Many cytokines have been found to mediate IL‐17 cytokine responses, most of which use a common receptor subunit, IL‐17RA.[23] Gene expression studies have shown that the expression of a large number of genes associated with innate immune cell recruitment to infection or tissue injury sites is promoted by IL‐17RA signal transduction.[24] In view of this, the growth of Schwann cells on HASPy hydrogel increased the expression of the IL‐17 pathway; therefore, we selected IL‐17RA to verify the high expression of the IL‐17 pathway. Here, IL17RA is linked to infection.
