LCN2 and bacterial infectious disease: Similar to Vero, a number of cytokines associated with bacteria were identified in Huh7 cells, such as lipocalin 2 (LCN2), which inhibits bacterial infection, was upregulated, whereas C-C motif chemokine ligand 26 (CCL26), a chemoattractant for eosinophils and basophils, was downregulated.
