Dendorbium Nobile Lindl. Alkaloids Suppress NF-kB and NLRP3 Signaling Pathways to Attenuate Lipopolysaccharideinduced Neuroinflammation

Alzheimer’s disease (AD) is the most common brain disease with aging characterized by progressive memory loss and cognitive decline. The hallmark of AD is the formation of senile plaques composed of amyloid-β (Aβ) and neurofibrillary tangles (NFTs). Accumulating evidence indicates that neuroinflammation is also a critical hallmark of AD [1]. Microglia are the major regulators of neuroinflammation in mammalian brain and play a pathological role in AD development and progression [2]. Macroglia could degrade Aβ to resist its deposition, on the other hand, microglia can release proinflammatory mediators to cause neuroinflammation and aggravate Aβ and tau pathology [3-5].
