Longitudinal transcriptional profiling of CD8 cells in response to infection and vaccination across tissues. Longitudinal transcriptional profiling of CD8 cells in response to infection and vaccination across tissues

To determine whether persistent antigen in AdNP immunized mice has any potential cell-intrinsic effects on the genetic program of lung TRM that result in their enhanced longevity, we compared the transcriptional profiles of influenza NP-specific lung TRM (CD8+ i.v. antibody- NP+ CD69+ CD103+), lung TRM that were CD69 single positive (CD8+ i.v. antibody- NP+ CD69+ CD103-) and splenic TEM (CD8+ CD62L- NP+) from mice either infected with x31 influenza or immunized with AdNP at 1-month (35 days post-infection (d.p.i.), x31 and AdNP) and 1-year (365 d.p.i., AdNP only) time points. Overall design: Transcriptional profiling of 9 experimental groups with 2 samples per group.
