Figure Lengend Snippet: Experimental groups

Article Snippet: C57BL/6 mice were randomly divided into five groups: (1) Control group, which underwent the surgical procedures but without TBI; (2) TBI group, which received saline for 3 days; (3) TBI + DEX group (Sigma–Aldrich, D4902), which was administered an intraperitoneal injection once per day for 3 days; (4) DEX+RU486 (Abcam, Cambridge, UK, Cat# ab120356), which received a GR antagonist, RU486, twice a day for 1 day before TBI and 3 days after surgery; administration of DEX was consistent with group (3); and (5) RU486 + ruxolitinib group (TargetMol, Wellesley Hills, MA, USA, Cat# 1,092,939-17-7), which received RU486 as in group (4) , while the Janus kinase (JAK) inhibitor, ruxolitinib, was administered twice daily for three days post-TBI (Lescoat et al., 2020; Chen et al., 2021).

Figure Lengend Snippet: RU486 and ruxolitinib treatment decreases DEX-induced apoptosis following TBI. (A, B) Representative photomicrographs (A) and quantification (B) of terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) staining. Apoptotic cells were measured in the ipsilateral hippocampus and cortex surrounding the injury site. Green represents TUNEL-positive cells. Blue represents DAPI. Scale bars: 20 μm. Data are expressed as mean ± SD, n = 3. * P < 0.05, vs . Control; # P < 0.05, vs. traumatic brain injury (TBI) (one-way analysis of variance with the least significant difference test). DAPI: 4′,6-Diamidino-2-phenylindole; DEX: dexamethasone; TBI: traumatic brain injury.

Figure Lengend Snippet: Inhibition of GR attenuates neuronal death. (A) Representative image of Nissl staining in the peri-injured cortex and hippocampus. (B) Quantification analysis showed that DEX induced a significant decrease in Nissl-positive cells post-TBI. RU486 application alleviated neuronal loss. Scale bars: 20 μm. Data are expressed as mean ± SD, n = 3. * P < 0.05, vs . Control; # P < 0.05, vs. TBI (one-way analysis of variance with the least significant difference test).
