🚨Paper alert 🚨 Our latest research is out in @Nature! We reveal a surprising new role for the proteasome in innate immunity: generating antimicrobial peptides that can directly disrupt bacterial membranes. 🦠⚡ @WeizmannScience @Sys_Immunology.🔗 .🧵👇.

Thank you for this amazing highlight of our work 🙏🙏🙏.
Top 5 advances in medicine this week (🧵). 1. An untapped treasure trove of antibiotics . The proteasome breaks down proteins that are no longer needed, but it turns out that some of the peptides it produces are repurposed as antibiotics. The top hit is a peptide derived from a

4/ We hope these findings contribute to a better understanding of innate immunity, and open up exciting possibilities for developing new therapeutic strategies against infections, particularly in the face of rising antibiotic resistance.🔬✨.

3/ Using in silico prediction, we identified hundreds of thousands of potential proteasome-derived defense peptides (PDDPs)—an untapped reservoir of natural antimicrobials.

2/ Infection triggers shifts in proteasome composition & function, enhancing its antimicrobial activity. This suggests a built-in defense mechanism beyond adaptive immunity.

1/ For decades, proteasome-derived peptides were mainly linked to antigen presentation. But we found they also act as innate immune effectors—produced both constitutively & in response to infection.
