Abstract
Junctional adhesion molecule-A (JAM-A), expressed on the surface of myeloid cells, is required for extravasation at sites of inflammation and may also modulate myeloid cell activation. Infiltration of myeloid cells is a common feature of tumors that drives disease progression, but the function of JAM-A in this phenomenon and its impact on tumor-infiltrating myeloid cells is little understood. Here we show that systemic cancer-associated inflammation in mice enhanced JAM-A expression selectively on circulating monocytes in an IL1β-dependent manner. Using myeloid-specific JAM-A-deficient mice, we found that JAM-A was dispensable for recruitment of monocytes and other myeloid cells to tumors, in contrast to its reported role in inflammation. Single-cell RNA sequencing revealed that loss of JAM-A did not influence the transcriptional reprogramming of myeloid cells in the tumor microenvironment. Overall, our results support the notion that cancer-associated inflammation can modulate the phenotype of circulating immune cells, and we demonstrate that tumors can bypass the requirement of JAM-A for myeloid cell recruitment and reprogramming.

Abstract
Agonistic αCD40 therapy has been shown to inhibit cancer progression in only a fraction of patients. Understanding the cancer cell-intrinsic and microenvironmental determinants of αCD40 therapy response is therefore crucial to identify responsive patient populations and to design efficient combinatorial treatments. Here, we show that the therapeutic efficacy of αCD40 in subcutaneous melanoma relies on preexisting, type 1 classical dendritic cell (cDC1)-primed CD8+ T cells. However, after administration of αCD40, cDC1s were dispensable for antitumor efficacy. Instead, the abundance of activated cDCs, potentially derived from cDC2 cells, increased and further activated antitumor CD8+ T cells. Hence, distinct cDC subsets contributed to the induction of αCD40 responses. In contrast, lung carcinomas, characterized by a high abundance of macrophages, were resistant to αCD40 therapy. Combining αCD40 therapy with macrophage depletion led to tumor growth inhibition only in the presence of strong neoantigens. Accordingly, treatment with immunogenic cell death-inducing chemotherapy sensitized lung tumors to αCD40 therapy in subcutaneous and orthotopic settings. These insights into the microenvironmental regulators of response to αCD40 suggest that different tumor types would benefit from different combinations of therapies to optimize the clinical application of CD40 agonists. SIGNIFICANCE This work highlights the temporal roles of different dendritic cell subsets in promoting CD8+ T-cell-driven responses to CD40 agonist therapy in cancer.

Abstract
The combination of radiotherapy (RT) with immunotherapy represents a promising treatment modality for non-small cell lung cancer (NSCLC) patients. As only a minority of patients shows a persistent response today, a spacious optimization window remains to be explored. Previously we showed that fractionated RT can induce a local immunosuppressive profile. Based on the evolving concept of an immunomodulatory role for vagal nerve stimulation (VNS), we tested its therapeutic and immunological effects alone and in combination with fractionated RT in a preclinical-translational study. Lewis lung carcinoma-bearing C57Bl/6 mice were treated with VNS, fractionated RT or the combination while a patient cohort with locally advanced NSCLC receiving concurrent radiochemotherapy (ccRTCT) was enrolled in a clinical trial to receive either sham or effective VNS daily during their 6 weeks of ccRTCT treatment. Preclinically, VNS alone or with RT showed no therapeutic effect yet VNS alone significantly enhanced the activation profile of intratumoral CD8+ T cells by upregulating their IFN-γ and CD137 expression. In the periphery, VNS reduced the RT-mediated rise of splenic, but not blood-derived, regulatory T cells (Treg) and monocytes. In accordance, the serological levels of protumoral CXCL5 next to two Treg-attracting chemokines CCL1 and CCL22 were reduced upon VNS monotherapy. In line with our preclinical findings on the lack of immunological changes in blood circulating immune cells upon VNS, immune monitoring of the peripheral blood of VNS treated NSCLC patients (n=7) did not show any significant changes compared to ccRTCT alone. As our preclinical data do suggest that VNS intensifies the stimulatory profile of the tumor infiltrated CD8+ T cells, this favors further research into non-invasive VNS to optimize current response rates to RT-immunotherapy in lung cancer patients.

