Abstract
BACKGROUND Chronic prostatitis (CP), a frequent male urological disease, is featured with chronic pelvic pain and various discomfort. Calycosin has anti-inflammatory effect and its exact mechanism in CP remains unknown. OBJECTIVE Our research was designed to explain the underlying mechanism of calycosin in CP and illustrate our findings in the rats and LPS-ATP-induced RWPE-1 cells. METHODS The pathology of prostate tissues was analyzed by HE staining and histological inflammation score. The concentration of inflammatory factors were detected via ELISA assay. Besides, the representative biomarkers of oxidative stress were measured through detection kits. The ROS production, NLRP3 and GSDMD expression were evaluated by immunofluorescence or immumohistochemical staining. Furthermore, the expression of NF-kBp65 pathway-associated proteins and pyroptosis-associated proteins were detected by western blotting. RWPE-1 cells growth and pyroptosis were assessed by CCK-8 and flow cytometry, respectively. mRNA levels of pyroptosis markers were detected by qRT-PCR analysis. RESULTS The CP model in vivo and in vitro was successfully established by carrageenan and LPS-ATP, respectively. Calycosin substantially ameliorated the pathological damage of prostate tissue. Moreover, calycosin treatment promoted RWPE-1 cells viability and reduced pyroptosis. Calycosin remarkably reduced the inflammatory factors secretion and oxidative stress markers. Calycosin stimulation effectively suppressed the pyroptosis, which was linked with inactivation of the NF-kBp65 signaling pathway. These beneficial effects of calycosin were similar to the NLRP3 inhibitor (MCC950). CONCLUSION To sum up, our observations indicated that calycosin protects against CP via suppressing inflammation, oxidative stress, and pyroptosis through NF-kBp65 pathway, thereby serving as a promising therapy for CP treatment.

Abstract
Ferroptosis is a newly discovered type of regulated cell death participated in multiple diseases. Different from other classical cell death programs such as necrosis and apoptosis, ferroptosis involving iron-catalyzed lipid peroxidation is characterized by Fe2+ accumulation and mitochondria alterations. The phenomenon of oxidative stress following organ ischemia-reperfusion (I/R) has recently garnered attention for its connection to the onset of ferroptosis and subsequent reperfusion injuries. This article provides a comprehensive overview underlying the mechanisms of ferroptosis, with a further focus on the latest research progress regarding interference with ferroptotic pathways in organ I/R injuries, such as intestine, lung, heart, kidney, liver, and brain. Understanding the links between ferroptosis and I/R injury may inform potential therapeutic strategies and targeted agents.

Int Immunopharmacol 2024; 143:113416. [PMID: 39426227 DOI: 10.1016/j.intimp.2024.113416] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2024] [Revised: 09/15/2024] [Accepted: 10/13/2024] [Indexed: 10/21/2024]
Abstract
BACKGROUND Ferroptosis, an iron-dependent form of cell death, plays a pivotal role in the pathologic progression of asthma. Electroacupuncture (EA) has demonstrated considerable efficacy in mitigating asthma airway inflammation, although its underlying mechanisms remain partially elucidated. METHODS We investigated the regulatory effect of NLRP3 on ferroptosis using a lipopolysaccharide (LPS)-induced inflammation model in BEAS-2B cells, where NLRP3 expression was modulated with si-RNA and overexpression plasmids. The levels of inflammatory cytokines TNF-α, IL-1β, and IL-6 were quantified. We also assessed NLRP3 and JAK2/STAT3 pathway-related proteins, and evaluated lipid peroxidation, mitochondrial membrane potential (ΔΨm), and antioxidant system functionality. In vivo, we examined the impact of EA on ferroptosis and airway inflammation by modulating NLRP3 activation. Asthma inflammation severity was evaluated using H&E, Masson, and PAS staining, alongside ELISA. NLRP3 and JAK2/STAT3 pathway-related proteins, as well as ferroptosis indicators, were also analyzed. The mechanism by which NLRP3 activates ferroptosis was investigated through in vitro assays. RESULTS LPS exposure resulted in increased intracellular inflammatory cytokines, and activation of the NLRP3 and JAK2/STAT3 pathways, leading to enhanced lipid peroxidation, decreased ΔΨm, and disruption of antioxidant system balance, ultimately inducing ferroptosis. Si-NLRP3 countered the effects of LPS, whereas oe-NLRP3 exacerbated symptoms. In vivo studies revealed that EA reduced airway inflammation, inhibited NLRP3 activation, and decreased phosphorylation of JAK2/STAT3, effectively lowering ferroptosis-related indicators. Utilizing JAK2/STAT3 activators and inhibitors, we confirmed that NLRP3 mediates ferroptosis via the JAK2/STAT3 pathway. CONCLUSIONS EA alleviates HDM-induced asthma, primarily through the inhibition of NLRP3 activation, which modulates the JAK2/STAT3 pathway and mediates ferroptosis.

