Netrin-3 Suppresses Diabetic Neuropathic Pain by Gating the Intra-epidermal Sprouting of Sensory Axons / 神经科学通报·英文版

Diabetic neuropathic pain (DNP) is the most common disabling complication of diabetes. Emerging evidence has linked the pathogenesis of DNP to the aberrant sprouting of sensory axons into the epidermal area; however, the underlying molecular events remain poorly understood. Here we found that an axon guidance molecule, Netrin-3 (Ntn-3), was expressed in the sensory neurons of mouse dorsal root ganglia (DRGs), and downregulation of Ntn-3 expression was highly correlated with the severity of DNP in a diabetic mouse model. Genetic ablation of Ntn-3 increased the intra-epidermal sprouting of sensory axons and worsened the DNP in diabetic mice. In contrast, the elevation of Ntn-3 levels in DRGs significantly inhibited the intra-epidermal axon sprouting and alleviated DNP in diabetic mice. In conclusion, our studies identified Ntn-3 as an important regulator of DNP pathogenesis by gating the aberrant sprouting of sensory axons, indicating that Ntn-3 is a potential druggable target for DNP treatment.

Mucosal Immunity of IgA Nephropathy and Treatment from Pharynx / 中国中医药信息杂志

IgA nephropathy is a common primary glomerulopathy; the main clinical manifestation is hematuria, with or without proteinuria. However, the pathogenesis associated with mucosal immunity is not completely clear. At present, modern medical treatment delays the progression of IgA nephropathy mainly by controlling blood pressure, reducing proteinuria and delaying renal function failure. The method of combination of disease and syndrome of TCM has received satisfactory efficacy in the treatment of IgA nephropathy. Based on the relationship between mucosal immune and treated from pharynx, this article investigated the occurrence, development and treatment of IgA nephropathy.
