eLife Assessment
In this important study, the authors develop a microfluidic "Vessel-on-Chip" model to study Neisseria meningitidis interactions in an in vitro vascular system. Compelling evidence demonstrates that endothelial cell-lined channels can be colonized by N. meningitidis, triggering neutrophil recruitment with advantages over complex surgical xenograft models. This system offers potential for follow-on studies of N. meningitidis pathogenesis, though it lacks the cellular complexity of true vasculature including smooth muscle cells and pericytes.