Abstract
Abstract
The goal of this study was to investigate the therapeutic potential of targeting regulatory T cells (Treg) through CC motif chemokine receptor 8 (CCR8) and to determine the optimal mode of action for CCR8 targeting molecules to elicit anti-tumor immune response.
Infiltration of high levels of Treg cells in tumors is associated with a poor survival prognosis suggesting that the latter cells restrain effector T cell and overall immune activity in the tumor microenvironment. Modulation and inhibition of Treg cells in the tumor is expected to lead to a reinvigorated immune response against the tumor cells. Since Treg cells are also essential for controlling autoimmunity, modulating regulatory T cell activity is preferably restricted to the tumor microenvironment. CCR8 has been identified as a chemokine receptor expressed specifically on tumor-infiltrating, but not on peripheral Treg cells.
Surrogate molecules targeting mouse CCR8 having distinct modes of action were generated and were tested in different syngeneic tumor mouse models. In the CT26 and MC38 models, anti-CCR8 monotherapy showed a reduction in tumor growth, prolonged survival and tumor stasis in the majority of the mice. Tumor regression was observed in 20-40% of the mice. Combining anti-CCR8 with anti-PD-1 treatment resulted in both models in complete tumor regression in the majority of the mice. Immunophenotyping analysis showed that anti-CCR8 treatment resulted in strongly decreased Treg cell levels in the tumor. In addition, anti-CCR8 monotherapy and anti-PD1 combination therapy lead to an increase of intratumoral CD8 T cell levels resulting in a favorable CD8/Treg cell ratio. Molecules lacking Fc mediated effector function and only blocking the CCL1-CCR8 signaling showed limited or no efficacy in these tumor models, suggesting that the observed anti-tumor effect is due to ADCC/ADCP - mediated Treg cell depletion and not to blocking of CCR8. Moreover, re-challenge of the complete responders (in both MC38 and CT26) resulted in full tumor rejection in the majority of the mice, indicative of a strong immunological memory.
Next to the surrogate molecules, a large set of molecules binding to human CCR8 were identified. Based on human CCR8 binding, CCL1 blocking and in vitro ADCC cell based assay data a final panel of molecules binding to a diverse set of epitopes on human CCR8 have been selected. Final leads are available and are progressing into preclinical development.
Our results demonstrate that targeting CCR8 represents a very attractive and promising method to unleash anti-tumor immune responses in patients.

Abstract
BACKGROUND Modulation and depletion strategies of regulatory T cells (Tregs) constitute valid approaches in antitumor immunotherapy but suffer from severe adverse effects due to their lack of selectivity for the tumor-infiltrating (ti-)Treg population, indicating the need for a ti-Treg specific biomarker. METHODS We employed single-cell RNA-sequencing in a mouse model of non-small cell lung carcinoma (NSCLC) to obtain a comprehensive overview of the tumor-infiltrating T-cell compartment, with a focus on ti-Treg subpopulations. These findings were validated by flow cytometric analysis of both mouse (LLC-OVA, MC38 and B16-OVA) and human (NSCLC and melanoma) tumor samples. We generated two CCR8-specific nanobodies (Nbs) that recognize distinct epitopes on the CCR8 extracellular domain. These Nbs were formulated as tetravalent Nb-Fc fusion proteins for optimal CCR8 binding and blocking, containing either an antibody-dependent cell-mediated cytotoxicity (ADCC)-deficient or an ADCC-prone Fc region. The therapeutic use of these Nb-Fc fusion proteins was evaluated, either as monotherapy or as combination therapy with anti-programmed cell death protein-1 (anti-PD-1), in both the LLC-OVA and MC38 mouse models. RESULTS We were able to discern two ti-Treg populations, one of which is characterized by the unique expression of Ccr8 in conjunction with Treg activation markers. Ccr8 is also expressed by dysfunctional CD4+ and CD8+ T cells, but the CCR8 protein was only prominent on the highly activated and strongly T-cell suppressive ti-Treg subpopulation of mouse and human tumors, with no major CCR8-positivity found on peripheral Tregs. CCR8 expression resulted from TCR-mediated Treg triggering in an NF-κB-dependent fashion, but was not essential for the recruitment, activation nor suppressive capacity of these cells. While treatment of tumor-bearing mice with a blocking ADCC-deficient Nb-Fc did not influence tumor growth, ADCC-prone Nb-Fc elicited antitumor immunity and reduced tumor growth in synergy with anti-PD-1 therapy. Importantly, ADCC-prone Nb-Fc specifically depleted ti-Tregs in a natural killer (NK) cell-dependent fashion without affecting peripheral Tregs. CONCLUSIONS Collectively, our findings highlight the efficacy and safety of targeting CCR8 for the depletion of tumor-promoting ti-Tregs in combination with anti-PD-1 therapy.

