Figure Lengend Snippet: Vagotomy promoted Ly6G + cell infiltration into eWAT. Wild‐type mice were subjected to left cervical vagotomy (VX) or sham surgery and tissues were collected at 7 days following surgery. (A) The percentage of non‐adipocyte nuclei of total nuclei per section was quantified using ImageJ ( n = 4) and right panels show representative images of paraffin sections of eWAT stained with H&E in sham and VX animals. (B) CCL2 release from eWAT was analyzed by ELISA. The bar shows the CCL2 levels from sham ( n = 4) or VX ( n = 4) mice normalized to eWAT weight: ng/mL per g ± SEM (unpaired Student's t test). (C) eWAT was collected at 1 ( n = 3), 4 ( n = 4 sham, n = 5 VX), and 7 ( n = 15) days following VX or sham surgery and the eWAT SVCs were analyzed by flow cytometry. The bar shows the % ± SEM of CD11b + Ly6G + cells from CD45 + (one‐way ANOVA, Uncorrected Fisher's LSD). (D) Graphs show representative gating for CD11b + Ly6G + cells in sham and VX eWAT at 7 days (concatenated n = 5–6). (E) Representative immunostaining of Ly6G (red) and Perilipin1 (green) in paraffin sections of eWAT. (F–H) Bone marrow neutrophils after sham ( n = 9) or VX ( n = 5) surgery were isolated using negative magnetic beads and analyzed using bulk RNAseq (DESeq2).

Figure Lengend Snippet: Temporary extracellular Ly6G depletion effect on VX‐associated reduction of eWAT weight. (A) Flow cytometry analysis of the frequency of extracellular Ly6G and CD11b double positive cells following one intraperitoneal injection of either anti‐Ly6G or vehicle (PBS). Bars show the % ± SEM of CD11b + Ly6G + in vehicle ( n = 4–5) and at 1 ( n = 2), 2 ( n = 4), 5 ( n = 4), and 9 ( n = 3) days following injection in eWAT, blood, and bone marrow (one‐way ANOVA, Šídák's multiple comparisons test).

Figure Lengend Snippet: The identification of the source of IL-27. (A–D) The intracellular co-label staining by flow cytometry was applied to determine the source of IL-27. The four APCs were labeled by dendritic cell (CD11b, CD11c, B), neutrophil (CD11b, Ly6G, C), monocyte (CD11b, Ly6C, A), and macrophage (CD11b, F4/80, D), respectively. IL-27p28 antibody labeled the IL-27. The results indicated that neutrophil/monocyte-derived IL-27 was highly expressed in serum and spleen. IL: interleukin, APCs: antigen-presenting cells, SSC-A: side scatter area.
