Role of PPARγin the Differentiation and Function of Neurons

Abstract

Neuronal processes (neurites and axons) have an important role in brain cells communication and, generally, they are damaged in neurodegenerative diseases. Recent evidence has showed that the activation of PPARγpathway promoted neuronal differentiation and axon polarity. In addition, activation of PPARγusing thiazolidinediones (TZDs) prevented neurodegeneration by reducing neuronal death, improving mitochondrial function, and decreasing neuroinflammation in neuropathic pain. In this review, we will discuss important evidence that supports a possible role of PPARγin neuronal development, improvement of neuronal health, and pain signaling. Therefore, activation of PPARγis a potential target with therapeutic applications against neurodegenerative disorders, brain injury, and pain regulation.
