Figure 3. Caffeine administration prevents the inflammatory response triggered by OHT.
The effects of caffeine administration on the retinal neuroinflammatory response in eyes subjected to OHT were evaluated by qPCR and ELISA. (A) mRNA expression of pro-inflammatory cytokines IL-1β and TNF were assessed by qPCR. Results are presented as fold change comparing with the control animals, and represent the mean ± s.e.m from 5–7 independent experiments. (B) The retinal protein levels of IL-1β and TNF were quantified by ELISA. Results are expressed in pg/μg of protein, and represent the mean ± s.e.m from 5–10 independent experiments. *p < 0.05, **p < 0.01 and ****p < 0.0001, significantly different from control animals; #p < 0.05, significantly different from water drinking animals with 3 days OHT; +p < 0.05, ++p < 0.01 and ++++p < 0.0001, significantly different from water drinking animals with 7 days OHT; Kruskall-Wallis test, followed by Dunn’s multiple comparison test.
