In vivo analysis of replication and immunogenicity of proviral clones of human T-lymphotropic virus type 1 with selective envelope surface-unit mutations.

Human T-lymphotropic Virus Type I (HTLV-I) Proviral Load and Clinical Features in Iranian HAM/TSP Patients

P178: Can Human T-Lymphotropic Virus Proviral Load Predict the Severity of Clinical Features in HAM/TSP Patients?

HTLV-1 is the causative agent for a neurologic disease named HTLV-I- associated myelopathy/tropical spastic paraparesis (HAM/TSP). Paraparesis of the lower limbs which appears gradually is the most common clinical feature of this disease. The indirect involvement of the nervous system by lymphocytes is more probable than the direct attack of the virus to the neurons. The proviral load (PVL) is ...

High proviral load of human T cell lymphotropic virus type-1 facilitates coronary artery diseases

Objective(s): Coronary artery disease (CAD) is known as a life threatening disease, worldwide. In this study the role of HTLV-1 infection was evaluated on cardiac involvement in an endemic region of northeastern Iran.Materials and Methods: Serologic and molecular tests for HTLV-1 infection were carried out in subjects who had coronary an...

Dengue virus type-3 envelope protein domain III; expression and immunogenicity

Objective(s): Production of a recombinant and immunogenic antigen using dengue virus type-3 envelope protein is a key point in dengue vaccine development and diagnostic researches. The goals of this study were providing a recombinant protein from dengue virus type-3 envelope protein and evaluation of its immunogenicity in mice. Materials and Methods: Multiple amino acid sequences of different i...

Deep Sequencing Analysis of Human T Cell Lymphotropic Virus Type 1 Long Terminal Repeat 5' Region from Patients with Tropical Spastic Paraparesis/Human T Cell Lymphotropic Virus Type 1-Associated Myelopathy and Asymptomatic Carriers.

The aim of this study was to analyze patients by deep sequencing the human T cell lymphotropic virus type 1 (HTLV-1) long terminal repeat (LTR) region in order to determine if minor and/or major mutations in this promoter region might be associated with tropical spastic paraparesis (TSP)/human T cell lymphotropic virus type 1-associated myelopathy (HAM) outcome or proviral load or HTLV-1 expres...
