Tóm tắt

Các tế bào T-helper (Th) 22 và Th17 có liên quan đến diễn tiến bệnh sinh của các bệnh tự miễn. Vai trò của các tế bào Th22 trong sinh lý bệnh của bệnh viêm khớp dạng thấp (RA) vẫn chưa được làm rõ. Các tế bào CD4+IFNγ−IL17−IL-22+ (tế bào Th22), CD4+IFNγ−IL-22−IL17+ (tế bào Th17 thuần khiết), CD4+IL17+ (tế bào Th17) và CD4+IFNγ+ (tế bào Th1) ở bệnh nhân RA, bệnh nhân viêm khớp dạng thoái hóa và nhóm đối chứng khỏe mạnh đã được khảo sát bằng phương pháp phân tích dòng tế bào. Mức độ IL-22 và IL-17 trong huyết thanh đã được kiểm tra bằng phương pháp enzyme-linked immunosorbent assay. Các tế bào Th22, tế bào Th17 thuần khiết, tế bào Th17 và interleukin-22 đều tăng đáng kể ở bệnh nhân RA so với bệnh nhân viêm khớp dạng thoái hóa và nhóm đối chứng khỏe mạnh, nhưng không có sự khác biệt đáng kể về tế bào Th1 và interleukin-17. Các tế bào Th22 cho thấy sự tương quan dương tính với interleukin-22 cũng như với tế bào Th17 thuần khiết hoặc tế bào Th17 ở bệnh nhân RA. Ngoài ra, tỷ lệ phần trăm của các tế bào Th22, tế bào Th17 thuần khiết cũng như tế bào Th17 có tương quan dương tính với cả mức độ protein phản ứng C và chỉ số hoạt động bệnh ở 28 khớp. Tổng thể, kết quả của chúng tôi chỉ ra một vai trò khả dĩ của các tế bào Th22, tế bào Th17 thuần khiết và tế bào Th17 trong RA, và việc chặn kháng thể interleukin-22 có thể là một chiến lược điều trị hợp lý cho RA.
