Mathew, Romain Gailleton, Lydia Scharf, Karin Schön, Anneli Strömberg, Nils Lycke, Mats Bemark, Ka-Wei Tang, Davide Angelettihttps://doi.org/10.1101/2024.07.06.602325 CD4 tissue-resident memory T (CD4 TRM) cells are crucial adaptive immune components involved in preventing influenza A virus (IAV) infection. Despite their importance, their physiological role in the upper respiratory tract, the first site of contact with IAV, remains unclear. Here, we find that, after IAV infection, antigen-specific CD4 TRM persist in the […]
