Immune Privilege as an Intrinsic CNS Property: Astrocytes Protect the CNS against T-Cell-Mediated Neuroinflammation
Astrocytes have many functions in the central nervous system (CNS). They support differentiation and homeostasis of neurons and influence synaptic activity. They are responsible for formation of the blood-brain barrier (BBB) and make up the glia limitans. Here, we review their contribution to neuroimmune interactions and in particular to those induced by the invasion of activated T cells. We di...
متن کاملImmune privilege of the CNS is not the consequence of limited antigen sampling
Central nervous system (CNS) immune privilege is complex, and it is still not understood how CNS antigens are sampled by the peripheral immune system under steady state conditions. To compare antigen sampling from immune-privileged or nonprivileged tissues, we created transgenic mice with oligodendrocyte or gut epithelial cell expression of an EGFP-tagged fusion protein containing ovalbumin (OV...
متن کاملWhat is immune privilege (not)?
The 'immune privilege' of the central nervous system (CNS) is indispensable for damage limitation during inflammation in a sensitive organ with poor regenerative capacity. It is a longstanding notion which, over time, has acquired several misconceptions and a lack of precision in its definition. In this article, we address these issues and re-define CNS immune privilege in the light of recent d...
متن کاملThe multifaceted therapeutic potential of valproic acid beyond CNS axis
Valproic acid is widely used as an anti-epileptic globally. Anti-epileptic action is mediated by Gamma Amino Butyric Acid (GABA) receptors. In past and recently, several other clinical outcomes have been proposed by various studies. These under-reported clinical actions apart from anti-epileptic activity are mediated by various intracellular and extracellular pathways. Several mechanisms like H...
متن کاملImmune Privilege
T he concept of immune privilege refers to the observation that tissue grafts placed in certain anatomical sites, including the brain and eye, can survive for extended periods of time (1). Immune privilege is thought to reflect an evolutionary adaptation to protect vital structures from damage by inflammatory responses directed against pathogens. It was originally believed that antigens in immu...
