## Abstract

Project Summary/Abstract
 In this Competitive Revision proposal, we seek to investigate the non-cell autonomous effects of Covid-
19 infections in olfaction. Our preliminary data suggest that induction of pro-inflammatory/antiviral pathways
result in disruption of inter-chromosomal genomic interactions, and downregulation of Olfactory Receptor (OR)
gene expression. Since antiviral responses are expected be elicited upon Covid-19 infection, we hypothesize
that disruptions in nuclear architecture and OR expression account for the reported olfactory deficits in infected
patients. Thus, we propose to analyze human autopsies of the olfactory epithelium, to decipher whether Covid-
19 infections disrupt genomic interactions required for OR transcription. We will complement our studies in
human autopsies with experiments using mice infected with SARS-CoV-2. RNA-seq, in situ HiC and
immunohistochemistry experiments in human and mice will reveal the molecular mechanisms by which Covid-
19 induces olfactory dysfunction. Our experiments will provide critical insight to the mechanisms by which the
virus hijacks molecular and physiological processes of the host cell, opening new potential avenues for the
prevention, diagnosis and treatment of Covid-19 infection.
