metabolism | human umbilical vein endothelial cells, activated by recombinnat MASP-1, secrete interleukin-6 and interleukin-8, but not interleukin-1alpha, interleukin-1ra, TNFalpha and MCP-1. rMASP-1 induces interleukin-6 and interleukin-8 production with different kinetics. Enzyme-triggered interleukin-6 and interleukin-8 production is regulated predominantly by the p38-MAPK pathway. The supernatant of rMASP-1-stimulated cells activates the chemotaxis of neutrophil granulocytes as an integrated effect of cytokine production | Homo sapiens |
physiological function | MASP-1, the most abundant enzyme of the complement lectin pathway, can induce p38-MAPK activation, NFkappaB signaling, and Ca2+-mobilization in endothelial cells and induces a unique cytokine pattern in endothelial cells linking complement system and neutrophil granulocytes. Besides initializing the complement lectin pathway, MASP-1 may activate neutrophils indirectly, via the endothelial cells, which link these effective antimicrobial host defense mechanisms | Homo sapiens |
