Figure 2: The expression levels of inflammatory factors in AD and control groups. (a) No significant difference was detected for the expression levels of IL6, TNF-α, IL1-β, and IL10 in peripheral blood of AD and control groups (p>0.05) (n = 6/group). (b) The expression levels of IL6, TNF-α, IL1-β, and IL10 in cerebrospinal fluid were significantly different from that in peripheral blood of AD group (p>0.05) (n = 6/group). Data are expressed as the mean ± standard error of the mean (SEM).
