How a mom’s inflammatory fats and lung microbes may raise a child’s allergy risk
Development of allergy in offspring is enhanced by maternal eicosanoids and lung microbiota composition dysbiosis.
This project looks at whether higher levels of a type of inflammatory fat (called DHET) and changes in a mother's lung microbes increase a child's chance of developing allergies or asthma.

What this research studies
Researchers will use mouse models and laboratory tests to follow how DHETs produced by allergic mothers reach offspring and influence developing immune cells. They will study lung microbiota and perform transfer experiments where lung dendritic cells or microbes from newborns of allergic mothers are given to other pups to see if allergy responses transfer. The team will measure DHETs using lipidomics and compare findings to human cord blood samples that were linked to infant wheeze. Together these approaches aim to show how maternal factors shape infant immune development and allergy risk.
Who could benefit from this research
Good fit: Pregnant people with a history of allergic disease or asthma and their newborns (for cord blood or related samples) would be the most directly relevant participants.
Not a fit: People without a personal or parental history of allergic disease or older children past the newborn period are unlikely to receive direct benefit from this research.
Why it matters
Potential benefit: If confirmed, this work could point to maternal markers or interventions to lower children's allergy and asthma risk.
How similar studies have performed: Preliminary animal experiments and small human cord blood analyses suggest links between maternal DHETs, lung microbes, and infant wheeze, but the mechanisms are largely novel and remain unproven.
