Abstract
Aims: This study aims to explore the potential role of vascular endothelial growth factor-B (VEGF-B) in the pathogenesis of diabetic peripheral neuropathy (DPN). The expression of VEGFRs were reanalysed by using gene arrays of peripheral nerve samples from mouse models of DPN retrieved from the GEO database. 213 T2D patients as well as 31 healthy individuals were recruited. The serum VEGF-B was detected and its relationship with DPN was analysed. The elevated VEGFR1 was the only change of VEGFR gene expression in the peripheral nerve from mouse models of DPN. The level of serum VEGF-B in T2D patients with DPN was higher than that in T2D patients without DPN and healthy people. Analysis of correlation and binary logistic regression confirmed that the increased serum VEGF-B level was an independent risk factor of DPN in T2D patients. VEGF-B-VEGFR1 signaling pathway may be involved in the development of DPN.
