OBJECTIVES: Myasthenia gravis (MG) is an autoimmune disease accompanied by a thymic pathology and in most patients thymectomy (TE) is used as the therapeutic approach. Both B and T cells play an important role in MG pathogenesis.
METHODS: Twelve pre- and post-TE MG patients and 12 healthy controls (HCs) were enrolled. The mean percentages of Th22 and Tc22 cells were evaluated in MG patients (before and 6 months after TE) and HCs.
RESULTS: The mean percentage of Tc22 cells in pre-TE patients was significantly higher than in HCs (p < 0.05), and after TE Tc22 cells significantly decreased compared to pre-TE (p < 0.05). The frequency of Th22 cells in pre-TE MG patients was not significantly different from HCs, but after TE Th22 cells were significantly decreased compared to pre-TE (p < 0.05).
CONCLUSION: Our findings suggest a possible role of Th22 and Tc22 in MG pathogenesis.
