[The role of HTLV-1 provirus in clonal selection of the infected cells].

Abstract

HTLV-1 inserts its viral genome into the host cellular DNA in the form of a provirus. The proviral DNA is a key to understand the persistence and pathogenesis of HTLV-1 infection. There has been a significant progress in proviral research due to technological advances on DNA sequencing.Next generation sequencing technology revolutionized our understanding of the human genome,showing how it is organized and regulated, not only by the nucleotide sequence itself but also by epigenetic features and higher-order chromatin structure. We will review recent findings regarding the role of HTLV-1 provirus in HTLV-1 infection.
