Figure 1. TRAIL induces MR clustering in mouse CAECs via DR4 receptor.
(A) Representative confocal images showing TRAIL induced clustering of MR markers ganglioside GM1, which were detected by cholera toxin subunit B (CTXB). (B) Summarized data showing the dose-dependent effect of TRAIL (0–100 ng/ml) on MR clustering in Smpd1+/+ CAECs (n=6). (C) Confocal microscopy of Smpd1+/+ CAECs revealed a co-localization of DR4 but not DR5 with MR clusters upon TRAIL stimulation. (D) Summarized data showing the co-localization between MRs and DR4 or DR5 in mouse Smpd1+/+ CAECs. *P < 0.05 vs. control (n=6).
