Consistent with previous results, all nuclear transcription factors and cytokines in the AD model group were significantly increased compared with the normal control group, and the mRNA expression of Th1 (T-bet and IFN-γ) and Th17 (ROR-rt and IL-17A) nuclear transcription factors and cytokines were significantly suppressed in PEW-treated groups compared to the AD model group (Figure 6). The gene discussed is IL17A; the disease is Alzheimer disease.
