|Abstract:||Although S100A8/A9 (calprotectin) and S100A12 proteins expressed by neutrophils lack a signal peptide, they are found in the serum of patients with various inflammatory diseases. However, the mechanisms of secretion and the agonists that promote their secretion are still unknown. We hypothesized that several alternative secretory pathways and several agonists of neutrophils may participate in the release of S100A8/A9 and S100A12 protein. Initially, we studied the stimuli inducing the secretion of calprotectin and / or S100A12. In a second part, we were interested in signals and alternative mechanisms of secretion involved in the release of the calprotectin and S100A12. In conclusion, this study shows the complexity of alternative secretion pathways involved in S100 secretion and that these pathways are influenced by the activation of neutrophils by various agonists.|
