RESUMO
O Brasil representa uma das áreas endêmicas para o vírus linfotrópico de células T humanas do tipo 1 (HTLV-1) e a cidade de Salvador, Bahia, possui a maior prevalência nacional da infecção por este retrovírus (1,8%), com cerca de 50.000 pessoas infectadas. O HTLV-1 foi o primeiro retrovírus humano descrito e está classicamente associado à leucemia/linfoma de células T do adulto (ATLL) e à mielopatia associada ao HTLV-1/paraparesia espástica tropical (HAM/TSP). A HAM/TSP é uma doença inflamatória do sistema nervoso central, cujos mecanismos imunopatogênicos não estão completamente elucidados. O papel dos linfócitos T citotóxicos na patogênese desta doença ainda não está bem definido. Neste estudo, foram avaliados o fenótipo e a função de linfócitos T citotóxicos de pacientes infectados pelo HTLV-1 com HAM/TSP...
ABSTRACT
Brazil represents one of the largest endemic areas for human T-lymphotropic virus cells type 1 (HTLV-1) infection and associated diseases. Salvador, Bahia, is considered as the Brazilian city with the highest national HTLV-1prevalence (around 1.8% in the general population). HTLV -1 was the first human retrovirus described and is classically associated with adult Tcell leukemia/lymphoma (ATLL) and HTLV-1 associated myelopathy/tropical spastic paraparesis (HAM/TSP). HAM/TSP is a chronic and progressive inflammatory disease of the central nervous system and your immunopathogenic mechanisms are not completely understood. The role of cytotoxic T-lymphocytes (CTLs) in the pathogenesis of this disease is still undefined. In this study we evaluated the phenotype and function of cytotoxic Tlymphocytes from HTLV-1-infected patients with HAM/TSP...
