Cells undergoing immunogenic death emit danger signals which facilitate anti-tumor immune responses. Although pathways leading to immunogenic cell death are not fully understood; oxidative stress is considered to be part of the underlying mechanism. Here; we studied the interaction between dielectric barrier discharge plasma and cancer cells for oxidative stress-mediated immunogenic cell death. We assessed changes to the intracellular oxidative environment after plasma treatment and correlated it to emission of two danger signals: surface-exposed calreticulin and secreted adenosine triphosphate. Plasma-generated reactive oxygen and charged species were recognized as the major effectors of immunogenic cell death. Chemical attenuators of intracellular reactive oxygen species successfully abrogated oxidative stress following plasma treatment and modulated the emission of surface-exposed calreticulin. -

Its yearling weight and carcass traits (backfat thickness, carcass weight, eye muscle area, and marbling score) are economically important for the selection of young and proven bulls. In recent decades, the advent of high throughput genotyping technologies has made it possible to perform genome-wide association studies (GWAS) for the detection of genomic regions associated with traits of economic interest in different species. In this study, we conducted a weighted single-step genome-wide association study which combines all genotypes, phenotypes and pedigree data in one step (ssGBLUP). It allows for the use of all SNPs simultaneously along with all phenotypes from genotyped and ungenotyped animals. Our results revealed 33 relevant genomic regions related to the traits of interest. -

ATP-Binding and Hydrolysis in Inflammasome Activation

MacDonald * Department of Biochemistry & Molecular Biology, Cumming School of Medicine, University of Calgary, 3280 Hospital Drive NW, Calgary, AB T2N 4Z6, Canada; [email protected] (C.F.S.); [email protected] (B.K.Z.) * Correspondence: [email protected]; Tel.: +1-403-210-8433 Academic Editor: Massimo Bertinaria Received: 15 September 2020; Accepted: 3 October 2020; Published: 7 October 2020 Abstract: The prototypical model for NOD-like receptor (NLR) inflammasome assembly includes nucleotide-dependent activation of the NLR downstream of pathogen- or danger-associated molecular pattern (PAMP or DAMP) recognition, followed by nucleation of hetero-oligomeric platforms that lie upstream of inflammatory responses associated with innate immunity. As members of the STAND ATPases, the NLRs are generally thought to share a similar model of ATP-dependent activation and effect. However, recent observations have challenged this paradigm to reveal novel and complex biochemical processes to discern NLRs from other STAND proteins. In this review, we highlight past findings that identify the regulatory importance of conserved ATP-binding and hydrolysis motifs within the nucleotide-binding NACHT domain of NLRs and explore recent breakthroughs that generate connections between NLR protein structure and function. Indeed, newly deposited NLR structures for NLRC4 and NLRP3 have provided unique perspectives on the ATP-dependency of inflammasome activation. Novel molecular dynamic simulations of NLRP3 examined the active site of ADP- and ATP-bound models. The findings support distinctions in nucleotide-binding domain topology with occupancy of ATP or ADP that are in turn disseminated on to the global protein structure. -
Stress-Induced Inflammation Evoked by Immunogenic Cell Death Is

Verhelst 3,12 and Patrizia Agostinis 1,2 © The Author(s) 2021 Mounting evidence indicates that immunogenic therapies engaging the unfolded protein response (UPR) following endoplasmic reticulum (ER) stress favor proficient cancer cell-immune interactions, by stimulating the release of immunomodulatory/ proinflammatory factors by stressed or dying cancer cells. UPR-driven transcription of proinflammatory cytokines/chemokines exert beneficial or detrimental effects on tumor growth and antitumor immunity, but the cell-autonomous machinery governing the cancer cell inflammatory output in response to immunogenic therapies remains poorly defined. Here, we profiled the transcriptome of cancer cells responding to immunogenic or weakly immunogenic treatments. Bioinformatics-driven pathway analysis indicated that immunogenic treatments instigated a NF-κB/AP-1-inflammatory stress response, which dissociated from both cell death and UPR. This stress-induced inflammation was specifically abolished by the IRE1α-kinase inhibitor KIRA6. Supernatants from immunogenic chemotherapy and KIRA6 co-treated cancer cells were deprived of proinflammatory/chemoattractant factors and failed to mobilize neutrophils and induce dendritic cell maturation. Furthermore, KIRA6 significantly reduced the in vivo vaccination potential of dying cancer cells responding to immunogenic chemotherapy. Mechanistically, we found that the anti-inflammatory effect of KIRA6 was still effective in IRE1α-deficient cells, indicating a hitherto unknown off-target effector of this IRE1α-kinase inhibitor. -

