[PMID: 39100429 PMCID: PMC11296507 DOI: 10.2147/ppa.s468957] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2024] [Accepted: 07/20/2024] [Indexed: 08/06/2024] Open
Abstract
Purpose This study aimed to investigate the knowledge, attitudes, and practices (KAP) of patients with allergic rhinitis towards allergen-specific immunotherapy (AIT). Methods This cross-sectional study was conducted through a questionnaire survey at The Fourth Affiliated Hospital of Zhejiang University School of Medicine from October 15, 2023, to December 3, 2023. Results A total of 550 valid questionnaires were included in the analysis. The median scores with interquartile ranges (IQR) for knowledge, attitude, and practice were 17 (11, 23), (possible range: 0-34); 20 (17, 22), (possible range: 7-35); and 30 (24, 34), (possible range: 8-40). Multivariate logistic regression analysis showed that individuals engaging in physical activity 1-3 times per week (OR = 2.895, 95% CI: [1.745, 4.804], P < 0.001), those participating in physical activity 5-7 times per week (OR = 3.811, 95% CI: [1.502, 9.671], P = 0.005), and those with higher knowledge scores (OR = 4.485, 95% CI: [2.942, 6.837], P < 0.001) were independently associated with positive practices. The structural equation modeling (SEM) results revealed that knowledge had a significant influence on attitude (β = -0.354, P = 0.010) and practice (β = 0.618, P = 0.010), and attitude also demonstrated a noteworthy impact on practice (β = -0.120, P = 0.020). Furthermore, it is worth noting that the indirect effects of knowledge on practice were statistically significant (β = 0.042, P = 0.020). Conclusion Patients with allergic rhinitis had inadequate knowledge, negative attitudes and proactive practices towards AIT. To improve their understanding and adherence, healthcare providers should prioritize education and interventions aimed at enhancing patient engagement with this treatment option.

[PMID: 38455868 PMCID: PMC10919974 DOI: 10.1155/2024/5531970] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2023] [Revised: 01/19/2024] [Accepted: 02/15/2024] [Indexed: 03/09/2024] Open
Abstract
Background Allergic rhinitis (AR) is a common chronic respiratory disease that has become a global health problem. miRNAs play an important role in multiple immune and inflammatory diseases, including AR. In this work, the mechanism by which miR-224-5p regulates AR in vivo and in vitro was examined. Methods Human nasal epithelial cells (HNEpCs) were used to establish an AR cell model induced by Der P1, and C57BL/6 mice were used to establish an AR animal model induced by OVA (ovalbumin). RT-qPCR was used to determine the level of miR-224-5p; western blot analysis was used to determine GATA3; ELISA was used to determine the levels of OVA-specific IgE, IFN-γ, IL-4, IL-5, and IL-13; flow cytometry was used to determine the differentiation of Th1 and Th2 cells; and HE and PAS staining was used to observe the histopathological alterations in the mouse nasal mucosa and spleen. Results miR-224-5p was downregulated in nasal mucosa from mice with AR and an AR cell model. Overexpressed miR-224-5p can improve AR development and attenuate AR symptoms by regulating GATA3-mediated Th1/Th2 responses. Conclusion miR-224-5p attenuates allergic reactions in mice with AR by regulating the Th1/Th2 response.

Abstract
T helper (Th) cells are central members of adaptive immunity and comprise the last line of defense against pathogen infection and malignant cell invasion by secreting specific cytokines. These cytokines then attract or induce the activation and differentiation of other immune cells, including antibody-producing B cells and cytotoxic CD8+ T cells. Therefore, the bidirectional communication between Th cells and tumor cells and their positioning within the tumor microenvironment (TME), especially the tumor immune microenvironment (TIME), sculpt the tumor immune landscape, which affects disease initiation and progression. The type, number, and condition of Th cells in the TME and TIME strongly affect tumor immunity, which is precisely regulated by key effectors, such as granzymes, perforins, cytokines, and chemokines. Moreover, microRNAs (miRNAs) have emerged as important regulators of Th cells. In this review, we discuss the role of miRNAs in regulating Th cell mediated adaptive immunity, focusing on the development, activation, fate decisions, and tumor immunity.

Abstract
Allergic rhinitis is a non-infectious chronic inflammatory disease of the nasal mucosa that affects T cells and their cytokines. T cells play significant roles in the development of allergic inflammatory diseases by orchestrating mechanisms underlying innate and adaptive immunity. Although many studies on allergic rhinitis have focused on helper T cells, molecular makeup, and pathogenesis-related transduction pathways, pathological mechanisms have not yet been completely explored. Recent studies have suggested that T cell status may play an important role in the interaction between T cells and the nasal mucosal barrier in allergic rhinitis. This study aimed to explore the interactions between T cells and nasal mucosal barriers in allergic rhinitis and to review the therapeutic modalities of pertinent biological agents involving T cells.

