Article Title: The CXCL9/SPP1 polarity axis in tumor-associated macrophages: immunoregulatory and prognostic significance in non-small cell lung cancer

doi: 10.3389/fimmu.2026.1763652

Figure Lengend Snippet: Validation of CXCL9 + and SPP1 + macrophage expression and polarization characteristics in lung cancer tissues. (A) Representative mIF staining for CXCL9+ TAMs and SPP1+ TAMs in lung tissue sections from the normal and LUAD tumor groups. DAPI (blue), CD68 (red), CXCL9 (yellow), SPP1 (green) are shown, along with individual and merged channels. (n = 3 per group). Scale bar, 20 μm. (B) Representative mIF staining of CXCL9+ TAMs (yellow) and SPP1+ TAMs (green) in lung tissue sections from the normal and LUAD tumor groups (n = 3 per group). Scale bar, 20 μm. (C) qRT-PCR validation of macrophage polarization. The M1 group showed high expression of Cxcl9 and iNOS, while the M2 group showed high expression of Spp1 and Arg1. Asterisks indicate statistically significant differences (*p < 0.05).

Article Snippet: Following another stripping step, the third round was performed using mouse anti-human CD68 monoclonal antibody (1:50000, Servicebio, Cat# GB153150 ) with HRP-conjugated goat anti-mouse secondary antibody (ready-to-use, Servicebio, Cat# G1301), and signal was developed using iF555-Tyramide (1:500, Servicebio, Cat# G1233).

doi: 10.1016/j.jare.2025.06.076

Figure Lengend Snippet: CCR1-overexpressing macrophages induce T and B cell migration. (A) Immunofluorescence (IF) detection of CD68 expression in THP-1 cells induced by PMA (100 nM, 24 h). (B) Quantitative analysis of CD68 expression based on IF staining fluorescence intensity. (C) Schematic diagram of the detection of macrophage-induced T and B cell migration. (D, E) Western blot analysis and quantitative evaluation of CCR1 and CCL5 expression in macrophages after transfection with the CCR1 overexpression plasmid. (F) ELISA measurement of CCL5 concentration in supernatants from CCR1-overexpressing macrophages. (G, H) Transwell assay evaluating macrophage-mediated migration of T and B cells, with quantitative analysis of migrated cell numbers. Statistical significance was determined using one-way ANOVA.

Article Snippet: To induce differentiation into macrophages, THP-1 cells were treated with 100 nM PMA for 24 h. Differentiation was confirmed by immunofluorescence analysis of CD68 localization and expression using a mouse anti-CD68 antibody (1:500, 66231–2-Ig, Proteintech, Wuhan, China).
