Defective human T-lymphotrophic virus type I provirus in T-cell prolymphocytic leukaemia

Two types of defective human T-lymphotropic virus type I provirus in adult T-cell leukemia.

Adult T-cell leukemia (ATL), an aggressive neoplasm of mature helper T cells, is etiologically linked with human T lymphotropic virus type I (HTLV-1). After infection, HTLV-I randomly integrates its provirus into chromosomal DNA. Since ATL is the clonal proliferation of HTLV-I-infected T lymphocytes, molecular methods facilitate the detection of clonal integration of HTLV-I provirus in ATL cell...

Study of the Association Between Human T-cell Lymphotropic Virus Type I Infection and Lichen Planus

Human T Lymphotropic Virus Type I (HTLV-I) Oncogenesis: Molecular Aspects of Virus and Host Interactions in Pathogenesis of Adult T cell Leukemia/Lymphoma (ATL)

    The study of tumor viruses paves the way for understanding the mechanisms of virus pathogenesis, including those involved in establishing infection and dissemination in the host tumor affecting immune-compromised patients. The processes ranging from viral infection to progressing malignancy are slow and usually insufficient for establishment of transformed cells that develop cancer in only ...

T-Cell Prolymphocytic Leukaemia: A Case Series

T-prolymphocytic leukaemia (T-PLL) is a rare mature T-cell lymphoproliferative disorder. It is seen more often in middle-aged and elderly individuals with a median age of onset of 65 years and a male predominance of 2:1. Patients present with hepatosplenomegaly, lymphadenopathy, 15% may have serous effusions and approximately 20% have skin involvement. The white cell count is often above 200 x ...
