Figure 5From: Per os administered refined olive oil and marine PUFA-rich oils reach the cornea: possible role on oxidative stress through caveolin-1 modulationCaveolin-1 immunoreactivity (confocal microscopy). The cells were incubated with oleic acid during 24 hours and fixed. After permeabilization, caveolin-1 was immunostained. The expression of caveolin-1 protein becomes more punctuate and less diffuse after oleic acid treatment, compared to control.Back to article page
