The effect of Id proteins on Vδ6.3+ γδ T cells is mediated by E proteins and is developmental stage-specific. (A) Although conditional knockout of both Id2 and Id3 limits the accumulation of Vδ6.3+ γδ T cells in the thymus, further deletion of HEB and/or E2A can restore the accumulation of those cells. N≥3 for each group. (B) Deletion of all alleles of HEB, E2A, Id2 and Id3 by CD4Cre can induce accumulation of Vδ6.3+ γδ T cells, but deletion by LckCre fails to induce a similar phenotype. N≥3 for each group. All error bars indicate SD.
