Xie et al. [24] compared the proteomic patterns of plasma exosomal proteins between patients with EBV-HLH and healthy controls, yielding several potential biomarkers for EBV-HLH: CRP, moesin (MSN), galectin-3-binding protein (LGALS3BP), heat shock cognate 71 kDa protein (HSPA8), plasminogen (PLG), and fibronectin 1. The gene discussed is LGALS3BP; the disease is hemophagocytic syndrome.
