Research has identified a potential inverse correlation between coffee consumption and the risk of depression. The aim of this study was to investigate the effects of caffeinated coffee on lipopolysaccharide-induced depressive-like behaviors and inflammatory biomarkers in an in vivo model of depression in a C57BL/6J mouse model. The behavioral studies showed that caffeinated coffee decreased immobility time in both the tail suspension test (caffeinated coffee 56.60 ± 9.17; p < 0.0001) and the forced swimming test (caffeinated coffee 28.80 ± 5.93; p < 0.0001), suggesting antidepressant-like activity. The effects of caffeinated ...

The effects of caffeinated coffee on the inflammatory biomarkers associated with depression supported the results observed in the behavioral studies. Statistically significant decreases in indoleamine 2,3-dioxygenase activity (p < 0.001) and the neopterin/biopterin ratio (p < 0.001) were observed in animals pretreated with caffeinated coffee 24 h post-lipopolysaccharide exposure in comparison to the lipopolysaccharide control group. In conclusion, this study has provided evidence to suggest that caffeinated coffee has antidepressant-like activities; however, further studies are required to fully investigate these effects.
