TNF and Alzheimer disease: In both PC12 and cortical neuron cellular AD models, supernatant TNF-α (P<0.01) (Figure 5A and E), IL-1β (P<0.001) (Figure 5B and F), IL-6 (P<0.001) (Figure 5C and G), and IL-17 (P<0.01) (Figure 5D and H) levels were attenuated in the miR-inhibitor group compared with the NC-inhibitor.
