Th-like Treg subsets, including Th1-like, Th2-like and Th17-like Tregs, as well as Th cell subsets in peripheral blood were assessed by flow cytometry.

Moreover, an imbalance of Th17-like Treg/Th17 cells was noted, characterized by a decreased frequency of Th17-like Tregs and an increased proportion of Th17 cells. Further analysis revealed a correlation between the frequency of Th2-like Tregs and the risk variants of IL-2RA rs3118470. Notably, T1D patients with a normal weight exhibited a higher frequency of Th1-like Tregs compared to their lean and overweight counterparts. However, Treg plasticity was not associated with disease characteristics. Additionally, the serum levels of IL-1β, TNF-α and IL-6 in T1D patients were significantly higher than those in HCs, and the proportions of Th1-like and Th2-like Tregs were negatively associated with IL-6 and TNF-α concentrations in T1D patients, respectively.
