD) development. Caffeine is a methylxanthine known as a non-selective inhibitor of A2A and A1 adenosine receptors in the brain and shown to be a neuroprotective drug. The objectives
Infusion site reactions are common following subcutaneous infusion of drugs. Such reactions can lead to discontinuation of the treatment. Therefore, assessment of such reactions is essential during preclinical safety studies, and magnetic resonance imaging (MRI) can assist in evaluation. Here, in
To establish the possible roles of oxidative stress, inflammatory processes and other unknown mechanisms in neurodegeneration, we investigated brain gene alterations in N-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) mice model of Parkinson's disease using Atlas mouse cDNA expression array
Schizophrenia is known to be associated with metabolic disturbances including diabetes mellitus, obesity and cardiovascular diseases. A growing body of evidence has suggested abnormal cytokine levels in schizophrenia. In the present study, we explored the effects of low-grade chronic inflammation on
Accumulating clinical and experimental evidence suggests that chronic neuroinflammation is associated with dopaminergic neuronal death in Parkinson's disease (PD). Ginsenoside Rg1, the most active components of ginseng, possesses a variety of biological effects on the central nervous system,
Pentoxifylline (PTX) is a phosphodiesterase inhibitor with anti-TNF-alpha activity, associated with its anti-inflammatory action. Considering Parkinson's disease (PD) as a neuroinflammatory disorder, the objectives were to evaluate PTX neuroprotective properties, in a model of PD. Male Wistar rats,
Preparations of Ficus platyphylla are used in Nigeria's folk medicine to manage a plethora of diseases including, insomnia, psychoses, depression, epilepsy, pain and inflammation. In this study, we examined the effects of the standardized methanol extract of F. platyphylla stem bark (FP) on
Complete Freund's adjuvant (CFA), a pro-inflammatory agent, was inoculated, subcutaneously, to Sprague-Dawley rats prior to the intrastriatal injection of 6-hydroxydopamine (6-OHDA). Animals were sacrificed 7 and 28 days following 6-OHDA injection; neuronal damage, glial activation and cytokine
