Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the human central nervous system. NO, ion channel, cytokine and testosterone play an important role in MS, and may be associated with the pathogenesis of ED. Meanwhile, the relationship between MS-induced peripheral nerve injury and ED should be understood correctly. Further researches on these mediators can provide some theoretical evidence for the clinical treatment of ED.

This review attempts to define the relationship between IL-15 and autoimmune disease (AID) from IL-15's tissue distribution, expression regulation and biologic function. Meanwhile, five IL-15 dysregulation-related AIDs and four IL-15/IL-15R-targeted AID therapies are described.

Mast cell which is considered to participate in immune response has long been studied. However its true role in center nervous system is still unknown. Recently,mast cell has been found to play an important function during the process of multiple sclerosis and Wernicke's encephalopathy in the brain. Multiple sclerosis is an inflammatory demyelinating disease, and Wernicke's encephalopathy is caused by deficiency of thiamine. Mast cell deteriorates the neuronal damage and the course of diseases by their mediators. Such studies may supply new idea on the therapy of these diseases.

Multiple sclerosis (MS) is an autoimmune disease. The etiology and pathogenesis of MS remain unclear. At present, there are substantial evidences to support the hypothesis that genetics plays a crucial role. The people who have genetic predisposing genes easily develop immune-mediated disorder, probably in conjunction with environmental factors. The aim of this review is to describe recent observations regarding the immunologic pathogenesis of MS.

The primary chemical components of Astragalus membranaceus include polysaccharides, saponins, flavonoids, and amino acids. Recent studies have shown that Astragalus membranaceus has multiple functions, including improving immune function and exerting antioxidative, anti-radiation, anti-tumor, antibacterial, antiviral, and hormone-like effects. Astragalus membranaceus and its extracts are widely used in clinical practice because they have obvious therapeutic effects against various autoimmune diseases and relatively less adverse reaction. Multiple sclerosis (MS) is an autoimmune disease of central nervous system (CNS), which mainly caused by immune disorder that leads to inflammatory demyelination, inflammatory cell infiltration, and axonal degeneration in the CNS. In this review, the authors analyzed the clinical manifestations of MS and experimental autoimmune encephalomyelitis (EAE) and focused on the efficacy of Astragalus membranaceus and its chemical components in the treatment of MS/EAE.

To understand the function of Mayven and investigate the pathogenesis of multiple sclerosis, the gene sequences of different truncated Mayven were amplified from the gene library of human brain. These truncated fragments, including fragment P1 (1-902 bp), fragment P2 (1-523 bp), fragment P3 (507-182 bp) and fragment P4 (887-1782 bp), were cloned into pGEX-4T-2 vector to construct recombinant plasmids. The recombinant plasmids were transformed into E. coli BL21(DE3) and induced to express by IPTG. The expressed proteins were detected by SDS-PAGE and Western blot, and were purified by GST purifying system. The results showed that recombinant express vectors of different truncated GST-Mayven were successfully constructed and were expressed in soluble form protein induced by IPTG. The fusion proteins have good reactivity to GST antibody. The construction of recombinant express vectors of different truncated GST-Mayven lays a basis for further function study on Mayven.

Multiple sclerosis (MS) and experimental autoimmune encephalomyelitis (EAE), a pathologically similar disease used to model MS in rodents, are typical CD4+ T cell-dominated autoimmune diseases. CD4+ interleukin (IL)17+ T cells (Th17 cells) have been well studied and have shown that they play a critical role in the pathogenesis of MS/EAE. However, studies have suggested that CD8+IL17+ T cells (Tc17 cells) have a similar phenotype and cytokine and transcription factor profiles to those of Th17 cells and have been found to be crucial in the pathogenesis of autoimmune diseases, including MS/EAE, psoriasis, type I diabetes, rheumatoid arthritis, and systemic lupus erythematosus. However, the evidence for this is indirect and insufficient. Therefore, we searched for related publications and attempted to summarize the current knowledge on the role of Tc17 cells in the pathogenesis of MS/EAE, as well as in the pathogenesis of other autoimmune diseases, and to find out whether Tc17 cells or Th17 cells play a more critical role in autoimmune disease, especially in MS and EAE pathogenesis, or whether the interaction between these two cell types plays a critical role in the development of the disease.
