Low plasma Arginine level is associated with resistance to immune checkpoint inhibitors in patients with advanced cancer

Background In the era of immuno-oncology, identifying primary resistance mechanisms to immune checkpoint inhibitors remains crucial. A better understanding of these mechanisms may help to identify novel pathways that can be targeted to improve response rates, as well as biomarkers that could support the selection of patients more likely to benefit from cancer immunotherapies. Among […]
