For instance, mouse models of COVID‐19 (eg by adeno‐associated virus–mediated expression of human ACE2 in the respiratory tract followed by experimental SARS‐CoV‐2 infection) and GBS (eg EAN induction by sensitization with peripheral nerve homogenate or by immunization with myelin proteins) could be combined to study the immunopathogenesis of COVID‐19–associated GBS.38, 39. The gene discussed is ACE2; the disease is COVID-19.
