Expression of TLR4 in retinal vessel of diabetic mice. Immunofluorescence staining of TLR4 (green) and CD31 (red) was performed in normal and diabetic mouse retinas. a, c Representative results from three independent experiments with four diabetic and control animals in 6 week-group (a) or 8 week-group (c) after STZ injection are shown. b, d TLR4 immunofluorescence relative intensity in retinal sections of 6 week-group (b) or 8 week-group (d) of diabetic mice was quantified. *P < 0.05 compared to the control group. Scale bar 50 μm
