doi: 10.1186/s12964-026-02705-6
Figure Lengend Snippet: TMEM175-mediated endolysosomal alkalinization restricts poxvirus replication. ( A ) A schematic diagram of the regulation pattern of endolysosomal acidification environment. ( B ) GFP fluorescence imaging of CPXV (MOI = 0.05)-infected HeLa cells overexpressing TMEM175 compared with control cells. Plaque assay of supernatant from CPXV-infected HeLa cells overexpressing TMEM175 and control cells. ( C ) Plaque assay and GFP fluorescence imaging of CPXV (MOI = 0.05)-infected Vero cells treated with DCPIB at 2.5 µM and 5 µM, compared with untreated control. ( D ) Plaque assay and GFP fluorescence imaging of CPXV (MOI = 0.05)-infected Vero cells treated with Arachidonic acid (ArA) at 5 µM and 10 µM, compared with untreated control. ( E ) Quantitative analysis of E3L (left), A3L (middle), and D13L (right) mRNA expression levels in VACV-infected cells treated or untreated with DCPIB. mRNA levels were measured at 4, 8, 12, and 24 h post-infection by qRT-PCR. ( F ) Western blotting analysis of VACV protein expression in infected cells treated with DCPIB at 5 µM and 10 µM or left untreated. Protein levels of E3L, WR117, L1R, and D8L were detected at 4, 8, 12, and 24 h post-infection. The mean value was calculated by one‑way ANOVA with Tukey (mean ± SD, n = 3). * P < 0.05, ** P < 0.01, *** P < 0.001
