T cell priming by dendritic cells (DC) from gut-associated lymphoid tissues gives rise to
effector cells with pronounced gut tropism. The mechanism for DC-dependent imprinting of
gut specificity has remained unknown. New findings point to retinoic acid, which is uniquely
produced by intestinal DC, but not by DC from other lymphoid organs (Iwata et al., 2004; this
issue of Immunity).
