Increased levels of serum cytokines in mice with post-ischemic heart failure. Real-time multiplex of (A) Th1-related cytokines (IL-1β, IFN-γ, TNF-α, and IL-12), (B) Th2-related cytokines (IL-4, IL-6 and IL-10), and (C) chemokines (KC and MCP-1) in circulating plasma from control (Ct), sham-operated (Sh) and heart failure (HF) mice, 7 weeks after surgery. Data are reported as means ± SD of at least 5 mice per group. *P < 0.05 (Kruskal-Wallis test).
