“…ATLL is a mature CD41 lymphoid malignancy that occurs in 5-10% of individuals infected by HTLV-1 by breast feeding [7]. It occurs in four different subtypes, smoldering, chronic, leukemic, or lymphomatous disease [8].…”

Effect of treatment of Strongyloides infection on HTLV‐1 expression in a patient with adult T‐cell leukemia

et al. 2007

Human T-cell leukemia virus type 1 (HTLV-1) is associated with adult T-cell leukemia-lymphoma (ATLL) in about 5% of infected individuals. Coinfection by Strongyloides stercoralis has been suggested to be a cofactor for development of ATLL. We describe a patient who presented with HTLV-1-associated chronic ATLL and Strongyloides infection. Studies of this patient's viral RNA levels demonstrated stimulation of HTLV-1 replication by Strongyloides, which resolved with anti-helminthic therapy. This case provides support for the hypothesis that Strongyloides is a cofactor for ATLL via T-cell stimulation. Am. J. Hematol. 82:929-931, 2007. V

“…Human T-cell leukemia virus type 1 (HTLV-1) is a single-stranded RNA retrovirus that infects 20 million people worldwide (Proietti et al, 2005) (Table 1). It was discovered in 1980 (Poiesz et al, 1980), and was associated with adult T-cell leukemia (ATL) shortly thereafter (Hinuma et al, 1981).…”

Viruses are associated with 15-20% of human cancers worldwide. In the last century, many studies were directed towards elucidating the molecular mechanisms and genetic alterations by which viruses cause cancer. The importance of epigenetics in the regulation of gene expression has prompted the investigation of virus and host interactions not only at the genetic level but also at the epigenetic level. In this study, we summarize the published epigenetic information relating to the genomes of viruses directly or indirectly associated with the establishment of tumorigenic processes. We also review aspects such as viral replication and latency associated with epigenetic changes and summarize what is known about epigenetic alterations in host genomes and the implications of these for the tumoral process. The advances made in characterizing epigenetic features in cancer-causing viruses have improved our understanding of their functional mechanisms. Knowledge of the epigenetic changes that occur in the genome of these viruses should provide us with markers for following cancer progression, as well as new tools for cancer therapy.

“…3 An estimated 10--20 million people worldwide are infected with HTLV-1, and HTLV-1 is endemic in southwestern Japan, the island of Kyushu, Africa, the Caribbean Islands and South America. 4 ATLL cells are mainly derived from activated helper T cells with the CD3 þ , CD4 þ , CD8 À and CD25 þ (also known as interleukin 2 receptor alpha (IL-2Ra)) cell surface markers. 2 A fraction of ATLL cases have been shown to also express forkhead box P3 (FOXP3), which is a master gene for regulatory T cells (T-reg), suggesting that some cases of ATLL may originate from HTLV-1-infected T-reg cells.…”

Clinical significance of CADM1/TSLC1/IgSF4 expression in adult T-cell leukemia/lymphoma

Cell adhesion molecule 1 (CADM1/TSLC1) was recently identified as a novel cell surface marker for adult T-cell leukemia/ lymphoma (ATLL). In this study, we developed various antibodies as diagnostic tools to identify CADM1-positive ATLL leukemia cells. In flow cytometric analysis, the percentages of CD4 þ CADM1 þ double-positive cells correlated well with both the percentages of CD4 þ CD25 þ cells and with abnormal lymphocytes in the peripheral blood of patients with various types of ATLL. Moreover, the degree of CD4 þ CADM1 þ cells over 1% significantly correlated with the copy number of the human T-lymphotropic virus type 1 (HTLV-1) provirus in the peripheral blood of HTLV-1 carriers and ATLL patients. We also identified a soluble form of CADM1 in the peripheral blood of ATLL patients, and the expression levels of this form were correlated with the levels of soluble interleukin 2 receptor alpha. Moreover, lymphomas derived from ATLL were strongly and specifically stained with a CADM1 antibody. Thus, detection of CD4 þ CADM1 þ cells in the peripheral blood, measurement of serum levels of soluble CADM1 and immunohistochemical detection of CADM1 in lymphomas would be a useful set of markers for disease progression in ATLL and may aid in both the early diagnosis and measurement of treatment efficacy for ATLL.
