1 24343645 Janus kinase 3 activity is necessary for phosphorylation of cytosolic phospholipase A2 and prostaglandin E2 synthesis by macrophages infected with Francisella tularensis live vaccine strain.
2 24343645 The synthesis of PGE2 begins with the liberation of arachidonic acid (AA) from membrane phospholipids by cytosolic phospholipase A2 (cPLA2).
3 24343645 In this study, we show that cPLA2, p38 mitogen-activated protein kinase (MAPK), and Janus kinase 3 (JAK3) signaling are necessary for F. tularensis-induced PGE2 production.
4 24343645 Inhibition of JAK3 activity reduced the phosphorylation of cPLA2 and COX-2 protein levels.
5 24343645 In addition, JAK3 regulates cPLA2 phosphorylation independent of transcription.
6 24343645 Moreover, p38 MAPK activity is required for F. tularensis-induced COX-2 protein synthesis, but not for the phosphorylation of cPLA2.
7 24343645 This research highlights a unique signaling axis in which JAK3 and p38 MAPK regulate the activity of multiple enzymes of the PGE2-biosynthetic pathway in macrophages infected with F. tularensis.
8 24343645 Janus kinase 3 activity is necessary for phosphorylation of cytosolic phospholipase A2 and prostaglandin E2 synthesis by macrophages infected with Francisella tularensis live vaccine strain.
9 24343645 The synthesis of PGE2 begins with the liberation of arachidonic acid (AA) from membrane phospholipids by cytosolic phospholipase A2 (cPLA2).
10 24343645 In this study, we show that cPLA2, p38 mitogen-activated protein kinase (MAPK), and Janus kinase 3 (JAK3) signaling are necessary for F. tularensis-induced PGE2 production.
11 24343645 Inhibition of JAK3 activity reduced the phosphorylation of cPLA2 and COX-2 protein levels.
12 24343645 In addition, JAK3 regulates cPLA2 phosphorylation independent of transcription.
13 24343645 Moreover, p38 MAPK activity is required for F. tularensis-induced COX-2 protein synthesis, but not for the phosphorylation of cPLA2.
14 24343645 This research highlights a unique signaling axis in which JAK3 and p38 MAPK regulate the activity of multiple enzymes of the PGE2-biosynthetic pathway in macrophages infected with F. tularensis.
