Proteasome: An antibiotic arsenal in anti-bacterial innate immunity
The function of the proteasome besides degrading protein remains enigmatic. Goldberg et al. demonstrate that proteasomes can process proteins into antimicrobial peptides (AMPs) to ward off bacterial infection, revealing a new function of proteasomes in innate immunity.

A new #ScienceAdvances study identifies a neuroimmune pathway for treating sepsis, finding that dopamine inhibits expression of a critical regulator of immunometabolism. This suggests that pramipexole, a dopamine agonist, could effectively treat lethal infections. scim.ag/4kfAfrZ

Nivolumab combined with induction chemotherapy and radiotherapy in nasopharyngeal carcinoma: A multicenter phase 2 PLATINUM trial
Xu et al. conduct a single-arm, phase 2 study evaluating the efficacy and safety of nivolumab plus induction chemotherapy and radiotherapy in patients with nasopharyngeal carcinoma. This combination therapy sparing concurrent cisplatin improves failure-free survival compared with a historical benchmark, and has low toxicity and favorable patient-reported tolerability and quality-of-life.

Cell cycle duration determines oncogenic transformation capacity - Nature
Total cell cycle duration is a key hallmark of cancer initiation, and determines whether defects in apoptosis, senescence, immune surveillance, angiogenesis, DNA repair, polarity and proliferation lead to cancer development.