Abstract
IL1β is a central mediator of inflammation. Secretion of IL1β typically requires proteolytic maturation by the inflammasome and formation of membrane pores by gasdermin D (GSDMD). Emerging evidence suggests an important role for IL1β in promoting cancer progression in patients, but the underlying mechanisms are ill-defined. Here, we have shown a key role for IL1β in driving tumor progression in two distinct mouse tumor models. Notably, activation of the inflammasome, caspase-8, as well as the pore-forming proteins GSDMD and mixed lineage kinase domain-like protein in the host were dispensable for the release of intratumoral bioactive IL1β. Inflammasome-independent IL1β release promoted systemic neutrophil expansion and fostered accumulation of T-cell-suppressive neutrophils in the tumor. Moreover, IL1β was essential for neutrophil infiltration triggered by antiangiogenic therapy, thereby contributing to treatment-induced immunosuppression. Deletion of IL1β allowed intratumoral accumulation of CD8+ effector T cells that subsequently activated tumor-associated macrophages. Depletion of either CD8+ T cells or macrophages abolished tumor growth inhibition in IL1β-deficient mice, demonstrating a crucial role for CD8+ T-cell-macrophage cross-talk in the antitumor immune response. Overall, these results support a tumor-promoting role for IL1β through establishing an immunosuppressive microenvironment and show that inflammasome activation is not essential for release of this cytokine in tumors.

Abstract
Abstract
Background: Chronic inflammation in the tumor microenvironment (TME) sustained by immune cells has a crucial role both in tumor initiation and progression. One of the central cytokines of inflammation, IL-1β, is produced as a biologically inactive precursor that requires proteolytic processing by caspase-1. Activation of caspase-1 is triggered by the formation of inflammasomes, multiprotein complexes that detect microbial and endogenous danger signals primarily via NOD-like receptors, such as NLRP3 and NLRC4. Biologically active IL-1β is believed to be released through membrane pores formed by gasdermin D during a lytic form of cell death called pyroptosis. Although IL-1β-mediated inflammation has been shown to have a detrimental role in tumor progression, the signaling pathway controlling IL-1β release in the TME and the exact effect of the cytokine on antitumor T-cell responses have not been fully elucidated. A better understanding of how IL-1β release is controlled in tumors will also pave the way towards the therapeutic utilization of small-molecule inhibitors available to target NOD-like receptors and caspase-1. Methods: First, we characterized the impact of IL-1β in the TME by assessing the immune cell composition and vasculature of Lewis lung carcinomas (LLC) and E0771 breast carcinomas in IL-1β-deficient mice using flow cytometry and histologic analysis. Next, we used mice deficient in different inflammasome components, including NLRP3, NLRC4 and caspase-1, to investigate the involvement of these proteins in controlling IL-1β release in LLC and E0771 tumors. Using immunoblots and small-molecule inhibitors, we further characterized the activation of alternative enzymatic pathways and their involvement in IL-1β release by tumor-associated myeloid cells. Finally, we examined the role of pyroptosis and necroptosis in IL-1β release using gasdermin D- and MLKL-deficient mice, respectively. Release of IL-1β was assessed using ELISA and immunoblots. Results: We found that IL-1β secretion was restricted to myeloid cells and promoted tumor progression in mouse models of lung and breast carcinoma. IL-1β deletion abrogated the tumor-induced mobilization of immunosuppressive neutrophils and normalized the tumor vasculature, thereby alleviating hypoxia. Consequently, proliferation of effector T-cells in the TME was enhanced, leading to higher CD4+ and CD8+ T-cell abundance in the absence of IL-1β. We observed that, although the NLRP3 inflammasome was active in tumor-infiltrating myeloid cells, NLRP3 and caspase-1 were not essential for the proteolytic maturation of pro-IL-1β and secretion of biologically active IL-1β in the TME. Inhibition or genetic deletion of caspase-8 reduced inflammasome-independent IL-1β release, indicating that caspase-8 provides an alternative pathway for proteolytic activation and secretion of IL-1β in tumor-infiltrating myeloid cells. Moreover, IL-1β release by tumor-infiltrating myeloid cells was independent of lytic cell death modalities including gasdermin D-mediated pyroptosis and MLKL-mediated necroptosis, suggesting an alternative release mechanism for the cytokine in the TME. Conclusions: Overall, our results demonstrate that tumor-infiltrating myeloid cells are able to release IL-1β independently of inflammasomes. We show that proteolytic maturation of IL-1β via caspase-8 in myeloid cells acts as an important driver of immune suppression in the TME through vascular destabilization, recruitment of immunosuppressive neutrophils and consequential inhibition of antitumor T-cell responses. We also show, that, unlike in autoinflammation, gasdermin D-mediated pyroptosis is not essential for the release of IL-1β in tumors. These results suggest that therapeutic inhibition of inflammasomes or pyroptosis will likely not be beneficial in certain tumor types due to the presence of an alternative caspase-8-mediated IL-1β release pathway in tumor-associated myeloid cells.

