Characterization of lung tissue-resident helper T cells. Characterization of lung tissue-resident helper T cells

To identify the characters of tissue resident CD4 T cells following influenza virus infection, we sorted lung CD45iv-CD4+CD44hi T cells from influenza PR8 infected mice (28 d.p.i.). Then the cells were performed single cell RNA sequencing. At the result, we found clera 5 differnt clusters and each cluster represent different helper T cell types including TH1, TH17 and Treg. One cluster exhibited both tissue residency and TFH cell features. So, we identify the characters of this hybrid lung CD4 T cells. Overall design: Examined with lung-resident CD4+ T cells sorted from influenza PR8-infected mice (28 days post infection)
