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...

Little is known about the transmission or tropism of the newly discovered human retrovirus, human T-cell lymphotropic virus type 3 (HTLV-3). Here, we examine the entry requirements of HTLV-3 using independently expressed Env proteins. We observed that HTLV-3 surface glycoprotein (SU) binds efficiently to both activated CD4(+) and CD8(+) T cells. This contrasts with both HTLV-1 SU, which primari...

Human T-cell lymphotropic virus type 1 , 2 (HTLV-1, 2) is endemic in Particular Areas of the world in which it is associated with myeloid leukemia.In this study, we described the prevalence of HTLV-1, 2 in myeloid leukemia and Mycobacterium Tuberculosis in Iran. We have worked with tissue and blood samples for 2 years. These were the same samples which were positive for myeloid leukemia, Mycoba...
