Title	Proteomic signature of host response to SARS-CoV-2 infection in the nasopharynx
Description	Coronavirus disease 2019 (COVID-19), caused by SARS-CoV-2 infection has become a global health pandemic. COVID-19 severity ranges from asymptomatic infection to severe multi-organ disease. Although the inflammatory response has been implicated in the pathogenesis of COVID-19, the exact nature of dysregulation in signaling pathways has not yet been elucidated underscoring the need for further molecular characterization of SARS-CoV-2 infection in humans. Here, we characterize the host response directly at the point of viral entry through analysis of nasopharyngeal swabs. Multiplexed high resolution mass spectrometry-based proteomic analysis of confirmed COVID-19 cases and negative controls identified 7,682 proteins and revealed significant upregulation of interferon-mediated antiviral signaling in addition to multiple other proteins that are not interferon-stimulated genes (ISGs) or well-characterized during viral infections. Downregulation of several proteasomal subunits, E3 ubiquitin ligases, and components of protein synthesis machinery was significant upon SARS-CoV-2 infection. Targeted proteomics to measure abundance levels of MX1, ISG15, Stat1, RIG-I and CXCL10, permitted differentiation of COVID-19 positive from negative cases. Phosphoproteomic analysis revealed increased phosphorylation of several proteins with known antiviral properties and as well as several proteins including CEP131, CFAP57 and xxxx that have not previously been implicated in the context of viral (or coronavirus) infections. Additionally, decreased phosphorylation levels of AKT and PKC, which have been shown to play varying role in different viral infections, were observed in infected individuals relative to controls. These data provide novel insights that add depth to our understanding of SARS-CoV-2 infection in the upper airway and help characterize a signature for this viral infection.
