The isolation and characterization of a human T-cell lymphotropic retrovirus related to human T-cell lymphotropic virus type I (HTLV-I) from cerebrospinal fluid of a Jamaican patient with tropical spastic paraparesis is described. The virus isolate is a typical type C retrovirus as seen by electron microscopy and is related to prototype HTLV-I isolated from patients with adult T-cell leukemia b...

Human T cell leukemia virus (HTL V) is the name by which we have designated a family of related retroviruses from humans. HTLV type I (HTLV-I) is the name we gave the first human retrovirus isolate. HTLV-I is endemic at low rates in different parts of the world, including southern Japan, the Caribbean, South and Central America, the southeastern United States, and especially in Africa. Seroepid...

Human T-ceil lymphotropic virus, type 1 (HTL V-I) is considered to be the causative agent of adult T-cell lymphoma/leukemia and spastic paralysis, and seems to be common in Khorasan Province. 300 blood samples from Mashhadi and 180 from Gonbadi blood donors were obtained (all samples from healthy subjects). Serological screening was done by passive particJe- agglutination test and confirme...

Monoclonal antibody HT462 recognizes a human T-cell leukemia virus type I (HTLV-I)-associated Mr 52,000 glycoprotein (HA-gp52), which is found on the surface of HTLV-infected cells. Whether HA-gp52 is encoded by the virus or by the infected cells has not yet been established. Using monoclonal HT462 in a competitive binding assay, natural human antibodies specific for HA-gp52 were detected in 97...

It has been 25 years since the discovery of human T-cell leukemia virus type I (HTLV-I) and its role in adult T-cell leukemia. Here, in brief, we review the current state of our understanding of HTLV-I epidemiology, viral biology, pathogenesis, and treatment. We discuss how HTLV-I may transform cells through destabilization of cellular genomic integrity and induction of cellular tolerance for c...

Human T-cell lymphotropic virus type 1 , 2 (HTLV-1, 2) is endemic in Particular Areas of the world in which it is associated with myeloid leukemia.In this study, we described the prevalence of HTLV-1, 2 in myeloid leukemia and Mycobacterium Tuberculosis in Iran. We have worked with tissue and blood samples for 2 years. These were the same samples which were positive for myeloid leukemia, Mycoba...

Human T cell leukemia virus type I (HTLV-I) is a persistent virus that causes adult T cell leukemia and tropical spastic paraparesis/HTLV-I-associated myelopathy. Studies on rabbits have shown that viral proteins encoded by the open reading frames pX-I and pX-II are required for the establishment of the persistent infection. To examine the in vivo production of these proteins in humans, we have...

Skin diseases ranging from infective dermatitis to cutaneous lymphoma have been associated with human T cell leukemia virus (HTLV) type I. A generalized exfoliative papillated dermatopathy occurred in a rabbit 20 months into a course of chronic HTLV-I infection. Biopsies revealed epidermotropic T cell infiltrates, including Sezary-like cells, that resulted in a pattern mimicking cutaneous T cel...
