摘要

It is estimated that between 10 and 20 million people worldwide are infected with the human T- cell leukemia virus, type I (HTLV-I). Since HTLV-I is associated with a variety of human diseases, including an aggressive lymphoproliferative disorder named adult T-cell leukemia, infection by HTLV-I has become increasingly recognized as an important public health concern. Malignant transformation associated with HTLV-I infection is linked with the synthesis of a virally-encoded protein called Tax. In this review, we will highlight our current understanding of Tax protein function, both in its role as an activator of HTLV-I transcription and deregulator of cellular homeostasis. It is widely believed that Tax deregulation of cellular gene expression and cell cycle progression accounts for the pathogenicity associated with HTLV-I infection.
