We used our new ivRIC method to map host proteins inside HIV-1 particles, finding 100+ proteins that the virus hijacks to boost infection. This project has a long history, spanning from pre-COVID to now! Driven by Manuel Garcia-Moreno and led by @alf-castello.bsky.social tinyurl.com/54vb842w

Incorporation of genome-bound cellular proteins into HIV-1 particles regulates viral infection
Does HIV-1 package host proteins that promote infection? Using in virion RNA interactome capture, Garcia-Moreno et al. mapped human proteins bound to the viral genome inside virions. They identified o...

Alphavirus infection triggers selective cytoplasmic translocation of nuclear RBPs with moonlighting antiviral roles
Kamel et al. apply complementary approaches to elucidate the composition of Sindbis virus ribonucleoproteins. They identified a subset of nuclear proteins that selectively translocate to the cytoplasm, interact with viral RNA, and suppress virus infection. Among them, U2 snRNP emerges as a ribonucleoprotein complex with moonlighting antiviral activity.
