巨噬細胞清除劑Clodronate Liposomes氯膦酸鹽脂質體廣泛用于體內和體外清除單核巨噬細胞,我們在使用荷蘭Liposoma巨噬細胞清除劑時,盡管該產品頻頻見刊于Cell,Nature和Science。但是巨噬細胞清除劑會不會清除中心粒細胞?很多研究者有這個擔心。一方面我們可以在自己的模型里面驗證,另一方面,我們也可以參考文獻。比如如下這篇JCI的老牌雜志文獻,炎性疼痛模型。作者的數據證明:巨噬細胞清除劑Clodronate Liposomes氯膦酸鹽脂質體(Liposoma)不會清除中心粒細胞。

Depletion of hindpaw skin macrophages (sMΦ) by systemic injection of clodronate-liposome.
(A) Flow cytometry images showing a reduction of F4/80+ CD11b+ sMΦ in inflamed hind paw skins after intraperitoneal
injections (15 µl/g, 2 and 48 h prior to the zymosan injection) of clodronate-liposome. Right panel, quantification of the
data.
(B) Flow cytometry showing no reduction of Gr1+ CD11b+ neutrophils in inflamed hind paw skins after
clodronate-liposome treatment. Right panel, quantification of the data. n = 3 mice /group, *P<0.05,
clodronate vs. control, #P<0.05, compared with contralateral, ns, not significant. All the data are mean ± SEM.
