Kallistatin, a multifunctional serine protease inhibitor, is widely distributed with tissue-specific effects. It may serve as a new diagnostic biomarker and therapeutic target for human diseases. Through binding to its two structural elements and specific receptors, it regulates differential signaling cascades, and thus has a wide spectrum of biological functions. In cardiovascular diseases like hypertension, atherosclerosis, and heart failure, it exerts protective effects by improving endothelial function, anti-inflammation, and regulating lipid metabolism. In liver diseases, high hepatic expression correlates with nonalcoholic fatty liver disease, while decreased serum levels indicate severe cirrhosis or liver fibrosis. In metabolic diseases, it regulates insulin resistance, glucose metabolism, angiogenesis and inflammation. In inflammatory diseases, its role is dual: it attenuates inflammation in rheumatoid arthritis, sepsis, etc., but exacerbates chronic rhinosinusitis and autoimmune uveitis by promoting inflammatory cytokines secretion. In cancer, it inhibits tumor cell proliferation, angiogenesis, and metastasis, with lower tumor tissue expression linked to cancer development. Kallistatin also serves as a potential biomarker for chronic kidney disease, preterm birth, neurodegenerative diseases, and other diseases. This review synthesizes current knowledge on kallistatin's mechanisms in organ injury and repair, emphasizes its therapeutic potential across disease contexts, and discusses challenges and future directions for clinical translation, including organ-targeted strategies and combination therapies.
