Osteopontin and the early life immune function
Osteopontin (OPN) is a whey protein believed to play a role in the early life immune function 1 2 3 4 5. An acidic glycoprotein with strong calcium-binding properties, it is present in human milk at a higher concentration than in bovine milk6,7 and, subsequently, early life nutrition products.
Arla Foods Ingredients holds several patents for the production and application of high-purity OPN in the form of Lacprodan® OPN-10, the first OPN product on the market.
In two clinical it was found that infant formula enriched with Lacprodan® OPN-10 encouraged similar . Additionally, compared to infants fed a standard infant formula, r, pro-inflammatory cytokine TNFα levels to be reduced 8, the number of circulating immune cells (monocytes and T cells) to be increased, and shifted gene expression of immune cells to be more similar towards breast-fed infants 9.
Also, three preclinical studies found that dietary supplementation with Lacprodan® OPN-10 boosted the immune response induced by vaccination10, lowered proinflammatory cytokine TNFa levels11, enhanced intestinal growth 11 and brought intestinal gene expression closer to that of breastfed animal groups 12.
Lacprodan® OPN-10: approved in the EU
In February 2022, the European Food Safety Agency (EFSA) granted a positive opinion on our Novel Food application for Bovine Milk Osteopontin ingredient Lacprodan® OPN-10. In its scientific opinion, the Authority concluded that bovine milk osteopontin is safe.
In March 2023 we have secured the final Novel Food approval for Lacprodan® OPN-10 for use in infant, follow-up and young child formulas making our product the first osteopontin product available in the EU.
