[PMID: 38277371 PMCID: PMC10817214 DOI: 10.1371/journal.pone.0296994] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2023] [Accepted: 12/21/2023] [Indexed: 01/28/2024] Open
Abstract
BACKGROUND Immune-mediated conjunctivitis is a prevalent ocular ailment characterized by inflammation and immune reactions in the conjunctiva. However, the precise causes and therapeutic approaches for this condition remain the main focus for numerous ophthalmological specialists. Recently, accumulating evidence from human and mouse experiments has demonstrated the critical involvement of the NLRP3 inflammasome, IL-1β, and IL-18 in the development of allergic diseases. Targeting specific NLRP3 inflammasome and its related inhibitors may hold potential as therapeutic agents for immunologic conjunctivitis. Despite this, there has been no systematic review specifically addressing the treatment of immunologic conjunctivitis related to NLRP3. Therefore, this study aims to conduct a systematic review and meta-analysis of currently published randomized controlled trials (RCTs) on NLRP3-related treatments for immunologic conjunctivitis patients, with the goal of evaluating their efficacy and safety. METHODS We will conduct a comprehensive search for relevant studies on NLRP3 inflammasome inhibitors or NLRP3-related treatments for immunologic conjunctivitis in various databases including PubMed, EMBASE, Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP, and Wanfang. The search will encompass studies from their respective inception dates to July 2023. A meta-analysis will be performed using data extracted from eligible randomized controlled trials (RCTs), focusing on the clinical manifestations of immunologic conjunctivitis, levels of NLRP3-related factors in serum or tear samples, quality of life outcomes, and adverse events. Review Manager 5.4.1 software will be employed for the meta-analysis, and the results will be analyzed using either random-effects or fixed-effects models, depending on the presence of heterogeneity. The reliability and quality of evidence will be evaluated using the Grading of Recommendations, Development, and Evaluation (GRADE) system. RESULTS The findings of this study will yield robust and high-quality evidence regarding the efficacy and safety of NLRP3-related treatments for immunologic conjunctivitis. This evidence will contribute significantly to our understanding of the potential benefits and risks associated with such treatments and will assist healthcare professionals in making informed decisions regarding the management of immunologic conjunctivitis. CONCLUSION This study represents the first comprehensive meta-analysis aiming to evaluate the efficacy and safety of NLRP3-related treatments for immunologic conjunctivitis. The findings from this study will provide valuable evidence to guide clinical management strategies for this disease. The results are anticipated to significantly contribute to the understanding of the therapeutic potential and safety profile of NLRP3-related treatments, offering valuable insights for healthcare professionals involved in the care of patients with immunologic conjunctivitis. TRIAL REGISTRATION Systematic review registration: PROSPERO with registration number CRD42023437076.

Abstract
Vernal keratoconjunctivitis (VKC) is a chronic, bilateral corneal and conjunctival problem which typically presents in young individuals. VKC is characterized by itching, photophobia, white mucous discharge, lacrimation, foreign body sensation, and pain due to corneal involvement of shield ulcers. Vernal keratoconjunctivitis is categorized within ocular diseases. The diagnosis is clinical, as no sure biomarkers pathognomonic of the disease have yet been identified. The VKC therapy relies on different types of drugs, from antihistamines and topical steroids to cyclosporine or tacrolimus eye drops. In extremely rare cases, there is also the need for surgical treatment for the debridement of ulcers, as well as for advanced glaucoma and cataracts, caused by excessive prolonged use of steroid eye drops. We performed a systematic review of the literature, according to PRISMA guideline recommendations. We searched the PubMed database from January 2016 to June 2023. Search terms were Vernal, Vernal keratoconjunctivitis, and VKC. We initially identified 211 articles. After the screening process, 168 studies were eligible according to our criteria and were included in the review. In this study, we performed a systematic literature review to provide a comprehensive overview of currently available diagnostic methods, management of VKC, and its treatments.

Abstract
Vernal keratoconjunctivitis (VKC) is a chronic, recurrent, inflammatory disease of the cornea and conjunctiva mostly affecting boys in prepubertal age. VKC recurrence is characterized by intense symptoms of itching, redness, and photophobia associated with corneal damage, impairment of visual function, and quality of life. The pathogenesis of VKC has not yet been completely understood, and it is still controversial. In fact, VKC is considered an ocular allergic disease due to the involvement of immunoglobulin E, eosinophils, and mast cells, and of a lymphocyte T-helper type 2 reaction. However, approximately half of VKC patients have negative allergological history and testing, suggesting that other pathogenic mechanisms participate in VKC development and severity. Specifically, evidence suggests that genetic, endocrine, neuronal factors and an imbalance of innate immunity are involved in the pathogenesis of VKC. The purpose of this review is to summarize evidence on the pathogenic role of innate immunity, neuroimmune reaction, and hormonal changes in VKC. Increasing understanding of the pathogenic mechanisms behind VKC may lead to the identification of novel biomarkers for diagnosis and/or potential therapeutic targets in order to improve the management of this challenging condition.

