Topic: Immune Mediated encephalomyelitis


  
  Immune-Mediated Tissue Injury
The prototypic immune complex disease is serum sickness (e.g., a patient injected with a heterologous antiserum, such as horse serum).
This type of lesion may be secondary to a drug (e.g., penicillin), to the presence of a foreign protein antigen in the circulation (e.g., a viral protein), or rarely, to the release of an antigen by tumor cells.
The immune response to Mycobacterium leprae varies widely, from the "tuberculoid" leprosy pattern with potent DTH, granulomas, and low numbers of organisms in tissues, to the "lepromatous" pattern with weak or suppressed DTH and numerous organisms.

 (abstract) - IMMUNE-MEDIATED BRAIN INJURY AND REPAIR: MECHANISMS AND THERAPIES
Analysis of MS lesions showed increases in cell-death-related proteins such as the anti-apoptotic protein Bcl-2, increases in DNA oxidation, and electrophoresed DNA produced a "ladder" characteristic of apoptotic DNA cleavage.
Furthermore, it was found that CSF from patients with aggressive MS contained soluble mediators that induce axonal damage and apoptosis of neurons in culture.
In experimental autoimmune encephalomyelitis (EAE) model, immunocytochemical identification of glial cells revealed that substantial numbers of cells were dying by apoptotic mechanisms rather than by cell necrosis.

Mechanisms that are operative in transendothelial migration of T cells and monocytes have been elaborated in vitro and in animal models of MS.
In addition to AM, chemokines have been demonstrated to be crucial for T cell recruitment into the CNS during inflammation.The important functional role of these molecules in the pathogenesis has been elucidated in treatment studies in EAE.
The clinical value of this treatment approach that aims at inhibiting transendolthelial migration of immune cells in MS is currently under investigation.

Viral infections of the central nervous system and immune responses to these infections cause a variety of neurological diseases.
Infection with a neuroadapted strain of Sindbis virus (NSV) causes fatal encephalomyelitis, but passive transfer of immune serum after infection protects from fatal disease and infectious virus is cleared.
To determine whether persistent NSV RNA is associated with neurological damage, we examined the brains of recovered mice and found progressive loss of the hippocampal gyrus, adjacent white matter, and deep cerebral cortex associated with mononuclear cell infiltration.

 CD152-mediated T-cell migration in experimental Autoimmune Encephalomyelitis   (Site not responding. Last check: 2007-10-25)
The immune response is directed against components of the myelin sheet leading to chronic inflammation and, ultimately, to demyelination and gliosis.
So far, the recruitment of autoreactive, inflammatory as well as antiinflammatory T-cells into the brain is not fully understood.
Besides learning how CD152 mediates the transendothelial migration of T-cells into the CNS, we will gain knowledge how CD152 influences the composition of protective and neuroinflammatory cells at the site of inflammation in the brain.

 NIH Guide: THE ROLE OF MICROGLIA IN NORMAL AND ABNORMAL IMMUNE RESPONSES OF THE NERVOUS SYSTEM
This PA The Role of Microglia in Normal and Abnormal Immune Responses of the Nervous System, is related to autoimmunity response of the CNS which are vital to multiple sclerosis and immune-mediated encephalomyelitis.
If so, they may be equally important in initiating and sustaining immune responses to CNS elements such as myelin, oligodendroglia and neoplastic astrocytes.
Activation of microglia, so that they express Class II and other phenotypic markers, may be related to the presence of activated T cells arriving from the periphery.

 LIF receptor signaling limits immune-mediated demyelination by enhancing oligodendrocyte survival - Nature Medicine
An alternative approach would be to inhibit mechanisms that drive the neuropathology of MS, which often includes the death of oligodendrocytes, the cells responsible for myelinating the CNS.
Identification of molecular mechanisms that mediate the stress response of oligodendrocytes to optimize their survival would serve this need.
We also demonstrate that this therapeutic effect complements endogenous LIF receptor signaling, which already serves to limit oligodendrocyte loss during immune attack.

Borna disease virus (BDV) infection represents an excellent model system to study immunopathological mechanisms based on a T cell-mediated immune reaction in the central nervous system.
After experimental infection BDV causes a persistent infection of the central nervous system and induces Borna disease, an immune-mediated encephalomyelitis.

Acute Disseminated Encephalomyelitis is a "demylinating" disorder (analogous to losing the insulation around nerves) that may occur following a viral infection, rabies vaccine, or without a known preceding cause.
Multiple sclerosis is also a "demylinating disorder" and is thought to be caused by an immune-mediated process.

The presence of oligoclonal bands, a substantial pleocytosis, or PMNs or red cells in the CSF should suggest such possibilities as acute multiple sclerosis, acute hemorrhagic leukoencephalitis, HIV-associated leukoencephalomyelopathy, multifocal VZV leukoencephalitis, or postinfectious or vaccinal immune-mediated encephalomyelitis.
Prior to the HIV epidemic, common associated diseases included lymphoproliferative disorders, immune deficiency states, myeloproliferative disease, and chronic infectious or granulomatous diseases.
Since 1984, the importance of these associated disorders has been dwarfed by that of AIDS.
