Tóm tắt

Sự ức chế viêm ruột mãn tính bởi các kiểu tế bào T khác nhau đã được mô tả trong những năm gần đây. Đặc biệt, các tế bào T điều hòa CD4+CD25+ tự nhiên và các tế bào T lympho CD4+ loại 1 sản xuất IL-10 đã được đề cập đến trong việc điều hòa viêm ruột. Ở đây, chúng tôi tập trung vào khả năng của các tế bào T điều hòa CD4+CD25+ trong việc ức chế phản ứng miễn dịch bẩm sinh và phản ứng tế bào T, đồng thời thảo luận về các tác động đối với điều hòa miễn dịch trong bệnh lý viêm ruột ở người. Ngoài việc điều chỉnh sự tăng sinh lympho, vai trò của các tế bào T CD4+CD25+ trong việc giảm bớt phản ứng miễn dịch bẩm sinh đang nổi lên, và các hoạt động điều hòa miễn dịch của các tế bào T điều hòa in vivo có thể được trung gian thông qua các tác động lên tế bào hình nhật. Xét về khả năng tái tạo phi thường của niêm mạc ruột, khả năng cản trở phản ứng của tế bào T gây bệnh thông qua việc điều chỉnh chủ động có thể mang lại lợi ích trị liệu quan trọng cho việc điều trị các bệnh viêm ruột mãn tính như bệnh Crohn và viêm loét đại tràng.
