Identifying influential spreaders based on improving communication transmission model and network structure.
Zhang S, Sun Z, Wang G, Hu H, Wang F, Sun X. Zhang S, et al. Sci Rep. 2025 Mar 18;15(1):9380. doi: 10.1038/s41598-025-93387-6. Sci Rep. 2025. PMID: 40102538 Free PMC article.
This method not only considers a node's own location and importance, but also the proximity of its neighbors to the target node within two hops. Through extensive experimentation, we demonstrate that our algorithm outperforms representative methods proposed in recent years …

SARS-CoV-2 ORF3a blocks lysosomal cholesterol egress by disrupting VPS39-regulated NPC2 trafficking and BMP metabolism.
Goodson BA, Vazquez VM, Doyle A, Kolaczkowski OM, Liu R, Jia J, Ishida M, Wang H, Han X, Ye C, Kell AM, Bradfute SB, Lemus MR, Pu J. Goodson BA, et al. bioRxiv [Preprint]. 2025 Sep 20:2024.11.13.623299. doi: 10.1101/2024.11.13.623299. bioRxiv. 2025. PMID: 39605369 Free PMC article. Preprint.
Cholesterol homeostasis relies on lysosomes, which release free cholesterol from degraded lipids. We show that SARS-CoV-2 blocks lysosomal cholesterol export through its protein ORF3a. ORF3a binds the HOPS subunit VPS39, and disrupting this interaction …

Myelin basic protein antagonizes the SARS-CoV-2 protein ORF3a-induced autophagy inhibition.
Saratov GA, Belogurov AA Jr, Kudriaeva AA. Saratov GA, et al. Biochimie. 2024 Oct;225:1-9. doi: 10.1016/j.biochi.2024.04.011. Epub 2024 May 3. Biochimie. 2024. PMID: 38703943
Inhibition of autophagy is one of the hallmarks of the SARS-CoV-2 infection. Recently it was reported that SARS-CoV-2 protein ORF3a inhibits fusion of autophagosomes with lysosomes via interaction with VPS39 thus preventing binding of hom …
