ITGA2B and chronic kidney disease: 2012). We found an increase in platelet‐derived CD42b+MP over the course of HD, irrespective of whether exercise had taken place or not. However, we found no changes in phosphatidylserine+CD42b+MP. Platelet‐derived CD41 + MP (Daniel et al. 2006; Faure et al. 2006) and CD42 + MP (Burton et al. 2013) have been shown to be increased in number in both nondialysis CKD and HD patients compared to healthy controls, and differences may be again related to the use of phosphatidylserine expression to define MP (Erdbrügger and Li 2016).
