Splet14. okt. 2009 · The role of macrophage arginase in inflammation is also clearly demonstrated by the fact that the murine enzyme is inducible by pathogen-derived macromolecules like lipopolysaccharide (LPS) or lipoproteins (Corraliza et al., 1995), by a broad range of inflammatory stimuli (Hrabak et al., 2006) and in rat alveolar … Spletand TLR4 stimulation (Table 3). This was further confirmed by direct comparison of IL-10 responses to TLR3 and TLR4 ligands. Levels of secreted IL-10 in response to either receptor stimulation were comparable, and samples with robust responses to stimulation via one receptor also had good responses to the second receptor (Figure 1; P<.0001 and ...
