traumatic brain injury (tbi) can be caused by a wide variety of stimuli and encompasses a large range of severities. tbi has the potential for long-term and gradually increased susceptibility for behavioral disturbances, seizure disorders or neurodegenerative disease. in the healthy central nervous system (cns), astrocytes play important roles in preserving the homeostasis of ions, transmitters...
AIMS β-amyloid (Aβ) plaques are a key feature of Alzheimer's disease pathology but correlate poorly with dementia. They are associated with astrocytes which may modulate the effect of Aβ-deposition on the neuropil. This study characterised the astrocyte response to Aβ plaque subtypes, and investigated their association with cognitive impairment. METHODS Aβ plaque subtypes were identified in t...
The relevance of astrogliosis remains controversial, especially with respect to the beneficial or detrimental influence of reactive astrocytes on CNS recovery. This dichotomy can be resolved if the mediators of astrogliosis are identified. We have measured the levels of transcripts encoding inflammatory cytokines in injury systems in which the presence or absence of astrogliosis could be produc...
Alzheimer's disease (AD) is a neurodegenerative disorder characterized by progressive decline of cognitive function. Astrogliosis plays a critical role in AD by instigating neuroinflammation, which leads ultimately to cognition decline. We previously showed that the intermediate-conductance Ca2+-activated potassium channel (KCa3.1) is involved in astrogliosis-induced by TGF-β in vitro. In the p...
Astrogliosis has long been recognized in Parkinson's disease (PD), the most common neurodegenerative movement disorder. However, the mechanisms of how astroglia become activated remain unclear. Reciprocal interactions between microglia and astroglia play a pivotal role in regulating the activities of astroglia. The purpose of this study is to investigate the mechanism by which microglia regulat...
Submit Manuscript | http://medcraveonline.com potential proand anti-epileptogenic effects [1,2]. Given that epilepsy can be associated with neurodegeneration, mossy fiber sprouting and changes in receptor and neurotransmitter function, examining the specific role of reactive astrogliosis in epilepsy has been fraught with difficulties. Previously, a transgenic mouse line was generated [3] where ...
Neuroinflammation can lead to either damage of astrocytes or astrogliosis. Astrocyte loss may be caused by cytotoxic T cells as seen in Rasmussen encephalitis, auto-antibodies such as in neuromyelitis optica (aquaporin-4 antibodies), or cytokines such as TNF-α in major depressive disorder. Interleukins-1 and -6 appear to be important molecular mediators of astrogliosis. Chronic focal lesions in...
