Objectives:
We aimed to evaluate the neuroprotective effect of Indole-3-propionic acid (IPA) against streptozotocin (STZ) induced diabetic peripheral neuropathy (DPN) in rats and in high glucose (HG) induced neurotoxicity in neuro2a (N2A) cells.
Methods:
Diabetes was induced in male SD rats STZ (55 mg/kg, i.p.) and IPA (10 and 20 mg/kg, p.o.) was administered for two weeks, starting from sixth week after diabetes induction. Neurobehavioral, functional assessments were made, and various molecular studies were performed to evaluate the effect of IPA on HG induced ER stress and mitochondrial dysfunction in sciatic nerves, DRGs and in N2A cells.
Results:
Diabetic rats and high glucose exposed N2A cells showed marked increase in oxidative damage accompanied by ER stress and mitochondrial dysfunction along with increased apoptotic markers. IPA treatment for two weeks markedly alleviated these changes and attenuated pain behaviour.
Conclusion:
IPA exhibited neuroprotective activity against hyperglycaemic insults.

Pathophysiology of Diabetes
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...