Abstract
Therapeutic approaches that engage immune cells to treat cancer are becoming increasingly utilized in the clinics and demonstrated durable clinical benefit in several solid tumor types. Most of the current immunotherapies focus on manipulating T cells, however, the tumor microenvironment (TME) is abundantly infiltrated by a heterogeneous population of tumor-associated myeloid cells, including tumor-associated macrophages (TAMs), tumor-associated dendritic cells (TADCs), tumor-associated neutrophils (TANs), and myeloid-derived suppressor cells (MDSCs). Educated by signals perceived in the TME, these cells often acquire tumor-promoting properties ultimately favoring disease progression. Upon appropriate stimuli, myeloid cells can exhibit cytoxic, phagocytic, and antigen-presenting activities thereby bolstering antitumor immune responses. Thus, depletion, reprogramming or reactivation of myeloid cells to either directly eradicate malignant cells or promote antitumor T-cell responses is an emerging field of interest. In this review, we briefly discuss the tumor-promoting and tumor-suppressive roles of myeloid cells in the TME, and describe potential therapeutic strategies in preclinical and clinical development that aim to target them to further expand the range of current treatment options.

Abstract
The liver is a major target organ for metastasis of both gastrointestinal and extra-gastrointestinal cancers. Due to its frequently inoperable nature, liver metastasis represents a leading cause of cancer-associated death worldwide. In the past years, the pivotal role of the immune system in this process is being increasingly recognised. In particular, the role of the hepatic macrophages, both recruited monocyte-derived macrophages (Mo-Mfs) and tissue-resident Kupffer cells (KCs), has been shown to be more versatile than initially imagined. However, the lack of tools to easily distinguish between these two macrophage populations has hampered the assignment of particular functionalities to specific hepatic macrophage subsets. In this Review, we highlight the most remarkable findings regarding the origin and functions of hepatic macrophage populations, and we provide a detailed description of their distinct roles in the different phases of the liver metastatic process.

Abstract
Tumor-associated macrophages (TAM) are by now established as important regulators of tumor progression by impacting on tumor immunity, angiogenesis, and metastasis. Hence, a multitude of approaches are currently pursued to intervene with TAM's protumor activities, the most advanced of which being a blockade of macrophage-colony stimulating factor (M-CSF)/M-CSF receptor (M-CSFR) signaling. M-CSFR signaling largely impacts on the differentiation of macrophages, including TAM, and hence strongly influences the numbers of these cells in tumors. However, a repolarization of TAM toward a more antitumor phenotype may be more elegant and may yield stronger effects on tumor growth. In this respect, several aspects of TAM behavior could be altered, such as their intratumoral localization, metabolism and regulatory pathways. Intervention strategies could include the use of small molecules but also new generations of biologicals which may complement the current success of immune checkpoint blockers. This review highlights current work on the search for new therapeutic targets in TAM.

Abstract
Dendritic cells (DCs) are specialized APCs present in all tissues, including tumors. They play a major role in orchestrating immune responses and were shown to occur in various functional states in tumors. In this respect, immunogenic tumor-associated DCs (TADCs) are required to initiate and sustain T cell-dependent anti-cancer immunity, whereas regulatory TADCs harbor robust immunosuppressive potential and accelerate malignant growth. Importantly, the heterogeneity of the DC compartment in tumors has been dissected recently in murine and human cancers and was shown to consist of developmentally distinct subsets, including conventional DC (cDC)1, cDC2, and monocyte-derived DCs (Mo-DCs). TADCs constitute an essential target in efforts to generate therapeutic immunity against cancer, and the understanding of the complexity of the TADC heterogeneity might prove important for therapeutic interventions targeted at specific TADC subsets or their precursors. Hence, this review addresses the differential functional specializations of ontogenically distinct TADC subsets.

Abstract
Adsorption of nonionic surfactant on kaolins of different origins was studied. The shape of the isotherm differs only slightly according to the origin of the kaolin, but the amount adsorbed is quite different. The relation between the morphology of the kaolin particles and the shape of the isotherm is not clear. Fluorescence studies show two different solubilization sites for adsorbed pyrene molecules. However, these two environments could not be correlated to the basal and lateral surfaces of the mineral particles.
