Furthermore, as a result of treatment with liposomal clodronate, depletion of peripheral macrophages partially ameliorated the peripheral inflammation-evoked cognitive dysfunction. Taken together, these findings demonstrate that inhibition of peripheral HDAC plays a critical role in preventing cognitive dysfunction induced by peripheral inflammation via the regulation of anti-inflammatory cytokine production and the inhibition of microglial functions in the hippocampus. Thus, these findings could provide support for inhibition of peripheral HDAC as a novel therapeutic strategy for inflammation-induced cognitive dysfunction.Diabetic neuropathy is one of the common complications of type 2 diabetes mellitus (T2DM) with severe outcomes. The mechanisms of physiopathology of diabetic neuropathy are not well elucidated. Inflammation and inflammatory macrophages are recognized to be crucial in diabetic neuropathy. Toll-like receptor 2 (TLR2) is an important factor in innate immune response which could promote the polarization of inflammatory macrophages. In present study, we evaluated the effects of a TLR2 antagonist CU-CPT22 on diabetic neuropathy. We induced T2DM in mice by feeding with high fat diet (HFD). We measured the body weight, blood glucose level, paw withdrawal threshold, inflammatory cytokine production, and macrophages infiltration in T2DM mice. We evaluated the effects of CU-CPT22 on pro-inflammatory cytokines production, macrophage marker expression in lipopolysaccharides (LPS)-treated BMDMs. We administrated CU-CPT22 in T2DM mice and measured the pro-inflammatory cytokines levels, expression of macrophages markers in sciatic nerve (SCN), and paw withdrawal threshold. T2DM mice had significantly increased body weight and blood glucose, and had significantly decreased paw withdrawal threshold. Obvious increased pro-inflamm
