HTLV-1-induced leukotriene B4 secretion by T cells promotes T cell recruitment and virus propagation

Abstract

HTLV-1 predominantly spreads through direct cell-cell contacts, but mechanisms of target cell recruitment are unclear. Here, the authors show that HTLV-1 infected T-cells secrete leukotriene B4, which recruits T-cells, facilitates HTLV-1 transmissionin vitro, and increases the number of infected clones in mice.
