In vivo antiviral host response to SARS-CoV-2 by viral load, sex, and age [dataset I]


ABSTRACT: We examined host gene expression across infection status, viral load, age, and sex among RNA-sequencing profiles of nasopharyngeal swabs from 430 individuals with SARS-CoV-2 and 54 negative controls. SARS-CoV-2 induced a strong interferon-driven antiviral response and reduced transcription of ribosomal proteins. Expression of interferon-responsive genes, including ACE2, increased as a function of viral load. B cells and neutrophils were higher in patients with lower viral load. Older individuals had reduced expression of chemokines CXCL9/10/11, their cognate receptor CXCR3, and CD8A and granzyme B. Males had reduced B and NK cell-specific transcripts and increased NFkB inhibitors. Our data demonstrate that host responses to SARS-CoV-2 are dependent on viral load and infection time course, with observed differences due to age and sex that may contribute to disease severity.
