See “α-enolase autoantibodies cross-reactive to viral proteins in a mouse model of biliary atresia,” by Lu BR, Brindley SM, Tucker RM, et al, on page 1753. Biliary atresia (BA), a condition unique to infancy, is the end result of a destructive, idiopathic, inflammatory process affecting both intra- and extrahepatic bile ducts, leading to fibrosis and obliteration of the biliary tract and ultimately to biliary cirrhosis. It is the most serious and most frequent surgically correctable liver disorder in infancy, as well as the most prevalent indication for liver transplantation in children.1Mieli-Vergani G. Vergani D. Biliary atresia.Semin Immunopathol. 2009; 31: 371-381Crossref PubMed Scopus (61) Google Scholar Indeed, approximately 50% and 80% of patients with BA undergo transplantation by age 2 and 20, respectively.2Shneider B.L.

It is conceivable that BA represents a common final phenotypic pathway of neonatal liver injury owing to diverse causes, including developmental, vascular, or infectious factors, that may act antenatally or within the first 3 months of life, in a genetically predisposed individual,4Sokol R.J.

Bile extravasated into periductal tissues would lead to protracted inflammation and fibrosis, causing secondary obliteration and obstruction of the more distal bile ducts. The detergent effect of the extravasated bile, however, cannot be the only explanation for liver damage, because the disease can progress also when the Kasai portoenterostomy achieves adequate bile flow. Proposed etiologies in BA include defective morphogenesis secondary to genetic factors, vascular abnormalities, exposure to toxins, viral infection, and immune-mediated mechanisms. Viral infection and immune mechanisms are the fascinating themes on which the literature has focused in more recent years. The presence of a portal tract mononuclear cell infiltrate at liver histology suggested a primary inflammatory process leading to bile duct obstruction.

The authors search for biliary autoantigens possible targets of humoral immune responses in a rotavirus induced BA animal model and then investigate whether these autoantibodies are present in affected infants. In the animal model part of the study, antibodies to a protein of biliary origin are detected in mice that develop bile duct obstruction after infection with rotavirus at birth. A target of the humoral autoimmune reaction is identified as α-enolase, a 48-kD glycolytic enzyme expressed in most tissues, that shares amino acid sequence similarities with rotavirus-encoded proteins, suggesting a role for molecular mimicry in the generation of the autoantibody. To support this notion, inhibition experiments in which antiviral reactivity is absorbed by incubation of the sera with α-enolase and, conversely, anti-enolase reactivity is absorbed by the use of viral sequences, should be a priority for future studies. Further, cross-reactivity experiments should be applied also to the cellular immune reaction, because the same group demonstrated a pathogenic role for T cells in adoptive transfer experiments. Such work will help in clarifying the relative roles of cellular and humoral autoimmunity in the pathogenesis of BA in the experimental animal model. The authors identify reactivity to α-enolase also in an high proportion of infants with BA and in a smaller proportion of controls, suggesting a role for the autoantibody as a disease biomarker. It should be noted, however, that reactivity to α-enolase is present in autoimmune liver disease,44Terrier B. Degand N.
