The co-expression of CXCR3 and CCR6 on CD4+ T-cells was also lower in patients with AMD (p = 0.028, Kruskal Wallis’ test; p = 0.016, Mann-Whitney U-test between control and exudative AMD; p = 0.052, Mann-Whitney U-test between control and non-exudative AMD). Here, CD4 is linked to age-related macular degeneration.
