The Expression of NOD2, NLRP3 and NLRC5 and Renal Injury in Anti-Neutrophil Cytoplasmic Antibody-Associated Vasculitis
Wang et al. J Transl Med (2019) 17:197 https://doi.org/10.1186/s12967-019-1949-5 Journal of Translational Medicine RESEARCH Open Access The expression of NOD2, NLRP3 and NLRC5 and renal injury in anti-neutrophil cytoplasmic antibody-associated vasculitis Luo‑Yi Wang1,2,3, Xiao‑Jing Sun1,2,3, Min Chen1,2,3* and Ming‑Hui Zhao1,2,3,4 Abstract Background: Nucleotide‑binding oligomerization domain (NOD)‑like receptors (NLRs) are intracellular sensors of pathogens and molecules from damaged cells to regulate the infammatory response in the innate immune system. Emerging evidences suggested a potential role of NLRs in anti‑neutrophil cytoplasmic antibody (ANCA)‑associated vasculitis (AAV). This study aimed to investigate the expression of nucleotide‑binding oligomerization domain con‑ taining protein 2 (NOD2), NOD‑like receptor family pyrin domain containing 3 (NLRP3) and NOD‑like receptor family CARD domain containing 5 (NLRC5) in kidneys of AAV patients, and further explored their associations with clinical and pathological parameters. Methods: Thirty‑four AAV patients in active stage were recruited. Their renal specimens were processed with immu‑ nohistochemistry to assess the expression of three NLRs, and with double immunofuorescence to detect NLRs on intrinsic and infltrating cells. Analysis of gene expression was also adopted in cultured human podocytes. The associa‑ tions between expression of NLRs and clinicopathological parameters were analyzed. Results: The expression of NOD2, NLRP3 and NLRC5 was signifcantly higher in kidneys from AAV patients than those from normal controls, minimal change disease or class IV lupus nephritis. These NLRs co‑localized with podocytes and infltrating infammatory cells. -
Role of Nlrs in the Regulation of Type I Interferon Signaling, Host Defense and Tolerance to Inflammation
International Journal of Molecular Sciences Review Role of NLRs in the Regulation of Type I Interferon Signaling, Host Defense and Tolerance to Inflammation Ioannis Kienes 1, Tanja Weidl 1, Nora Mirza 1, Mathias Chamaillard 2 and Thomas A. Kufer 1,* 1 Department of Immunology, Institute for Nutritional Medicine, University of Hohenheim, 70599 Stuttgart, Germany; [email protected] (I.K.); [email protected] (T.W.); [email protected] (N.M.) 2 University of Lille, Inserm, U1003, F-59000 Lille, France; [email protected] * Correspondence: [email protected] Abstract: Type I interferon signaling contributes to the development of innate and adaptive immune responses to either viruses, fungi, or bacteria. However, amplitude and timing of the interferon response is of utmost importance for preventing an underwhelming outcome, or tissue damage. While several pathogens evolved strategies for disturbing the quality of interferon signaling, there is growing evidence that this pathway can be regulated by several members of the Nod-like receptor (NLR) family, although the precise mechanism for most of these remains elusive. NLRs consist of a family of about 20 proteins in mammals, which are capable of sensing microbial products as well as endogenous signals related to tissue injury. Here we provide an overview of our current understanding of the function of those NLRs in type I interferon responses with a focus on viral infections. We discuss how NLR-mediated type I interferon regulation can influence the development of auto-immunity and the immune response to infection.

