Figure Lengend Snippet: Fig. 7 | PGE2 enhances prion neurotoxicity mainly through the EP4 receptor (Ptger4). a,b, Live-cell imaging (a) and quantitative analysis (b) of chronically prion-infected HovS cells expressing control (Ctrl) transgene or one of the four PGE2 receptors (Ptger1–4). Effects of PGE2 treatment on prion-induced cell toxicity were measured with the ratio of GFP signals under the PGE2 condition against the DMSO condition; n = 4 independent experiments. Data are presented as mean ± s.e.m. One-way ANOVA with Benjamini–Hochberg FDR adjustment for multiple comparisons: P < 0.0001 (Ptger1 versus Ctrl); P = 0.2246 (Ptger2 versus Ctrl); P = 0.3351 (Ptger3 versus Ctrl); P < 0.0001 (Ptger4 versus Ctrl). c, Immunofluorescence of NeuN, Map2 and Tau showing cellular damage of prion- infected primary neurons treated with different concentrations of Ptger4 agonist L902688. d, Quantification of neuronal density as well as Map2-positive and Tau positive areas shown in c; n = 6 independent experiments. Data are presented as
