Methodology to detect and study de novo human T-cell leukemia virus (HTLV)-1 infection is
required to further our knowledge of the viruses’ mechanisms of infection and to study
potential therapeutic interventions. Whilst methodology currently exists, utilisation of an anti-
Tax antibody to detect de novo Tax expression in permissive cells labelled with cell tracker
allowing for the detection by flow cytometry of new infection after co-culture with donor cell
lines productively infected with HTLV-1 is an alternative strategy. Using this methodology,
we have been able to detect de novo infection of the T cell line HUT78 following co-culture
with the productively infected HTLV-1 donor cell line MT-2 and to confirm that infection
can be effectively blocked with well characterised infection inhibitors. This methodology will
benefit experimental studies examining HTLV infection in vitro and may aid identification of
therapeutic agents that block this process.
