Tropism, replication competence, and cellular responses of HAdV-14p1 in human airway organoids

Sep 29, 2026

Uploaded by Adam

Human adenovirus type 14p1 (HAdV-14p1) drives severe respiratory disease. Using human airway organoids, the study maps viral tropism, infection dynamics, and host cellular responses, and tests the antiviral potential of cidofovir. HAdV-14p1 robustly infects and replicates, with preferential targeting of ciliated, basal, and goblet cells. Infection markedly increases inflammatory mediators and activates p53-related and cytokine signaling programs, while reducing tight-junction and metabolic/oxidative phosphorylation pathways. Cidofovir suppresses replication with low organoid cytotoxicity.

Using human airway organoids, we characterized the cellular tropism, infection dynamics, and cellular response to HAdV-14p1 , and evaluated the antiviral efficacy of cidofovir. HAdV-14p1 robustly infected and replicated in human airway organoids, particularly targeting ciliated, basal, and goblet cells. CCL5, CXCL10, CXCL11, and TNFSF13B were significantly upregulated upon HAdV-14p1 infection, indicating inflammatory activation. Pathway enrichment analysis revealed that upregulated genes were enriched in p53 signaling, cytokine-cytokine receptor interaction, and NOD-like receptor signaling pathways, whereas downregulated genes were linked to focal adhesion, tight junction, metabolic pathways, and oxidative phosphorylation pathways. Furthermore, treatment with cidofovir effectively inhibited viral replication with low cytotoxicity. Our findings highlight the robust replication and proinflammatory response that shape HAdV-14p1 pathogenesis and underscore the value of organoid systems in probing virus-host interactions and evaluating candidate antiviral strategies. INTRODUCTION Human adenovirus (HAdV) is a highly contagious pathogen that causes a broad spectrum of clinical illnesses, including respiratory tract diseases, conjunctivitis, gastroenteritis, and urinary tract infections.1 At least 113 HAdV types are recognized ([http://hadvwg.gmu.edu/](http://hadvw