Abstract
Although recent studies have shown that the Notch signalling pathway induces the production of Th2-related immune factors, the exact mechanism through which Notch signalling exacerbates allergic rhinitis (AR) remains unknown. To investigate the roles of Notch in AR, serum, nasal mucosa and spleen samples were isolated from BALB/c mice. Paraffin sections were stained with haematoxylin and eosin (H&E) or periodic acid-Schiff (PAS) to assess inflammation. Flow cytometry was performed to detect group 2 innate lymphoid cells (ILC2s) in the serum samples, and cytokine levels were measured by enzyme-linked immunosorbent assays (ELISAs). The mRNA expression levels of the Notch signalling pathway components and miR-155 were measured by quantitative real-time PCR (qRT-PCR). In addition, human nasal epithelial cells (HNEpCs) were cultured to investigate the functional consequences of Notch pathway inhibition. The findings demonstrated that symptomatology and pathology were substantially altered, and AR model mice were established. In vivo stimulation with ovalbumin (OVA) significantly increased the Th2-type immune responses and the expression of OVA-sIgE, IL-4, GATA3, NF-κB and miR-155. However, the Notch signalling pathway was significantly deteriorated in AR, and this effect was accompanied by reduced Notch1, Notch2, RBPj and Hes1 levels. These effects were abrogated by gamma-secretase inhibitor IX (DAPT) treatment, and DAPT inhibited the wound healing and proliferation of HNEpCs in a dose-dependent manner. Therefore, our results suggest that blocking the Notch pathway may alleviate miR-155-mediated inflammation via the regulation of immune homeostasis in AR.

Abstract
Allergic rhinitis and asthma are common airway allergic diseases, the incidence of which has increased annually in recent years. The human body is frequently exposed to allergens and environmental irritants that trigger immune and inflammatory responses, resulting in altered gene expression. Mounting evidence suggested that epigenetic alterations were strongly associated with the progression and severity of allergic diseases. Noncoding RNAs (ncRNAs) are a class of transcribed RNA molecules that cannot be translated into polypeptides and consist of three major categories, microRNAs (miRNAs), long noncoding RNAs (lncRNAs), and circular RNAs (circRNAs). Previous studies showed that ncRNAs were involved in the physiopathological mechanisms of airway allergic diseases and contributed to their occurrence and development. This article reviews the current state of understanding of the role of noncoding RNAs in airway allergic diseases, highlights the limitations of recent studies, and outlines the prospects for further research to facilitate the clinical translation of noncoding RNAs as therapeutic targets and biomarkers.

Abstract
OBJECTIVE To find out the pathways and key genes and to reveal disc degeneration pathogenesis based on bioinformatic analyses. DESIGN The GSE70362 dataset was downloaded from the GEO (Gene Expression Omnibus) database. Differentially expressed genes (DEGs) between the patients having disc degeneration and healthy controls were screened by Limma package in R language. Critical genes were identified by adopting gene ontologies (GOs), Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways, and protein-protein interaction (PPI) networks. RESULTS We identified 112 DEGs, including 60 genes which were upregulated and 52 that were downregulated. Analyses, such as GO and KEGG demonstrated that the DEGs got enriched in 4 biological processes and 2 signaling pathways, mainly related to disc degeneration. The PPI network analyses identified 5 key proteins, CCND1 (cyclin D1), GATA3, TNFSF11, LEF1, and DKK1 (Dickkopf related protein 1). CONCLUSION In this study, the DEGs and pathways determined promoted us understand the disc degeneration mechanisms. Also, the study may contribute novel biomarkers for the diagnosis and prevention of disc degeneration, and seek new treatment methods to repair and even regenerate degenerative intervertebral disc.

MicroRNA-155-5p regulates the Th1/Th2 cytokines expression and the apoptosis of group 2 innate lymphoid cells via targeting TP53INP1 in allergic rhinitis. Int Immunopharmacol 2021; 101:108317.

Abstract
As a key component of innate immunity, group 2 innate lymphoid cells (ILC2s) play a key role in Allergic rhinitis (AR). We previously demonstrated that both miR-155-5p and ILC2s are overexpressed in the nasal mucosa of AR patients, but the underlying mechanism remains unclear. At present study, we revealed that miR-155-5p was highly expressed in ILC2s of AR patients. Moreover, miR-155-5p promoted the secretion of Th2 cytokines of ILC2s, while inhibited the secretion of Th1 cytokines and the apoptosis of ILC2s. Meanwhile, the TP53INP1 expression was poorly expressed in ILC2s of AR patients. A dual luciferase reporter assay demonstrated that TP53INP1 was a direct target of miR-155-5p, and its expression was inversely associated with miR-155-5p in ILC2s. Furthermore, TP53INP1 inhibited the secretion of Th2 cytokines of ILC2s, while promoted the secretion of Th1 cytokines and the apoptosis of ILC2s. Notably, rescue experiments demonstrated that overexpression of TP53INP1 could partially reverse the effect of miR-155-5p on ILC2s. Taken together, these findings suggested that miR-155-5p aggravated the inflammatory response of AR dominated by ILC2s via targeting TP53INP1, which may aid in the development of novel therapeutic agents for AR.

