HTLV-1 clonality in adult T-cell leukaemia and non-malignant HTLV-1 infection
Human T lymphotropic virus type 1 (HTLV-1) causes a range of chronic inflammatory diseases and an aggressive malignancy of T lymphocytes known as adult T-cell leukaemia/lymphoma (ATLL). A cardinal feature of HTLV-1 infection is the presence of expanded clones of HTLV-1-infected T cells, which may persist for decades. A high viral burden (proviral load) is associated with both the inflammatory a...
متن کاملAdult T-cell leukemia/lymphoma (ATLL)
Pathogenesis of the disease: ATLL is associated with HTLV-1 infection of the tumour clone in 100% of the cases. The interval between HTLV-1 infection and the onset of lymphoma is long (10-40 years) and only <5% of infected people actually develops the disease. HTLV-1 produces a trans-regulatory protein (Tax) inducing interleukin-2 (IL-2) and IL-2 receptor expression and consequent polyclonal CD...
متن کاملAdult T-cell leukaemia/lymphoma (ATLL) and T-cell leukemia virus type 1 (HTLV1)
Epidemiology The disease has a long latency, and affected individuals usually are exposed to the virus very early in life. The virus may be transmitted in breast milk, and through exposure to blood and blood products. The cumulative incidence of ATLL is estimated to be 2.5% among HTLV-1 carriers in Japan (1). Sporadic cases have been found in the United State and elsewhere. It occurs in adults ...
متن کاملHTLV-1 Tax and adult T-cell leukemia.
Human T-lymphotropic virus type I (HTLV-1) is the etiological agent of adult T-cell leukemia/lymphoma (ATL) and HTLV-1 associated myelopathy/tropical spastic paraparesis (HAM/TSP). HTLV-1 viral transactivator/oncoprotein, Tax, activates viral transcription and usurps regulatory mechanisms that are critical for cell growth and division to facilitate viral replication. The effects that Tax exerts...

We screened serum samples from patients with various hematological disorders and healthy individuals for the presence of adult T-cell leukemia/lymphoma associated antigen (anti-ATLA) antibodies. These antibodies were detected not only in all patients with ATL but frequently in those diagnosed as T-cell malignant lymphoma or T-cell chronic lymphocytic leukemia; the positivity rate of anti-ATLA a...