Abstract
Stroke is a severe neurological disease and a major worldwide issue, mostly manifesting as ischemic stroke (IS). In order to create effective treatments for IS, it is imperative to fully understand the underlying pathologies, as the existing therapeutic choices are inadequate. Recent investigations have shown the complex relationships between several programmed cell death (PCD) pathways, including necroptosis, ferroptosis, and pyroptosis, and their correlation with immune responses during IS. However, this relationship is still unclear. To address this gap, this review study explored the cellular interactions in the immune microenvironment of IS. Then, to validate prior findings and uncover biomarkers, the study investigated bioinformatics studies. Several pathways, including nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB), Toll-like receptor 4 (TLR4), and receptor-interacting protein kinase (RIPK), were involved in PCD-immune interactions. The bioinformatics studies reported key biomarkers such as glutathione peroxidase 4 (GPX4), NOD-like receptor family pyrin domain containing 3 (NLRP3), gasdermin D (GSDMD), and TLR4, which have important implications in ferroptosis, cuproptosis, pyroptosis, and necroptosis respectively. These biomarkers were associated with PCD mechanisms such as oxidative stress and inflammatory reactions. The immune infiltration analysis consistently revealed a significant correlation between PCD pathways and detrimental immune cells, such as neutrophils and γδ T cells. Conversely, M2 macrophages and T helper cells showed protective effects. In conclusion, considering the intricate network of interactions between immune responses and PCD pathways, this study emphasized the necessity of a paradigm shift in therapeutic approaches to address the injuries that are related to this complex network.

[PMID: 39443194 DOI: 10.1016/j.cytogfr.2024.10.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2024] [Revised: 10/06/2024] [Accepted: 10/06/2024] [Indexed: 10/25/2024]
Abstract
Neuroinflammation is a critical component in neurodegenerative disorders. The inflammasome, facilitates the cleavage of caspase-1, leading to the maturation and subsequent secretion of inflammatory factors interleukin (IL)-1β and IL-18. Consequently, pyroptosis mediated by gasdermin D, exacerbates neuroinflammation. Among the inflammasomes, NLRP1/3 are predominant in the central nervous system (CNS), Although NLRP1 was the earliest discovered inflammasome, the specific involvement of NLRP1 in neurodegenerative diseases remains to be fully elucidated. Recently, the discovery of an endogenous inhibitor of NLRP1, dipeptidyl peptidase 9, suggests the feasibility of producing of small-molecule drugs targeting NLRP1. This review describes the latest findings on the role of the NLRP1 inflammasome in the pathology of neurodegenerative disorders, including Alzheimer's disease, and summarises the regulatory mechanisms of NLRP1 inflammasome activation in the CNS. Furthermore, we highlight the recent progress in developing small-molecule and biological inhibitors that modulate the NLRP1 infammasome for the treatment of neurodegenerative disorders, some of which are advancing to preclinical testing. SIGNIFICANCE STATEMENT: The objective of this review is to synthesise the research on the structure, activation, and regulatory mechanisms of the NLRP1 inflammasome, along with its potential impact on both acute and chronic neurodegenerative conditions. The discovery of endogenous inhibitors, such as dipeptidyl peptidase 9 and thioredoxin, and their interaction with NLRP1 suggest the possibility of developing NLRP1-targeted small-molecule drugs for the treatment of neurodegenerative disorders. This review also discusses the use of both direct and indirect NLRP1 inhibitors as prospective therapeutic strategies for these conditions.

Abstract
OBJECTIVES Fulminant hepatic failure is a critical condition with a high mortality rate. Currently, liver transplantation is considered one of the most effective treatment methods, but the shortage of organ resources has presented a major obstacle. The use of marginal donor livers, including those from syphilis-positive donors, offers new opportunities. This study reviewed and analyzed data from our center to summarize the management experience of using syphilis-positive donor livers to treat fulminant hepatic failure. MATERIALS AND METHODS From January 2016 to December 2021, 17 adult patients with fulminant hepatic failure received liver transplants from syphilis-positive donors at our center. Given the imbalance in several baseline variables, propensity score matching was used. We compared outcomes, including complications, hospital stay, recovery of liver function, and survival rates between groups of patients with syphilis-positive and syphilis-negative grafts. We also reviewed treatment of recipients of syphilis-positive livers. RESULTS No significant differences were shown in complications and hospital stays between recipients of syphilis-positive and syphilis-negative grafts. Both groups showed similar trends in liver function recovery. Patient and graft survival rates were comparable between the groups. Benzathine penicillin effectively protected recipients from syphilis. CONCLUSIONS Use of liver grafts from syphilis-positive donors did not increase morbidity and mortality in recipients. Liver transplant can effectively treat patients with fulminant hepatic failure. In addition, prophylactic use of benzathine penicillin was beneficial.

