Vascular addressins control lymphocyte homing, thus regulating immunity and inflammation, but how addressin expression is patterned remains unknown. Here the authors identify composite DNA elements (NCCEs) that bind NKX2 homeodomain proteins cooperatively with COUP-TFII to define a morphogenetic code that targets transcription of mucosal vascular addressins.
