IL10 and congestive heart failure: ELISA assays showed IL-10 and TGF-β level in CHF patients plasma were both significantly elevated compared to the normal control (∗∗P < 0.01) (IL-10: 36.84 ± 5.42 vs. 22.21 ± 3.26 pg/mL, n = 30; TGF-β: 5131.25 ± 829.65 vs. 1775.83 ± 541.16 pg/mL, n = 30) (Figure 2A).
