PG - 145-153 LID - S1567-5769(18)30122-X [pii] LID - 10.1016/j.intimp.2018.03.019 [doi] AB - Accumulating evidence has shown that macrophages play a vital role in development and pathogenesis of diabetic nephropathy (DN) by secreting inflammatory cytokines. Although Bruton's tyrosine kinases (Btk) is a biologically important molecule implicated in immune regulation, the role of Btk in high glucose (HG)-stimulated inflammatory response in macrophages and the mechanism involved need further investigation. In our study, we used bone marrow-derived macrophages (BMMs) to investigate the involvement of Btk on HG-induced inflammatory cytokines expression and to explore the underlying mechanisms. We found that high glucose induced phosphorylation of Btk, MAPKs and NF-kappaB, and the expression of downstream inflammation cytokines monocyte chemo-attractant protein-1 (MCP-1), tumor necrosis factor-alpha (TNF-alpha) and interleukin-1beta (IL-1beta). Btk inhibitor (PCI-32765) not only down-regulated ERK1/2 phosphorylation and NF-kappaB activation, but also decreased the secretion of MCP-1, TNF-alpha and IL-1beta in HG-treated BMMs. These results indicate that Btk plays an important role in HG-induced inflammatory cytokines expression and that PCI-32765 may be used as an immunoregulatory agent against hyperglycemia-induced inflammatory response in DN.
