Article Title: Rat P2X7 Receptor Show Functional Independence Between Macropore Formation and Scavenger Activity
doi: 10.3390/ijms27041922
Figure Lengend Snippet: Rat P2X7A exhibits macropore activity. ( A ) Representative flow cytometry histograms showing ethidium bromide (EtBr) uptake in HEK293-P2X7A cells stimulated with increasing BzATP concentrations. ( B ) Dose–response curve of EtBr uptake versus log [BzATP], (EC50 = 7.61 ± 1.14 μM, n = 4). ( C ) Representative histograms of EtBr uptake in HEK293 cells expressing P2X7 variants: basal (blue), 60 μM BzATP for 20 min (yellow), and Triton X-100 (red, positive control). ( D ) Fold change in FL2 fluorescence relative to baseline at 0, 15, and 20 min. Symbols: ⏺ HEK293, ◯ P2X7A, ▲ P2X7B, ▼ P2X7∆N, ◆ P2X7LOCHF, □ with dash line P2X7DN. Inset Triton X-100 positive control. Bars = mean ± S.E.M. of 6 experiments. * = p < 0.05.
