Characterization of a Novel Compound that Stimulates STING-Mediated Innate Immune Activity in an Allele-Specific Manner

ABSTRACT: A small molecule termed M04 behaves as a novel agonist of human STING. Importantly, we find that the molecule exhibits a differential ability to activate STING based on the allelic variant examined. Furthermore, while M04 is inactive in mice, expression of human STING in mouse cells rescues reactivity to the compound. Using primary human cells in ex vivo assays we were also able to show that M04 is capable of simulating innate responses important for adaptive immune activation such as cytokine secretion, dendritic cell maturation, and T cell cross-priming. Collectively, this work demonstrates the conceivable utility of a novel agonist of human STING both as a research tool for exploring STING biology and as an immune potentiating molecule.

Mouse orthotopic transplantation MSA2 12 samples single cell RNA-Seq

Project description:The goal of this experiment is to examine the effect of STING agonism and interferon signalling in repressing tumour growth through a signalling interplay between cells. Murine tumour organoid lines where orthotopically transplanted into the pancreas of wild-type mice. Tumour bearing mice were treated with the STING agonist MSA-2 or vehicle control. The tumours were dissected and dissociated to single cell for single-cell RNA-sequencing.

STING activation improves T-cell-engaging immunotherapy of acute myeloid leukemia

Project description:T-cell recruiting bispecific antibodies (BsAbs) are in clinical development for relapsed/refractory acute myeloid leukemia (AML). Despite promising response rates, early clinical trials have failed to demonstrate durable responses. Here we investigated whether activation of the innate immune system through stimulator of interferon genes (STING) can enhance target-cell killing by a BsAb targeting CD33 (CD33 BiTE® molecule). Indeed, we show that cytotoxicity against AML mediated by the CD33 BiTE molecule AMG 330 can be greatly enhanced when combined with the STING agonist 2',3'-cyclic GMP–AMP (cGAMP). We used invitro cytotoxicity assays, immunoblotting, transcriptomic analyses, and extensive CRISPR–Cas9 knockout experiments to investigate the enhancing effect of cGAMP on the cytotoxicity of AMG330 against AML. Mechanistically, activated T cells prime target AML cells to STING activation through their effector cytokines interferon-gamma (IFNγ) and tumor necrosis factor (TNF), leading to increased production of typeI interferons and induction of interferon-stimulated genes. This feeds back to the T cells, leading to a further increase in effector cytokines and an overall cytotoxic T-cell phenotype, contributing to the beneficial effect of cGAMP in enhancing AMG330-mediated lysis. As such, we establish a key role for IFNγ in AMG 330-mediated cytotoxicity against AML cells, as well as in rendering AML cells responsive to STING agonism. Here, we propose to improve the efficacy of CD33-targeting BsAbs by combining them with a STING agonist.

Gene expression by cyotosolic DNA stimulation

Project description:STING molecule has been reported to be important adaptor molecule for cytosolic DNA sensing. We investigated gene expression by cytosolic DNA stimulation using bone marrow derived dendritic cells. We comparared gene expression profile between WT and STING knock out BMDCs after cytosolic DNA stimulation. We generated BMDCs by culturing in the presence of GM-CSF. BMDCs were stimulated by purified tumor-cell derived DNA using lipofectamine. After 7 hrs incubation, total RNA was isolated using Rneasy kit (Qiagen) and microarray was performed at genomic core facility in university of Chicago

STING activation promotes robust immune response and NK cell- mediated tumor regression in glioblastoma models

Project description:Immunotherapy has had a tremendous impact on cancer treatment in the past decade, with hitherto unseen responses at advanced and metastatic stages of the disease. However, the aggressive brain tumor glioblastoma (GBM) is highly immunosuppressive and remains largely refractory to current immunotherapeutic approaches. The cGAS-STING cytoplasmic double stranded DNA (dsDNA) sensing pathway has emerged as a next-generation immunotherapy target with potent local immune stimulatory properties. Here, we investigated the status of the STING pathway in GBM and the modulation of the brain tumor microenvironment (TME) with the STING agonist ADU-S100. Our data reveal the presence of STING in human GBM specimens, where it stains strongly in the tumor vasculature. We show that human GBM explants can respond to STING agonist treatment by secretion of inflammatory cytokines. In murine GBM models, we show a profound shift in the tumor immune landscape after STING agonist treatment, with massive infiltration of the tumor-bearing hemisphere with innate immune cells including inflammatory macrophages, neutrophils and NK populations. Treatment of established murine intracranial GL261 and CT-2A tumors by biodegradable ADU-S100-loaded intracranial implants demonstrated a significant increase in survival in both models and long-term survival with immune memory in GL261. Responses to treatment were abolished by NK cell depletion. This study reveals therapeutic potential and deep remodeling of the TME by STING activation in GBM and warrants the further examination of STING agonists alone or in combination with other immunotherapies such as cancer vaccines, CAR T cells, NK therapies or immune checkpoint blockade.

Project description:We employed RNA-seq to study the transcriptomic change in B lymphocytes in response to STING agonist. Transcriptomic analysis of wild type and TMEM173–/– B cells stimulated with STING agonist revealed that the inflammatory response pathway enriched in 3'3'-cGAMP treated WT B cells but lacking in Tmem173-/-B cells comprised of a cluster containing inhibitory regulators, provoking STING signal to evade immune surveillance by inducing an immunosuppressive B cell population.
