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.

The key takeaway is captured in this sentence from our paper:

"Cataloging proteome-wide PPIs is more than mere stamp collecting—it is a critical step in unraveling the intricate complexity of biological life."

ICE is no longer immigration enforcement. It’s a sprawling secret police with a budget bigger than some nations’ armies. No oversight. Questionable training. Just masks, unmarked vans, and executive authority. If you think this stops at the border, you’re not paying attention.
