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 […]
High regulatory T cells infiltrate within tertiary lymphoid structure restricts response to immune checkpoint blockers in sarcomas

Background The composition of the tumor microenvironment is a key determinant of effective anti-tumor immunity. In sarcomas, the presence of organized B and T cell aggregates, known as tertiary lymphoid structures, has recently been shown to predict response to immune checkpoint blockers. However, only a minority of patients derive clinical benefit from immune checkpoint […]
Development and characterization of a novel anti-PD1 resistant sarcoma mouse model

Soft tissue sarcoma (STS) is known to be resistant to cancer immunotherapy, including prototypical immune checkpoint inhibitors such as anti-PD1 antibodies. It is therefore crucial to develop innovative strategies aimed at improving current clinical benefit. To support this objective, well-characterized sarcoma preclinical models that mimic resistance to immunotherapy are needed. Starting from the anti-PD(L)1-sensitive MCA205 […]
