Dendritic cells
To form the IL-31 receptor, Interleukin 31 receptor A heterodimerizes with
Oncostatin-M specific receptor subunit beta
IL-31 drives
Itch - Nerve activation, thickening, elongation & branching
Inflammation - induces additional chemokines & cytokines
Barrier dysfunction - disrupts normal keratinocyte differentiation
Fibrosis - triggers tissue remodeling
