TL;DR: It is reported that metastatic melanomas release extracellular vesicles, mostly in the form of exosomes, that carry PD-L1 on their surface, suggesting a mechanism by which tumours could evade the immunesystem, and the potential application ofExosomal PD- L1 to monitor patient responses to checkpoint therapies.

TL;DR: A resistance program expressed by malignant cells that is associated with T cell exclusion and immune evasion is identified, and this study provides a high-resolution landscape of ICI-resistant cell states, identifies clinically predictive signatures, and suggests new therapeutic strategies to overcome immunotherapy resistance.

TL;DR: IMPRES is a predictor of ICB response in melanoma which encompasses 15 pairwise transcriptomics relations between immune checkpoint genes and achieves an overall accuracy of AUC = 0.83, outperforming existing predictors and capturing almost all true responders while misclassifying less than half of the nonresponders.

TL;DR: Using tumor biopsies from BRAF(V600E) melanoma patients treated either with BRAFi or with combined BRAF and MEK inhibition, it is found that BRAFi-resistant tumors had increased levels of autophagy compared with baseline and a rationale for combination approaches targeting this resistance pathway is provided.

TL;DR: Using mouse melanoma models, it is reported that CD8+ TILs enhance peroxisome proliferator-activated receptor (PPAR)-α signaling and catabolism of fatty acids (FAs) when simultaneously subjected to hypoglycemia and hypoxia.
