Abstract:
Abstract Ovarian cancer is a complex heterogeneous disease with various subtypes and diverse molecular mechanisms of pathogenesis. Among different forms, epithelial ovarian cancer is the most common, representing up to 90% of total reported cases. Due to the lack of early diagnostic tools, the prognosis is mainly poor, as most cases are typically identified in advanced stages. Thus, a more thorough understanding of the inherent complexities of the disease, in terms of its biochemical etiology, will allow for identification of specific molecular and genetic profiles that could lead to more effe

Abstract:
Abstract c-di-GAMP was first identified in bacteria to promote colonization, while mammalian 2’3’-cGAMP is synthesized by cGAS to activate STING for innate immune stimulation. However, 2’3’-cGAMP function beyond innate immunity remains elusive. Here, we report 2’3’-cGAMP promotes cell migration independent of innate immunity. 2’3’-cGAMP interactome analysis identifies the small GTPase Rab18 as a 2’3’-cGAMP binding partner and effector in cell migration control. Mechanistically, 2’3’-cGAMP binds Rab18 to facilitate GTP loading and subsequent Rab18 activation, which further promotes FosB transcr

Abstract:
Abstract HIV infection abrogates adaptive immunity by the depletion of CD4 T cells. However, innate immune defense mechanisms against HIV is largely unknown. Here we show that pseudotyped HIV can infect human and mouse cell lines, leading to the production of interferons and other antiviral cytokines. Activation of innate immunity by HIV requires viral cDNA synthesis but not cDNA integration. We show that retrotranscribed HIV cDNA is sensed by the cytosolic DNA sensor cGAS, which then produces the second messenger 2'3'cGAMP to activate the adaptor STING. Importantly, wild type HIV also trigger

Abstract:
BackgroundAlthough Immune checkpoint inhibitors (ICI)-targeting therapies have revolutionized the treatment of cancer, several tumors do not respond to those therapies. Preclinical and clinical evidences suggest that STING is a promising target to improve the immunogenicity of tumors, turning them responsive to ICI, and enhancing anti-tumor response. DMXAA failed to show efficacy in clinical trials, despite its encouraging anti-tumor response in preclinical phase, highlighting the need of accurate translational preclinical models. On top of the specificity barrier reported for STING-targeting

Abstract:
The tumour microenvironment is composed of extracellular matrix and non-mutated cells supporting tumour growth and development. Tumour-associated macrophages are among the most abundant immune cells in the microenvironment. Studies of the innate immune compartment in the bone marrow of patients with acute myeloid leukaemia (AML) reveal a shift toward a tumour-supportive M2-polarised macrophage (Weinhäuser et al., 2023). Furthermore, previous work by our group has shown that AML drives activation of the stimulator of interferon genes (STING) pathway in macrophages in the AML bone marrow microen

Abstract:
The initiation and proliferation of acute myeloid leukaemia (AML) is in part regulated by the bone marrow microenvironment. Previous work by our group has shown that the stimulator of interferon genes (STING) pathway is activated in macrophages in the AML bone marrow microenvironment (Moore et al., 2022) . We found that AML-derived mitochondrial damage-associated molecular patterns were processed by bone marrow macrophages (BMMs) via LC3-associated phagocytosis (LAP). Furthermore, activation of STING resulted in a suppression of AML growth through an LAP dependent mechanism. Here we have inves

Abstract:
Multiple myeloma (MM) is a multi-step malignancy arising from the clonal proliferation of antibody- secreting cancerous plasma cells in the bone marrow. The progression of the disease, from the benign condition known as monoclonal gammopathy of undetermined significance (MGUS) to frank MM, is in part due to the gradual loss of immunosurveillance caused by pathological alterations of the bone marrow microenvironment, which affect most cell populations, including mesenchymal stromal cells (BMSCs) and Natural Killer (NK) cells. A promising frontier in cancer immunotherapy is
