Tóm tắt

Virus viêm gan C (HCV) là một trong những nguyên nhân chính gây ra ung thư tế bào gan (HCC) trên toàn thế giới. HCV thúc đẩy các đặc tính của tế bào gốc ung thư và các tế bào bị nhiễm không nhạy cảm với các tín hiệu apoptosis, dẫn đến tình trạng kích thích kháng nguyên kéo dài và kiệt quệ tế bào T trong cơ thể chủ. Mặc dù đã có những loại thuốc kháng virus hiệu quả mới, các thách thức mới đang gần kề khi các chủng virus kháng thuốc và các tương tác giữa các loại thuốc đã được báo cáo. Xét rằng có rất ít phương pháp điều trị hiệu quả cho HCC, các liệu pháp miễn dịch mới nhằm ngăn ngừa HCC và các bệnh gan liên quan đến HCV giai đoạn muộn nên được xem xét. Xét rằng liệu pháp miễn dịch nhận tạo với các lympho T đặc hiệu kháng nguyên đã nổi lên như một chiến lược điều trị hiệu quả để chống lại ung thư, do đó có lý do để xem xét khả năng sử dụng các tế bào T phản ứng HCV có chức năng cao trong liệu pháp miễn dịch. Bài tổng quan này nhằm mục đích cung cấp sự hiểu biết hiện tại về các tế bào T phản ứng tự nhiên trong nhiễm HCV và cập nhật về các phương pháp mới có khả năng sản xuất các tế bào T có chức năng cho liệu pháp tế bào nhận tạo. Các phương pháp dựa trên sự làm giàu từ tính liên kết với tetramer pMHC, chuyển giao thụ thể tế bào T HCV ngoại sinh, và công nghệ tế bào gốc cảm ứng đa năng được mô tả trong bài viết này. Tiềm năng của chúng như một liệu pháp miễn dịch chống lại các bệnh liên quan đến HCV được thảo luận.
