Figure 1: T-cell surface markers in normal ocular surface.

(A) Cell surface markers for naïve, TCM, TEM and TEMRA subsets used in our studies. (B) Flow cytometry showing proportion of naïve, TCM, TEM and TEMRA subsets within CD4+ and CD8+ pools (left and right panels) in the nomal human conjunctiva. (C) Proportion of conjunctival naïve, TCM, TEM and TEMRA subsets in CD4+ and CD8+ T cell pools expressed as a percentage of the total number of CD3+ T cells in healthy human conjunctiva. Each data point represents a separate individual; mean ± SEM shown.
