Evaluation of senescence-associated characteristics of T cells from the offspring of vehicle and TCDD-treated dams during IAV infection. Adult (6–8 wk of age) developmentally exposed mice were infected with IAV. Mediastinal lymph nodes (MLNs) were analyzed 9 d after infection. (A,C,E,G) The number of T cells from vehicle (7 mice) or TCDD (8 mice for KLRG1 and p16; 3 mice for CD107a and perforin) developmentally exposed offspring that express (A) KLRG1, (C) p16, (E) CD107a, or (F) perforin are shown as bar graphs. (B,D,F,H) Scatter plots show the percentage of (B) , (D) , (F) , or (H)
T cells from infected mice that were developmentally exposed to vehicle (left) or TCDD (right). The numerical information is provided in Table S2. All offspring within a group were from separate dams. Values are . *,
, using Student’s -test. Note: CD107a, lysosomal-associated membrane protein 1; IAV, influenza A virus; KLRG1, killer cell lectin-like receptor subfamily G member 1; p16, cyclin-dependent kinase inhibitor 2A; SEM, standard error of the mean; SSC-A, side scatter area; TCDD, 2,3,7,8-tetrachlorodibenzo--dioxin.
