EV71-infected CD14⁺ cells stimulate cytokine production in vitro. (A) Detection of cytokines in the supernatants of CD14⁺ cells from EV71-infected monkeys (n=3) after 24 h of culturing in vitro. P value vs. control group (the supernatants of CD14⁺ cells from normal monkeys after 24 h of culturing). (B) Detection of cytokines in the supernatants of EV71-infected CD14⁺ cells after 24 h post-infection in vitro. P value vs. control group (the supernatants of normal CD14⁺ cells after 24 h of culturing). The cytokines (IL-4, IL-6, IL-8, IL-10, TNF-α and IFN-γ) were measured using BD System kits in accordance with the section on ‘Materials and methods'. Three independent experiments were performed.
