α-Asarone is an active constituent of Acori Tatarinowii, one of the widely used traditional Chinese Medicine to treat cognitive defect, and recently is shown to promote neurogenesis. Here, we demonstrated that low level (3 μM) of α-asarone attenuated LPS-induced BV2 cell bipolar elongated morphological change, with no significant effect on the LPS-induced pro-inflammatory cytokine expressions. ...
Microglial dynamics and role in the healthy and diseased brain: a paradigm of functional plasticity.
The study of the dynamics and functions of microglia in the healthy and diseased brain is a matter of intense scientific activity. The application of new techniques and new experimental approaches has allowed the identification of novel microglial functions and the redefinition of classic ones. In this review, we propose the study of microglial functions, rather than their molecular profiles, t...
Abstract Increasing evidence suggests that microglial activation is strongly linked to the initiation and progression of Parkinson’s disease. Cell-to-cell propagation ?-synuclein pathology a highlighted feature disease, focus such research has been primarily on neurons. However, recent studies as well data contained herein suggest microglia, primary phagocytes in brain, play direct role spread ...
Microglia are the immune cells of the nervous system, where they act as resident macrophages during inflammatory events underlying many neuropathological conditions. Microglia derive from primitive myeloid precursors that colonize the nervous system during embryonic development. In the postnatal brain, microglia are initially mitotic, rounded in shape (amoeboid), and phagocytically active. As b...
background: recently, much attention has been directed towards considering activated microgelial cells as putative targets for treatment of neurological disorders. migriheal® as a novel herbal remedy was introduced for the treatment of migraine headaches. the previous researches has shown that migriheal® extracts can decrease no in an in vitro inflammatory model. the aim of this study ...
Microglia are the resident macrophages of the CNS, and their functions have been extensively studied in various brain pathologies. The physiological roles of microglia in brain plasticity and function, however, remain unclear. To address this question, we generated CX3CR1(CreER) mice expressing tamoxifen-inducible Cre recombinase that allow for specific manipulation of gene function in microgli...
Activated microglia are thought to undergo apoptosis as a self-regulatory mechanism. To better understand molecular mechanisms of the microglial apoptosis, apoptosis-resistant variants of microglial cells were selected and characterized. The expression of lipocalin 2 (lcn2) was significantly down-regulated in the microglial cells that were resistant to NO-induced apoptosis. lcn2 expression was ...
Glial cells form a network in the central nervous system to support neurons and interact with them. The glia consist essentially of astrocytes that help with the nutrition of neurons and react in some cases of injury, oligodendrocytes that produce myelin, and microglia that are derived from the haemopoietic system and are concerned with the immunological defense of the nervous system. Experimen...
Microglia play important roles in perinatal neuro- and synapto-genesis. To test the role of microglia in these processes during adulthood, we examined the effects of microglia depletion, via treatment of mice with the CSF-1 receptor antagonist PLX5622, and abrogated neuronal-microglial communication in CX3C receptor-1 deficient (Cx3cr1-/-) mice. Microglia depletion significantly lowered spine d...
Sevoflurane is one of the most commonly used volatile anesthetics in clinical practice and often pediatric anesthesia intraoperative maintenance. Microglia exist central nervous system are innate immune cells system. Under external stimulation, microglia divided into two phenotypes: proinflammatory (M1 type) anti-inflammatory (M2 type), maintaining stability through induction, housekeeping, def...
