Single cell RNA sequencing of peripheral blood HSPC from patients with sickle cell anemia and healthy donors

Neutrophils and monocytes are critical contributors to the pathophysiology of sickle cell anemia (SCA) and are persistently elevated in patients' circulation. While chronic hemolysis has been implicated in this leukocytosis, the underlying mechanisms remain incompletely understood. Our data show a myeloid-skewed transcriptional signature in early progenitor populations, including multipotent progenitors (MPPs) and hematopoietic stem cells (HSCs). Notably, we identify upregulation of the type I interferon signaling pathway in HSPCs as a key driver of early myeloid programming in SCA.
