Abstract
BackgroundAmyloid β-protein(Aβ) can be aggregated and deposited in the extracellular space as plaques, it is well-known that Aβ-toxicity is related to the progression of cognitive impairment.
ObjectiveTo provide the insight of the role of microglia in cognitive impairment induced by Aβ.
ContentMicroglia could be activated to be classic active state (M1 state) or alternative active state (M2 state). The microglia in the former state can induce neuro-inflammation by secreting inflammatory cytokines, such as IL-1β, IL-6 and TNF-α etc. Thus to damage the neurons and synaptic plasticity, leading to cognitive dysfunction. Shifting microglial M1 to M2 state could be considered to be an effective therapy for Aβ related cognitive impairment.
TrendAt present, there are many studies focus on regulating the M1/M2 phenotype of Aβ-activated microglia, but the precise orientated regulation needs to be studied deeply. The regulation of microglia polarity is expected to be the target of Aβ-related cognitive impairment treatment.
Key words:
Microglia; Amyloid β-protein; Cognitive impairment
