The percentage of oligomannose N-glycans in CD4+CD25+ cells from Hashimoto’s thyroiditis patients was about twice as high as in the CD4+CD25- pool, while complex-type glycans were in HT2 group significantly more abundant in CD4+CD25- cells than in CD4+CD25+ (Figure 7A). Here, CD4 is linked to Hashimoto thyroiditis.
