Susceptibility to multiple sclerosis (MS) has been consistently associated with the Human Leukocyte Antigen (HLA)-DRB11501 genotype, however effects on disease severity and clinical outcome have varied in different populations. We present the results of a high-resolution HLA-DRB1 genotyping and genotype-phenotype correlation study in a large West Australian MS cohort. Our findings indicate that in this population, which is of largely Anglo-Celtic and Northern European origin, HLA-DRB11501 is not only a strong determinant of disease risk but may also be associated with disease severity as measured by the Multiple Sclerosis Severity Score (MSSS), with the MSSS increasing by an estimated 0.51 per DRB11501 allele. We also found evidence that the HLA-DRB11201 allele is associated with less severe disease.

Background: Dural arteriovenous fistulas (DAVFs) pose a significant health threat owing to their high misdiagnosis rate. Case reports suggest that DAVFs or related acute events may follow medication use; however, drug-related risk factors remain unclear. In clinical practice, the concomitant use of multiple drugs for therapy is known as "polypharmacy situations," further increasing the risk of drug-induced DAVF.

Background Multiple sclerosis is a chronic, progressive, disabling disease associated with a high rate of infection, evidence of chronic inflammation, and a high mortality rate. Abnormalities of serum cytokines and changes in the activity of inflammatory cells were associated with relapsing-remitting multiple sclerosis (MS-RR). This study aims to introduce new inflammatory ratios derived from hematological and lipid indices as discriminators of T-helper (Th)-1/Th-2 activity in RR-MS.

The regeneration of myelin, or remyelination, occurs spontaneously following demyelination. The lysophosphatidylcholine (LPC)-induced focal demyelination model enables investigations into the mechanisms of remyelination, providing insight into the molecular basis underlying an evolving remyelinating microenvironment over a tractable time course.
View Article and Find Full Text PDFOligodendroglial lineage cells (OLCs) are critical for neuronal support functions, including myelination and remyelination. Emerging evidence reveals their active roles in neuroinflammation, particularly in conditions like Multiple Sclerosis (MS). This study explores the inflammatory translatome of OLCs during the early onset of experimental autoimmune encephalomyelitis (EAE), an established MS model.

Epidemiologic studies have linked EBV with certain cancers or autoimmune conditions, including multiple sclerosis (MS). Recent studies suggest that molecular mimicry between EBV proteins, particularly EBV nuclear antigen 1 (EBNA-1), and self-proteins is a plausible mechanism through which EBV infection may contribute to the development of autoimmune disorders.
