Evidence that medLN TRM can participate in a secondary response. (A) In vitro proliferation of bead-enriched, Ly6Cneg medLN P14 cells compared with Ly6C+ P14 cells pooled from peripheral (Periph.) LNs. Left: Ly6C phenotype of medLN P14 cells before (black) and after (red) bead enrichment. Right: CTV dilution and phenotype of medLN TRM 68 h after in vitro peptide stimulation. Data are representative of two independent experiments. (B) Congenically distinct circulating (CD103neg CD45.1) and resident (CD103+ Thy1.1) memory P14 cells were sorted from the medLN using an approach obviating Thy1.1 (depleting) antibody. Host medLN CD8+ T cells were excluded based on CD45.2 expression. (C) Abundance of Thy1.1 and CD45.1 P14 cells in the indicated tissues 7 d after systemic LCMV infection. (D) CD103 and integrin-β7 phenotype on CD45.1 and Thy1.1 P14 cells isolated from the indicated tissues 7 and 60 d after systemic LCMV infection (n = 4). Error bars represent mean ± SEM.
