Human T-Lymphotropic Virus Type 1: (HTLV-1)
Introduction
This section will include an overview of the virus including history and current research
The human T-lymphotropic virus type 1 (HTLV-1) was the first oncogenic human retrovirus to be discovered. It was first studied in 1977. The virus can cause adult T-cell leukemia/lymphoma (ATL) and progressive nervous system condition known as HTLV-1-associated myelopathy or tropical spastic paraparesis (HAM/TSP)along with other neurodegenerative diseases. Although HTLV is known for being associated with lymphoma and leukemia, it more commonly causes a range of neurological disorders due to the types of cells that are infected. .
Tropical spastic paraparesis (TSP), is a medical condition that causes weakness, muscle spasms, and sensory disturbance by human T-lymphotropic virus resulting in paraparesis, weakness of the legs. As the name suggests, it is most common in tropical regions, including the Caribbean
Structure
This section will include the structure of the virus
Human T-Lymphotropic Virus is part of the Delta-type retrovirus group. HTLVs are enveloped viruses with a diameter of approximately 80–100 nm. The HTLV virions contain two covalently bound genomic RNA strands, which are complexed with the viral enzymes reverse transcriptase, integrase and protease, and the capsid proteins. The outer part of the virions consists of a membrane-associated matrix protein and a lipid layer intersected by the envelope proteins. The viral genome
