Figure 4: VNS mitigates inflammation in SMI/R injury. (a) Relative mRNA levels of IL-1β, IL-6, and TNF-α in the control, I/R, and I/R+VNS groups. (b, c) Representative blots and relative protein expression of IL-1β, IL-6, and TNF-α among different groups. vs. control group; vs. I/R group. IL-1β: interleukin-1β; IL-6: interleukin-6; TNF-α: tumor necrosis factor-α.
