Objective(s): Human T cell leukaemia virus type 1 (HTLV-1) is associated with adult T cell leukaemia (ATL), a malignant lymphoproliferative disease that infects CD4 T cells. It is not clear why the majority of HTLV-1-infected individuals remain asymptomatic carries (ACs) and a minority develop ATL. Cellular immune response has a critical role in ATL and destroys malign...
Adult T-cell leukemia/lymphoma (ATL) is an aggressive T cell malignancy that occurs in HTLV-1 infected patients. Most ATL patients develop osteolytic lesions and hypercalcemia of malignancy, causing severe skeletal related complications and reduced overall survival. The HTLV-1 virus encodes 2 viral oncogenes, Tax and HBZ. Tax, a transcriptional activator, is critical to ATL development, and has...
Abstract Backgrounds Therefore, reports on the risk of HTLV-1-related diseases in organ transplantation have increased recent years, and management HTLV renal remains a challenge. Patients methods We retrospectively analyzed four HTLV-1-positive recipients or donors among 89 cases from 2006 to 2021. Results Among recipients, two patients developed adult T cell leukemia/lymphoma (ATL) derived at...
Adult T-cell leukemia/lymphoma (ATL), a human T-lymphotropic virus type 1 (HTLV-1)-associated disease, has a highly variable clinical course and four subtypes with therapeutic and prognostic implications. However, there are overlapping features between ATL subtypes and between ATL and nonmalignant (non-ATL) HTLV-1 infection complicating diagnosis and prognostication. To further refine the diagn...
We describe five patients with adult T-cell leukemia/lymphoma (ATL) with neither integration of human T-cell leukemia virus type I (HTLV-I) into their leukemia cells nor anti-HTLV-I antibody in their sera. These findings indicate that HTLV-I may not have been involved in leukemogenesis in these patients. The clinicohematological, cytopathological, and immunological features of HTLV-I-negative A...
Adult T-cell leukemia (ATL) is an aggressive T-cell malignancy caused by human T-cell leukemia virus type I (HTLV-1) infection and often occurs in HTLV-1-endemic areas, such as southwestern Japan, the Caribbean islands, Central and South America, Intertropical Africa, and Middle East. To date, many epidemiological studies have been conducted to investigate the incidence of ATL among general pop...
Adult T-cell lymphoma (ATL) is a hematological malignancy of CD4+ mature T-lymphocytes commonly associated with chronic human T-lymphotropic virus type I (HTLV-1) infection. Chronic HTLV-1 infection induces oncogenic mutations in T-cells, leading to an acute malignant transformation host cells. Atypically, ATL presents dermatological and pulmonary symptoms consistent “smoldering” disease patter...
OBJECTIVE(S) Human T Lymphocyte Virus Type one (HTLV-I) is a retrovirus that infects about 10-20 million people worldwide. Khorasan province in Iran is an endemic area. The majority of HTLV-I-infected individuals sustain healthy carriers but small proportion of infected population developed two progressive diseases: HAM/TSP and ATL. The proviral load could be a virological marker for disease mo...
Viral cell-free DNA (cfDNA) in plasma has been widely evaluated for detecting cancer and monitoring disease virus-associated tumors. We investigated whether the amount of cfDNA human T-cell leukemia virus type 1 (HTLV-1) correlates with state adult leukemia-lymphoma (ATL). HTLV-1 aggressive ATL was significantly higher than that indolent asymptomatic carriers. Notably, patients lymphoma represe...
Human T-cell leukemia virus (HTLV) is the etiologic agent of adult T-cell leukemia (ATL), a malignancy of T lymphocytes that is characterized by a long latency period after virus exposure. Intraperitoneal inoculation of severe combined immunodeficient (SCID) mice with HTLV-transformed cell lines and ATL tumor cells was employed to investigate the tumorigenic potential of HTLV type I (HTLV-I)-in...
