Figure 7. Limited dilution bone marrow chimeras reveal a minor role for TCR specificity in lineage preference of iNKT cells.
Jα18−/− mice were lethally irradiated, reconstituted with 95% Jα18−/− bone marrow and 5% bone marrow of the indicated TN lines, and analyzed 8 weeks later. n=4 mice per group. (A) Skin draining lymph node cells from all TN mice were stimulated in vitro with PMA/Ionomycin for 4 hours, in the presence of GolgiStop. Cells were stained with anti-CD3 and CD1d (PBS57) tetramer, before being fixed, permeabilized, and stained with antibodies to IFNγ, IL-4, and IL-17. Results shown are gated on CD3+CD1d-tetramer+ cells. (B) Quantification of ICCS data from thymus, spleen, skin-draining lymph nodes and liver, normalized to Vα14 values for the same organ. Error bars are SD.
