Specialized RNA decay fine-tunes monogenic antigen expression in Trypanosoma brucei
Nature Microbiology, Published online: 30 March 2026; doi:10.1038/s41564-026-02289-4To evade the immune system, Trypanosoma brucei relies on a specialized ‘expression site body’. Protein condensates within this nuclear compartment modulate expression of virulence genes via a targeted RNA decay mechanism.
