Quizplus · Accepted Answer

Human T-cell lymphotropic virus type I (HTLV-I) preferentially infects CD4 T lymphocytes. HTLV-I is a retrovirus that targets T cells and can cause a range of diseases, including adult T-cell leukemia/lymphoma (ATLL) and HTLV-associated myelopathy/tropical spastic paraparesis (HAM/TSP). Infection with HTLV-I is typically chronic and can lead to T-cell dysfunction and proliferation, resulting in the development of ATLL or HAM/TSP in some individuals.
