For neutrophils, the elevated CD64 expression together with lowered neutrophil CD14 levels observed in the study group of severe COVID‐19 patients may indicate the presence of less mature proneutrophil‐like CD64+ CD14low cells expanding in early COVID‐19 [11] and sepsis [46, 47], and hence, represent a general reaction to a strong inflammatory stimuli triggering emergency myelopoiesis [11, 17]. Here, CD14 is linked to COVID-19.
