Galectin-8 (Gal-8) is a member of a glycan-binding protein family that regulates the immune system, among other functions, and is a target of antibodies in autoimmune disorders. However, its role in multiple sclerosis (MS), an autoimmune inflammatory disease of the central nervous system (CNS), remains unknown. We study the consequences of Gal-8 silencing on lymphocyte subpopulations and the de...

Severe demyelinating disorders of the central nervous system (CNS) such as multiple sclerosis (MS), can be devastating for many young lives. To date, the factors resulting in poor remyelination and repair are not well understood, and reparative therapies that benefit MS patients have yet to be developed. We have previously shown that the activity and abundance of Lipoprotein Lipase (LPL)-the ra...

Nitric oxide has been implicated in the pathogenesis of multiple sclerosis. However, it is still unclear whether nitric oxide plays a protective role or is deleterious. We have previously shown that peroxynitrite, a reaction product of nitric oxide and superoxide, is toxic to mature oligodendrocytes (OLs). The toxicity is mediated by intracellular zinc release, phosphorylation of extracellular ...

Background Neuropathic pain represents the major public health burden with a strong impact on quality life in multiple sclerosis patients. Although some advances have been obtained in the last years, the conventional therapies remain poorly effective. Thus, the discovery of innovative approaches to improve the outcomes for multiple sclerosis patients is a goal of primary importance. With this a...

BACKGROUND Multiple sclerosis is a human autoimmunological disease that causes neurodegeneration. One of the potential ways to stop its development is induction of oral tolerance, whose effect lies in decreasing immune response to the fed antigen. It was shown in animal models that administration of specific epitopes of the three main myelin proteins - myelin oligodendrocyte glycoprotein (MOG),...

Activation of MAPK ERK1/2 has been shown to play an important role in Th1/Th2 polarization and in regulating cytokine production from APCs. The ERK family consists of two members ERK1 and ERK2, which share approximately 84% identity at the amino acid level and can compensate for each other for most functions. Despite these features, ERK1 and ERK2 do serve different functions, but there is very ...

OBJECTIVE Multiple sclerosis (MS) is the most common disabling neurological disease of young adults. The pathophysiological mechanism of MS remains largely unknown and no cure is available. Current clinical treatments for MS modulate the immune system, with the rationale that autoimmunity is at the core of MS pathophysiology. METHODS Experimental autoimmune encephalitis (EAE) was induced in m...

interleukin (il)-17-producing t helper (th)-17 cells have recently been explained as a distinct population  of  cd4+  t  cells which play an important  role in immunity against infectious agents. establishment of persistent phenotype of th17 cells and recognition of lineage-deviating factors are of most attractive goals in modern researches in immunology. although  il-6  and  tgf-β  are  freque...
