Resistance to PD1 blockade in the absence of metalloprotease-mediated LAG3 shedding

ABSTRACT: Mechanisms of resistance to cancer immunotherapy remain poorly understood. Lymphocyte Activation Gene-3 (LAG3) signaling is regulated by A Disintegrin And Metalloprotease-10 (ADAM10) and ADAM17-mediated cell surface shedding. We developed and utilized mutant mice expressing a metalloprotease-resistance version of LAG3 that can be selectively expressed in T cell subsets. We sorted live T cells from tumors of mice bearing MC38 tumors following 3 treatments with either anti-PD1 or IgG control, and performed single-cell RNAseq using 10X 3' v2 reagents.

Expression data from kidneys of diabetic WT and T3-/- mice

Project description:Activation of A Disintegrin and A Metalloprotease Domain17 (ADAM17) is involved in nephropathy, but the role of this metalloprotease and its inhibitor TIMP3 in diabetic kidney disease is unclear. We used microarray profiling to find genes differentially expressed in the 2 genotypes which could explain the more severe diabetic kidney disease features observed in T3-/- mice compared to the WT littermates. Total RNA was extracted from 3 WT and 3 Timp3-/- diabetic kidneys

Degradome of soluble ADAM10 and ADAM17 metalloproteases

Project description:Disintegrin and metalloproteinases ADAM10 and ADAM17 can release the extracellular region of a variety of membrane-bound proteins including cytokines, adhesion molecules, growth factors and receptors, important for many biological functions (ectodomain shedding).. So far, substrate identification for ADAM10 and ADAM17 focused exclusively on their membrane-anchored forms and their function as sheddases. With ADAM8 we now describe the first protease capable of releasing the ADAM17 ectodomain. Based on these findings, we investigated whether the soluble ectodomains of ADAM10 and ADAM17 still exhibit shedding activity and to determine their soluble protein substrate pool . To address this, a mass spectrometry-based N-terminomics approach (TAILS) was used to identify potential targets of soluble ADAM10 and ADAM17 (sADAM10/17) within the secretome of the murine cardiomyocyte cell line HL-1. We identified almost 140 protein cleavage events in total and 45 common substrates for both sADAM10 and sADAM17. Further in-vitro studies confirmed fibronectin, cystatin C, sN-cadherin, PCPE-1 as well as sAPP as direct substrates of soluble ADAM10 and/or ADAM17. Overall, we present the first degradome study for sADAM10 and sADAM17, thereby introducing a new regulation mode of the proteolytic activity of these essential proteases within the protease web.

Targeting cardiomyocyte ADAM10 ectodomain shedding promotes survival early after myocardial infarction

Project description:Myocardial infarction (MI) contributes to cardiac mortality and morbidity. After myocardial infarction the innate immune response is pivotal in clearing of tissue debris as well as scar formation, but exaggerated cytokine and chemokine secretion with subsequent leukocyte infiltration also leads to further tissue damage. Post-translational regulation of cytokine / chemokine signaling occurs via ectodomain shedding through a disintegrin and metalloproteases (ADAMs). Here, we address the value of targeting a previously unknown ADAM10 / CX3CL1 axis in the regulation of neutrophil recruitment early after MI. We show that myocardial ADAM10 is distinctly upregulated in biopsies from patients with ischemia-driven cardiomyopathy and correlates with heart failure progression. Intriguingly, upon MI in mice, pharmacological treatment with the ADAM10 inhibitionor GI254023X as well as genetic cardiomycyte-specific ADAM10 deletion improves survival with markedly enhanced heart function and reduced scar size. Mechanistically, this is driven by abolished ADAM10-mediated CX3CL1 ectodomain shedding followed by diminished IL-1β-dependent inflammation, reduced neutrophil bone marrow egress as well as myocardial tissue infiltration. Genetic cardiomycyte-specific ADAM10 deletion confirmes the small-molecule data and leads to improved cardiac function and reduction in inflammatory markers after ischemic myocardial injury. Thus, our data shows a conceptual insight into how acute MI induces chemotactic signaling via ectodomain shedding in cardiomyocytes.

