Background: HTLV-1 (Human T_cell lymphotropic virus type), with about 20 million individuals infected worldwide, is a global health problem and is endemic in certain area such as Japan and Khorasan province of Iran. HTLV-1 is the causative agent of progressive diseases, Adult T cell Leukemia (ATL), and HTLV-I Associated Myelopathy/Tropical Spastic Paraparesis (HAM/TSP) which have no ...
The host immune response is believed to tightly control viral replication of deltaretroviruses such as human T-lymphotropic virus type 1 (HTLV-1) and bovine leukemia virus (BLV). However, this assumption has not been definitely proven in vivo. In order to further evaluate the importance of the immune response in the BLV model, we studied the fate of cells in which viral expression was transient...
A third type of primate T-lymphotropic virus, PTLV-L, with STLV-PH969 as a prototype, has recently been isolated from an African baboon (Papio hamadryas). Classification of this virus has been based on partial sequence analysis of cDNA from a virus-producing cell line, PH969. We obtained the complete nucleotide sequence of this virus with a proviral genome of 8,916 bp. All major genes, homologo...
To better understand the origins and modes of transmission of HTLV-3 and to search for other retroviral infections (HTLV-1, HTLV-2, foamy viruses), we studied the family of a HTLV-3-infected individual (Pyl43), from Cameroon. Thirty-five persons were included. All adult men were still actively hunting nonhuman primates (NHP). All women were also butchering and cutting-up animals. Five persons r...
Adult T-cell leukemia/lymphoma (ATLL), a T-cell neoplasm caused by human T-cell lymphotropic virus type 1 (HTLV-1), develops in the majority of cases in individuals who were infected with HTLV-1 as young children, by their mother during prolonged breastfeeding. We report the case of a Caucasian French man, whose parents were HTLV-1-seronegative and who developed ATLL after HTLV-1 sexual transmi...
