Unraveling the unphosphorylated STAT3-unphosphorylated NF-κB pathway in loss of function STAT3 Hyper IgE syndrome. Front Immunol 2024; 15:1332817. [PMID: 39229272 PMCID: PMC11369709 DOI: 10.3389/fimmu.2024.1332817] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2023] [Accepted: 04/09/2024] [Indexed: 09/05/2024] Open
Abstract
Background Patients with loss of function signal transducer and activator of transcription 3-related Hyper IgE Syndrome (LOF STAT3 HIES) present with recurrent staphylococcal skin and pulmonary infections along with the elevated serum IgE levels, eczematous rashes, and skeletal and facial abnormalities. Defective STAT3 signaling results in reduced Th17 cells and an impaired IL-17/IL-22 response primarily due to a compromised canonical Janus kinase-signal transducer and activator of transcription (JAK-STAT) pathway that involves STAT3 phosphorylation, dimerization, nuclear translocation, and gene transcription. The non-canonical pathway involving unphosphorylated STAT3 and its role in disease pathogenesis, however, is unexplored in HIES. Objective This study aims to elucidate the role of unphosphorylated STAT3-unphosphorylated NF-κB (uSTAT3-uNF-κB) activation pathway in LOF STAT3 HIES patients. Methodology The mRNA expression of downstream molecules of unphosphorylated STAT3-unphosphorylated NF-κB pathway was studied in five LOF STAT3 HIES patients and transfected STAT3 mutants post-IL-6 stimulation. Immunoprecipitation assays were performed to assess the binding of STAT3 and NF-κB to RANTES promoter. Results A reduced expression of the downstream signaling molecules of the uSTAT3-uNF-κB complex pathway, viz., RANTES, STAT3, IL-6, IL-8, ICAM1, IL-8, ZFP36L2, CSF1, MRAS, and SOCS3, in LOF STAT3 HIES patients as well as the different STAT3 mutant plasmids was observed. Immunoprecipitation studies showed a reduced interaction of STAT3 and NF-κB to RANTES in HIES patients. Conclusion The reduced expression of downstream signaling molecules, specially RANTES and STAT3, confirmed the impaired uSTAT3-uNF-κB pathway in STAT3 LOF HIES. Decreased levels of RANTES and STAT3 could be a significant component in the disease pathogenesis of Hyper IgE Syndrome.

Abstract
The idea of "one airway, one disease" has been gaining importance in the last decade. In the upper and lower airways, allergic mechanisms interact with each other. In the initial stage of respiratory allergic inflammation, allergens contact the respiratory epithelium, which produces chemokines and inflammatory factors, which cause allergic reactions by binding to the corresponding receptors and chemotactic various inflammatory cells to reach the epithelium and tissues. It also drives inflammatory cells to activate and produce more inflammatory factors, thus producing a cascade amplification effect. Inflammatory cell aggregation and activation are very complex and interact with each other in a lattice structure. By blocking the action of various chemokines, inflammatory cell aggregation is reduced, and ultimately the symptoms of respiratory allergy are alleviated. Chemokines can serve as cues for coordinated recruitment of immune cells into and out of tissues, as well as directing the spatial organization of immune cells within tissues and cellular interactions. Chemokines are critical in directing immune cell migration and thus have an important role in the direction of respiratory allergy: however, chemokines are also involved in the production and recruitment of immune cells that contribute to respiratory allergy. In this article, linking the upper and lower respiratory tracts. We review the role of the chemokine system in the respiratory immune response and discuss how respiratory disease modulates overall chemokines to shape the type and outcome of the immune response to the treatment of respiratory allergic disease so that we can further deepen our knowledge of chemokines in the direction of respiratory allergy. In the future, we can do drug research and development based on this network structure and explore new research directions.

Abstract
BACKGROUND It has been suggested that genetic factors may predispose individuals to periodontal diseases. The present case-control study aims to test whether the -403 single nucleotide polymorphism of chemokine ligand 5 (CCL5-403) and the 32-bp deletion of CCR5 (CCR5Δ32) polymorphisms are associated with susceptibility to chronic and aggressive periodontitis. METHODS Taiwanese participants (N = 213) were grouped into control group (CG), generalized aggressive periodontitis (GAgP), or chronic periodontitis (CP) groups. DNA samples were obtained from peripheral blood. CCL5-403, evaluated by polymerase chain reaction-restriction fragment length polymorphism, and CCR5Δ32, evaluated by polymerase chain reaction, were compared among the three groups. RESULTS There was a significant association between type of periodontitis and having allele A or G in the CCL5-403 polymorphism. GAgP patients were 3.7 times more likely than CP patients and 2.0 times more likely than CG patients to have allele A, instead of allele G, in CCL5-403. GAgP patients were 3.1 times more likely than CG patients to have AG versus GG genotype. GAgP patients were also 5.0 and 19.8 times more likely than CP patients to have AG and AA genotypes, respectively, compared to GG. For the CCR5Δ32 polymorphism, no association was found between the type of periodontitis and having different genotype or allele distributions among GAgP, CP, or CG patients. CONCLUSION The single nucleotide polymorphism of CCL5-403 G substitution by A may play a role in AgP; however, the CCR5Δ32 polymorphism may not.

