Researchers discover how leukaemia virus spreads through the body

Researchers have discovered the mechanism by which human T-lymphotropic virus type 1 (HTLV-1), the virus which causes adult T-cell leukaemia, spreads through the body. Previously it was not understood how HTLV-1 was able to spread between cells and pass between individuals, but according to research published today in Science, the virus spreads by subverting normal T-cell (a type of immune cell) behaviour, and without needing to release virus particles.
