Although the specific cellular mechanisms underlying neuropathic pain remain poorly understood, the production of inflammatory cytokines in the spinal cord is regarded as a key factor.1,2 It has been reported that the interleukin (IL)-1 superfamily cytokines, such as IL-1β and IL-18, are actively involved in neuropathic pain through their specific receptors.3 As a novel member of the IL-1 superfamily, IL-33 has attracted growing interest since its discovery in 2003.4 Similar to IL-1α, IL-33 functions both as a traditional cytokine and a nuclear factor.. In the cell nucleus, IL-33 may act as a transcriptional repressor.5 As a cytokine, IL-33 is released from the nucleus to alert the immune system to tissue damage or stress.6 IL-33 exerts its biological effects by binding to its receptor complex, which is composed of ST2 (IL-1RL1) and IL-1 receptor accessory proteins.7 The effects of IL-33 are either proinflammatory or antiinflammatory depending on the disease.8 Notably, studies have suggested that IL-33 plays an important role in the modulation of inflammatory What We Already Know about This Topic |
![Summary of interleukin‐33 (IL‐33) actions in psoriatic inflammation. IL‐17‐producing T cells [T helper type 17 (Th17), IL‐17‐producing γδT (γδT17) and IL‐17‐producing CD8+ T (Tc17) cells] produce and secrete large amounts of IL‐17A under the inflammatory microenvironment of psoriasis. Then IL‐17A acts on keratinocytes to promote the IL‐33 expression. On the one hand, the increased IL‐33 from keratinocytes or other cells in the dermis, such as fibroblasts, can promote the proliferation of keratinocytes to aggravate the psoriatic inflammation, but on the other hand, inhibit the differentiation and function of Th17 cells to remit the psoriatic inflammation](https://pub-med-central-images-cdn.bioz.com/pub_med_central_ids_ending_with_0137/pmc07370137/pmc07370137__IMM-160-382-g005.jpg)
