Intact and broad immune cell effector functions and specific individual cytokines have been linked to HIV disease outcome, but their relative contribution to HIV control remains unclear. We asked whether the proteome of secreted cytokines and signaling factors in peripheral blood can be used to discover specific pathways critical for host viral control. A custom glass-based microarray, able to ...
human t-cell lymphotropic virus type 1 (htlv-1) is associated with adult t-cell leukemia/lymphoma (atl) and htlv-1-associated myelopathy/tropical spastic paraparesis (ham/tsp). only a limited percentage of infected individuals develop disease in response to the virus while the majority remain asymptomatic and ham/tsp is the most common clinical manifestation of the virus. ham/tsp is an inflamma...
Human T-cell Lymphotropic Virus Type I (HTLV-I) primarily infects CD4+ helper T cells. HTLV-I infection is clinically linked to the development of Adult T-cell Leukemia/Lymphoma and of HTLV-I Associated Myelopathy/Tropical Spastic Paraparesis, among other illnesses. HTLV-I transmission can be either horizontal through cell-to-cell contact, or vertical through mitotic division of infected CD4+ T...
Interleukin 28B (IL28B) rs12979860 polymorphisms were examined in 41 individuals with human T-lymphotrophic virus type 1 (HTLV-1). The alleles CT/TT were more frequent in 12 individuals with HTLV-1-associated myelopathy/tropical spastic paraparesis than in 29 asymptomatic carriers (80% vs 20%; P = .03), and median HTLV-1 proviral load was greater in CT/TT than CC carriers (P = .01). Thus, IL28B...
Objectives: This paper reports for the first time three cases of infection by HTLV-I via organ transplantation; all the organs coming from the same asymptomatic infected donor. The need is considered for the implementation of compulsory screenings for HTLV antibodies on organ donors and on blood banks. Methods: The determination of antibodies for HTLV-I/II on samples of serum and cerebral spina...

OBJECTIVE(S) HTLV-I and HIV virus quantification is an important marker for assessment of virus activities. Since there is a direct relationship between the number of virus and disease progression, HTLV-I and HIV co-infection might have an influence on the development of viral associated diseases, thus, viral replication of these viruses and co-infection were evaluated. MATERIALS AND METHODS ...
HTLV-1 was the first human oncogenic retrovirus to be discovered. It is the etiological agent of adult T leukemia/lymphoma (ATLL) and of tropical spastic paraparesis/HTLV-1 associated myelopathy (TSP/HAM), two diseases that develop after a long latency period. Importantly, HTLV-1 does not cause ATLL through insertional mutagenesis. Apart from the gag, pro, pol and env genes, which are common to...
Despite abundant activated virus-specific cytotoxic T lymphocytes (CTLs), patients with human T-lymphotropic virus type 1 (HTLV-1)-associated myelopathy/tropical spastic paraparesis (HAM/TSP) showed a significantly higher frequency of infected T cells than did healthy virus carriers (HVCs). Here, we demonstrate that at a given proviral load, the frequency of CD8(+) T cells that are negative for...
