These results have demonstrated that first, once again, caspase 4 SGs at the days 7 and 28 but not day 14 AAA aortas have two-peak signaling processes in the pathogenesis of AAA; second, the caspase 4 SGs in the day 14 AAA aortas have only one functional pathway; and third, the caspase 4 SGs in the day 7 and day 28 AAA aortas share two functional pathways, namely, Fcγ receptor-mediated phagocytosis in macrophages and monocytes and phagosome formation. The gene discussed is CASP4; the disease is triple-A syndrome.
