A study from the Weizmann Institute of Science in Israel has revealed an unexpected immune function of proteasomes, the cellular machinery primarily known for protein degradation. The research, published in Nature on 5 March, demonstrates that proteasomes play a direct role in innate immunity by generating antimicrobial peptides (AMPs) that combat bacterial infections. This discovery not only deepens our understanding of cellular defence mechanisms but also opens new avenues for addressing antibiotic resistance.
