Figure 2: Role of OmpK36 in serum cytokines TNF-α, IL-1β, IL-6 and IL-10 secretion. The wild-type NVT-1002 can elevate the serum cytokines significantly including TNF-α, IL-1β, IL-6 and IL-10, while the ΔOmpK36 can only enhance IL-1βexpression. The value was mean ± standard error of mean (SEM) at 3, 24, 48 and 72 hours of reaction, n=5.
