For neutrophil depletion, mice were injected via the tail vein with 200 µg per mouse of a neutrophil-depleting antibody (anti-Gr1; BioLegend, clone RB6-8C5) or the isotype control (IgG2b; BioXCell, clone LTF-2) 24 h before glycerol-mediated injury of the TA muscle. Subsequently, these mice were further injected by i.p with another neutrophil-depleting antibody (anti-Ly6G; BioXCell, clone 1A8, 200 µg per mouse) or the corresponding isotype control (IgG2a; clone 2A3, 200 µg per mouse) 48 h and 96 h after the first dose of neutrophil-depleting antibody. BALB/c male mice (The Jackson Laboratory, JAX#000651) at 3 months of age were utilized for these experiments because anti-Gr1 and anti-Ly6G antibodies work better in this strain to deplete neutrophils73 (link),135 (link)–137 (link).
