Key Points

This research aims to understand how the PTBP1-TRAF6 axis affects macrophage polarization and neutrophil extracellular trap clearance in COPD.
Investigated the role of PTBP1 in stabilizing TRAF6 mRNA
Analyzed macrophage polarization patterns
Examined neutrophil extracellular traps (NETs) clearance rates
PTBP1 significantly increases TRAF6 expression
Enhanced M1 macrophage polarization was observed
Impairment in the clearance of neutrophil extracellular traps was noted, contributing to COPD aggravation

Abstract

PTBP1 enhances TRAF6 expression by stabilizing its mRNA, promoting M1 macrophage polarization and impairing NETs clearance, ultimately aggravating COPD.