HSP60 Regulates Monosodium Urate Crystal-Induced Inflammation by Activating the TLR4-NF- κB-MyD88 Signaling Pathway and Disrupting Mitochondrial Function. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2020; 2020:8706898. [PMID: 33488933 PMCID: PMC7791970 DOI: 10.1155/2020/8706898] [Citation(s) in RCA: 31] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/31/2020] [Revised: 12/01/2020] [Accepted: 12/06/2020] [Indexed: 02/06/2023]
Abstract
Acute gout is an inflammatory response induced by monosodium urate (MSU) crystals. HSP60 is a highly conserved stress protein that acts as a cellular "danger" signal for immune reactions. In this study, we aimed to investigate the role and molecular mechanism of HSP60 in gout. HSP60 expression was detected in peripheral blood mononuclear cells (PBMCs) and plasma of gout patients. The effect and molecular mechanism of HSP60 in gout were studied in MSU crystals treatment macrophages and C57BL/6 mice. JC-1 probe and MitoSOX Red were used to measure the mitochondrial membrane potential (MMP) and mitochondrial reactive oxygen species (mtROS). HSP60 expression was significantly upregulated in the PBMCs and sera of patients with acute gout (AG) compared to those with intercritical gout (IG) or healthy controls (HCs). MSU crystals induced the expression and secretion of HSP60 in the macrophages. HSP60 knockdown or overexpression affects TLR4 and MyD88 expression, IκBα degradation, and the nuclear localization of NF-κB in MSU crystal-stimulated inflammation. Further, HSP60 facilitates MMP collapse and mtROS production and activates the NLRP3 inflammasome in MSU crystal-stimulated macrophages. In MSU crystal-induced arthritis mouse models pretreated with HSP60 vivo-morpholino, paw swelling, myeloperoxidase (MPO) activity, and inflammatory cell infiltration significantly decreased. Our study reveals that MSU crystal stimulates the expression of HSP60, which accelerates the TLR4-MyD88-NF-κB signaling pathway and exacerbates mitochondrial dysfunction.

Abstract
We aimed to evaluate the effects of dihydroartemisinin (DHA) on heat-shock protein 70 (HSP70) expression in human prostate cancer PC-3 cells and to examine the molecular mechanism. The viability of PC-3 cells following treatment with 25, 50, 100 and 200 μmol/L DHA for 48 hr was detected by flow cytometry and MTT assay. The expression of HSP70 mRNA was detected by RT-qPCR. The expression levels and locations of HSP70, caspase-3 and apoptosis-inducing factor (AIF) were detected with immunofluorescence assay. With 100 μmol/L HSP70 inhibitor quercetin as positive control and dimethyl sulphoxide (DMSO) as solvent control, the protein expressions of HSP70, apoptotic protease activating factor-1 (Apaf-1) and AIF were detected by Western blot. DHA promoted PC-3 cell apoptosis dose-dependently. With increasing DHA dose, the expression of HSP70 mRNA significantly decreased (p < 0.05). DHA did not change the location of HSP70 or AIF. Compared with control and DMSO groups, the expression of HSP70 protein significantly decreased, and those of Apaf-1, caspase-3 and AIF significantly increased following treatment with DHA and quercetin for 48 hr. In conclusion, DHA inhibits the expression of HSP70 and induces the apoptosis of PC-3 cells. The results provide valuable experimental evidence for prostate cancer therapies using DHA.

Abstract
Inflammatory bowel disease (IBD) encompasses various pathological conditions similar but distinct that share a multifactorial etiology, including involvement of the intestinal barrier function, the immune system, and intestinal microorganisms. Hsp60 is a chaperonin component of the chaperoning system, present in all cells and tissues, including the intestine. It plays important roles in cell physiology outside and inside mitochondria, its canonical place of residence. However, Hsp60 can also be pathogenic in many conditions, the Hsp60 chaperonopathies, possibly including IBD. The various clinico-pathological types of IBD have a complicated mix of causative factors, among which Hsp60 can be considered a putatively important driver of events and could play an etiopathogenic role. This possibility is discussed in this review. We also indicate that Hsp60 can be a biomarker useful in disease diagnosing and monitoring and, if found active in pathogenesis, should become a target for developing new therapies. The latter are particularly needed to alleviate patient suffering and to prevent complications, including colon cancer.

Abstract
Pterygium is a common ocular surface disease induced by a variety of factors. The exact pathogenesis of pterygium remains unclear. Numbers of genes and proteins are discovered in pterygium and they function differently in the occurrence and development of this disease. We searched the Web of Science and PubMed throughout history for literatures about the subject. The keywords we used contain pterygium, gene, protein, angiogenesis, fibrosis, proliferation, inflammation, pathogenesis and therapy. In this review, we summarize the aberrant expression of a range of genes and proteins in pterygium compared with normal conjunctiva or cornea, including growth factors, matrix metalloproteinases and tissue inhibitors of metalloproteinases, interleukins, tumor suppressor genes, proliferation related proteins, apoptosis related proteins, cell adhesion molecules, extracellular matrix proteins, heat shock proteins and tight junction proteins. We illustrate their possible mechanisms in the pathogenesis of pterygium as well as the related intervention based on them for pterygium therapy.
