Why does RNA undergo glycosylation? Excited to have our paper out. We in collab w/ Ryan Flynn @raflynn5.bsky.social show N-glycans on glycoRNA hide self-RNA from endosomal TLRs promoting silent removal of dead cells. www.nature.com/articles/s41... @uconnresearch.bsky.social @uconnhealth.bsky.social
