Conjunctival epithelial CD8+ lymphocytes do not display a proinflammatory or regulatory phenotype. Flow cytometry plots were gated on live CD45+CD56−CD8+CD45RO+ cells. Representative plots showing production of IL-17, -22, and -10 among conjunctival and matched peripheral blood (PB) cells (A–C). Comparative analyses are shown in (D–F). Statistical analysis was undertaken by the Wilcoxon matched-pairs signed rank test; NS, not significant, P > 0.05. OSIC, conjunctival ocular surface impression cytology.