Abstract
Replication of reported associations is crucial to the investigation of complex disease. More than 100 SNPs have previously been reported as associated with allergic rhinitis (AR), but few of these have been replicated successfully. To investigate the general reproducibility of reported AR-associations in candidate gene studies, one Swedish (352 AR-cases, 709 controls) and one Singapore Chinese population (948 AR-cases, 580 controls) were analyzed using 49 AR-associated SNPs. The overall pattern of P-values indicated that very few of the investigated SNPs were associated with AR. Given published odds ratios (ORs) most SNPs showed high power to detect an association, but no correlations were found between the ORs of the two study populations or with published ORs. None of the association signals were in common to the two genome-wide association studies published in AR, indicating that the associations represent false positives or have much lower effect-sizes than reported.

Abstract
There is a significant genetic contribution to allergic rhinitis (AR). Genetic association studies for AR have been performed, but varying results make it challenging to decipher the overall potential effect of specific variants. The Th2 pathway plays an important role in the immunological development of AR. We performed meta-analyses of genetic association studies of variants in Th2 pathway genes and AR. PubMed and Phenopedia were searched by double extraction for original studies on Th2 pathway-related genetic polymorphisms and their associations with AR. A meta-analysis was conducted on each genetic polymorphism with data meeting our predetermined selection criteria. Analyses were performed using both fixed and random effects models, with stratification by age group, ethnicity, and AR definition where appropriate. Heterogeneity and publication bias were assessed. Six independent studies analyzing three candidate polymorphisms and involving a total of 1596 cases and 2892 controls met our inclusion criteria. Overall, the A allele of IL13 single nucleotide polymorphism (SNP) rs20541 was associated with increased odds of AR (estimated OR=1.2; 95% CI 1.1-1.3, p-value 0.004 in fixed effects model, 95% CI 1.0-1.5, p-value 0.056 in random effects model). The A allele of rs20541 was associated with increased odds of AR in mixed age groups using both fixed effects and random effects modeling. IL13 SNP rs1800925 and IL4R SNP 1801275 did not demonstrate overall associations with AR. We conclude that there is evidence for an overall association between IL13 SNP rs20541 and increased risk of AR, especially in mixed-age populations.

Abstract
BACKGROUND Genetics of acute allergies has focused on identifying single nucleotide polymorphisms (SNPs) within genes relevant in the pathogenesis. In this study, we begin a systems biology analysis of the interconnectivity and biological functions of these genes, their transcripts and their corresponding proteins. METHODS The literature (Pubmed) was searched for SNPs within genes relevant in acute allergic diseases. The SNP-modified genes were converted to corresponding proteins and their protein-protein interactions were searched from six different databases. This interaction network was analysed with annotated vocabularies (ontologies), such as Gene Ontology, Reactome and Nature pathway interaction database. Time-series transcriptomics was performed with nasal epithelial cells obtained from allergic patients and their healthy control subjects. RESULTS A total of 39 genes with SNPs related to acute allergic diseases were found from a literature search. The corresponding proteins were then hooked into a large protein-protein interaction network with the help of various databases. Twenty-five SNP-related proteins had more than one interacting protein and a network contained 95 proteins, and 182 connections could be generated. This network was 10-fold enriched with protein kinases and proteins involved in the host-virus interaction compared with background human proteome. Finally, eight of the 95 nodes on our network displayed nasal epithelial transcriptomal regulation in a time-series analysis collected from birch allergic patients during the spring pollen season. CONCLUSIONS Signal transduction with special reference to host-virus interactions dominated in the allergy-related protein interaction network. Systems level analysis of allergy-related mutation can provide new insights into pathogenetic mechanisms of the diseases.

