Antibacterial Neutrophil Effector Response: Ex Vivo Quantification of Regulated Cell Death Associated with Extracellular Trap Release

Methods Mol Biol. 2023:2674:235-250. doi: 10.1007/978-1-0716-3243-7_16.

Abstract

Regulated cell death (RCD) and the concomitant release of extracellular traps by neutrophils (NETs) constitute an important antibacterial effector response. Usually, the dynamic processes of RCD and NETs release are assessed independently of each other by either unspecific or time-consuming methods. Here, we describe a flow cytometry-based high-throughput analysis method incorporating neutrophil RCD and NETs release with visual live-imaging conformation upon ex vivo bacterial challenge. This combined approach allows to quantify and closely follow the kinetics of the dynamic neutrophil effector response towards bacterial infection.
