Figure 5. Dynamic changes in ADORA2BR protein levels upon 7-MX treatment. A: Human RPE cells were treated with 10 μmol/l 7-methylxanthine (7-MX) for 24 and 48 h. ADORA2B protein levels were detected with immunofluorescence. B: The mean fluorescence intensity of ADORA2B was decreased statistically significantly at 48 h compared to 0 h (p<0.05).