Abstract
OBJECT The endoscopic endonasal approach has become the preferred technique for CSF leak and encephalocele repair of the anterior skull base. The purpose of this study is to identify patient characteristics; review adjunctive perioperative treatments, reconstruction techniques, and outcomes; and identify risk factors for failure in patients undergoing endoscopic endonasal repair of anterior skull base CSF leaks and encephaloceles. METHODS This is a prospective observational study of patients undergoing endoscopic endonasal repair of a CSF leak between October 2004 and May 2009. Twenty-eight consecutive patients underwent 32 procedures. Twenty-two of the patients were women, which represents a statistically significant trend toward the female sex (p < 0.05). The average body mass index (33.9) was significant for obesity. The origin of the skull base defect included the cribriform plate (in 9 cases), fovea ethmoidalis (in 7), combined fovea ethmoidalis/cribriform plate (in 2), lateral sphenoid sinus (in 6), sella (in 4), clivus (in 3), and frontal sinus (in 1). RESULTS The overall endonasal closure rate was 93.8% (30 of 32 procedures). One failure occurred due to overaggressive postoperative debridement, while the other recurred along the posterior wall of the frontal sinus, and endoscopic repair would have occluded the recess. CONCLUSIONS The endoscopic endonasal approach for the treatment of CSF leaks and encephaloceles of the anterior skull base is the preferred method of repair in the vast majority of cases. The authors' 93.8% closure rate in a variety of anatomical locations compares favorably with the transcranial approach and echoes the results of other endoscopic series.

Abstract
Eosinophil cationic protein (ECP), a potent cytotoxic molecule, is released by activated eosinophils. ECP has been suggested to be involved in tissue remodeling of allergic diseases. The ECP (RNase3) gene is a candidate gene in atopic diseases. RNase3 polymorphisms have been reported to have an association with atopy. We determined whether polymorphisms in the RNase3 gene are associated with allergic rhinitis in a Korean population. The Taqman assay, restriction fragment length polymorphism (PCR-RFLP), and high-resolution melt (HRM) were used for genotyping. Three single nucleotide polymorphisms (SNPs; g.-550A>G, g.371G>C, and g.499G>C) were identified. The genotype of the SNPs was analyzed in patients with allergic rhinitis and controls without allergic rhinitis. The genotype and allele frequencies were compared between both groups. The genotype frequencies of the g.-550A>G and g.371G>C SNPs were not significantly different between patients with allergic rhinitis and controls (P > 0.05). However, in patients with allergic rhinitis, the genotype and allele frequencies of the g.499G>C SNP of RNase 3 were significantly different from those of the control group (P < 001, P = 0.034, respectively). Haplotype analysis demonstrated the presence of the following five different (-550)-(+371)-(+499) major haplotypes: A-G-G, G-C-C, G-G-G, G-C-G, and A-G-C. The G-C-G haplotype was positively associated with allergic rhinitis (P = 0.048), while the G-G-G haplotype was negatively associated with allergic rhinitis (P = 0.004). Our study suggests that RNase3 polymorphisms are potentially associated with susceptibility to allergic rhinitis.

Abstract
Chemoattractant peptides (chemokines) and cytokines have been shown to play a key role in the inflammatory development and progression of cerebrovascular disease. The effect of polymorphisms in regulated upon activation, normal T cells expressed, and secreted (RANTES) and interleukin-4 (IL-4) genes on cerebral infarction (CI) is evaluated in this study. Patients with CI (n = 320) and healthy controls (n = 481) were genotyped for RANTES-403 and IL-4 variable number of tandem repeat (VNTR) polymorphisms using polymerase chain reaction (PCR) or PCR-restriction fragment length polymorphism. A significant difference was observed between the CI group and controls in subjects with the RANTES AA genotype in IL-4 A3- carriers (18.6% vs. 13.1%, P = 0.035, odds ratio = 1.5, 95% confidence interval = 1.03-2.25). These findings suggest that the RANTES G-403A allele increased the relative risk for CI in the subjects without the IL-4 VNTR allele 3.

Abstract
In this second review on chemokines, we focus on the polymorphisms and alternative splicings and on their consequences in disease. Because chemokines are key mediators in the pathogenesis of inflammatory, autoimmune, vascular and neoplastic disorders, a large number of studies attempting to relate particular polymorphisms of chemokines to given diseases have already been conducted, sometimes with contradictory results. Reviewing the published data, it becomes evident that some chemokine genes that are polymorphic have alleles that are found repeatedly, associated with disease of different aetiologies but sharing some aspects of pathogenesis. Among CXC chemokines, single nucleotide polymorphisms (SNPs) in the CXCL8 and CXCL12 genes stand out, as they have alleles associated with many diseases such as asthma and human immunodeficiency virus (HIV), respectively. Of CC chemokines, the stronger associations occur among alleles from SNPs in CCL2 and CCL5 genes and a number of inflammatory conditions. To understand how chemokines contribute to disease it is also necessary to take into account all the isoforms resulting from differential splicing. The first part of this review deals with polymorphisms and the second with the diversity of molecular species derived from each chemokine gene due to alternative splicing phenomena. The number of molecular species and the level of expression of each of them for every chemokine and for each functionally related group of chemokines reaches a complexity that requires new modelling algorithms akin to those proposed in systems biology approaches.

