Exposure of human monocytes-macrophages to anti-inflammatory agents, such as IL-10 or glucocorticoids, can lead to two separate fates: either Fas/CD95-mediated apoptosis or differentiation into regulatory and efferocytic M2c (CD14brightCD16+CD163+MerTK+) macrophages. We found that the prevalent effect depends on the type of T-helper cytokine environment and on the stage of monocyte-to-macrophage differentiation. In particular, the presence of IFNγ (Th1 inflammation) or the prolonged exposure to IL-4 (chronic Th2 inflammation) promotes apoptosis of monocytes-macrophages and causes resistance to M2c differentiation, so provoking impaired clearance of apoptotic neutrophils, uncontrolled accumulation of apoptotic cells and persistent inflammation. By contrast, the presence of IL-17 (Th17 environment) prevents monocyte-macrophage apoptosis and elicits intense M2c differentiation, so ensuring efficient clearance of apoptotic neutrophils and restoration of anti-inflammatory conditions. Additionally, the T helper environment affects the expression of two distinct MerTK isoforms: IL-4 down-regulates the membrane isoform but induces an intracellular and Gas6-dependent isoform, whereas IFNγ down-regulates both and IL-17 upregulates both. Our data support an unexpected role for IL-17 in orchestrating resolution of innate inflammation, whereas IFNγ and IL-4 emerge as major determinants of IL-10 and glucocorticoid resistance.
