Mer activation alleviated functional deficits following TBI. a–c Representative immunoblots and quantification showing protein expression of p-STAT1 (a), SOCS-1 (b), and SOCS-3 (c) in the injured cortex at 3 days post-TBI; TBI + vehicle: TBI + V, TBI + recombinant protein S: TBI + PS. GAPDH: loading control. Data are expressed as fold change compared to the sham group; n = 6 mice per group. d–i Quantitative RT-PCR analysis of MACS-sorted CD11b-positive cells showing mRNA expression of CD16 (d), CD32 (e), iNOS (f), CD206 (g), Arg-1 (h), and IL-10 (i) in the injured cortex at 3 days post-TBI. GAPDH: loading control. Data are expressed as fold change compared to the sham group; n = 6 mice per group. j–l Modified neurological severity scores (mNSS) (j), foot-fault test (k), and rotarod test (l) were performed at 3 days after TBI. n = 8 mice per group. In a–l, data are presented as mean ± SD; ***, p < 0.001. One-way ANOVA followed by Bonferroni’s post hoc tests