Cytotoxic T Cells Class I- Dependent Lymphocyte Killing by NLRC5 Deficiency Selectively Impairs
The Journal of Immunology NLRC5 Deficiency Selectively Impairs MHC Class I- Dependent Lymphocyte Killing by Cytotoxic T Cells Francesco Staehli,* Kristina Ludigs,* Leonhard X. Heinz,† Queralt Seguı´n-Este´vez,‡ Isabel Ferrero,x Marion Braun,x Kate Schroder,{ Manuele Rebsamen,† Aubry Tardivel,* Chantal Mattmann,* H. Robson MacDonald,x Pedro Romero,x Walter Reith,‡ Greta Guarda,*,1 and Ju¨rg Tschopp*,1,2 Nucleotide-binding oligomerization domain-like receptors (NLRs) are intracellular proteins involved in innate-driven inflamma- tory responses. The function of the family member NLR caspase recruitment domain containing protein 5 (NLRC5) remains a matter of debate, particularly with respect to NF-kB activation, type I IFN, and MHC I expression. To address the role of NLRC5, we generated Nlrc5-deficient mice (Nlrc5D/D). In this article we show that these animals exhibit slightly decreased CD8+ T cell percentages, a phenotype compatible with deregulated MHC I expression. Of interest, NLRC5 ablation only mildly affected MHC I expression on APCs and, accordingly, Nlrc5D/D macrophages efficiently primed CD8+ T cells. In contrast, NLRC5 deficiency dramatically impaired basal expression of MHC I in T, NKT, and NK lymphocytes. NLRC5 was sufficient to induce MHC I expression in a human lymphoid cell line, requiring both caspase recruitment and LRR domains. Moreover, endogenous NLRC5 localized to the nucleus and occupied the proximal promoter region of H-2 genes. Consistent with downregulated MHC I expression, the elimination of Nlrc5D/D lymphocytes by cytotoxic T cells was markedly reduced and, in addition, we observed low NLRC5 expression in several murine and human lymphoid-derived tumor cell lines. -

Results: Overexpression of NLRX1 and NLRC3 results in nonspecific post-transcriptional inhibition of LRAs. Conclusion: LRAs are not a reliable technique to assess the inhibitory function of NLRs.

International Diabetic Federations (IDF) estimates up to 629 million people with DM by the year 2045 worldwide. Nearly 50% of DM patients will show evidence of diabetic-related eye problems. Therapeutic interventions for DR are limited and mostly involve surgical intervention at the late-stages of the disease. The lack of early-stage diagnostic tools and therapies, especially in DR, demands a better understanding of the biological processes involved in the etiology of disease progression. -

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. -

Expression of Specific Inflammasome Gene Modules Stratifies Older

Inflammasomes can drive chronic inflammation in the context of an infectious disease or cellular stress, and they trigger the maturation of interleukin-1b (IL-1b). Here we find that the expression of specific inflammasome gene modules stratifies older individuals into two extremes: those with constitutive expression of IL-1b, nucleotide metabolism dysfunction, elevated oxidative stress, high rates of hypertension and arterial stiffness; and those without constitutive expression of IL-1b, who lack these characteristics. Adenine and N4-acetylcytidine, nucleotide-derived metabolites that are detectable in the blood of the former group, prime and activate the NLRC4 inflammasome, induce the production of IL-1b, activate platelets and neutrophils and elevate blood pressure in mice. In individuals over 85 years of age, the elevated expression of inflammasome gene modules was associated with all-cause mortality. Thus, targeting inflammasome components may ameliorate chronic inflammation and various other age-associated conditions. Low-grade chronic inflammation has been associated with many a 5-year period in individuals who were hypertensive and who also of the diseases associated with aging1–7, but the mechanisms that exhibited other comorbidities. -

Nucleotide-binding oligomerization domain (NOD)-like receptors (NLRs) play crucial roles in the immune responses generated during the parasitic infection and also drive the inammatory response against invading parasites. However, little is known about the regulation of NLRs and inammasome activation in T. gondii-infected human small intestinal epithelial (FHs 74 Int) cells. Methods: FHs 74 Int cells infected with T. gondii were subsequently evaluated for morphological changes, cytotoxicity, expression proles of NLRs, inammasome components, caspase-cleaved interleukins (ILs), and the mechanisms of NLRP3 and NLRP6 inammasome activation. -
