MYH9相关综合征患者血小板和中性粒细胞的超微结构及其病理特点
Ultrastructure and pathologic features of platelet and neutrophil in patients with MYH9-RD
摘要
Abstract
Objective:To study the ultrastructure and pathologic features of platelet and neutrophil in patients from a family (GXMS family) with non-muscle myosin heavy chain 9 related disease (MYH9-RD).Methods:Morphological characteristics of neutrophils,platelets and their organelles in peripheral blood of patients were observed by optical microscope and transmission electron microscope.Results:The proband in the GXMS family presented with giant platelet,thrombocytopenias and neutrophil inclusions.The platelets of all patients were heterogeneous in organelles content,and had increasing number of dense and α-granules,as well as open-canalicular systems,which were proportional to the increased platelet volume.The mitochondrial swelled significantly in 85% of the platelets,the open-tubular increased obviously in 62% of the platelets,and the pseudopodia were observed in 90% of the platelets.Some regions in giant platelets were surrounded by microtubules and endoplasmic reticulum,which were similar to the neutrophil inclusions in shape.Conclusion:Abnormal NMMHC-ⅡA resulted in a inhomogeneous organelle distribution within platelets,and it is likely to be an essential factor for maintaining the activation state of the platelets in patients with MYH9-RD.关键词
