Abstract The paradigm of non-small cell lung cancer (NSCLC) treatment has been profoundly influenced by the development immune checkpoint inhibitors (ICI), but range clinical responses observed among patients poses significant challenges. To date, analyses tumor biopsies are only parameter used to guide prognosis ICI therapy. Tumor biopsies, however, often difficult obtain and tissue-based biomarkers limited intratumoral heterogeneity temporal variability. In response, there a growing emphasis on “liquid biopsy”‒ derived biomarkers, which offer minimally invasive means dynamically monitor status NSCLC either before and/or during course treatment. Here we review studies in multiple blood-based encompassing circulating soluble analytes, subsets, DNA, mutational burden, cells have shown promising associations with response These investigations unveiled compelling correlations between peripheral both therapy patient outcomes, include rates, progression-free survival, overall survival.

Upon T-cell receptor stimulation, the Programmed cell Death-1 (PD-1) expressed on T-cells can interact with its ligand PD-L1 at surface of cancer cells or antigen-presenting cells. Monoclonal antibodies targeting PD-1 are routinely used for treatment cancers, but their clinical efficacy varies largely across variety tumor types. A part variability is linked to existence several forms PD-L1, either plasma membrane (mPD-L1), secreted cellular exosomes (exoPD-L1), in nuclei (nPD-L1), as a circulating, soluble protein (sPD-L1).

Abstract Current programmed death‐1 ligand (PD‐L1)‐based therapy focuses on local tumors. However, circulating exosomal PD‐L1 possesses inherent anti‐PD‐L1 blockade resistance and dominates tumor metastasis, playing a critical role in systemic immunosuppression. Therefore, the efficacy of immune checkpoint depends simultaneously decreasing tumoral PD‐L1. such therapeutic platforms have never been reported so far. Herein, checkpoint‐regulatable niche created by an injectable hydrogel is to reprogram both exosomes. Oxidized sodium alginate‐armored membrane vesicle (O‐TMV) as gelator, with Ca 2+ channel inhibitor dimethyl amiloride (DMA) cyclin‐dependent kinase 5 (Cdk5) roscovitine formed (O‐TMV@DR) vivo, work antigen depot create niche.
