T Lymphocyte Adhesion to Human Brain

Intracellular domain of brain endothelial intercellular adhesion molecule-1 is essential for T lymphocyte-mediated signaling and migration.

To examine the role of the ICAM-1 C-terminal domain in transendothelial T lymphocyte migration and ICAM-1-mediated signal transduction, mutant human (h)ICAM-1 molecules were expressed in rat brain microvascular endothelial cells. The expression of wild-type hICAM-1 resulted in a significant increase over basal levels in both adhesion and transendothelial migration of T lymphocytes. Endothelial ...

P27: KCNK2 and Adhesion Molecules in an in-Vitro Blood Brain Barrier Model

Two-pore domain potassium channels, like KCNK2, are known to play an important role in inflammatory diseases such as multiple sclerosis (MS). Upregulation of cellular adhesion molecules in mouse brain microvascular endothelial cells (MBMECs) of Kcnk2-/- mice resulted in elevated leukocyte trafficking into the central nervous system under inflammatory conditions. The current project aims to gain...

T Lymphocyte Adhesion to Human Brain Pericytes

T lymphocyte adhesion to human brain pericytes is mediated via very late antigen-4/vascular cell adhesion molecule-1 interactions.

T cell adhesion to the brain microvascular endothelium and subsequent migration into the brain parenchyma is one of the major events in the development of multiple sclerosis (MS). Interactions of the T cell integrin very late antigen-4 (VLA-4) with its receptor, vascular cell adhesion molecule-1 (VCAM-1) have been described to be of crucial importance for the development of MS. We investigated ...
