AI Article Synopsis

  • - The study investigates the anti-inflammatory effects of recombinant human lactoferrin (rhLf) and its hydrolysate at levels similar to those in human milk, using a co-culture model of CaCo-2 and RAW 246.7 cells.
  • - Researchers assessed the integrity of cell layers and the production of inflammatory markers (like ROS and specific cytokines) after treating cells with rhLf, finding that it helped protect cell layers and reduce inflammation, with the hydrolysate showing stronger effects at 2mg/mL.
  • - The findings suggest adding rhLf and its hydrolysate to infant formula could enhance its health benefits for newborns, and further studies are underway to explore different methods to understand these effects better.*

Article Abstract

This study aimed to evaluate the potential anti-inflammatory role of the most produced form of lactoferrin expressed in various expression systems (Fe-saturated recombinant human Lf, rhLf) and its hydrolysate in concentrations resembles that found in mature human milk. Co-culture model consisted of CaCo-2 and RAW 246.7 cell lines was used to evaluate the potential anti-inflammatory activity of rhLf and its hydrolysate. During this experiment, CaCo-2 monolayer permeability and integrity was assayed through the measurement of transepithelial electrical resistance (TEER values). Also, the production of reactive oxygen species (ROS), nitric oxide (NO) and different cytokines (IL-8, IL-1β, IL-6, IL-10, IL-12p70, and TNF-α) were measured. The treatment with rhLf and its hydrolysate protected the monolayer integrity against LPS effect and reduced IL-8 and ROS production. This effect was dependent on the dose and 2mgmL of rhLf hydrolysate was more effective. The addition of rhLf and its hydrolysate to infant formula is a prominent step towards improving both infant formula functionality and newborn health. Thus, these functional ingredients could be incorporated in infant foods. In this context, ongoing researches are conducted to clarify this effect whether by using synthetic peptides or by using LPS-sepsis animal.
