Figure Lengend Snippet: ( A ) The experimental design and the CNA genetic landscape of tumors in patients St23784/17 and Ti41749/17, showing that St23784/17 had amplifications at the 3q, 6q, 8q, 9q, and 10q22.1 regions of stemness gene localization (the following genes were amplified: SOX2 , MYC , KLF4 , NOTCH1 , NODAL ), and Ti41749/17 had no stemness gene amplifications. ( B – E ) Analysis of the quantitative and qualitative expression of cells obtained from tumor tissue of breast cancer patients. The cells were analyzed by flow cytometry using a FACSCanto II (Becton Dickinson, USA) and FACS Diva software, using CD326 (PerCP-Cy5.5), CD24 (PE-Cy 7), and CD44 (APC) (BD Biosciences, USA) antibodies. (B) Histogram of the IgG1 PerCP Cy5.5 isotope control; (C) isotype control dot-plot for IgG2a PE-Cy 7/IgG2b APC; (D) phenotypic confirmation and qualitative analysis of CD326 (PerCP-Cy5.5) expression in the histogram; (E) phenotypic confirmation and qualitative analysis of CD326 + CD44 + CD24 -\low expression in the dot-plot. ( F ) The dynamics of the EpCam+ tumor cell mass increase (percentage of the initial number of cells in culture). ( G ) Nonadherent mammospheres of EpCam + cancer cell cultures (St23784/17 patient). Mammosphere formation within 10 days. Scale bar, 200 μm. ( H ) EpCam + cells without mammosphere formation (patient Ti41749/17). ( I ) Thermal map of stemness gene expression in the environment enriched with EpCam+ tumor cells from the patients St23784/17 and Ti41749/17. ( J ) The content of tumor stem cells in the EpCam + cell enriched environment after a cycle of cultivation and IL-6 treatment (% of the initial cell content in each population).

Figure Lengend Snippet: γδ T cell reactivity accounts for the majority of the mouse extract response and is not mediated by peptides Total MO-specific T cell responses were measured as a percentage of AIM + (CD137 + CD69 + ) CD3 + T cells after stimulation of PBMCs with MO extract, and the individual γδ and αβ T cell reactivity was assessed. (A) Representative FACS plot of total AIM + CD3 + T cells (left) further gated as function of γδ and αβ T cell reactivity (right) (B) Graph shows the relative percentage of γδ and αβ reactivity from the total MO-specific T cell responses across all donors (n = 33). (C) (Left) Representative FACS plots of AIM + (CD137 + CD69 + ) γδ (top row) or αβ (bottom row) T cells after stimulation of PBMCs with MO peptide pools (MPs), MO extract, or control (Neg; media for γδ T cells, or DMSO for αβ T cells). (D) Graphs show the percentage of AIM + reactivity in each condition for γδ or αβ T cells across all donors (n = 20). All graphs show data represented as geometric mean with SD. Each dot represents a unique individual. Pairwise comparisons were performed with the Wilcoxon test, and p values <0.05 were considered statistically significant.

Figure Lengend Snippet: γδ T cell reactivity to MO and CR allergen extracts is TCR specific, albeit with different requirements for the presence of APCs (A–C) Allergen-specific γδ T cell responses were measured as percentage of AIM + (CD137 + CD69 + ) γδ T cells after stimulation of PBMCs with (A) MO extract, (B) CR extract, or (C) HDMAPP in the presence (+) or absence (−) of antigen-presenting cells (APCs). (D and E) PBMCs were stimulated with an MO or CR extract, HDMAPP, or α-CD3 and cultured in the absence (−) or presence (+) of a TCR blocking reagent (dasatinib). Graphs show percentage of AIM + γδ (D) or αβ (E) T cells in response to the different stimuli and conditions (MO, n = 8; CR, n = 8; HDM, n = 16; TG, n = 16). Each dot represents a unique individual. Data are represented as geometric mean and SD. Kruskal-Wallis or Wilcoxon paired tests were performed, and p values are indicated. p < 0.05 was considered statistically significant.
