Isabelle Allaeys, Guillaume Lemaire, Mickaël Leclercq, et. al. Blood Adv (2024) 8 (11): 2777–2789. Megakaryocytes (MKs), integral to platelet production, predominantly reside in the bone marrow (BM) and undergo regulated fragmentation within sinusoid vessels to release platelets into the bloodstream. Inflammatory states and infections influence MK transcription, potentially affecting platelet functionality. Notably, COVID-19 has been associated […]
