Study Identifies Long-Term T Cells in Nasal Tissue After Pathogen Infection
Researchers have found that nasal tissue contains T cells that retain memory of pathogens long after infection clears. The study, published in Nature, examined human nasal samples and mouse models to identify these resident memory T cells. This discovery provides insights into local immune responses in the upper respiratory tract.
