Microbiota-associated immunotherapy resistance caused by deficient PD-L2 - RGMb signaling.
In a recent paper in Nature, Park et al. propose a mechanism through which intestinal dysbiosis compromises the efficacy of immunotherapy targeting the PD-L1/PD-1 interaction. Dysbiosis may upregulate a pair of checkpoint molecules, i.e. PD-L2 interacting with RGMb. Antibodies targeting PD-L2/RGMb can restore responses to PD-1 blockade in the context of dysbiosis.
期刊介绍：
Tumor immunology explores the natural and therapy-induced recognition of cancers, along with the complex interplay between oncogenesis, inflammation, and immunosurveillance. In response to recent advancements, a new journal, OncoImmunology, is being launched to specifically address tumor immunology. The field has seen significant progress with the clinical demonstration and FDA approval of anticancer immunotherapies. There's also growing evidence suggesting that many current chemotherapeutic agents rely on immune effectors for their efficacy.
While oncologists have historically utilized chemotherapeutic and radiotherapeutic regimens successfully, they may have unwittingly leveraged the immune system's ability to recognize tumor-specific antigens and control cancer growth. Consequently, immunological biomarkers are increasingly crucial for cancer prognosis and predicting chemotherapy efficacy. There's strong support for combining conventional anticancer therapies with immunotherapies. OncoImmunology will welcome high-profile submissions spanning fundamental, translational, and clinical aspects of tumor immunology, including solid and hematological cancers, inflammation, and both innate and acquired immune responses.
