How T cells change from infancy to adulthood

Mapping infant and adult T cell immunity

NIH-funded research Cornell University · NIH-11261765

Researchers will map where and how CD8+ T cells develop in lymph nodes from birth through adulthood to learn why infants and adults respond differently to infections.

What this research studies

This project will use advanced molecular and imaging tools to build a detailed atlas of CD8+ T cells in lymph nodes from newborns, children, and adults. The team will map the exact locations of T cells, identify which neighboring cells they interact with, and track how those patterns change with age. Investigators will compare early-life 'innate' niches near subcapsular macrophages with adult 'adaptive' niches in the paracortex to see how those differences affect immune protection. The work will rely on high-resolution spatial and molecular analyses of tissue samples to create a timeline of T cell development.

Who could benefit from this research

Good fit: Ideal candidates would be people across age groups (with parental consent for infants/children) who can provide lymph node tissue or blood samples and are willing to participate in research at the study sites.

Not a fit: People looking for immediate treatments or cures should not expect direct medical benefit because this is basic research focused on mapping immune cells rather than testing a therapy.

Why it matters

Potential benefit: If successful, this could point to new ways to improve infant immunity and guide better vaccine or therapy designs for different age groups.

How similar studies have performed: Related single-cell and spatial atlases have successfully revealed important immune organization in tissues, but applying these methods across ages to map CD8+ T cell niches from birth to adulthood is novel.
