Abstract

Macrophages play a key role in tissue regeneration following peripheral nerve injury by preparing the surrounding parenchyma for regeneration, however, they can be damaging if the response is excessive. Interleukin 10 (IL-10) is a cytokine that promotes macrophages toward an anti-inflammatory/wound healing state (M2 phenotype). The bioactive half-life of IL-10 is dependent on the cellular microenvironment and ranges from minutes to hours in vivo. Our objective was to extend the in vivo bioavailability and bioactivity of IL-10 by attaching the protein onto nanofibrous scaffolds and demonstrating increased expression levels of M2 macrophages when placed around healthy intact peripheral nerves...
