ECM: Chemoattraction but not adhesion

Abstract

Themechanisms that regulate 3-dimensional (3D) neutrophil chemotaxis are poorly understood. In this issue of Blood, Afonso et al demonstrate that the collagen receptor Discoidin domain receptor 2 (DDR2) promotes neutrophil chemotaxis in 3D by triggering matrix metalloproteinase (MMP) activity and the generation of chemotactic collagen peptides.
