Galectin-10 (Gal-10) is a lectin family member and is one of the prototype galectins. It contains one carbohydrate recognition domain (CRD), responsible for beta-galactoside binding, and is biologically active as homodimers. It has been reported that galectin-10 is presented in eosinophils but also detected in basophils and macrophages. Accumulated evidence indicates that galectin-10 spontaneously forms Charcot-Leyden crystals (CLCs), participating in allergic responses and related inflammatory reactions. Several binding partners for galectin-10 have been identified, including eosinophil granule cationic ribonucleases, eosinophil-derived neurotoxin (EDN, RNS2), and eosinophil cationic protein (ECP, RNS3), demonstrating the interaction is essential for eosinophil differentiation and granulogenesis.
