| Abstract |
Small extracellular vesicles (sEVs) mediate cell-to-cell communication by carrying RNAs and proteins. Ubiquitin-like 3 (UBL3) functions as a posttranslational modification factor, regulating protein sorting to sEVs. Programmed cell death ligand 1 (PD-L1) binds to programmed cell death 1 (PD-1) on immune cells, suppressing their function. Although immune checkpoint inhibitors, anti-PD-L1 and anti-PD-1 antibodies, have improved cancer treatment, efficacy remains limited (~ 25%). Per recent studies, PD-L1-containing sEVs are elevated in cancer patients, contributing to impaired immunotherapy responses. Herein, we discovered that PD-L1 is modified by UBL3 and that its sorting to sEVs is regulated by UBL3. Furthermore, we found that statins, commonly prescribed for hypercholesterolemia, inhibit UBL3 modification, thereby reducing PD-L1 sorting to sEVs. Among patients with a high tumor proportion score, serum levels of PD-L1-containing sEVs were significantly lower in those using statins. Consistently, bioinformatic analysis revealed that UBL3 and PD-L1 expression levels affect lung cancer survival. Integrating statins into existing combination therapies may therefore offer a promising strategy to enhance immunotherapy efficacy. |