Abstract
Allergic rhinitis (AR) is an IgE-mediated upper airway disease with a high worldwide prevalence. MicroRNA (miR)-205-5p upregulation has been observed in AR; however, its role is poorly understood. The aim of the present study was to investigate the effect of miR-205-5p on AR-associated inflammation. To establish an AR model, BALB/c mice were sensitized using an intraperitoneal injection of ovalbumin (OVA) on days 0, 7 and 14, followed by intranasal challenge with OVA on days 21–27. A lentiviral sponge for miR-205-5p was used to downregulate miR-205-5p in vivo via intranasal administration on days 20–26. Reverse transcription-quantitative PCR revealed that miR-205-5p was upregulated in AR mice. Notably, miR-205-5p knockdown reduced the frequency of nose-rubbing and sneezing, and attenuated pathological alterations in the nasal mucosa. The levels of total and OVA-specific IgE, cytokines IL-4, IL-5 and IL-13, and inflammatory cells, were decreased by miR-205-5p knockdown in AR mice. In addition, miR-205-5p knockdown inhibited nucleotide-binding oligomerization domain-like receptor family pyrin domain-containing 3 (NLRP3) inflammasome activation by reducing the expression levels of NLRP3, apoptosisassociated specklike protein containing a CARD, cleaved caspase-1 and IL-1β by western blot analysis. B-cell lymphoma 6 (BCL6) was confirmed as a target of miR-205-5p by luciferase reporter assay. In conclusion, the present findings suggested that miR-205-5p knockdown may attenuate the inflammatory response in AR by targeting BCL6, which may be a potential therapeutic target for AR.

Abstract
AIMS Growth and differentiation factor 15 (GDF15) is a stress-related factor, which implicated in various diseases. This study aimed to investigate the role of GDF15 in LPS-mediated inflammation and to explore the potential underlying molecular mechanisms in human nasal epithelial cells (HNEpCs). MAIN METHODS HNEpCs were treated with LPS. GDF15 loss-of-function and gain-of-function experiments were performed. The expression of GDF15 by quantitative real-time PCR (RT-qPCR). The mRNA levels and secretion of inflammatory cytokines and MUC5AC were assessed by RT-qPCR and ELISA kits. LY294002 (PI3K inhibitor) and 740Y-P (PI3K agonist) were utilized to interfere with PI3k/Akt pathway. The relationship between GDF15 and ATF4 was identified by chromatin immunoprecipitation (ChIP) and luciferase reporter assay. KEY FINDINGS We observed that LPS triggered GDF15 expression. GDF15 ablation reduced the mRNA levels and secretion of inflammatory cytokines. GDF15 silencing led to the reduction of the MUC5AC mRNA level, protein level and secretion in response to LPS. Enhanced expression of GDF15 showed the opposite results. Furthermore, we found that GDF15 deficiency inhibited activation of the PI3K/Akt pathway, LY294002 treatment further enhanced the role of GDF15 suppression in inflammation and MUC5AC expression, while 740Y-P administration partly reversed the biological activities of GDF15 silencing. ATF4 could bind to the promoter of GDF15 and positively regulate GDF15 expression. Depression of ATF4 diminished the secretion of inflammatory cytokines and MUC5AC via regulation of GDF15. SIGNIFICANCE Our data suggest that GDF15 is regulated by ATF4 and suppresses LPS-induced inflammation and MUC5AC in human nasal epithelial cells through the PI3K/Akt pathway.

Abstract
BACKGROUND The precise mechanisms underlying pathogenesis of different subtypes of chronic rhinosinusitis with nasal polyps (CRSwNP) are still unclear. Emerging evidence indicates that microRNAs may play a role in the pathogenesis of CRSwNP. This study aimed to identify the dysregulated microRNA-messenger RNA (miRNA-mRNA) regulatory networks in eosinophilic (E) and non-eosinophilic (non-E) CRSwNP. METHODS Whole-transcriptome sequencing was performed on nasal tissues of patients with ECRSwNP and non-ECRSwNP, and control subjects. An integrated analysis of miRNA and mRNA expression was conducted to identify key mRNAs and miRNAs involved in the pathogenesis of ECRSwNP and non-ECRSwNP. The miRNAs of interest and their target genes were validated using quantitative real-time polymerase chain reaction (PCR). RESULTS A group of differentially expressed mRNAs (DE-mRNAs) and miRNAs (DE-miRs) were identified in ECRSwNP patients vs control subjects, non-ECRSwNP patients vs control subjects, and non-ECRSwNP vs ECRSwNP patients, respectively. Pathway enrichment analysis showed distinct immune and inflammatory functions associated with DE-mRNAs and target genes of DE-miRs in ECRSwNP vs control and non-ECRSwNP vs control groups. The miRNA-mRNA regulatory networks constructed with Cytoscape highlighted the roles of miR-154, miR-221, and miR-223 family miRNAs relating to both ECRSwNP and non-ECRSwNP, and the roles of the let-7 and miR-34/449 families in the development of non-ECRSwNP. Assessment using real-time PCR for the expression of miRNAs and target genes demonstrated highly consistent data with the RNA sequencing data. CONCLUSION ECRSwNP and non-ECRSwNP patients express distinct miRNA-mRNA regulatory networks compared with control subjects, thus providing potential targets for future development of novel therapeutic approaches for the management of CRSwNP.
