p 136: the role of blood brain barrier in multiple sclerosis
Authors
abstract
multiple sclerosis (ms) is an inflammatory disorder, in which neurons become demyelinated. to date, its etiology has remained unknown. nevertheless, certain features are inspected to provoke ms. for instance, improper function of immune cells is widely believed to be the basis of such disorder. in this concept, ms is stated as an autoimmune disease, which was asserted by major of studies, as cd8+ t-lymphocyte reacts to any agent containing major histocompatibility complex class 1 (mhc 1). they pass epithelium of brain capillaries to access locations where oligodendrocytes abnormally contain production of such gene. in this hypothesis, most articles assign peripheral immune system for disrupting the structure of blood brain barrier (bbb), which involves series of sequential mechanisms regulated by numerous genes of endothelium of bbb, as well as immune system. during last few decades other etiologies have been proposed, which are in intimate relationship with bbb. in 2015, a new pathway was discovered in which leukocytes might recruit and travel more easily in and out of the brain tissue. these newly discovered lymphatic vessels also might be in association with ms. the aim of this paper is to present the role of bbb in pathogenesis of ms. in conclusion, autoimmunity of ms is well asserted by most studies, which aimed to propose further etiological facts of ms. however, importance of each molecules and genes leading to its autoimmunity or disruption of bbb is yet to be more particularly determined.

Blood Brain Barrier (BBB) is a specialized non fenestrate barrier that formation by the endothelial cells and controls the transportation of the cells and molecules in to the brain. Reducing in function of BBB is one of disruptions in neurological diseases like multiple sclerosis. Endothelial progenitor cell (EPC) help to the BBB to control the diapedesis of inflammatory cells & molecules in to...

full textBlood-brain barrier disruption in multiple sclerosis.
The blood-brain barrier (BBB) is a complex organization of cerebral endothelial cells (CEC), pericytes and their basal lamina, which are surrounded and supported by astrocytes and perivascular macrophages. Collectively these cells separate and form the compartments of the cerebral vascular space and the cerebral interstitium under normal conditions. Without the BBB, the 'interior milieu' of the...

full textThe blood-brain barrier in cortical multiple sclerosis lesions.
The blood-brain barrier (BBB) is composed mainly of specialized endothelial cells characterized by the presence of intercellular tight junctions. Additionally, perivascular cells, astrocytes, and surrounding basement membranes determine BBB integrity. BBB disruption is an early phenomenon in the formation of new white matter multiple sclerosis (MS) lesions; however, knowledge of the extent of B...
