TSPAN12 and eosinophilic esophagitis: TSPAN12 expression was significantly lower in fibrostenotic vs. nonfibrostenotic EoE and, in addition to correlating with endoscopic, histologic, and molecular features of EoE, TSPAN12 also correlated with fibrostenotic features (i.e., TSPAN12 correlated directly with esophageal diameter and inversely with lamina propria fibrosis and with ECM-related genes including collagens and MMPs).
