Understanding how breastfeeding T cells help protect infants from respiratory infections

Elucidating a novel respiratory-mammary axis of T cell immunity

NIH-funded research Seattle Children's Hospital · NIH-11054883

This study is looking at how T cells in breast milk might help protect babies from respiratory infections, and it’s for mothers and their infants to understand how breastfeeding can boost a baby's immune system.

What this research studies

This research investigates the role of T cells found in breast milk and their potential protective effects against respiratory infections in infants. By studying mother-infant pairs, the research aims to understand how maternal respiratory infections influence T cell populations in both the breast and the infant's respiratory tract. The methodology includes analyzing breast milk cells, nasal mucosal cells, and blood samples using advanced sequencing techniques to uncover the relationship between these T cells and immune responses. The ultimate goal is to clarify how breastfeeding may enhance an infant's immunity to respiratory illnesses.

Who could benefit from this research

Good fit: Ideal candidates for this research are breastfeeding mothers and their infants, particularly those under 11 years old.

Not a fit: Patients who are not breastfeeding or whose infants are older than 11 years may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to improved strategies for enhancing infant immunity and reducing respiratory infections in young children.

How similar studies have performed: Previous research has shown promising results in understanding the immune benefits of breastfeeding, but this specific investigation into T cells in breast milk is relatively novel.
