Figure 3. Anti-viral CD8 responses are compromised by activation of plasma membrane TLRs.
(A) Mice that received OT-I CD8 T cells were infected using VSV-OVA or VSV-OVA mixed with different TLR ligands or live/heat killed Salmonella typhimurium (Sal/Sal-HK) and draining lymph nodes and the spleen were harvested on day 7 after infection to measure OT-I CD8 T cell expansion. (A, C, E). Representative plots show CD8 T cells that express GFP and stain positive for Kb-SIINFEKL tetramer. (B, D, F). Mean ± SEM of GFP-OT-I T cells as a percentage of total CD8 T cells from 5 independent mice per group. The data are representative of three (A, B, C and D) or two independent experiments (E and F). *, P < 0.05; **, P < 0.01; ***, P < 0.005.
