Decreased serum <scp>LL</scp>‐37 and vitamin <scp>D</scp>3 levels in atopic dermatitis: relationship between <scp>IL</scp>‐31 and oncostatin <scp>M</scp>

Abstract

Systemic vitamin D3 levels are reduced in patients with AD, which may contribute to decreased systemic LL-37 levels. LL-37 may systemically potentiate the oncostatin M and IL-31 production in normal donors and patients with AD, while vitamin D3 may do so only in normal donors.
