14 | Remodelling of the microvasculature by perivascular macrophages after stroke

Acute stroke alters the expression of genes in the neurovascular unit. In this project will investigate how perivascular macrophages affect endothelial gene expression. We will focus on genes that have potential for affecting endothelial-basement membrane interactions. Their function will be investigated with viral vectors, a transgenic strategy and by a proteomics approach.
