Confocal Imaging of Double-Stranded RNA and Pattern Recognition Receptors in Negative-Sense RNA Virus Infection

Overview

This study investigates the recognition of double-stranded RNA (dsRNA) produced during RNA virus replication by pattern recognition receptors (PRRs) to induce an innate immune response. The focus is on negative-sense RNA viruses, where the interaction between low-level dsRNA and PRRs is not well understood. A confocal microscopy method has been developed to visualize arenavirus dsRNA and PRRs in individual cells.
