NCT ID NCT06039527
First seen Nov 01, 2025 · Last updated Apr 30, 2026 · Updated 24 times
Summary
This study aims to understand why older adults, especially those who are frail, lose important immune cells (T cells) from their nasal passages, making them more prone to lung infections. Researchers will compare nasal and blood samples from 170 healthy young adults, healthy older adults, and frail older adults. The goal is to identify the mechanisms behind this cell loss and link it to infection risk, without offering any treatment.
