WebSchwann cells play an important role in peripheral nerve function, and their dysfunction has been implicated in the pathogenesis of diabetic neuropathy and other demyelinating diseases. The physiological functions of insulin in Schwann cells remain unclear and therefore define the aim of this study. Web27 Oct 2024 · Schwann cell dedifferentiation not only directly determines the process of demyelination but also plays a vital role in the clearance of the debris of axons and myelin, since the dedifferentiated Schwann cells can engulf the debris by themselves and secrete cytokines to recruit macrophages to enhance the debris clearance [ 9 ].
