Article Title: Exploring the role of PD-1 as a marker in drug-refractory epilepsy and its potential indication for valproic acid treatment

doi: 10.1016/j.bbih.2026.101238

Figure Lengend Snippet: Elevated PD-1 expression and altered cytokine levels in plasma of IE patients. (A) PD-1 expression on CD4 + CD25 high Tregs is significantly increased in IE patients, particularly in the ISE subgroup, while CD4 + and CD4 + CD25 + T cell percentages are reduced. (B) Plasma concentrations of IL-10 and IL-6 are elevated in IE patients, with IL-10 showing a progressive increase with seizure severity. (C) Correlation analyses reveal associations between immune parameters and clinical characteristics. ∗∗∗P < 0.001, ∗∗ P < 0.01, ∗ P < 0.05; ns indicates not significant.

Figure Lengend Snippet: VPA treatment modulates PD-1 expression and IL-10 levels independently of drug concentration. (A) Plasma PD-1 expression on both CD4 + CD25 high and CD4 + CD25 low Treg subsets decreases significantly after 48 h of VPA treatment. (B) Plasma IL-10 levels decrease significantly after VPA treatment, while IL-6 shows no significant change. (C) Seizure control time correlates with immunological parameters but not with VPA concentrations. (D) VPA concentrations in CSF are significantly lower than in plasma, with no change between d0 and d3, and no correlation with seizure control time. ∗∗∗P < 0.001, ∗∗P < 0.01, ∗P < 0.05; ns indicates not significant.
