N2 - IL-31 is a recently identified cytokine with a well-defined role in the pathogenesis of pruritus. IL-31, whose production is induced by IL-4 and IL-33, binds a heterodi-meric receptor (R) composed of the exclusive IL-31RA chain and the shared oncostatin M R. Signaling through the IL-31R involves the MAPK, PI3K/AKT and Jak/STAT pathways. Different variants and isoforms of IL-31RA with different signaling activities have been identified. IL-31 is produced predominantly by circulating Th2 lymphocytes and skin-homing CLA+CD45RO+ T cells. Studies in humans have demonstrated a pathogenic role for IL-31 in atopic dermatitis and allergic asthma. The first demonstration of the involvement of the IL-31/IL-31R axis in cancer came from studies in patients with mycosis fungoides/Sézary syndrome, the most frequent, cutaneous T cell lymphoma. Tumor cells were shown to produce IL-31, whose serum levels correlated with pruritus intensity. Follicular lymphoma (FL) B cells and their counterparts—germinal center B cells—produced IL-31 and expressed IL-31R, which signaled in the former, but not the latter, cells. IL-31 released in association with microvesicles promoted tumor growth through autocrine/paracrine loops. Malignant mast cells from patients with mastocytosis or Philadelphia-negative myeloproliferative disorder produced IL-31, which contributed to pruritus pathogenesis. Finally, patients with endometrial carcinoma displayed high serum levels of IL-31 and IL-33, which may represent promising disease biomarkers. Targeting strategies for the IL-31/IL-31R axis have been developed, including the CIMM331 humanized anti-human IL-31RA antibody recently tested in a phase I/Ib study.
