Fig. 1From: CSF evidence of pericyte damage in Alzheimer’s disease is associated with markers of blood-brain barrier dysfunction and disease pathologyCSF soluble PDGFRβ level is increased in Alzheimer’s disease (AD) in relation to CSF markers of BBB leakiness (CSF albumin) and disease pathology (elevated total tau (t-tau) and phosphorylated tau (p-tau)). a Dot plot showing significantly higher levels of CSF sPDGFRβ in AD compared to controls (n = 39 per group) (p = 0.0038). b Dot plot showing CSF albumin level in the AD and controls (p = 0.18). c Scatterplots showing positive correlation between CSF sPDGFRβ and CSF albumin in AD. d–f Scatterplots showing a positive correlation between CSF sPDGFRβ and t-tau and p-tau but not with Aβ42 in AD. In a and b, the bars represent the mean ± SEM. In c–f, the best-fit linear regression line is shown and 95% confidence intervals are superimposed. Each dot represents an individual sample. p < 0.05 was considered statistically significantBack to article page
