Aronia (Aronia melanocarpa) Polyphenols Modulate the Microbial Community in a Simulator of the Human Intestinal Microbial Ecosystem (SHIME) and Decrease Secretion of Proinflammatory Markers in a Caco-2/endothelial Cell Coculture Model
Abstract
To explore the mechanisms behind the health effects of Aronia (Aronia melanocarpa), the microbial community modulating and anti-inflammatory effects of Aronia polyphenols are investigated by combining the similutor of the human intestinal microbial ecosystem (SHIME) with a coculture of intestinal and endothelial cells. Administration of Aronia juice (6.5g L-1 ) to the SHIME for 2 weeks increases the abundance of firmicutes to 92% in the ascending colon (AC), 85% in the transverse colon (TC), and 82% in the descending colon (DC; p < 0.001), proteobacteria (6.7% in AC, p < 0.001), and Akkermansia (14% in TC and 18% in DC, p < 0.001) and decreases the abundance of Bifidobacterium species, associated with a decrease of acetate and increase of propionate and butyrate, whereas no significant difference is observed upon placebo juice treatment. After addition of the digests to TNF-α challenged Caco-2/endothelial cocultures, intercellular adhesion molecule (ICAM)-1, IL-8, and monocyte chemoattractant protein-1 levels are significantly downregulated. Interestingly, Aronia juice treats digests from each colon compartment resulting in a stronger decrease of the ICAM-1 secretion (up to 73%, p < 0.001) compared to their corresponding placeb...Continue Reading

Adhesion Molecules in Health and Disease
Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.

Anti-inflammatory Treatments
A drug or substance that reduces inflammation (redness, swelling, and pain) in the body. Anti-inflammatory agents block certain substances in the body that cause inflammation and swelling. Discover the latest research on anti-inflammatory treatments here
