Mechanisms of non-response to ustekinumab, a biologic targeting IL-23, are currently unclear. Here, the authors show that the transcriptional program regulated by IL-22, an IL-23 responsive cytokine, is enriched in patients with ulcerative colitis unresponsive to ustekinumab and associated with higher colon neutrophil recruitment and activation of upstream IL-22 regulators.
