Decreased numbers of CD10−
polymorphonuclear leukocytes (PMN) from patients with systemic lupus erythematosus (SLE). The frequencies of CD10+CD16+ (mainly segment nucleated neutrophils) and CD10−CD16low (suggested as a marker for newly released neutrophils) PMN were investigated in healthy blood donors (HBD, n = 27) and patients (n = 73) using flow cytometry. The two-sided Mann-Whitney test was used to calculate the level of significance. The line represents the median value of each dataset.
