Moreover, L. acidophilus LA14 was found to reduce d-galactosamine (D-GalN)-induced ALI by lowering the concentrations of macrophage inflammatory protein 1a (MIP-1a), MIP-3a, and monocyte chemoattractant protein-1 (MCP-1), suggesting reductions in macrophage activity (Lv et al., 2021). The gene discussed is CCL20; the disease is acute respiratory distress syndrome.
