IL-37 is increased in the brain after stroke in a human and in IL-37tg mice, and is associated with a lower median clinical score in mice. Photomicrographs showing IL-37 immunoreactivity is (a) absent in a brain section from the contralateral hemisphere and (b) present (arrows) in the ischemic hemisphere of a stroke patient. Scale bar = 100 µm. (c) Expression of IL-37 mRNA in brains of IL-37tg mice 24 h after sham surgery (n = 8) or in the ischemic hemisphere after stroke (n = 13). The mean of the sham group is set as 1.0. **P < 0.01; Welch’s t-test. (d) Clinical score for wild-type (WT; n = 12) and IL-37tg mice (n = 13) at 24 h after stroke (P = 0.747; Mann-Whitney test). Data in (c,d) are presented as mean ± S.E.M. or median, respectively.
