MEOX2 and Alzheimer disease: Recent genomic profiling of brain endothelial cells shows low levels of vascular-restricted mesenchyme homeobox 2 gene (MEOX2) in AD individuals lead to aberrant angiogenesis and premature pruning of capillary networks resulting in reductions in the cerebral microcirculation and that hypoxia suppresses MEOX2 expression in brain endothelial cells [119].
