作者表明,氯膦酸盐脂质体的抗炎作用不是由于单核吞噬细胞的消耗,而是由于多形核中性粒细胞的功能性休克。这些发现需要对当前关于单核细胞和巨噬细胞在炎症中的作用的文献进行批判性修订。氯膦酸盐脂质体(Clo-Lip)已被广泛用于消耗单核吞噬细胞(MoPh)以研究这些细胞在体内的功能。在这里,我们重新审视了Clo-Lip的作用以及MoPh缺乏的遗传模型,揭示了Clo-Lip独立于MoPh发挥其抗炎作用。值得注意的是,不仅MoPh,而且多形性嗜中性粒细胞(PMN)在体内摄入Clo-Lip,这导致其功能停滞。PMN的连续转移,而不是MoPh的连续转移,逆转了Clo-Lip治疗的抗炎作用,表明PMN的抑制而不是MoPh的消耗是Clo-Lip体内抗炎作用的原因。我们的数据强调需要对当前关于MoPh在炎症中的作用的文献进行重要修订。
The authors show that the anti-inflammatory effects of clodronate liposomes do not result from the depletion of mononuclear phagocytes but from a functional stunning of polymorphonuclear neutrophils. These findings necessitate a critical revision of the current literature on the role of monocytes and macrophages in inflammation. Clodronate liposomes (Clo-Lip) have been widely used to deplete mononuclear phagocytes (MoPh) to study the function of these cells in vivo. Here, we revisited the effects of Clo-Lip together with genetic models of MoPh deficiency, revealing that Clo-Lip exert their anti-inflammatory effects independent of MoPh. Notably, not only MoPh but also polymorphonuclear neutrophils (PMN) ingested Clo-Lip in vivo, which resulted in their functional arrest. Adoptive transfer of PMN, but not of MoPh, reversed the anti-inflammatory effects of Clo-Lip treatment, indicating that stunning of PMN rather than depletion of MoPh accounts for the anti-inflammatory effects of Clo-Lip in vivo. Our data highlight the need for a critical revision of the current literature on the role of MoPh in inflammation.
