RNA editing is a posttranscriptional mechanism that targets changes in transcripts to modulate innate immune responses. We report the role of astrocyte-specific, ADAR1-mediated neuroinflammation Parkinson’s disease (PD). generated human induced pluripotent stem cell–derived astrocytes, neurons and cocultures exposed them small soluble alpha-synuclein aggregates. Oligomeric triggered an inflammatory glial state associated with Toll-like receptor activation, viral responses, cytokine secretion. This reactive resulted loss neurosupportive functions induction neuronal toxicity. Notably, interferon response pathways were activated leading up-regulation isoform switching deaminase enzyme, ADAR1. ADAR1 mediates A-to-I editing, increases observed cells, as well postmortem PD brain. Aberrant, or dysregulated, responses may lead sustained states astrocytes by aggregation, this drive neuroinflammatory cascade Parkinson’s.

Abstract: PANoptosis is a new cell death proposed by Malireddi et al in 2019, which characterized pyroptosis, apoptosis and necroptosis, but cannot be explained any of them alone. The interaction between necroptosis involved PANoptosis. In this review, from the perspective PANoptosis, we focus on relationship key molecules process formation PANoptosome, as well role diseases.

Abstract Receptor-interacting protein kinase 3 (RIPK3), a member of the receptor-interacting (RIPK) family with serine/threonine activity, interacts RIPK1 to generate necrosomes, which trigger caspase-independent programmed necrosis. As vital component RIPK3 plays an indispensable role in necroptosis, is crucial for human life and health. In addition, participates pathological process several infections, aseptic inflammatory diseases, tumors (including tumor-promoting -suppressive activities) by regulating autophagy, cell proliferation, metabolism production chemokines/cytokines. This review summarizes recent research progress regulators signaling pathway discusses potential RIPK3/necroptosis aetiopathogenesis various diseases. An in-depth understanding mechanisms functions may facilitate development novel therapeutic strategies.

Abstract Nucleic acid sensing is involved in viral infections, immune response-related diseases, and therapeutics. Based on the composition of nucleic acids, sensors are defined as DNA or RNA sensors. Pathogen-associated acids recognized by membrane-bound intracellular receptors, known pattern recognition receptors (PRRs), which induce innate immune-mediated antiviral responses. PRR activation tightly regulated to eliminate infections prevent abnormal excessive an essential mechanism tumor immunotherapy gene therapies that target cancer infectious diseases through genetically engineered cells therapeutic acids. supports priming desirable responses during treatment. Recent studies have shown affects efficiency therapy inhibiting translation. Suppression immunity induced small-molecule inhibitors, virus-derived proteins, chemical modifications offers a potential strategy. Herein, we review mechanisms regulation sensing, specifically covering recent advances. Furthermore, summarize discuss research progress regarding different effects efficacy. This study provides insights for application therapy.

Programmed cell death (PCD) is a key mechanism for the study of anticancer drugs and has significant impact on development management cancer. A growing amount data indicates that different kinds PCD, particularly pyroptosis, apoptosis, necroptosis, interact closely. Recent research revealed existence distinct inflammatory PCD modality known as PANoptosis, which controlled by complex PANoptosome complexes built combining elements from pathways. No single route sufficient to explain all physiologic effects seen in PANoptosis. Numerous studies have demonstrated PANoptosis can successfully stop cancer cells growing, proliferating, developing drug resistance. As result, it changed focus targeted therapy. In this review, we outlined molecular processes activation modulation well mechanisms innate immune death. order provide theoretical foundation targeting an anti-cancer target, also highlight PANoptosomes discovered date give overview implications treatment.

Nucleic acids are among the most essential PAMPs (pathogen-associated molecular patterns). Animals have evolved numerous sensors to recognize nucleic and trigger immune signaling against pathogen replication, cellular stress cancer. Many sensor proteins (e.g., cGAS, AIM2, TLR9) signature of infection or responsible for innate response DNA. Remarkably, recent evidence demonstrates that cGAS-like receptors acquire ability sense RNA in some forms life. Compared with nucleic-acid sensing by responses based on various sensors, including RIG-I, MDA5, ADAR1, TLR3/7/8, OAS1, PKR, NLRP1/6, ZBP1, via a broad-spectrum axis. Importantly, new advances brought light potential clinical application targeting these pathways. Here, we highlight latest discoveries field. We also summarize activation regulatory mechanisms RNA-sensing signaling. In addition, discuss how is tightly controlled cells why disruption homeostasis linked disease.

The innate immune system promptly detects and responds to invading pathogens, with a key role played by the recognition of bacterial-derived DNA through pattern receptors. Z-DNA binding protein 1 (ZBP1) functions as sensor inducing type I interferon (IFN) production, responses also inflammatory cell death. ZBP1 interacts cytosolic via its DNA-binding domains, crucial for activation. Brucella abortus is etiologic agent brucellosis in livestock humans, leading significant economic losses public health impact. Despite other sensors that recognize B. DNA, including Toll-like receptor 9 Stimulator genes (STING), here we evaluated participation sensing infection. Using macrophages derived from knockout (KO) mice demonstrated partially contributes IFN-β expression upon infection or transfection. knockdown STING siRNA decreased residual signal elicited infection, demonstrating presence redundant DNA-sensing mechanism driving IFN production. Furthermore, involved signaling IRF-1 expression. Additionally, Unfolded Protein Response (UPR) activation during However, does not influence production proinflammatory mediators, inflammasome it dispensable control bacterial replication macrophages. This study highlights complex interactions components receptors identifies DNA-induced response.

Cell death is a fundamental pathophysiological process in human disease. The discovery of necroptosis, form regulated necrosis that induced by the activation receptors and formation necrosome, represents major breakthrough field cell past decade. Z-DNA-binding protein (ZBP1) an interferon (IFN)-inducing protein, initially reported as double-stranded DNA (dsDNA) sensor, which induces innate inflammatory response. Recently, ZBP1 was identified important sensor necroptosis during virus infection. It connects viral nucleic acid receptor-interacting kinase 3 (RIPK3) via two domains necrosome. Recent studies have also non-viral infections mediates necrotic signal transduction unique mechanism. This review highlights its novel findings provides insight into critical role crosstalk between different types death, may represent new therapeutic option.
