Fig 1: Effects of BCG and scopolamine on the gene expressions of A RORγt, B STAT3, and the protein content of C IL-17 and D IL-22 in the rat’s cerebral cortex. Results are presented as mean ± SE. Statistical investigations were done by the ANOVA test and then Tukey’s post hoc test. IL, interleukin; RORγt, retinoic acid-related orphan receptor; STAT, signal transducer and activator of transcription
