From: Decreased IL-8 levels in CSF and serum of AD patients and negative correlation of MMSE and IL-1β
Cytokine levels in CSF samples of AD patients compared to controls. Box plots comparing CSF IL-1β, IL-8 and TNF-α levels between AD patients and age-matched controls. a IL-1β levels were not altered in AD patients compared to controls (p = 0.12). b IL-8 levels, by comparison, were significantly reduced in AD patients (p = 0.02). c TNF-α showed no significant difference (p = 0.83). Dark horizontal lines represent the mean, with the box representing the 25th and 75th percentiles of the observed data, the whiskers representing the 5th and 95th percentiles, and outliers represented by dots. P values were calculated using the Mann-Whitney Rank sum test
