Short-circuiting autoimmune disease by target-tissue-derived nitric oxide

Abstract

A previous report from this laboratory suggested that expression of skeletal-muscle-derived, inducible nitric oxide synthase (iNOS), is associated with resistance to the autoimmune model of myasthenia gravis (MG) demonstrated by Wistar Furth rats following the passive transfer of antibody reactive with the nicotinic acetylcholine receptor (AChR). The study reported below demonstrates an association between increased expression of iNOS/NO in Wistar Furth rats and the induction of programmed cell death (apoptosis) in both macrophages and CD4+ T cells that attempt to traffic through targeted muscles. It is concluded that production of muscle-derived NO is protective in experimental MG, and in part, dictates the severity of eventual immunopathology.

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
