Galectin-1 deficiency attenuates imiquimod-induced psoriasiform skin inflammation and is associated with reduced macrophage recruitment

Introduction

Psoriasis is an immune-mediated inflammatory skin disease in which innate immune activation and the IL-23/IL-17 axis coordinate keratinocyte hyperproliferation and leukocyte recruitment. Galectin-1 (Gal-1) is a glycanbinding protein with context-dependent immunoregulatory effects; however, its function in psoriasiform skin inflammation remains incompletely defined.
