claim: sars-cov-2 infection promotes airway motile cilia and impairs mucociliary clearance
evidence_1: rather, sars-cov-2 replication led to a rapid loss of the ciliary layer, characterized at the ultrastructural level by axoneme loss and misorientation of remaining basal bodies.", "this study identifies cilia damage as a pathogenic mechanism that could facilitate sars- cov-2 spread to the deeper lung parenchyma.")