Abstract
gp130-linked cytokines such as interleukin-6 (IL-6) stimulate the formation of tyrosine-phosphorylated signal transducer and activator of transcription 3 (P-STAT3), which activates many genes, including the STAT3 gene itself. The resulting increase in the concentration of unphosphorylated STAT3 (U-STAT3) drives a second wave of expression of genes such as RANTES, IL6, IL8, MET, and MRAS that do not respond directly to P-STAT3. Thus, U-STAT3 sustains cytokine-dependent signaling at late times through a mechanism completely distinct from that used by P-STAT3. Many U-STAT3-responsive genes have kappaB elements that are activated by a novel transcription factor complex formed when U-STAT3 binds to unphosphorylated NFkappaB (U-NFkappaB), in competition with IkappaB. The U-STAT3/U-NFkappaB complex accumulates in the nucleus with help from the nuclear localization signal of STAT3, activating a subset of kappaB-dependent genes. Additional genes respond to U-STAT3 through an NFkappaB-independent mechanism. The role of signal-dependent increases in U-STAT3 expression in regulating gene expression is likely to be important in physiological responses to gp130-linked cytokines and growth factors that activate STAT3, and in cancers that have constitutively active P-STAT3.

Abstract
It has been reported that a functional polymorphism in the promoter of the RANTES gene (-403G/A) is associated with atopic dermatitis in a German population. Although there are several reports on the association of RANTES promoter polymorphisms (-403G/A and -28C/G) with asthma, the association of these polymorphisms with atopic dermatitis has not yet been confirmed in other populations. We therefore aimed to test whether the RANTES promoter polymorphisms relate to atopic dermatitis in a well-defined Japanese population. We conducted an association study of upregulating promoter polymorphisms of RANTES (-403G/A and -28C/G) in 389 patients with atopic dermatitis and 177 healthy control subjects. There was a significant association between the upregulating variant of RANTES -28G and atopic dermatitis, while -403A variant showed a significant association with atopic dermatitis with high IgE productivity. These results support a role for RANTES promoter polymorphisms in susceptibility to atopic dermatitis.

Abstract
The IL-4 receptor (IL-4R) and IL-13 genes are candidate genes in atopic diseases. The IL-4Ralpha chain and IL-13 promoter polymorphisms are gain-of-function mutations associated with atopy. We tested whether polymorphisms in the IL-4Ralpha chain and the coding region of the IL-13 gene are associated with allergic rhinitis in a Korean population. Polymerase chain reaction-based assays for IL-4Ralpha Gln551Arg and IL-13 exon 4 G2044A were used for genotyping. There were no differences in the frequencies of the genotypes and alleles of IL-4Ralpha between the controls and patients. The frequency of the IL-13 exon 4 2044A allele was statistically different between the controls and patients. Our results suggest that the IL-13 exon 4 G2044A polymorphism confers susceptibility to the development of allergic rhinitis in Koreans, whereas the IL-4Ralpha Gln551Arg polymorphism is not related to allergic rhinitis.

Abstract
PURPOSE OF REVIEW This article will focus on the role of risk factors including genetic factors in the development of sensitization and occupational asthma. RECENT FINDINGS We will review the recent literature published on the genetics of occupational asthma, especially on genes coding for class II human leukocyte antigen and on respiratory antioxidant mechanisms. We will also discuss published work on non-occupational asthma and on allergic rhinitis because this information may contribute to a better understanding of the mechanisms involved in occupational asthma and serve to confirm data obtained on the disease. To date, although some progress has been made in the field of occupational asthma genetics, most studies were based on small sample sizes, findings were not replicated, and gene-environment interactions have not yet been established. SUMMARY Occupational asthma is a widespread and frequent condition and has relevant long-term adverse health and economic consequences. The search for risk factors including genetic factors in the development of the disease and an understanding of the mechanisms of interaction between genes and environment are important because the identification of individuals who are susceptible to occupational asthma together with an effective control of exposure to respiratory sensitizers in the workplace may be helpful in preventing the disease.