Gene expression profile at single cell level of human TILs treated with PD1-TIM3, PD1-LAG3, anti-PD1 or control isotype.

Project description:Several next-generation cancer immunotherapies are designed to target LAG3 and TIM3 checkpoints, though the molecular and cellular mechanisms by which both receptors operate to mediate their anti-tumour effects are still poorly understood. Here, we examined the phenotypical and transcriptional consequences of treatment with bispecific antibodies (bsAbs), currently being tested in clinical trials, which co-target PD1 and either TIM3 or LAG3, respectively, using scRNAseq.

ADAM17-mediated EGFR ligand shedding directs macrophage-promoted cancer cell invasion

Project description:Macrophages in the tumor microenvironment have a substantial impact on tumor progression. Depending on the signaling environment in the tumor, macrophages can either support or constrain tumor progression. It is therefore of therapeutic interest to identify the tumor-derived factors that control macrophage education. With this aim, we correlated the expression of A Disintegrin and Metalloproteinase (ADAM) proteases, which are key mediators of cell-cell signaling, to the expression of protumorigenic macrophage markers in human cancer cohorts. We identified ADAM17, a sheddase upregulated in many cancer types, as a protein of interest. Depletion of ADAM17 in cancer cell lines reduced the expression of several protumorigenic markers in neighboring macrophages in vitro as well as in mouse models. Moreover, ADAM17–/– educated macrophages demonstrated a reduced ability to induce cancer cell invasion. Using mass spectrometry–based proteomics and ELISA, we identified HB-EGF and AREG, shed by ADAM17 in the cancer cells, as the implicated molecular mediators of macrophage education. Additionally, RNA-Seq and ELISA experiments revealed that ADAM17-dependent HB-EGF ligand release induced the expression and secretion of CXCL chemokines in macrophages, which in turn stimulated cancer cell invasion. In conclusion, we provide evidence that ADAM17 mediates a paracrine EGFR-ligand-chemokine feedback loop, whereby cancer cells hijack macrophages to promote tumor progression.

Project description:We evaluated blood samples from 6 patients with metastatic melanoma treated with anti-LAG3+anti-PD1 (160+480 mg) in a phase I trial (NCT01968109) using single-cell RNA and T cell receptor (TCR) sequencing (scRNA+TCRαβ-seq, 10X 5') combined with other multiomics profiling (flow, cytokine, TCRb-seq) from a larger cohort of 40 patients. This data set include three time points, including baseline, 1 month, and 3 month. The sorting is CD45+.

Resistance to PD1 blockade in the absence of metalloprotease-mediated LAG3 shedding.

Project description:Mechanisms of resistance to cancer immunotherapy remain poorly understood. Lymphocyte activation gene-3 (LAG3) signaling is regulated by a disintegrin and metalloprotease domain-containing protein-10 (ADAM10)- and ADAM17-mediated cell surface shedding. Here, we show that mice expressing a metalloprotease-resistant, noncleavable LAG3 mutant (LAG3NC) are resistant to PD1 blockade and fail to mount an effective antitumor immune response. Expression of LAG3NC intrinsically perturbs CD4+ T conventional cells (Tconvs), limiting their capacity to provide CD8+ T cell help. Furthermore, the translational relevance for these observations is highlighted with an inverse correlation between high LAG3 and low ADAM10 expression on CD4+ Tconvs in the peripheral blood of patients with head and neck squamous cell carcinoma, which corresponded with poor prognosis. This correlation was also observed in a cohort of patients with skin cancers and was associated with increased disease progression after standard-of-care immunotherapy. These data suggest that subtle changes in LAG3 inhibitory receptor signaling can act as a resistance mechanism with a substantive effect on patient responsiveness to immunotherapy.
