The research described in my thesis was performed at the Department of Medical Microbiology of the University Medical Center Groningen (UMCG), University of Groningen,

In the following, we provide a detailed overview of ECM proteins, present or absent in the interstitial matrix, i.e., parenchymal ECM, upon white matter

As IL-4-activated microglia, macrophages, and cytokine-activated astrocytes secreted significant proMMP7 levels, we next determined whether MMPs present in

Means to promote endogenous remyelination in multiple sclerosis (MS) benefit from insights into the role of inhibitory molecules that preclude remyelination. Fibronectin assembles

Indeed, as shown in figure 1 (white bars), when BMDMs were cultured on uncoated dishes, exposure to IFNγ+LPS induced the expression of the pro-inflammatory marker iNOS

We have demonstrated that TLR3 agonist poly(I:C) induced aggregation of fibronectin in demyelinated, but not myelinated OFSCs, and that remyelination was perturbed in

Thus, our findings demonstrate that aFn induces features of pro-inflammatory, classically activated and alternatively regenerative in macrophage in vitro (chapter 3
