Figure 5

Immunohistochemical staining with primary anti-TLR4 antibodies in the corneas (a, c, e, g, i, k, m, o) and retinas (b, d, f, h, j, l, n, (p)) of immunocompetent (a, b, e, f, i, j, m, n) and immunosuppressed mice (c, d, g, h, k, l, o, p) from control groups (0 dpi) and at 8, 16, and 24 days after Acanthamoeba spp. infection (dpi). Magnification x40 (black arrows: corneal epithelium; red arrows: external limiting membrane, Bowman’s membrane; white stars: stroma of cornea, substantia basalis; yellow arrows: Descemet’s membrane; blue arrows: corneal endothelium; white arrows: optic nerve fiber layer; green arrows: inner plexiform layer; orange arrows: outer plexiform layer; pink arrows: layer of rods and cones).
