Bridging worlds: a narrative review of IL-17 at the crossroads of inflammation and thrombosis.

Interleukin-17 (IL-17) has emerged as a key cytokine at the intersection of inflammation and thrombosis, potentially playing a pivotal role in thromboinflammation. This review explores the mechanistic contributions of IL-17 to endothelial dysfunction, platelet activation, monocytes activation, and neutrophil extracellular trap (NET) formation, which collectively promotes a pro-thrombotic state. We summarize findings from experimental models and clinical studies linking IL-17 to thrombosis in autoimmune diseases, atherosclerosis, and infectious diseases such sepsis and COVID-19. Additionally, we discuss the therapeutic implications of IL-17 inhibition in mitigating thromboinflammatory complications. Understanding the role of IL-17 in this process may provide new avenues for targeted interventions in thromboinflammatory disorders.
