CD8A and keratoconus: In contrast, GW significantly decreased levels of CD8+ T cells (Fig. 5h) and CD4+ T cells (Supplementary Fig. 5e) in KC/Pd mice compared to the KC littermates at 9 days of treatment, and KC/Pd mice had lower B-cell accumulation than KC mice did at 9 days of GW treatment, but this trend failed to reach statistical significance (Supplementary Fig. 5f).
