Transmitted Drug Resistance Among Recently Diagnosed Adults and Children in São Paulo, Brazil.

abstract：:The human T cell leukemia virus type 1 (HTLV-1) is the etiologic agent of adult T cell leukemia (ATL), an aggressive and fatal leukemia of CD4(+) T lymphocytes, and is also associated with a neurological demyelinating disease, tropical spastic paraparesis. The oncogenic potential of HTLV-1 resides in the 353-aa, 40-kD...

abstract：:Dendritic cells (DCs) have been shown to be important in the replication of human and simian immunodeficiency viruses (HIV and SIV, respectively) in vivo and in vitro. DCs express CD4 and several chemokine receptors, such as CCR5 and CXCR4, which are important for viral entry. In vivo, DCs are abundant at body surface...
