In this study further understanding of the mechanisms of BBB disruption was explored in blood vessels located in leptomeninges (pial vessels) and brain parenchyma (parenchymal vessels) by examining the expression of junctional complex proteins in murine brain infected with Mesocestoides corti.
For instance, in adult murine brain neurons, with both PSEN isoforms genetically ablated, such defects occur very early (already at 2 3 months after birth) [ 69].
Total RNA was isolated from murine brain homogenates with the Nucleospin® RNA II Purification kit (Clontech Laboratories, Mountain View, CA, USA; Bioke, Leiden, the Netherlands).
Finally, and most importantly for the present study, the presence of melanocytes was also verified in murine brain arteries, with a particularly high concentration of melanocytes observed in the wall of middle cerebral arteries and in several of their branches on the basal brain surface.
We demonstrate that the d-peptides' concentrations in murine brain directly correlate with concentrations in cerebrospinal fluid.
To enable prokaryotic expression of His-tagged L1ICD, including the amino acids Cys-Phe-Ile (CFI) of the transmembrane domain, the following steps were performed: RNA from murine brain was extracted with TRIzol according to the manufacturer's manual (Invitrogen, Karlsruhe, Germany).
Cyclin E expression is maintained at a high level in the adult murine brain, in contrast with other organs, and the authors of that study found that virtually all cyclin E is complexed to CDK5 to form a catalytically inactive complex.
The relative enrichment of GSK3β in LRRK2 murine brain immunoprecipitates in comparison with GSK3α, a protein not considered to play a major role in Wnt signaling, and the failure to co-immunoprecipitate cytosolic Rab5b, confirmed the specificity of these assays.
C1q expression in the murine brain is known to increase with age (Reichwald et al., 2009).
In vitro transfection of murine brain capillary endothelial bEnd.3 cells with pSPE, pTETA, and pLPEI polyplexes was 2.3 4.9 times more effective compared with the non-degradable LPEI 22 kDa reagent (ExGen500) in the presence of serum.
