1) Division plane parallel to IS only in 10% of CD4+ T cells.2) No asymmetry in CD3, CD4, CD62L, CD95, CD127, CD132, and HLA-DR.3) Through GLUT1 upregulation, IL-7 increased asymmetric division rates in autoreactive T cells from patients with T1D. This evidence concerns the gene IL2RG and type 1 diabetes mellitus.
