  • We report the cases of 5 adolescents with human T lymphotropic virus type 1-associated myelopathy/tropical spastic paraparesis, acquired in all but 1 case from the mother. (oup.com)
  • In the present study we demonstrate that CD3+ T cells that bind tetramers of HLA-E and express its ligand, the NK-cell inhibitory receptor CD94/NKG2A, were significantly decreased in frequency in patients with human T-cell lymphotropic virus 1 (HTLV-1)-associated myelopathy/tropical spastic paraparesis (HAM/TSP) but not in asymptomatic HTLV-1 carriers.

  • This study will use three different magnetic resonance imaging (MRI) techniques to study HTLV-1 associated myelopathy/tropical spastic paraparesis (HAM/STP)-a disease of slowly progressive weakness in the legs. (clinicaltrials.gov)
  • Magnetic Resonance Imaging (MRI) has become an important tool in the diagnosis of inflammatory CNS diseases such as Multiple Sclerosis (MS) and HTLV-1 Associated Myelopathy/Tropical Spastic Paraparesis (HAM-TSP). (clinicaltrials.gov)
  • patients
  • The purpose of this study is to interview patients with these conditions and perform laboratory studies (specifically, HLA and other viral or genetic studies) to better understand these diseases and their relationship to the HTLV-1 virus and the family history and genetic factors that may be involved as well. (clinicaltrials.gov)
  • Importantly, HLA-E tetramer-positive or NKG2A+ T cells from HTLV-1 patients do not express Tax and display different TCR usage from the immunodominant Tax11-19-specific CD8+ T cells, suggesting that they do not encounter HTLV-1-infected cells. (www.gov.uk)
  • known
  • It is not known how the HTLV-1 virus causes this disease, but it is thought that as the body's immune system tries to destroy the virus, parts of the nervous system-primarily the spinal cord-are damaged. (clinicaltrials.gov)
  • levels
  • However, oligoclonally or monoclonally expanded levels of TCR Vwere more frequently detected within HTLV-1-infected individuals than healthy controls. (www.gov.uk)
  • transmission
  • Direct evidence for spread of HTLV-II has been documented only for transfusion (1, 2), but epidemiologic evidence supports its transmission sexually and via contaminated needles in drug users (3, 4). (annals.org)
