Acute lung injury induced by recombinant SARS-CoV-2 spike protein subunit S1 in mice.

ABSTRACT:

Background

The intricacies of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causing acute lung injury (ALI) and modulating inflammatory factor dynamics in vivo remain poorly elucidated. The present study endeavors to explore the impact of the recombinant SARS-CoV-2 spike protein S1 subunit (S1SP) on ALI and inflammatory factor profiles in mice, aiming to uncover potential therapeutic targets and intervention strategies for the prevention and management of Coronavirus Disease 2019 (COVID-19).

Methods

To mimic COVID-19 infection, K18-hACE2 transgenic mice were intratracheally instilled with S1SP, while C57BL/6 mice were administered LPS to form a positive control group. This setup facilitated the examination of lung injury severity, inflammatory factor levels, a
