Activated platelets may interact with various types of leukocytes such as monocytes, neutrophils, dendritic cells, and lymphocytes, trigger intercellular signal transduction, and thus lead to thrombosis and synthesis of massive inflammatory mediators. Elevated levels of circulating platelet-leukocyte aggregates have been found in patients with thrombotic or inflammatory diseases. This article reviews the latest research on the formation, function, and detection methods of platelet-leukocyte aggregates and their role in the onset of Kawasaki disease, so as to provide new ideas for studying the pathogenesis of Kawasaki disease.
活化的血小板会与单核细胞、中性粒细胞、树突状细胞和淋巴细胞等各类白细胞相互作用，触发细胞间信号转导，从而导致血栓形成和炎症介质的大量合成。已在多种血栓性疾病和炎症性疾病中发现血液中血小板-白细胞聚集体水平升高，该文综述了最新文献，探讨血小板-白细胞聚集体形成机制、作用、检测方法及其在川崎病发病中的相关作用，为川崎病发病机制的研究提供了新思路。.
