Suppressive effect of ImK on T‐cell infiltration and inflammatory cytokine production in the CNS of the Experimental autoimmune encephalomyelitis group. CD3+ cell infiltration (A) was displayed in the white matter of lumbar spinal cord (n = 8, *P < 0.05). Double‐fluorescent immunostaining demonstrated CD3+Kv1.3+ cells (arrowheads) (B,C) infiltration in lesions (n = 6, *P < 0.05). The concentrations of IL‐2 (D) and IFN‐γ (E) in CSF were measured using ELISA (n = 6, *P < 0.05, ***P < 0.001)
