The DNA sequences of genomes from G + C-rich and A + T-rich lymphotropic herpesviruses [i.e. gammaherpesviruses; Epstein-Barr virus and herpesvirus saimiri (HVS)] are deficient in CpG dinucleotides and contain an excess of TpG and CpA dinucleotides relative to frequencies predicted from their mononucleotide compositions. In contrast, for sequences from genomes of G + C-rich and A + T-rich neuro...

Three licensed and three research human T-cell lymphotropic virus type I (HTLV-I) enzyme immunoassay (EIA) kits were evaluated with a panel of 213 serum or plasma samples which were previously tested by the indirect immunofluorescence method for HTLV-I and -II antibodies. The three research kits were found to be more sensitive and specific than the three licensed kits.

BACKGROUND We previously suggested that infection with the human T-lymphotropic virus type 1 (HTLV-1) subtype C is associated with bronchiectasis among Indigenous Australians. Bronchiectasis might therefore result from an HTLV-1-mediated inflammatory process that is typically associated with a high HTLV-1 proviral load (PVL). Human T-lymphotropic virus type 1 PVL have not been reported for Indi...

The lifelong infection with the human T lymphotropic virus type 1 (HTLV-1) has been associated a variety of clinical manifestations; one less-explored is HTLV-1-associated pulmonary disease. Imaging lung damage caused by HTLV-1 hyperinflammatory cascade can be similar to sequelae from TB infection. Our study aims describe lesions HTLV-1-positive patients without past or current active and evalu...

Human T-lymphotropic viruses type 1 (HTLV-1) and type 2 (HTLV-2) present very similar genomic structures but HTLV-1 is more pathogenic than HTLV-2. Is this difference due to their transactivating Tax proteins, Tax-1 and Tax-2, which are responsible for viral and cellular gene activation? Do Tax-1 and Tax-2 differ in their cellular localization and in their interaction pattern with cellular fact...
