Nasal Gene Expression of Angiotensin-Converting Enzyme 2 in Children and Adults

Abstract

This study compares angiotensin-converting enzyme 2 (ACE2) gene expression, which has been associated with SARS-CoV-2 cell entry, in the nasal epithelium of children vs adults.

Data are means (data points) and 95% confidence intervals (error bars) for angiotensin-converting enzyme 2 (ACE2) gene expression in younger children (aged <10 years), older children (aged 10-17 years), young adults (aged 18-24 years), and adults (aged ≥25 years). Gene counts are shown as logarithmic (log2) counts per million. P values are from linear regression modeling in which ACE2 gene expression in log2 counts per million was the dependent variable and age group was the independent variable.
