Figure Lengend Snippet: Effects of IL‐17A neutralisation on macrophage polarisation in SHR renal tissues. (A) Representative IHC staining of M1 macrophage markers (iNOS and CD86) with quantitative analysis of their positive areas. (B) Representative IHC staining of M2 macrophage markers (Arg‐1 and CD163) with quantitative analysis of their positive areas. (C) Representative immunoblots and relative expression levels of iNOS, CD86, Arg‐1, and CD163 proteins. (D) Proportion of CD86 + and CD163 + cells among CD68 + macrophages. (E) mRNA expression levels of iNOS, CD86, Arg‐1, and CD163. Data are presented as mean ± SD ( n = 6).

Figure Lengend Snippet: Figure 3. T cell subsets have distinctive spatial proteome signatures in colorectal tumor microenvironment (A and B) Ranking of protein quantified in cytotoxic T cells (CTLs) (A) and helper T cells (TH) (B), ranked by median transformed intensity values detected by mass spectrometry, with cell-type-specific markers highlighted. (C and D) Volcano plots illustrating proteomic comparisons of CTLs (C) and TH (D) between the lamina propria and tumor epithelial regions, with T cell-activity- related markers highlighted. Significantly enriched proteins are denoted as yellow or green dots (two-sided t test, false discovery rate [FDR] < 0.05, S0 = 0.1, n = 3). (E and F) Gene Ontology (GO) term analysis of significantly altered proteins in CTLs (E) and TH (F) residing in the lamina propria and tumor epithelial regions.

Article Snippet: For CD4 + ARG1 staining, the sections were incubated overnight at 4 C with primary antibodies (anti-CD4-FITC, 1:100, R&D FAB8165G; anti-ARG1-PE, 1:200,Miltenyi Biotec 130-127-839) in a humidified chamber.

Figure Lengend Snippet: Figure 5. Cytotoxic T cells (CTLs) exhibit close proximity to tumors with a suppressive impact on tumor proliferation (A) Density gradient in the background indicates distance to tumor islands, with brighter yellow representing greater distance from tumor cells. Left panel only has the gradient whereas the middle, zoomed panel additionally depicts yellow masks of the CTLs and the right panel red dots of helper T cells (TH), respectively. (B) Representative images showcasing markers for T cell phenotyping. (C) T cell gating based on the expression of CD3, CD8, CD45RA, CD45RO, and PD1 to analyze the corresponding T cell subpopulations. (D) Representative images showing CD3- and CD8-positive CTLs in tumor parenchyma (TIL-CTLs) with absent CD45RA and CD45RO expression. (E) Distance heatmap depicting proximity and interactions between tumor cells and T and B lymphocyte subtypes, with lower values indicating higher proximity as in Figure 4E. (F) Histogram of Ki67/Ki67+ tumor cell number as a function of distance from RARO CTLs. Data represent three technical replicates. Statistical significance was determined using one-way ANOVA. ***p < 0.001, **p < 0.01. (G) Representative image displaying masks of tumor cells at varying proximities to RARO TIL-CTLs.
