Riboseq identifies 98 alternative ORFs & sORFs beyond HIV-1's canonical CDSs in CD4⁺ T cells. Huge strides in understanding HIV's coding potential! 🌟 #HIVResearch PMID:39966340, Nat Commun 2025, @NatureComms https://doi.org/10.1038/s41467-025-56773-2 #Medsky #Pharmsky #RNAsky 🧪
Unveiling conserved HIV-1 open reading frames encoding T cell antigens using ribosome profiling | Nature Communications
The development of ribosomal profiling (Riboseq) revealed the immense coding capacity of human and viral genomes. Here, we used Riboseq to delineate the translatome of HIV-1 in infected CD4+ T cells. In addition to canonical viral protein coding sequences (CDSs), we identify 98 alternative open reading frames (ARFs), corresponding to small Open Reading Frames (sORFs) that are distributed across the HIV genome including the UTR regions. Using a database of HIV genomes, we observe that most ARF amino-acid sequences are likely conserved among clade B and C of HIV-1, with 8 ARF-encoded amino-acid sequences being more conserved than the overlapping CDSs. Using T cell-based assays and mass spectrometry-based immunopeptidomics, we demonstrate that ARFs encode viral polypeptides. In the blood of people living with HIV, ARF-derived peptides elicit potent poly-functional T cell responses mediated by both CD4+ and CD8+ T cells. Our discovery expands the list of conserved viral polypeptides that a