A Role for the Nlr Family Members Nlrc4 and Nlrp3 in Astrocytic Inflammasome Activation and Astrogliosis
A ROLE FOR THE NLR FAMILY MEMBERS NLRC4 AND NLRP3 IN ASTROCYTIC INFLAMMASOME ACTIVATION AND ASTROGLIOSIS Leslie C. Freeman A dissertation submitted to the faculty of the University of North Carolina at Chapel Hill in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Curriculum of Genetics and Molecular Biology. Chapel Hill 2016 Approved by: Jenny P. Y. Ting Glenn K. Matsushima Beverly H. Koller Silva S. Markovic-Plese Pauline. Kay Lund ©2016 Leslie C. Freeman ALL RIGHTS RESERVED ii ABSTRACT Leslie C. Freeman: A Role for the NLR Family Members NLRC4 and NLRP3 in Astrocytic Inflammasome Activation and Astrogliosis (Under the direction of Jenny P.Y. Ting) The inflammasome is implicated in many inflammatory diseases but has been primarily studied in the macrophage-myeloid lineage. Here we demonstrate a physiologic role for nucleotide-binding domain, leucine-rich repeat, CARD domain containing 4 (NLRC4) in brain astrocytes. NLRC4 has been primarily studied in the context of gram-negative bacteria, where it is required for the maturation of pro-caspase-1 to active caspase-1. We show the heightened expression of NLRC4 protein in astrocytes in a cuprizone model of neuroinflammation and demyelination as well as human multiple sclerotic brains. Similar to macrophages, NLRC4 in astrocytes is required for inflammasome activation by its known agonist, flagellin. However, NLRC4 in astrocytes also mediate inflammasome activation in response to lysophosphatidylcholine (LPC), an inflammatory molecule associated with neurologic disorders. In addition to NLRC4, astrocytic NLRP3 is required for inflammasome activation by LPC. Two biochemical assays show the interaction of NLRC4 with NLRP3, suggesting the possibility of a NLRC4-NLRP3 co-inflammasome. -

INVITED REVIEW Mechanisms of Gasdermin family members in inflammasome signaling and cell death Shouya Feng,* Daniel Fox,* Si Ming Man Department of Immunology and Infectious Disease, The John Curtin School of Medical Research, The Australian National University, Canberra, Australia. * S.F. and D.F. equally contributed to this work Correspondence to Si Ming Man: Department of Immunology and Infectious Disease, The John Curtin School of Medical Research, The Australian National University, Canberra, 2601, Australia. [email protected] 1 Abstract The Gasdermin (GSDM) family consists of Gasdermin A (GSDMA), Gasdermin B (GSDMB), Gasdermin C (GSDMC), Gasdermin D (GSDMD), Gasdermin E (GSDME) and Pejvakin (PJVK). GSDMD is activated by inflammasome-associated inflammatory caspases. Cleavage of GSDMD by human or mouse caspase-1, human caspase-4, human caspase-5, and mouse caspase-11, liberates the N-terminal effector domain from the C-terminal inhibitory domain. The N-terminal domain oligomerizes in the cell membrane and forms a pore of 10-16 nm in diameter, through which substrates of a smaller diameter, such as interleukin (IL)-1β and IL- 18, are secreted. The increasing abundance of membrane pores ultimately leads to membrane rupture and pyroptosis, releasing the entire cellular content. Other than GSDMD, the N-terminal domain of all GSDMs, with the exception of PJVK, have the ability to form pores. There is evidence to suggest that GSDMB and GSDME are cleaved by apoptotic caspases. Here, we review the mechanistic functions of GSDM proteins with respect to their expression and signaling profile in the cell, with more focused discussions on inflammasome activation and cell death.
