TNFα drives platelet hyperreactivity and thromboinflammation through regulation of hematopoietic stem and progenitor cells.
TNF is the primary age-related cytokine responsible for hyperreactive platelet formation. In mouse models, increased TNF induced abnormal megakaryocyte development and platelet activity. Here, we extend these findings to demonstrate that TNF drives this thrombotic phenotype through expansion of the hematopoietic stem and progenitor cell (HSPCs) compartment. Using HSPC-specific TNF receptor…
