Article Title: The immune regulation and signaling transduction of FAM134B-mediated endoplasmic reticulum-phagy in ferroptosis of dendritic cells after sepsis
doi: 10.1016/j.jare.2025.07.058
Figure Lengend Snippet: FAM134B-mediated ER-phagy downregulates sepsis-induced ferroptosis to protect the immune response of DCs. Two types of mice were adopted the severe CLP. Mice in the control group were defined as a sham operation. A. The percentage of co-stimulatory phenotypes expressed on DCs was measured by flow cytometry. B. DCs from hemophthalmia of CLP mice were cocultured with CD4 + T cells stained with Con A, and then T-cell proliferation induced by DCs was measured by flow cytometry. C. The release of inflammatory cytokines reflecting the degree of DC maturity and secretion was detected by ELISA after CLP. D. The survival rates of WT mice (n = 11) and FAM134B -/- mice (n = 12) were monitored at the indicated time points. E-G. The conditional knockout of FAM134B targeted for splenic DC in mouse (CD11c cre FAM134B fl/fl ) was structured and then underwent CLP procedure. DCs immune functions was measured by Flow Cytometry and survival rates of septic mice were analyzed. Data from three independent experiments were exhibited as the mean ± SD (n = 3 per group). Statistical significance: *P < 0.05, **P < 0.01, ***P < 0.001 vs. the WT-Sham group; # P < 0.05, ## P < 0.01, ### P < 0.001 vs. the FAM134B -/- -Sham group; & P < 0.05, && P < 0.01, &&& P < 0.001 as the FAM134B -/- -CLP group vs. the WT-CLP group.
