Neuroimmunology: Basement membrane laminins guard the CNS

Kirsty Minton

The extravasation of myelin-specific CD4+ T cells from the blood into the central nervous system (CNS) is a crucial factor in the pathogenesis of multiple sclerosis. We know much about how leukocytes traverse the endothelial cell monolayer of post-capillary venules, but far less is known about how they cross the underlying basement membrane, which is the rate-limiting step in transmigration.
