Ibits LPS-stimulated microglia activation via collective regulation of JNK1/2 and ERK1/2 signaling. Our outcomes indicate a potential part of paroxetine in neuroprotection through its anti-neuroinflammatory effect besides targeting for depression. Keywords and phrases: Paroxetine, Microglia, Lipopolysaccharide, Neuroinflammation, MAPKIntroduction Parkinson’s disease (PD) would be the second most typical neurodegenerative disease characterized by a dramatic loss of dopaminergic neurons in substantia nigra. Though the etiology of PD along with the underlying mechanisms for disease development remain incompletely understood, growing evidence has recommended that inflammatory processes* Correspondence: zhangxiong98@gmail; jianhong.zhu@gmail Equal contributors 1 Division of Neurology Geriatrics, the Second Affiliated Hospital, Wenzhou Medical University, Wenzhou, Zhejiang 325000, China 2 Department of Preventive Medicine, Wenzhou Medical University, Wenzhou, Zhejiang 325035, Chinaplay a crucial function within the pathogenesis of PD [1-3]. Microglia would be the resident macrophages on the central nervous program and act as the prime effector cells in mediating neuroinflammation [4,5]. It has been suggested that inflammatory mediators including nitric oxide (NO), TNF-, and IL-1 derived from microglia are involving within the progression of neuronal cell death in PD [6,7]. Certainly, lipopolysaccharide (LPS) as an inflammation elicitor has usually been made use of to generate phenotypes of PD in animals [8,9]. Therefore, modulation of microglial activation and its production of pro-inflammatory mediators and cytokines will be a promising tactic to alleviate the progression of PD.?2014 Liu et al.; licensee BioMed Central Ltd.
