Abstract
The microbiome is a predictor of clinical outcome in patients receiving allogeneic hematopoietic stem cell transplantation (allo-SCT). Microbiota-derived metabolites can modulate these outcomes. How bacteria, fungi and viruses contribute to the production of intestinal metabolites is still unclear. We combined amplicon sequencing, viral metagenomics and targeted metabolomics from stool samples of patients receiving allo-SCT (n = 78) and uncovered a microbiome signature of Lachnospiraceae and Oscillospiraceae and their associated bacteriophages, correlating with the production of immunomodulatory metabolites (IMMs). Moreover, we established the IMM risk index (IMM-RI), which was associated with improved survival and reduced relapse. A high abundance of short-chain fatty acid-biosynthesis pathways, specifically butyric acid via butyryl-coenzyme A (CoA):acetate CoA-transferase (BCoAT, which catalyzes EC 2.8.3.8) was detected in IMM-RI low-risk patients, and virome genome assembly identified two bacteriophages encoding BCoAT as an auxiliary metabolic gene. In conclusion, our study identifies a microbiome signature associated with protective IMMs and provides a rationale for considering metabolite-producing consortia and metabolite formulations as microbiome-based therapies.

Abstract
BACKGROUND Inter-individual differences in response to immune checkpoint inhibitors (ICI) remain a major challenge in cancer treatment. The composition of the gut microbiome has been associated with differential ICI outcome, but the underlying molecular mechanisms remain unclear, and therapeutic modulation challenging. METHODS We established an in vivo model to treat C57Bl/6j mice with the type-I interferon (IFN-I)-modulating, bacterial-derived metabolite desaminotyrosine (DAT) to improve ICI therapy. Broad spectrum antibiotics were used to mimic gut microbial dysbiosis and associated ICI resistance. We utilized genetic mouse models to address the role of host IFN-I in DAT-modulated antitumour immunity. Changes in gut microbiota were assessed using 16S-rRNA sequencing analyses. FINDINGS We found that oral supplementation of mice with the microbial metabolite DAT delays tumour growth and promotes ICI immunotherapy with anti-CTLA-4 or anti-PD-1. DAT-enhanced antitumour immunity was associated with more activated T cells and natural killer cells in the tumour microenvironment and was dependent on host IFN-I signalling. Consistent with this, DAT potently enhanced expansion of antigen-specific T cells following vaccination with an IFN-I-inducing adjuvant. DAT supplementation in mice compensated for the negative effects of broad-spectrum antibiotic-induced dysbiosis on anti-CTLA-4-mediated antitumour immunity. Oral administration of DAT altered the gut microbial composition in mice with increased abundance of bacterial taxa that are associated with beneficial response to ICI immunotherapy. INTERPRETATION We introduce the therapeutic use of an IFN-I-modulating bacterial-derived metabolite to overcome resistance to ICI. This approach is a promising strategy particularly for patients with a history of broad-spectrum antibiotic use and associated loss of gut microbial diversity.

Abstract
Tumor-derived extracellular vesicles (EVs) have been associated with immune evasion and tumor progression. We show that the RNA-sensing receptor RIG-I within tumor cells governs biogenesis and immunomodulatory function of EVs. Cancer-intrinsic RIG-I activation releases EVs, which mediate dendritic cell maturation and T cell antitumor immunity, synergizing with immune checkpoint blockade. Intact RIG-I, autocrine interferon signaling, and the GTPase Rab27a in tumor cells are required for biogenesis of immunostimulatory EVs. Active intrinsic RIG-I signaling governs composition of the tumor EV RNA cargo including small non-coding stimulatory RNAs. High transcriptional activity of EV pathway genes and RIG-I in melanoma samples associate with prolonged patient survival and beneficial response to immunotherapy. EVs generated from human melanoma after RIG-I stimulation induce potent antigen-specific T cell responses. We thus define a molecular pathway that can be targeted in tumors to favorably alter EV immunomodulatory function. We propose "reprogramming" of tumor EVs as a personalized strategy for T cell-mediated cancer immunotherapy.

Abstract
Achieving durable clinical responses to immune checkpoint inhibitors remains a challenge. Here, we demonstrate that immunotherapy with anti-CTLA-4 and its combination with anti-PD-1 rely on tumor cell-intrinsic activation of the cytosolic RNA receptor RIG-I. Mechanistically, tumor cell-intrinsic RIG-I signaling induced caspase-3-mediated tumor cell death, cross-presentation of tumor-associated antigen by CD103+ dendritic cells, subsequent expansion of tumor antigen-specific CD8+ T cells, and their accumulation within the tumor tissue. Consistently, therapeutic targeting of RIG-I with 5'- triphosphorylated RNA in both tumor and nonmalignant host cells potently augmented the efficacy of CTLA-4 checkpoint blockade in several preclinical cancer models. In humans, transcriptome analysis of primary melanoma samples revealed a strong association between high expression of DDX58 (the gene encoding RIG-I), T cell receptor and antigen presentation pathway activity, and prolonged overall survival. Moreover, in patients with melanoma treated with anti-CTLA-4 checkpoint blockade, high DDX58 RIG-I transcriptional activity significantly associated with durable clinical responses. Our data thus identify activation of RIG-I signaling in tumors and their microenvironment as a crucial component for checkpoint inhibitor-mediated immunotherapy of cancer.

Abstract
BACKGROUND/AIMS Endoplasmic reticulum (ER)-resident proteins with a C-terminal KDEL ERretention sequence are captured in the Golgi apparatus by KDEL receptors (KDELRs). The binding of such proteins to these receptors induces their retrograde transport. Nevertheless, some KDEL proteins, such as Protein Disulfide Isomerases (PDIs), are found at the cell surface. PDIs target disulfide bridges in the extracellular domains of proteins, such as integrins or A Disintegrin And Metalloprotease 17 (ADAM17) leading to changes in the structure and function of these molecules. Integrins become activated and ADAM17 inactivated upon disulfide isomerization. The way that PDIs escape from retrograde transport and reach the plasma membrane remains far from clear. Various mechanisms might exist, depending on whether a local cell surface association or a more global secretion is required. METHODS To get a more detailed insight in the transport of PDIs to the cell surface, methods such as cell surface biotinylation, flow cytometric analysis, immunoprecipitation, fluorescence microscopy as well as labeling of cells with fluorescence labled recombinant PDIA6 was performed. RESULTS Here, we show that the C-terminal KDEL ER retention sequence is sufficient to prevent secretion of PDIA6 into the extracellular space but is mandatory for its association with the cell surface. The cell surface trafficking of PDIA1, PDIA3, and PDIA6 is dependent on KDELR1, which travels in a dynamic manner to the cell surface. This transport is assumed to result in PDI cell surface association, which differs from PDI inducible secretion into the extracellular space. Distinct PDIs differ in their trafficking properties. Endogenous KDELR1, detectable at the cell surface, might be involved not only in the transport of cell-surface-associated PDIs, but also in their retrieval and internalization from the extracellular space. CONCLUSION Beside their ER retention motive PDIs travel to the cell surface. Here they target different proteins to render their function. To escape the ER PDIs travel via various pathways. One of them depends on the KDELR1, which can transport its target to the cell surface, where it is to be expected to release its cargo in close vicinity to its target molecules. Hence, the KDEL sequence is needed for cell surface association of PDIs, such as PDIA6.
