| Outline of Final Research Achievements |
Autoinflammation syndromes are caused by an exaggerated innate immune system response without autoatibodies and selfreactive T cells, and the patients show spontaneous inflammation affecting multiple organs. The Ali14 and Ali18 are gain-of-function mutations in cell signaling effector enzyme genes, and trigger inflammation through the innate immune cells by unknown mechanisms. Because the double mutant with Ali18 and W/Wv , which lacks mast cell population, did not show autoinflammation, we analyzed cultured mast cells from mutant bone marrow.Ali14 and Ali18 mast cells showed lower calcium concentration for antigen stimulation. Further, micro-array analysis identified 1124 and 750 up-regulated genes specifically in Ali18 and Ali14 mast cells, respectively. Further, 127 genes were up-regulated in both mutant mast cells. Cell signaling pathways involving these up-regulated genes might provide insight into extensive repression against autoinflammation.
