Abstract

Human T cell leukemia virus type 1 (HTLV-1) is an etiological pathogen of several human diseases, including adult T-cell leukemia (ATL), HTLV-1-associated myelopathy (HAM)/tropical spastic paraparesis (TSP), and inflammatory disorders such as uveitis and dermatitis. HTLV-1 spreads mainly through cell-to-cell transmission, induces clonal proliferation of infected T cells in vivo, and after a long latent period, a subset of HTLV-1 carriers develop ATL. Understanding the molecular mechanisms of infection and oncogenesis is important for the development of new strategies of prophylaxis and molecular-targeted therapies, since ATL has a poor prognosis, despite intensive chemotherapy. In this review, we will summarize recent progress in HTLV-1 research, and especially novel findings on viral transmission and leukemogenic mechanisms by two viral oncogenes, HBZ and tax.

Keynote webinar | Spotlight on antibody–drug conjugates in cancer

Antibody–drug conjugates (ADCs) are novel agents that have shown promise across multiple tumor types. Explore the current landscape of ADCs in breast and lung cancer with our experts, and gain insights into the mechanism of action, key clinical trials data, existing challenges, and future directions.
