In this report, we evaluated the effect of the pasteurization (P) process of mother’s own milk (MOM) on the miRNA content of extracellular vesicles (EVs) and its impact on innate immune responses. Differences in size or particle number were not observed upon pasteurization of MOM (PMOM). However, significant differences were observed in the EV membrane marker CD63 and miRNA profiles. miRNA sequencing identified 33 differentially enriched miRNAs between MOMEV and PMOMEV. These changes correlated with significant decreases in the ability of PMOMEV to modulate IL-8 secretion in intestinal Caco2 cells where only MOMEV were able to decrease IL-8 secretion in presence of TNFα. While EVs from MOMEV and PMOMEV were both able to induce a tolerogenic M2-like phenotype in THP-1 macrophages, a significant decrease in the transcript levels of IL-10 and RNA sensing genes was observed with PMOMEV. Together, our data indicates that pasteurization of MOM impacts the integrity and functionality of MOMEV, decreasing its EVs-mediated immunomodulatory activity. This data provides biomarkers that may be utilized during the optimization of milk processing to preserve its bioactivity.
