Exogenous treatment of IL-17A does not alter IL-17RA expression in glial culture. mRNA was isolated from either non-treated resting culture or IL-17A (10 ng/ml) treated culture supernatants at 12 hr in vitro. IL-17RA gene expression was measured by RT-PCR using a primer set from exon boundary 1–2. Data represent the mean expression from three different non- treated and IL-17A- treated culture batches ± SEM. IL-17A treatment did not alter IL-17RA expression in neonatal glial cells (*p > 0.05).
