Description
The brain and spinal cord are endowed with particular vascular systems, known as the blood-brain barrier (BBB) and blood-spinal cord barrier (BSCB) respectively, which maintain homeostasis between nervous parenchyma and peripheral circulation. Despite these common features, the BSCB presents structural and functional differences resulting in distinct vulnerability to pathological insults when compared to the BBB. Although, the heterogeneity of endothelial cell types underlies their remarkable ability to sub-specialize and provide specific requirements for a given vascular bed, very little is known concerning intrinsic differences between microvascular endothelial cells (MECs) derived from brain (BMECs) and spinal cord (SCMECs), including their response to inflammation. We used Agilent Whole Rattus Genome Microarray 4X44K to compare rat BMECs and SCMECs in both basal and inflammatory conditions; TNF-α-induced, TWEAK-induced and LPS-induced gene expression after 6 hr, 12 hr, 24 hr and 48 hr incubation.
