TCRVαβ transgene pair impacts on cytokine production and transcriptional profile. (A) TCRαβ transgenics or littermate controls were primed with peptide in CFA and DLN cells harvested at Day 10. 3H-thymidine incorporation and cytokine production was determined from TCRαβ transgenics (filled triangles; n = 6) and controls (filled squares; n = 10). Error bars indicate ± SE. This is representative of three separate experiments. (B) TCRαβ transgenic cell lines (black bars) (n = 3) and littermate control lines (white bars) (n = 5) were established from primed DLN cells from mice primed 10 days earlier with PLP56 to 70/CFA and re-stimulated every 10 days through to four cycles in the absence of any exogenous polarization. (C) At each re-stimulation the relative expression of IFNγ, GATA-3 and RORγT was determined. Error bars indicate SE. (D) TCRαβ (filled triangles; n = 10), TCRα chain transgenics (filled circles; n = 12), and littermate controls (filled squares; n = 27) were primed with peptide/IFA and at Day 10, DLN cells were harvested and 3H-thymidine incorporation and cytokine production analyzed. These data are representative of three independently performed experiments. CFA, Complete Freund’s adjuvant; DLN, draining lymph nodes.
