Adult T-cell leukemia-lymphoma (ATL) is an uncommon highly aggressive T-cell lymphoma associated with human T-cell lymphotropic virus type 1 (HTLV-1) infection. It is rarely encountered during pregnancy and is particularly challenging to treat due to its aggressive nature and because of the lack of robust data on optimal chemotherapy. We report a case of a Jamaican immigrant diagnosed with ATL ...

This review focuses on current approaches to understanding the immunopathogenesis of human T cell lymphotropic virus (HTLV) type I-associated myelopathy/tropical spastic paraparesis (HAM/TSP) based on newly developed molecular and immunologic techniques that have been adapted to studies of HTLV-I proviral load, HTLV-I mRNA, and HTLV-I tax-specific CD8 T cells. These methods enable researchers t...

See page 932 Emerging zoonotic diseases are among the most important public-health threats facing humanity. One of the major examples is the AIDS epidemic which emerged in the 1980s as a result of cross-species transmissions of simian immunodeficiency viruses (SIVs) to human beings several decades earlier. As with HIV, other retroviruses (such as human T-lymphotropic viruses 1 and 2) are also o...

Killer cell immunoglobulin-like receptors (KIRs) influence both innate and adaptive immunity. But while the role of KIRs in NK-mediated innate immunity is well-documented, the impact of KIRs on the T cell response in human disease is not known. Here we test the hypothesis that an individual's KIR genotype affects the efficiency of their HLA class I-mediated antiviral immune response and the out...
