Figure Lengend Snippet: K2KO does not affect αVβ3, the β1 integrin and AR expression levels on PC cells.

Article Snippet: The PCa cells, upon respective treatments, were incubated (0.5 × 10 6 in 100 μl of HBSS buffer containing 0.1% BSA, 1 mM CaCl 2 , 1 mM MgCl 2 ) with the following antibodies: anti- human αVβ3-AF488 (clone LM609, Millipore Sigma) , anti-human CD29-PE (BD Pharmigen) anti-human CD61-PE (BD Pharmigen), anti-human Annexin V-PE (BD Pharmigen) or anti-human AR-AF488 (Millipore Sigma) at 0.5–1 μg/sample for 30 min on ice.

Figure Lengend Snippet: Evaluation of αvβ6-dependent activation of chimeric G115 γδ TCRs. ( A ) Analysis of integrin expression on A375 puro and A375-β6 cells. Red–integrin; blue–isotype control. Data are representative of 3 independent replicates. Co-cultures were performed between A375 puro ( B ) and A375-β6 ( C ) tumour cells and untransduced (untrans) or transduced T-cell populations at an effector-to-target ratio of 1:1 for 72 h. Residual tumour cell viability was determined using an MTT assay (mean ± SEM of indicated replicates). Statistical analysis was performed using one-way ANOVA; **** p < 0.0001. ( D ) Supernatants collected from co-cultures described in ( B , C ) were analysed for IFN-γ by ELISA (mean ± SEM; n = 21–45 from 4–6 independent donors). Statistical analysis was performed using one-way ANOVA; * p < 0.05; ** p < 0.01.

Article Snippet: Integrin expression was detected by flow cytometry using the following antibodies: αvβ3 integrin (FAB3050A, R&D Systems, Minneapolis, MN, USA), αvβ5 integrin (FAB2528A, R&D systems), αvβ6 integrin (FAB4155A, R&D Systems) and αvβ8 integrin (FAB4775A, R&D systems).

Figure Lengend Snippet: Evaluation of PAg-dependent activation of chimeric G115 γδ TCRs by ffLuc-expressing K562 cells. ( A ) Analysis of αvβ6 integrin expression on ffLuc + K562 cells. Red–integrin; blue–isotype control. Data are representative of 3 independent replicates. ( B ) Firefly luciferase-expressing K562 cells were pre-incubated with the indicated Zol concentration for 24 h prior to the establishment of co-cultures with untrans(duced) or transduced T-cell populations at an effector to target ratio 1:1 for 72 h. Data show mean ± SEM of residual K562 viability (n = 6–11 from 4 independent donors), as determined by luciferase assay. Statistical analysis was performed using two-way ANOVA; *** p < 0.001; **** p < 0.0001. ( C ) Supernatants collected from co-cultures described in B were analysed for IFN-γ by ELISA (mean ± SEM; n = 19 from 3 independent donors). Statistical analysis was performed using two-way ANOVA; *** p < 0.001; **** p < 0.0001.

Figure Lengend Snippet: Evaluation of the anti-tumour activity of chimeric G115 γδ TCRs against BxPC3 pancreatic tumour cells. ( A ) Analysis of integrin expression on BxPC3 cells. Red–integrin; blue–isotype control. Data are representative of 3 independent replicates. Co-cultures were performed between BxPC3 tumour cells (No Zol; B ) or Zol-sensitised BxPC3 tumour cells (+Zol; C ) and untrans(duced) or transduced T-cell populations at an effector to target ratio of 1:1 for 72 h. Tumour cell viability was determined using an MTT assay (mean ± SEM of indicated replicates). Statistical analysis was performed using one-way ANOVA; **** p < 0.0001, * p < 0.05, N/S–not significant.
