Editor's Notes
- Menurut National Multiple Sclerosis Society, kira-kira 400,000 orang Amerika tercatat menderita MS, dan pada setiap minggunya sekitar 200 orang didiagnosis MS. Di seluruh dunia, MS mungkin diderita 2.5 juta individu. Umumnya serangan terjadi dalam dekade ketiga dan keempat, walaupun penyakit ini bisa mulai dalam masa kanak-kanak dan juga di atas usia 60 tahun. Secara keseluruhan, MS terjadi lebih sering pada wanita dibandingkan laki-laki, dengan perbandingan adalah kira-kira 2:1
- HLA DRB1 terdapat 50 spesifitas genom
- Human Leukosit antigen kompleks yang memiliki fungsi biologis HLA sama dengan MHC, memproses dan mempresentasikan antigen eksogen e.g virus, bakteri
- Natalizumab blocks the attachment of lymphocytes to vascular cell adhesion molecule (VCAM) in inflamed blood vessels. Interferon-(IFNb) blocks metalloproteinases 2 and 9, which impairs diapedesis. The inducible expression of class II molecules of the major histocompatibility complex is blocked by statins. Glatiramer actetate and altered peptide ligands (APL) interfere with T-cell recognition of myelin in the induced major histocompatibility complex (MHC) class II molecules. T-cell recognition of myelin leads to production of osteopontin (OPN) and interleukin 23 (IL-23), which have a pathogenic role in autoimmune demyelination. B cells are also blocked from entering the central nervous system by natalizumab. When they do gain entry they interact with complement to injure the myelin sheath. Tolerization of B cells can be accomplished with DNA vaccines.
