Figure Lengend Snippet: Reduced tyrosine hydroxylase (TH) expression in the hippocampus of htauE14 rats and increased Brain‐Derived Neurotropic Factor (BDNF) expression following early enrichment. (A) Relative optical density (ROD) of TH expression across different groups. N = 4F/4M (cGFP), 6F/4M (cE14), 4F/2M (eSTR.E14), 3F/3M (eER.E14), 5F/3M (lSTR.E14), and 5F/1M (lER.E14). (B) ROD of BDNF expression, showing increased levels with early enrichment. N = 5F/5M (cGFP), 6F/6M (cE14), 6F/2M (eSTR.E14), 4F/4M (eER.E14), 6F/4M (lSTR.E14), and 6F/2M (lER.E14). (C) ROD of glucocorticoid receptor (GR) expression across groups. N = 5F/5M (cGFP), 6F/6M (cE14), 6F/2M (eSTR.E14), 4F/4M (eER.E14), 6F/4M (lSTR.E14), and 6F/2M (lER.E14). (D) ROD of Triggering Receptor Expressed on Myeloid cells 2 (TREM2) expression across groups. N = 5F/5M (cGFP), 6F/6M (cE14), 6F/2M (eSTR.E14), 4F/3M (eER.E14), 6F/4M (lSTR.E14), and 5F/2M (lER.E14). (E) ROD of tumor necrosis factor α (TNFα) expression across groups. N = 4F/5M (cGFP), 6F/5M (cE14), 5F/2M (eSTR.E14), 3F/4M (eER.E14), 6F/3M (lSTR.E14), and 5F/2M (lER.E14). * p < 0.05; ** p < 0.01.
