Article Title: A Truncation Variant of the Cation Channel P2RX5 Is Upregulated during T Cell Activation
doi: 10.1371/journal.pone.0104692
Figure Lengend Snippet: A, Western blot analysis of P2RX5, talin, and LFA-1 expression in activated CD4 + T cells transfected with siRNA as indicated. GAPDH served as loading control. B, C, CD4 + T cells were transfected with indicated siRNA followed by activation for 4 or 24 h. Cells were stained with anti-talin antibodies. Scale bar – 10 µm. D, Bar diagram illustrating relative number of polarized CD4 + T cells seen with talin or LFA-1 immunostains. E, Bar diagram illustrating interleukin production of activated non-transfected (grey bars), control siRNA (white bars) or P2RX5-siRNA transfected (black bars) CD4 + T cells (n = 3 donors). Error bars are SEM, n.s. – non significant; * - p<0.05, ** p<0.01 (Student's T-test).
Article Snippet: Primary antibodies were anti-P2RX5 (clone 1C5 for immunoblotting or polyclonal for immunocytochemistry, Abnova, Taipei, Taiwan), anti-talin (clone 8d4, Sigma-Aldrich), anti-GAPDH (clone GAPDH-71.1, Sigma-Aldrich) monoclonal mouse antibodies, and anti-LFA-1 (against integrin, alpha-L, clone EP1285Y, Abcam, Cambridge, UK) monoclonal rabbit antibody.
