Neutrophil production of LTB4 and the release of another chemoattractant, chemokine CXCL2 (C-X-C motif chemokine ligand 2), is responsible for the collective coordinated behavior of neutrophils, called swarming, which is important for protection against severe pathogen infection (Lammermann et al., 2013; de Oliveira et al., 2016; Rocha-Gregg and Huttenlocher 2021). This evidence concerns the gene CXCL2 and infection.
