Given the central role that interleukin 15 (IL-15) plays in human immunodeficiency virus (HIV) immunity, we hypothesized that IL-15 in breast milk may protect against postnatal HIV transmission. In a nested case-control study, we compared breast milk IL-15 levels in 22 HIV-infected women who transmitted HIV to their infants to those in 72 nontransmitters. Samples were collected in the first month of life, prior to HIV infection. IL-15 concentrations were associated with a decreased risk of HIV transmission in unadjusted analysis and after adjusting for milk viral load, CD4 cell count, and other cytokines in breast milk. IL-15-mediated immunity may protect against HIV transmission during breast-feeding.

Effects of Food Processing on Allergenicity.

Curr Allergy Asthma Rep

January 2025

Temerty Faculty of Medicine, University of Toronto, Toronto, ON, Canada.

Purpose Of Review: There is an increasing awareness among clinicians that industrial and household food processing methods can increase or decrease the allergenicity of foods. Modification to allergen properties through processing can enable dietary liberations. Reduced allergenicity may also allow for lower risk immunotherapy approaches.

Breast milk is essential for infant health, but the transfer of xenobiotic chemicals poses significant risks. Ethical challenges in clinical trials necessitate the use of in vitro predictive models to assess chemical exposure risks in breastfeeding infants. This study introduces an explainable machine learning model to predict the risk of chemical transfer through human milk.

We hypothesized that improving the fat globule structure of infant formulae based on the milk fat globule membrane (MFGM) would regulate metabolites and metabolic pathways, making it more similar to the metabolic properties of human milk. Therefore, we prepared infant formulae with different fat globule structures, including two model infant formulae (F1: fat globules surrounded by MFGM; F2: fat globules surrounded by protein) and one commercial infant formulae containing MFGM, and compared their metabolic differences with those of human milk. The number of differential metabolites between each sample and human milk reached 60 (F1), 132 (F2) and 126 (IF1).

Article Synopsis
  • Human milk (HBM) and bovine milk (PBM) are both sources of nutrition that involve lactose, which can be fermented by the bacteria Streptococcus mutans, potentially affecting dental health.
  • This study compares how S. mutans forms biofilms, produces acid, and buffers in HBM, plain and sweetened PBM, and infant formula (IF) through various microbiological assays.
  • Results indicated that sweetened bovine milk had the highest biofilm formation and lowest pH, while both HBM and PBM showed low cariogenicity, differing from the effects of sucrose.
