Article Title: IFITM1 inhibits Henipavirus membrane fusion by trapping ephrinB2 receptors in fusion-unfavorable membrane nanodomains

doi: 10.64898/2026.05.06.723334

Figure Lengend Snippet: The role of endogenous IFITMs in NiV and HeV pseudovirus entry into human endothelial and epithelial cells. The endogenous IFITMs mRNA levels in HuMEC ( a-c ) and HEK293T cells ( g-i ). Cells were transfected with siRNAs targeting IFITM proteins and scrambled siRNA (NC). IFN-α2b was used to stimulate the expression of IFITM proteins. The mRNA expression levels were detected using qPCR and normalized to that of NC at the untreated condition (-IFN-α). d and j , endogenous IFITM1,2,3 proteins expression in HuMEC ( d ) and HEK293T cells ( j ) upon siRNA knockdown analyzed by Western Blot. IFITMs were detected by anti-IFITM antibodies, and GAPDH was a loading control. The entry of NiV/VSV pp and HeV/VSV pp to HuMEC ( e and f ) and HEK293T cells ( k and l ). NiV and HeV glycoproteins were pseudotyped to VSV particles in which the VSV-G gene was replaced with the Renilla luciferase gene. Virus entry was measured by luminescence intensity and normalized to that of scrambled siRNA at the untreated condition (NC, −IFN-α). Virus entry levels in siRNA-transfected cells were compared with those transfected with scrambled siRNA (NC) under respective −IFN-α and +IFN-α conditions. Virus entry in IFN-α–treated cells (+IFN-α) was further compared with that in resting cells (−IFN-α) and labeled with a bracket. Bars represent means ± SEM. Results from at least 3 independent experiments are shown. p values were obtained using one-way analysis of variance (ANOVA) with post hoc correction (nonsignificant [ns], p > 0.05; *, p ≤ 0.05; **, p ≤ 0.01; ***, p ≤ 0.001; ****, p ≤ 0.0001).
