- Western blot was performed using Anti-ST2 Polyclonal Antibody (Product # PA5-20077) and a ~63 kDa band corresponding to Interleukin-1 receptor-like 1 was observed across cell lines tested . Membrane enriched extracts (50 µg lysate) of iPSC (Lane 1), iPSC differentiated into cardiomyocytes (Lane 2), K-562 (Lane 3), U-937 (Lane 4) were electrophoresed using NuPAGE™ 4-12% Bis-Tris Protein Gel (Product # NP0321BOX). Resolved proteins were then transferred onto a nitrocellulose membrane (Product # IB23001) by iBlot® 2 Dry Blotting System (Product # IB21001). The blot was probed with the primary antibody (1 µg/mL) and detected by chemiluminescence with Goat anti-Rabbit IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A27036,1:20000) using the iBright FL 1000 (Product # A32752). Chemiluminescent detection was performed using SuperSignal™ West Pico PLUS Chemiluminescent Substrate (Product # 34580).Increased expression observed in cardiomyocyte differentiated iPSCs and K-562 as compared to in U-937.

- Figure 4 Transient EGFR Expression Licenses Th2 Cells to Express IL-13 in Response to IL-33 (A) Splenocytes were isolated from H. polygyrus -infected WT and Egfr fl/fl xCd4-cre (EGFR DeltaCD4 ) mice, and expression of EGFR on T cells was determined by flow cytometry analysis after overnight incubation with H. polygyrus excretory-secretory products (HES), adult worm extract (HEX), anti-CD3, vehicle (C), rIL-7, rIL-2, rTSLP, or rIL-33 (upper). Alternatively (lower), splenocytes were stimulated overnight with rTSLP, and subsequently, IL-13 expression by T cells was analyzed by intra-cellular cytokine staining and flow cytometry analysis following re-stimulation with rIL-33 or anti-CD3 antibody. (B) Ly5.2 + WT mice were infected with H. polygyrus , and 2 weeks after infection, mLN cells were transferred into naive Ly5.1 + hosts. Spleens of recipient mice were harvested after 0-3.5 days post transfer, and the expression of EGFR (upper) and T1/ST2 (lower) on transferred Ly5.2 + CD4 + T cells was determined by flow cytometry analysis. Expression of IL-13 (upper) and IL-5 (lower) upon exposure to rIL-33 was determined by intra-cellular cytokine expression and flow cytometry analysis (n = 3 mice). (C) WT H. polygyrus -infected mice were treated with pyrantel embonate, and mLN were harvested after 0-6 days post treatment. EGFR (upper) and T1/ST2 (lower) expression on CD4 + T cells was determined by flow cytometry, and expression of IL-13 (upper) and IL-5 (lower) upon exposure to IL-33

- Figure 5 EGFR Expression on Th2 Cells Is Induced by TCR Activation and Maintained by Cytokines (A-E) WT H. polygyrus -infected mice were either treated with pyrantel embonate or left untreated; mLN were collected 14 days after treatment. (A) EGFR expression on activated (CD69 + , red bars) or memory (CD25 - CD45RB low CD44 hi , blue bars) CD4 + T cells was analyzed by flow cytometry. (B) Activated CD4 + T cells were flow cytometry-sorted from infected mice into ST2 + EGFR + (red) and ST2 + EGFR - (orange) populations. Memory CD4 + T cells (CD25 - CD45RB low CD44 hi ) were flow cytometry-sorted from dewormed mice. (C) After sorting, activated EGFR + and memory cells were stimulated with rIL-33 or media only, and expression of IL-13 was determined by flow cytometry analysis. (D-E) Activated EGFR - and memory cells were cultured overnight with rTSLP or anti-CD3 antibodies, and expression of EGFR on CD4 + T cells was determined by flow cytometry analysis (D) or were re-stimulated with rIL-33 and expression of IL-13 determined by intra-cellular cytokine staining and flow cytometry analysis (E). (F-G) Egfr fl/fl xCd4-cre (EGFR DeltaCD4 ) mice were infected with H. polygyrus and received either flow cytometry-sorted activated CD4 T cells (red) (F) or flow cytometry-sorted naive or memory T cells (blue) (G) from OVA-challenged mice. Worm burden and egg counts in feces were determined 2 weeks post transfer. Data in (A)-(E) are representative of at least two independent experiments (me

Representative images of human mammary carcinoma with and without necrosis (H&E, original magnification: x100, scale bar: 200mum; x200, scale bar: 100mum). IL-33, IL-33R and VEGF expression was evaluated by immunohistochemistry for each patient (original magnification: x100, scale bar: 200mum; x200, scale bar: 100mum). The difference in the expression of immunohistochemical markers was examined between tumors with and without necrosis. B. , C. Correlation between IL-33 and IL-33R with VEGF expression in tumor cells in human mammary carcinoma tissues. Statistical significance was tested by Mann-Whitney Rank Sum test, independent samples t-test or Spearman correlation coefficient.
