Effects of ARPE-19-Jurkat cells co-culture on IL-1β evaluated as mRNA levels. IL-1β expression was significantly increased in both ARPE-19 (A) and Jurkat (B) cells after 16 h and 24 h of co-culture, respectively. The increment of IL-1β levels was maintained up to 48 h of co-culture. Data are expressed as mean ± SD of four independent experiments carried out in triplicate. **p < 0.01; ***p < 0.001; ****p < 0.0001 versus ARPE-19/Jurkat (Newman−Keuls test after ANOVA).
