Single-cell RNA sequencing of alveolar macrophages in GRP75 knockdown mice with SARS-CoV-2 N protein-induced lung injury

Listed in NCBI GEO

This study investigates the role of GRP75 (Hspa9)-mediated mitochondria-associated membranes (MAMs) in SARS-CoV-2 nucleocapsid (N) protein-induced acute lung injury.

Description

Using single-cell RNA sequencing of lung macrophages from control and GRP75 knockdown mice, we demonstrate that N protein promotes GRP75-dependent ER-mitochondria tethering, leading to mitochondrial calcium overload and proinflammatory macrophage activation.

GRP75 knockdown attenuates N protein-induced lung injury by reprogramming alveolar macrophage identity from a pro-inflammatory Car4+ state to a metabolically quiescent Hspa9-low state.
