Figure Lengend Snippet: Distribution of CD163 + M2 TAMs in AKR-derived allograft tumor tissues from immunocompetent C57BL/6 mice. (a, b) Representative IHC staining images showing CD163 + M2 TAMs in the (a) peritumoral stroma and (b) tumor islets. Lower panels display higher-magnification views of the regions outlined by red dashed boxes. (c, d) Quantification of CD163 + cells in the (c) peritumoral stroma and (d) tumor islets. (e) Comparison of CD163 + cell density between the peritumoral stroma and tumor islets. (f) Total number of CD163 + cells in allograft tumors (peritumoral stroma and tumor islets combined). (g, h) Comparison of the density between iNOS + cells and CD163 + cells in the (g) peritumoral stroma and (h) tumor islets. (i, j) Quantification of iNOS + /CD163 + ratio in the (i) peritumoral stroma and (j) tumor islets. p < 0.05 (∗), p < 0.01 (∗∗), p < 0.001 (∗∗∗). A field of view is ∼0.086 mm 2 in (c−j).

Article Snippet: Tissue sections were then incubated with primary antibodies against iNOS (22226-1-AP, ProteinTech, China), CD163 (A26411PM, Abclone, China), CD8 (SP16, Maixin, China), CD4 (SP35, Maixin, China) or Ki-67 (12202S, Cell Signaling Technology) for 12 h at 4 °C, followed by secondary antibodies (Beyotime Biotechnology, Nantong, China).

Article Title: MT2A-Mediated Regulation of Cuproptosis in Human Dental Pulp Cells Modulates Macrophage M1 Polarization in Pulpitis

doi: 10.1016/j.identj.2026.109506

Figure Lengend Snippet: MT2A knockdown in hDPCs cuproptosis model enhances macrophage migration and M1 polarization, A. Pearson correlation coefficients among immune cells and the MT2A in human pulp tissues from GEO database ( GSE92681 and GSE77459 ); B .Immunofluorescence staining of CD68 protein in human healthy pulp tissues (n = 3) and pulpitis tissues (n = 3); C. Transwell assays detected the migration of macrophages (n = 3); D. Flow cytometry detected the polarization of macrophages by the expression of CD80 and CD163 (n = 3).

Article Snippet: The cells were resuspended with 300 μL PBS and incubated with antibodies against human CD163 (PTM Bio) and CD80 (Affinity Biosciences) for 1 h on ice.
