ITGB2 and acute myeloid leukemia: CD4IL10 cells constitutively express high levels of CD18 [14] (ITGB2; Fig. S2) and CD11a [16] (ITGAL, Fig. S6E, F), which were not further upregulated in CD4IL10 cells interacting with killing-sensitive AML cells, and thus not identified by interaction analysis (Fig. 3C).
