We then assessed frequencies of total ILCs, ILC1, ILC2, ILC3, and the cytokine responses of the ILC sub-sets including IFN-γ, IL-13 and IL-22 by flow cytometry on PBMCs from patients with LTBI and T2DM (n=13), LTBI (n=14), T2DM (n=10) and HC (n=11) (Table 1). The gene discussed is IFNG; the disease is type 2 diabetes mellitus.
