Transactivation of the human interleukin-6 gene by human T-lymphotropic virus type 1 Tax protein.

Interleukin-6 (IL-6) is a multifunctional cytokine that regulates both humoral and cellular immune responses. Accumulating evidence suggests that the infection of T cells and other cell types with human T-lymphotropic virus type 1 (HTLV-1) results in the constitutive expression of IL-6. However, the underlying molecular mechanisms are little understood. When a reporter plasmid, pIL6-CAT-E3, in ...

Inhibition of p53 transactivation function by the human T-cell lymphotropic virus type 1 Tax protein.

Human T-cell lymphotropic virus type 1 (HTLV-1) is the etiologic agent for adult T-cell leukemia. HTLV-1 transforms lymphocytes, and there is increasing evidence that the virus-encoded protein, Tax, plays a primary role in viral transformation. We have shown that wild-type p53 in HTLV-1-transformed cells is stabilized. This study was initiated to directly analyze whether the p53 in HTLV-1-trans...

Evaluating the Frequency of Human T-Lymphotropic Virus Type 1 Infection in Iranian Population

Background: Human T-cell lymphotropic viruses 1 (HTLV1) is endemic in specific regions. We aimed to determine the prevalence of HTLV I infection among blood donors in southeast Iran.   Methods: This cross-sectional study was conducted between April 2005 and March 2015. Sera were collected from blood donors and were tested for the presence of HTLV1 specific antibody using ELISA. Reactive sample...
