IL-33 isoforms. Interleukin-33 in serum (a–c) and CSF (d) samples of representative AD, MCI, and HC individuals. A 30-kDa band corresponding to the full-length IL-33 protein was detected in all cases. An additional 20-kDa band was also present in two cases. Human recombinant artificial truncated IL-33 (amino acids 112–270, 20 kDa) was used as a positive control (Ctrl); a pre-stained marker was also used. Broad range 11–190 kDa
