Cytokine-induced neutrophil chemoattractant 1 (CINC-1) [4], a cluster of differentiation 95 (CD95) [5], fractalkine [6], and T-cell immunoglobulin and mucin domain 1 (TIM-1) [7] are circulating proteins that have been extensively studied in relation to cardiovascular diseases such as coronary artery disease (CAD), cerebrovascular disease (CVD), and PAD. Here, FAS is linked to peripheral arterial disease.
