Limb injuries such as severe strains, deep cuts, gunshot wounds, and ischemia can cause peripheral nerve damage. This can result in a range of clinical symptoms including sensory deficits, limb paralysis and atrophy, neuralgia, and sweating abnormalities in the innervated areas affected by the damaged nerves. These symptoms can have a significant impact on patients’ daily lives and work. Despite existing clinical treatments, some patients cannot achieve satisfactory therapeutic effects and continue to experience persistent paralysis and pain. Schwann cells are responsible for repairing and regenerating damaged nerves in the peripheral nervous system. They play a crucial role in the healing of nerve injuries and are essential for the restoration of proper nerve function. An increasing number of studies have focused on the various regulatory mechanisms that specifically affect the repair of damage by Schwann cells. This article aims to provide information on the different types of peripheral nerve injuries and their available treatments. We also discuss the various molecular mechanisms that regulate Schwann cell function during peripheral nerve repair and how they can be used to promote nerve repair and regeneration. Furthermore, we explore the potential therapeutic applications of precision regulation of Schwann cells for the treatment of peripheral nerve injuries.
