Meanwhile, AAA has a tight relationship with vascular remolding, in which MMPs play a pivotal role, and MMP-2 and MMP-9 are considered to be crucial to extracellular matrix (ECM) degradation (Figure 1); furthermore, MMPs may facilitate inflammation [12] and vice versa, inflammation contributions to extracellular matrix remodeling [13]. This evidence concerns the gene MMP2 and triple-A syndrome.
