Microglia trigger astrocyte-mediated neuroprotection via purinergic gliotransmission
Microglia are highly sensitive to even small changes in the brain environment, such as invasion of non-hazardous toxicants or the presymptomatic state of diseases. However, the physiological or pathophysiological consequences of their responses remain unknown. Here, we report that cultured microglia sense low concentrations of the neurotoxicant methylmercury (MeHg(low)) and provide neuroprotect...
متن کاملCannabinoids in Microglia: A New Trick for Immune Surveillance and Neuroprotection
Microglia are the resident immune cells of the brain, and they are under permanent activity to patrol the cerebral microenvironment. A proper inhibitory feedback onto these cells is critical during both intact and injury conditions. In this issue of Neuron, Eljaschewitsch and colleagues report that such feedback is provided by the endogenous cannabinoid anandamine and CB(1/2) receptor signaling...
متن کاملMicroglia-Mediated Neuroprotection, TREM2, and Alzheimer’s Disease: Evidence From Optical Imaging
Recent genetic studies have provided overwhelming evidence of the involvement of microglia-related molecular networks in the pathophysiology of Alzheimer's disease (AD). However, the precise mechanisms by which microglia alter the course of AD neuropathology remain poorly understood. Here we discuss current evidence of the neuroprotective functions of microglia with a focus on optical imaging s...
متن کاملHuman Microglia Transplanted in Rat Focal Ischemia Brain Induce Neuroprotection and Behavioral Improvement
BACKGROUND AND PURPOSE Microglia are resident immunocompetent and phagocytic cells of central nervous system (CNS), which produce various cytokines and growth factors in response to injury and thereby regulate disease pathology. The purpose of this study is to investigate the effects of microglial transplantation on focal cerebral ischemia model in rat. METHODS Transient middle cerebral arter...
متن کاملA potent antioxidant, lycopene, affords neuroprotection against microglia activation and focal cerebral ischemia in rats.
We investigated the effects of a potent antioxidant, lycopene, on the free radical-scavenging activity as evaluated by the DPPH test and lipid peroxidation in rat brain homogenates as well as nitric oxide (NO) formation in cultured microglia stimulated by lipopolysaccharide. In addition, we also investigated the therapeutic effect of lycopene in attenuating ischemia/reperfusion brain injury ind...
