Interleukin 33 (IL-33), an inflammatory and mechanically responsive cytokine, is
an important component of a TLR4-dependent innate immune process in mucosal
epithelium. Although TLR4 also plays a role in sensing biomechanical stretch, a
pathway of stretch-induced TLR4-dependent IL-33 biosynthesis has not been
revealed. In the current study, we show that short term (6 h) cyclic stretch (CS)
of cultured murine respiratory epithelial cells (MLE-12) increased intracellular
IL-33 expression in a TLR4 dependent fashion. There was no detectable IL-33 in
conditioned media in this interval. CS, however, increased release of the notable
alarmin, HMGB1, and a neutralizing antibody (2G7) to HMGB1 completely abolished
the CS mediated increase in IL-33. rHMGB1 increased IL-33 synthesis and this was
partially abrogated by silencing TLR4 suggesting additional receptors for HMGB1
are involved in its regulation of IL-33. Collectively, these data reveal a
HMGB1/TLR4/IL-33 pathway in the response of respiratory epithelium to mechanical
stretch.
