Several parameters were optimized for each antibody in the multiplex IF assay. Polarisation under different conditions drives macrophage with a range of inflammatory (M1) or anti-inflammatory (M2) phenotypes. NCI CPTC Antibody Characterization Program. Hong SM, Noe M, Hruban CA, Thompson ED, Wood LD, Hruban RH. Nat Rev Cancer (2012) 12:298–306. In addition to analyzing the spatial relationship of MC&M-associated pixel populations and tumor cells, we performed a similar analysis for pixel classes and CD3+ T cells. (C) Antibody staining patterns using mIF. HG, LW, SS, and AG: Data interpretation. Nuclei are outlined in the DAPI DAPI channel. doi: 10.1016/j.cellimm.2018.01.001, 7. doi: 10.1038/nmeth.2869, 52. Myeloid cells in inflammation. An automated staining protocol for seven-colour immunofluorescence of human tissue sections for diagnostic and prognostic use. Thresholds were based on the negative isotype controls included in every staining batch (not shown) and to remove artifacts, groups of fewer than 9 adjacent pixels were excluded from further analysis. Upon foam cell formation, SMCs express lower levels of typical SMC markers (α‐SM actin and α‐tropomyosin) and increased levels of macrophage markers such as CD68, galectin 3 and the macrophage foam cell marker ABCA1 89. (A) Workflow diagram of overlay of CD3+ T cell mask and CD163-mask in tile labeled IHC/IF and illustration of distance measurement. (B) Representative image tile of mIF 5-plex. Interestingly, a unique feature in renal cancer was an abundance of CD68+/CD11c+ (2.2–13% of the CD68-mask) and CD68+/CD163+/CD11c+ (3.5–15%) pixels. The mask of cancer cells was obtained through the machine learning module built into the InForm ver. Cancer Metastasis Rev. J Immunother Cancer (2015) 3:42. doi: 10.1186/s40425-015-0088-7, 53. The trained module was applied to image tiles from IHC slides and yielded binary masks with cancer epithelium in the foreground (white pixels) and the remaining tissue components in the background (black pixels). (D) Frequencies of single and double positive MC&M-associated pixel classes. While CD8+ T cells are regulated by MC&Ms, the systematic profiling of and immunophenotyping of MC&Ms by tissue imaging has not advanced as rapidly as that of T cells. Receive the latest news and insights to your inbox. The P2,3,4,5 fraction includes all pixels colored by more than one antibody. ab52632), MRC1 (CD206) (clone CL0387 mouse mAb, Sigma-Aldrich cat. One such alternative function of autophagy proteins is LC3-associated phagoc … This is accomplished by heat retrieval using citrate buffer pH 6.0. The largest pixel fraction was CD163+/CD206+ (Figure 3C, Supplementary Table 2). We implemented the affine image co-registration procedure (37) to transfer the tumor or T cell masks from the IHC to the corresponding IF images based on nuclear staining intensities of hematoxylin and DAPI. We adopted the same approach that was used by these authors to demonstrate the staining specificity of our MC&M antibody panel (Figure 1D). All primary and secondary antibody incubations are conducted at 37°C. HHS Wynn TA, Chawla A, Pollard JW. Nat Rev Cancer (2013) 13:739–52. In addition, the P3, 4, 5 fraction, which are pixels colored by more than two antibodies are shown. MC&M counts obtained through nuclear segmentation were correlated with MC&M-associated pixel areas obtained by the pixel-based segmentation. We focused on the roles of macrophages because these cells were the predominant cell type infiltrating joint tissues of CIA mice (Fig. Values and tile numbers in Supplementary Table 8. Interestingly, the enzyme responsible for the synthesis of 27HC, CYP27A1, is highly expressed in myeloid cells, suggesting that 27HC may have important autocrine or paracrine functions in these cells, a hypothesis supported by our finding that breast cancer metastasis was reduced in mice with a myeloid specific knockout of CYP27A1. doi: 10.1038/bjc.2017.356, 44. Multiplex antibody staining with sequential IF and IHC (PLEXODY assay). Myeloid precursors can differentiate into multiple cell types, one of which is the macrophage. Figure 5. Immunol. The imaging using filter cubes is not compromised by the bleed over of fluorophore signals and can be used with fluorescent signals of different staining intensities. Similar to CD68+ pixels, the majority of CD163+ pixels were single positive (6–72% of CD163-masks). Corresponding representative digital images of mIF and mIHC in Supplementary Figures 4–12. J Immunother Cancer (2018) 6:48. doi: 10.1186/s40425-018-0368-0. (2015) 21:3428–35. The low CD163+/CD206+ included the other 5 of the 9 cancer cases with frequencies of CD163/CD206+ pixels less than 3% of the CD163-mask. Next, we further dissected the P2,3,4,5+ pixel populations by quantifying four double positive pixel classes, CD68+/CD163+, CD68+/CD11b+, CD68+/CD11c+, and CD163+/CD11c+. PLoS ONE (2015) 10:e0139866.  |  Br J Dermatol. The assay, named PLEXODY, incorporates automated multiplexed IF (mIF) and multiplex IHC (mIHC) tissue staining, digital image co-registration and data extraction and combines the quantitative strength of IF with the diagnostic capacity of IHC.
