活化的巨噬细胞在先天性和适应性免疫应答中起重要作用,并且巨噬细胞的异常活化常常导致炎性和免疫病症。然而,巨噬细胞如何被激活的分子机制尚未完全了解。在这项研究中,我们确定了一个新的作用,组蛋白去乙酰化酶6(HDAC 6)在脂多糖(LPS)诱导的巨噬细胞活化。我们的数据显示,HDAC 6活性的抑制显著抑制LPS诱导的巨噬细胞活化和促炎细胞因子的产生。进一步的研究表明,HDAC 6对巨噬细胞活化的调节不依赖于F-肌动蛋白聚合和丝状伪足形成;相反,它是由HDAC 6对细胞粘附和微管乙酰化的影响介导的。因此,这些数据表明HDAC 6是LPS诱导的巨噬细胞活化的重要调节剂,并且可能是用于管理炎性疾病的潜在靶标。
Activated macrophages play an important role in both innate and adaptive immune responses, and aberrant activation of macrophages often leads to inflammatory and immune disorders. However, the molecular mechanisms of how macrophages are activated are not fully understood. In this study, we identify a novel role for histone deacetylse 6 (HDAC6) in lipopolysaccharide (LPS)-induced macrophage activation. Our data show that suppression of HDAC6 activity significantly restrains LPS-induced activation of macrophages and production of pro-inflammatory cytokines. Further study reveals that the regulation of macrophage activation by HDAC6 is independent of F-actin polymerization and filopodium formation; instead, it is mediated by the effects of HDAC6 on cell adhesion and microtubule acetylation. These data thus suggest that HDAC6 is an important regulator of LPS-induced macrophage activation and might be a potential target for the management of inflammatory disorders.
