Abstract

Cranberry contains high levels of nutrients and bioactive molecules that have health-promoting properties. The purpose of the present studies was to determine if cranberry extracts (CEs) contain phytochemicals that exert anti-inflammatory effects. The human monocytic cell line THP-1 was treated with two CEs (CE and 90MX) and subsequently challenged with Lipopolysaccharides (LPS). Tumor necrosis factor α (TNFα) expression was decreased in the CE-treated cells, indicative of an anti-inflammatory effect. Gene expression microarrays identified several immune-related genes that were responsive to CEs including interferon-induced protein with tetratricopeptide repeats 1 and 3 (IFIT 1 and 3), macrophage scavenger receptor 1 (MSR1) and colony-stimulating factor 2 (CSF2). In addition, in the CE-treated cells, metallothionein 1F and other metal-responsive genes were induced. Taken together, this data indicates that CEs contain bioactive components that have anti-inflammatory effects and may protect cells from oxidative damage.
