A multiomics framework for high-throughput lncRNA characterization uncovers major immune regulators

ABSTRACT: Long noncoding RNAs (lncRNAs) play crucial roles in eukaryotic biology, yet their functions in the immune system are not fully understood. This study presents a comprehensive resource on the regulation, pathway dependencies, subcellular localizations, and protein interactomes of lncRNAs in immune cells exposed to pathogens. We developed GRADR, a methodology combining gradient profiling and RNA-bound proteome analysis, to map interactomes for all expressed RNAs in a single experiment. Using GRADR and targeted CRISPR multiomics, we identified a network of lncRNAs, including LINC01215, AC022816, and LINC01268 (ROCKI), that influence immunity, mainly through interactions with splicing factors. Our data are compiled into SMyLR, a web interface providing access to our lncRNA regulation and interactome atlas. This resource is expected to significantly advance research into RNA regulation in immunity.

Long noncoding RNAs (lncRNA) are crucial yet underexplored regulators of human immunity. Here we develop GRADR, a method integrating gradient profiling with RNA-binding proteome analysis, to map the protein interactomes of all expressed RNAs in a single experiment to study mechanisms of lncRNA-mediated regulation of human primary macrophages. Applying GRADR alongside CRISPR-multiomics, we reveal a network of NFκB-dependent lncRNAs, including LINC01215, AC022816.1 and ROCKI, which modulate distin ...[more]

Project description:Macrophages are essential for pathogen clearance and to preserve tissue homeostasis, yet the molecular regulators of this equilibrium remain incompletely defined. Here, we identify SAILR, a primate-specific long noncoding RNA (lncRNA), as a critical modulator of macrophage viability under infection conditions. SAILR is induced during monocyte-to-macrophage differentiation, but rapidly downregulated upon bacterial challenge in an NFκB-dependent manner. In both naïve and immune-activated macrophages, SAILR dampens the expression of adhesion, phagocytosis and invasion factors, including SIGLEC1 and MMP7. During Salmonella Typhimurium infection, depletion of SAILR sensitizes macrophages to apoptosis, resulting in loss of intracellular replication niches and reduced bacterial recovery. Conversely, enforced SAILR expression promotes macrophage survival and increases intracellular pathogen burden. Mechanistically, SAILR interacts with the anti-apoptotic adaptor protein 14-3-3β to support macrophage survival. Notably, downregulation of SAILR is mirrored in circulating immune cells from patients with severe COVID-19 and sepsis. Together, our findings position SAILR as a central regulator linking macrophage survival to host-pathogen interaction and disease pathophysiology. Long noncoding RNAs (lncRNAs) are a class of regulatory molecules whose roles in the immune system remain poorly understood. In this study, we identify a human-specific lncRNA named SAILR that modulates the viability of macrophages - immune cells essential for pathogen clearance. SAILR interacts with the adaptor protein 14-3-3β and is rapidly downregulated upon bacterial infection, which sensitizes macrophages to cell death. This may limit the formation of intracellular niches that support pathogen propagation. Reduced SAILR levels in patients suffering from severe infections (sepsis and COVID-19) further suggest clinical relevance. Together, our findings reveal an RNA-based mechanism linking macrophage survival control to host defense and suggest SAILR as a potential diagnostic marker or therapeutic target in infectious and inflammatory diseases.
