IL-31 plays a role in which clinical symptom commonly seen with dermatitis?

Explanation:
IL-31 is a cytokine produced by activated T cells that directly drives the itch sensation in inflammatory skin conditions like dermatitis. It signals to receptors on cutaneous sensory neurons, amplifying pruritus—the intense itch that is a hallmark symptom of dermatitis. This makes pruritus the most relevant clinical effect linked to IL-31, more so than effects on hair growth, appetite, or thermoregulation. Therapies that block IL-31 signaling have been shown to reduce itch in dermatitis, reinforcing the strong connection between IL-31 and pruritus.
