How T cells grow and protect babies and children

Evolution of T cell immunity in blood and tissues over childhood

NIH-funded research Columbia University Health Sciences · NIH-11284033

What this research studies

Your child's blood or donated tissue would be studied to see how T cells in different organs develop and settle into place during infancy and childhood. Researchers will compare T cells from blood and from tissues obtained from pediatric organ donors and look for the types that stay in tissues to protect against infection. Lab models and detailed lab tests will help explain how these tissue-resident memory T cells form and change as children grow. The goal is to understand what a strong, lasting T cell response looks like at different ages.

Who could benefit from this research

Good fit: Ideal candidates are newborns, infants, and children up to about 11 years old (or families willing to donate pediatric blood or tissue samples, including from organ donors).

Not a fit: Adults outside the pediatric age range or patients who cannot or do not provide blood or tissue samples are unlikely to directly benefit from participation.

Why it matters

Potential benefit: If successful, this work could help design better vaccines and immunotherapies that protect infants and children by targeting the right T cell responses.

How similar studies have performed: Previous studies, including work using pediatric organ donor tissues, have identified tissue-resident memory T cells in humans, but tracking how they form and mature across childhood is a relatively new area.
