BACKGROUND Human milk oligosaccharides (HMOs) are bioactive components of breast with diverse health benefits, including shaping the gut microbiota, modulating immune system, and protecting against infections. HMOs exhibit dynamic secretion patterns during lactation, influenced by maternal genetics environmental factors. Their direct indirect antimicrobial properties have garnered significant research interest. However, a comprehensive understanding dynamics their correlation efficacy remains underexplored. AIM To synthesize current evidence on lactation evaluate roles bacterial, viral, protozoal pathogens. METHODS A systematic search PubMed, Scopus, Web Science, Cochrane Library focused studies investigating natural synthetic HMOs, dynamics, properties. Studies involving human, animal, in vitro models were included. Data HMO composition, temporal patterns, mechanisms action extracted. Quality assessment was performed using validated tools appropriate for study design. RESULTS total 44 included, encompassing research. exhibited 2′-fucosyllactose (2′-FL) lacto-N-tetraose peaking early declining over time, while 3-fucosyllactose (3-FL) increased later stages. demonstrated through pathogen adhesion inhibition, biofilm disruption, enzymatic activity impairment. Synthetic bioengineered 2′-FL 3-FL, structurally functionally comparable to effectively inhibiting pathogens such as Pseudomonas aeruginosa , Escherichia coli Campylobacter jejuni . Additionally, synergistic effects antibiotics, enhancing resistant CONCLUSION vital defense, supporting infant targeting various Both hold potential therapeutic applications, particularly nutrition adjuncts antibiotics. Further research, clinical trials, is essential address gaps knowledge, validate findings, explore broader applicability improving neonatal health.
