Many plant extracts are well known for their anti-oxidant, anti-bacterial and antiinflammatory
activities including Aronia berry-derived juices and powders. In
comparison to other black berries, Aronia berries have a greater content of phenolic
constituents such as procyanidins, anthocyanins and phenolic acids with antioxidative
and anti-inflammatory properties. However, the effects of aronia berries extract on the
immune response parameters have been only sporadically assessed. When administered
orally to healthy C57BL/6 mice (50 mg/kg body weight), aronia extract exerted
immunomodulatory effects as evidenced by decreased proportion of F4/80+
macrophages, CD11c+ dendritic cells, CD4+ T helper cells, CD8+ T cytotoxic
lymphocytes and CD4+CD25- activated lymphocytes within the gut-associated
lymphoid tissue. Surprisingly, oral consumption of chokeberry extract in doses of either
200 mg/kg bw or 50 mg/kg bw in mice with multiple low dose streptozotocin-induced
type 1 diabetes resulted in the increase of blood glucose levels. Further, our study shows
that this detrimental effect on type 1 diabetes pathogenesis may be a consequence of
the pro-inflammatory nature of the extract. This is based on the evident stimulation of
macrophages and dendritic cells by the extract through up-regulation of proinflammatory
mediators such as nitric oxide, IL-12, IL-6 and TNF in vitro. Also, this
extract augmented differentiation of IFN-γ-producing T helper 1 cells in vitro.
Collectively, the obtained results imply that our particular aronia berries fruit extract
displays pro-inflammatory characteristics and that care should be taken when these
berries are to be included in the human diet.
