Mapping variants in HTLV-1 genome to analyze their impacts on the HAM/TSP development: A systematic review.

The reasons that lead some individuals living with the Human T Lymphotropic Virus 1 (HTLV-1) to develop HAM/TSP are still unclear. To better understand the viral genetic factors that may be associated with the development of HAM/TSP, this study aims to evaluate the impact of HTLV-1 genome mutations on the development of this disease through a systematic review. This review followed the PRISMA guidelines and was registered in the PROSPERO database.

Advances in preventive vaccine development against HTLV-1 infection: A systematic review of the last 35 years.

Introduction: The Human T-lymphotropic virus type 1 (HTLV-1) was the first described human retrovirus. It is currently estimated that around 5 to 10 million people worldwide are infected with this virus. Despite its high prevalence, there is still no preventive vaccine against the HTLV-1 infection.

An overview of sequencing technology platforms applied to HTLV-1 studies: a systematic review.

Human T-lymphotropic virus type 1 (HTLV-1) was the first human retrovirus described. The viral factors involved in the different clinical manifestations of infected individuals are still unknown, and in this sense, sequencing technologies can support viral genome studies, contributing to a better understanding of infection outcome. Currently, several sequencing technologies are available with different approaches.

Molecular characterization of HTLV-1 genomic region hbz from patients with different clinical conditions.

The human T-cell lymphotropic virus type-1 (HTLV-1) is associated with severe pathologies, such as HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP), adult T-cell leukemia-lymphoma (ATLL), and infective dermatitis associated with the HTLV-1 (IDH). Interestingly, HTLV-1 infection does not necessarily imply the development of pathological processes and it is unknown why some patients remain asymptomatic carriers (AC). Despite some mutations in the HTLV-1 genome appear to influence the outcome of HTLV-1, there are few studies that characterize molecularly the hbz region.
