Neuroinflammation in Neurodegeneration
Alzheimer's Disease Neuroinflammation is a hallmark of AD pathophysiology[@wang2015]:
Microglial activation : Chronic activation of brain immune cellsCytokine release : IL-1β, IL-6, TNF-α elevationComplement activation : C1q, C3 involvement in synaptic lossTREM2 genetics : TREM2 variants increase AD riskParkinson's Disease PD shows significant neuroinflammatory components[@hirsch2009]:
Microglial activation : Evident in substantia nigraPeripheral inflammation : Systemic inflammatory markers[NLRP3 inflammasome](/entities/nlrp3-inflammasome) : Activation in PD modelsLocus coeruleus : Noradrenergic inflammation modulationALS ALS demonstrates prominent neuroinflammation[@beers2008]:
Microglial heterogeneity : Distinct activation statesAstrogliosis : Reactive astrocyte responsesPeripheral immune : T cell involvementNLRP3 activation : Inflammasome in motor neuron diseaseKey Players
