LCN2 and metabolic dysfunction-associated steatotic liver disease: Moreover, confocal immunofluorescence images revealed a partial colocalization of LCN2 with neutrophil marker Ly6G or with macrophage marker F4/80, demonstrating both neutrophils and macrophages as the major cell populations contributing to Tim-1-enhanced LCN2 upregulation in diet-induced NAFLD/NASH mouse model.
