Taurine protects against myelin damage of sciatic nerve in diabetic peripheral neuropathy rats by controlling apoptosis of schwann cells via NGF/Akt/GSK3 β pathway.

In this study, we explore the effect of taurine on preventing SCs apoptosis and its underlying mechanism. Sprague Dawley rats were treated with streptozotocin to establish the diabetes model. Rats were randomly divided into control, diabetes, taurine treatment (as giving 0.5%, 1% and 2% taurine in drinking water) groups. RSC96 cell (a rat SCs line) was used for intervention experiments in vitro. Results showed that taurine significantly corrected morphology of damaged myelin sheath and inhibited SCs apoptosis in sciatic nerve of diabetic rats. Moreover, taurine prevented apoptosis of RSC96 cells exposed to high glucose. Mechanistically, taurine up-regulated NGF expression and phosphorylation levels of Akt and GSK3β, while, blocking activation of NGF and phosphorylation of Akt and GSK3β increased apoptosis of high glucose-exposed RSC96 cells with taurine supplement. These results revealed taurine improved the myelin sheath damage of sciatic nerve in diabetic rats by controlling SCs apoptosis via NGF/Akt/GSK3β signaling pathways, which provides some clues that taurine might be effective and feasible candidate for the treatment of DPN.

Abstract OBJECTIVE: To explore the changes that occur in the concentrations of substance P (SP) and calcitonin gene-related peptide (CGRP) in tears as a result of corneal denervation and its association with diabetic peripheral neuropathy (DPN). METHODS: Sixty-three individuals with type 1 diabetes/type 2 diabetes (T1D/T2D) and 34 age-matched healthy controls underwent a detailed assessment of neuropathy using the Total Neuropathy Score (TNS). The concentration of SP and CGRP in tears was measured by enzyme-linked immunosorbent assay. The corneal sub-basal nerve plexus was imaged using corneal confocal micros...

AbstractPurpose of ReviewDiabetic peripheral neuropathy eventually affects nearly 50% of adults with diabetes during their lifetime and is associated with substantial morbidity including pain, foot ulcers, and lower limb amputation. This review summarizes the epidemiology, risk factors, and management of diabetic peripheral neuropathy and related lower extremity complications.Recent FindingsThe prevalence of peripheral neuropathy is estimated to be between 6 and 51% among adults with diabetes depending on age, duration of diabetes, glucose control, and type 1 versus type 2 diabetes. The clinical manifestations are variable...

This study aimed to determine whether there were significant differences in these complications in patients with T2DM with and without hypothyroidism. METHODS: This was a retrospective, cross-sectional, case-control study from a single centre specialising in diabetes in South Africa. T2DM was defined by American Diabetes Association criteria. The cases were all patients treated for hypothyroidism and the controls were clinically and biochemically confirmed euthyroid, who were under follow up between 1 January and 1 July 2016. Chronic kidney disease (CKD) was defined as an estimated glomerular filtration rate (eGFR) of...

AbstractIntroductionComplications from diabetes mellitus (DM) include cardiovascular system, peripheral neuropathy (PN), and autonomic dysfunction (AD). Goal: Assess the association of silent myocardial ischemia, AD, and PN in cardiovascular asymptomatic type 2 diabetics.MethodsAs part of a multicenter project, 40 patients with type 2 DM were studied, with> 5 years of known disease and a baseline electrocardiogram non suggestive of coronary artery disease. Myocardial SPECT was performed with exercise stress test measuring corrected QT interval (QTc) and heart rate recovery (HRR) post-exercise (abnormal QTc ≥ 450 ms at rest and HRR

Conclusion: More than half of the patients included in this study were found to have neuropathy, nearly half of whom presented with the severe form. The main risk factors were increasing age, increasing duration of diabetes, obesity, and hypertension. Diabetic peripheral neuropathy is underdiagnosed in northern Tanzania where screening for neuropathy is not routinely done. PMID: 31275374 [PubMed]
