Absence of ERAP1 in B Cells Increases Susceptibility to Central Nervous System Autoimmunity, Alters B Cell Biology, and Mechanistically Explains Genetic Associations between ERAP1 and Multiple Sclerosis.

Abstract excerpt

Hundreds of genes have been linked to multiple sclerosis (MS); yet, the underlying mechanisms behind these associations have only been investigated in a fraction of cases. Endoplasmic reticulum aminopeptidase 1 (ERAP1) is an endoplasmic reticulum-localized aminopeptidase with important roles in trimming peptides destined for MHC class I and regulation of innate immune responses. As such, genetic polymorphisms in...
