| 5 | Immune-mediated liver injury following COVID-19 vaccination显示文摘Liver injury secondary to vaccination is a rare adverse event that has recently come under attention thanks to the continuous pharmacovigilance following the widespread implementation of coronavirus disease 2019(COVID-19)vaccination protocols.All three most widely distributed severe acute respiratory syndrome coronavirus 2 vaccine formulations,e.g.,BNT162b2,mRNA-1273,and ChAdOx1-S,can induce liver injury that may involve immune-mediated pathways and result in autoimmune hepatitis-like presentation that may require therapeutic intervention in the form of corticosteroid administration.Various mechanisms have been proposed in an attempt to highlight immune checkpoint inhibition and thus establish causality with vaccination.The autoimmune features of such a reaction also prompt an in-depth investigation of the newly employed vaccine technologies.Novel vaccine delivery platforms,e.g.,mRNA-containing lipid nanoparticles and adenoviral vectors,contribute to the inflammatory background that leads to an exaggerated immune response,while patterns of molecular mimicry between the spike(S)protein and prominent liver antigens may account for the autoimmune presentation.Immune mediators triggered by vaccination or vaccine ingredients per se,including autoreactive antibodies,cytokines,and cytotoxic T-cell populations,may inflict hepatocellular damage through wellestablished pathways.We aim to review available data associated with immunemediated liver injury associated with COVID-19 vaccination and elucidate potential mechanisms underlying its pathogenesis. | Georgios Schinas Eleni Polyzou Vasiliki Dimakopoulou Stamatia Tsoupra Charalambos Gogos Karolina Akinosoglou | 2023 | World Journal of Virology2023，12，2： | 0 |
