“…Here, we propose different mechanisms related to cardiac irAEs, such as autoantibody production. Autoantibodies induced by ICI therapy include anti-acetylcholine receptors, striated muscle, mitochondria, alanyl-tRNA synthetase, SRP-B, and 3-hydroxy-3-methylglutaryl-coenzyme, these autoantibodies were found too in a recent systematic review published by ( Ghosh et al, 2022 ), and despite that, we did not study the association of ICI-induced autoantibodies and anti-cancer efficacy, where some authors propose that the irAEs are associated with better antitumoral effect or trend for better survival ( de Moel et al, 2019 ; Les et al, 2021 ). Furthermore, the recent finding by Bocksthaler et al, 2021 showed that Troponin I (TnI)-directed autoimmune myocarditis (TnI-AM) is mediated by CD4 + T-cells, and the immunoproteasome is a key player in this autoimmunity.…”
