Neutrophil extracellular traps are induced in a psoriasis model of interleukin-36 receptor antagonist-deficient mice.

ABSTRACT: Loss-of-function mutations in the interleukin (IL)-36 gene IL36RN are associated with psoriasis. The importance of neutrophil extracellular traps (NETs), web-like structures composed of neutrophil DNA, in the pathogenesis of psoriasis has been unclear. Here, we aimed to clarify the role of NET signaling in the deficiency of IL36 receptor antagonist (DITRA). We evaluated the severity of psoriasis-like lesions induced by imiquimod cream treatment in Il36rn^-/- mice. The mRNA levels of psoriasis-related cytokines were measured via real-time reverse transcription polymerase chain reaction, and the effects of Cl-amidine, a peptidyl arginine deiminase 4 (PAD4) inhibitor, on psoriasis-like lesions were evaluated. PAD4 is a histone-modifying enzyme that is involved in NET formation. Psor
