CD4⁺/CCR5⁺ T cell percentage in the conjunctiva. (A) Representative images of CD4⁺/CCR5⁺ T cells and (B) mean percentage of CD4⁺/CCR5⁺ T cells in the UT, EDE, BSS, 0.05% CsA and 0.1% Gly-Tβ4 groups after 14 days. The Gly-Tβ4- and CsA-treated groups had a significantly lower percentage of CD4⁺/CCR5⁺ T cells in the conjunctiva compared with the EDE and BSS groups. There were no notable differences between the two treatment groups. ^*P<0.05 vs. EDE group; ^†P<0.05 vs. BSS group. UT, untreated control; EDE, experimental dry eye; BSS, balanced salt solution; CsA, Cyclosporine A; Gly-Tβ4, glycine-thymosin β4.
