CCL2 and acute respiratory distress syndrome: ARDS has been shown to be mainly the consequence of an exacerbated immune response that leads to a massive release of a specific subset of proinflammatory cytokines, such as TNF-α, IL-2, IL-6, IL-7, IL-10, granulocyte-colony-stimulating factor (G-CSF), interferon-γ-induced protein 10 (IP10), monocyte chemoattractant protein-1 (MCP-1), macrophage inflammatory protein 1 α (MIP-1A) and C-reactive protein (CRP) [78,79,80].
