IL-15Rα (Interleukin-15 receptor α, CD215) expressed at lower levels in T1D B cells (Supplementary Fig. S5b), therefore we focused on the other two receptors, IL-15Rβ (Interleukin-15 receptor β, CD122) and IL-15R γc (Interleukin-15 receptor common γ chain, CD132). The gene discussed is IL15RA; the disease is type 1 diabetes mellitus.