Abstract
The role of interleukin-18 (IL-18) and inflammasomes in chronic inflammatory airway diseases, such as asthma and chronic obstructive pulmonary disease (COPD), has garnered significant attention in recent years. This review aims to provide an overview of the current understanding of IL-18 biology, the associated signaling pathways, and the involvement of inflammasome complexes in airway diseases. We explore the multifaceted role of IL-18 in asthma pathophysiology, including its interactions with other cytokines and contributions to both T2 and non-T2 inflammation. Importantly, emerging evidence highlights IL-18 as a critical player in severe asthma, contributing to chronic airway inflammation, airway hyperresponsiveness (AHR), and mucus impaction. Furthermore, we discuss the emerging evidence of IL-18's involvement in autoimmunity and highlight potential therapeutic targets within the IL-18 and inflammasome pathways in severe asthma patients with evidence of infections and airway autoimmune responses. By synthesizing recent advancements and ongoing research, this review underscores the importance of IL-18 as a potential novel therapeutic target in the treatment of severe asthma and other related conditions.

Abstract
Diabetic cardiomyopathy (DCM) is a common complication of diabetes, and its pathogenesis remains elusive. Ferroptosis, a process dependent on iron-mediated cell death, plays a crucial role in DCM via disrupted iron metabolism, lipid peroxidation, and weakened antioxidant defenses. Hyperglycemia, oxidative stress, and inflammation may exacerbate ferroptosis in diabetes. This review emphasizes the interaction between cardiac fibroblasts and cardiomyocytes in DCM, influencing ferroptosis occurrence. By exploring ferroptosis modulation for potential therapeutic targets, this article offers a fresh perspective on DCM treatment. The study systematically covers the interplay, mechanisms, and targeted drugs linked to ferroptosis in DCM development.

Inflammasomes are important modulators of inflammation. Dysregulation of inflammasomes can enhance vulnerability to conditions such as neurodegenerative diseases, autoinflammatory diseases, and metabolic disorders. Among various inflammasomes, Nucleotide-binding oligomerization domain leucine-rich repeat and pyrin domain-containing protein 3 (NLRP3) is the best-characterized inflammasome related to inflammatory and neurodegenerative diseases. NLRP3 is an intracellular sensor that recognizes pathogen-associated molecular patterns and damage-associated patterns resulting in the assembly and activation of NLRP3 inflammasome. The NLRP3 inflammasome includes sensor NLRP3, adaptor apoptosis-associated speck-like protein (ASC), and effector cysteine protease procaspase-1 that plays an imperative role in caspase-1 stimulation which further initiates a secondary inflammatory response. Regulation of NLRP3 inflammasome ameliorates NLRP3-mediated diseases. Much effort has been invested in studying the activation, and exploration of specific inhibitors and epigenetic mechanisms controlling NLRP3 inflammasome. This review gives an overview of the established NLRP3 inflammasome assembly, its brief molecular mechanistic activations as well as a current update on specific and non-specific NLRP3 inhibitors that could be used in NLRP3-mediated diseases. We also focused on the recently discovered epigenetic mechanisms mediated by DNA methylation, histone alterations, and microRNAs in regulating the activation and expression of NLRP3 inflammasome, which has resulted in a novel method of gaining insight into the mechanisms that modulate NLRP3 inflammasome activity and introducing potential therapeutic strategies for CNS disorders.

Abstract
BACKGROUND Growth and differentiation factor 15 (GDF15) has been proved to regulate the process of Myocardial ischemia-reperfusion injury (MIRI), which is a serious complication of reperfusion therapy. The present study aimed to explore if GDF15 could regulate the MIRI-induced ferroptosis. METHOD MIRI animal model was established by ligating the left anterior descending coronary artery. Oxygen-glucose deprivation/reoxygenation (OGD/R) cell model was established to imitate MIRI in vitro. The indicators of ferroptosis including mitochondrial damage, GPX4, FACL4, XCT4, and oxidative stress markers were evaluated. RESULTS Overexpression of GDF15 greatly inhibited MIRI, improved cardiac function, alleviated MIRI-induced ferroptosis. pc-DNA-GDF15 significantly inhibited the oxidative stress condition and inflammation response. The OGD/R-induced ferroptosis was also inhibited by pc-DNA-GDF15. CONCLUSION We proved that the MIRI-induced ferroptosis could by inhibited by pc-DNA-GDF15 through evaluating mitochondrial damage, MDA, GSH, and GSSG. Our research provides a new insight for the prevention and treatment of MIRI, and a new understanding for the mechanism of MIRI-induced ferroptosis.
