CD24 and Sepsis: Pillay et al. showed that CD16dimCD62Lbright band cells could not affect T cell proliferation (35), but Guerin et al. reported that CD14–CD24+ immature neutrophils (possibly band cells) isolated from LDNs of sepsis patients showed cytotoxicity to lymphocytes (36), while Singhal et al. recently reported that the CD66b+CD10– band cells derived from bone marrow might produce promoting proliferation of lymphocytes (40).
