Human T-lymphotropic virus

The human T-lymphotropic virus, human T-cell lymphotropic virus, or human T-cell leukemia-lymphoma virus (HTLV) family of viruses are a group of human retroviruses that are known to cause a type of cancer called adult T-cell leukemia/lymphoma and a demyelinating disease called HTLV-1 associated myelopathy/tropical spastic paraparesis (HAM/TSP). The HTLVs belong to a larger group of primate T-lymphotropic viruses (PTLVs). Members of this family that infect humans are called HTLVs, and the ones that infect Old World monkeys are called Simian T-lymphotropic viruses (STLVs). To date, four types of HTLVs (HTLV-1, HTLV-2, HTLV-3, and HTLV-4) and four types of STLVs (STLV-1, STLV-2, STLV-3, and STLV-5) have been identified. HTLV types HTLV-1 and HTLV-2 viruses are the first retroviruses discovere
