Article Title: Serglycin modulates inflammation and metabolism in macrophages

doi: 10.1016/j.isci.2026.115235

Figure Lengend Snippet: SRGN deficiency reshapes the inflammatory secretome and transcriptional programs in human macrophages (A) Volcano plot of differentially secreted proteins between SRGN −/− and wild-type THP-1 macrophages under M1 polarization. Among 1,507 quantified proteins, 53 were significantly altered (adjusted p < 0.05), with serglycin being the most downregulated protein in knockout cells. (B) Validation of selected targets by RT-qPCR. SRGN −/− M1 macrophages showed significantly increased expression of IL6 and TNF and reduced expression of CCL5 compared with wild-type cells (mean ± SEM; unpaired Student’s t test; p < 0.05, ∗ p < 0.01, and ∗∗∗ p < 0.0001; n = 4). (C) ELISA quantification of secreted cytokines in culture supernatants. SRGN −/− macrophages secreted significantly less TNF-α, CCL5, and IL-6 compared with wild-type macrophages ( n = 4), consistent with proteomics and RNA-seq data. (D) Transmission electron microscopy (TEM) images of THP-1 M0 and M1 macrophages. Scale bars, 5 μm. Vesicles were manually annotated and quantified in 10 cells per experimental group. The number of vesicles per cell and the percentage of cellular area occupied by vesicles were significantly reduced in both M0 and M1 SRGN −/− macrophages compared with wild-type macrophages. (E) Phagocytosis assay using fluorescently labeled bioparticles. SRGN −/− macrophages exhibited reduced phagocytic capacity under both M0 and M1 conditions (mean ± SEM; unpaired Student’s t test; p < 0.05 and ∗∗ p < 0.001; n = 6).
