Western blot analyses for serum in CHF patients, non-CHF patients, and HC. IL-33 in serum was collected by immunoprecipitation, which was subsequently subjected to western blotting for analyzing the exact form of IL-33 in serum. Total IL-33 contents: ≈2.7 ng in CHF; ≈1.9 ng in non-CHF and ≈ 1.7 ng in HC. c-IL33, cleaved IL-33; f-IL33, full-length IL-33. Other abbreviations are the same as those shown in Table 1.
