Abstract
IFN-λ or type III IFN is an important mediator of antiviral response. Several respiratory viruses induce the production of IFN-λ during their course of infection. However, they have also developed intricate mechanisms to inhibit its expression and activity. Despite a considerable amount of research on the regulatory mechanisms of respiratory viruses on the IFN-λ response, little is still known about the effect of this cytokine on immune cells and the antiviral effects of all IFN-λ isoforms, and a better understanding of the detrimental effects of IFN-λ treatment is required. Here we highlight the relevance of IFN-λ as an antiviral cytokine in the respiratory tract. Data from studies in vitro, ex vivo, experimental animal models, and ongoing clinical trials emphasize the therapeutic opportunity that IFN-λ represents to treat and prevent different types of respiratory viral infections.

Abstract
Here we investigate the function of the innate immune molecule protein kinase R (PKR) in intestinal inflammation. To model a colitogenic role of PKR, we determine the physiological response to dextran sulfate sodium (DSS) of wild-type and two transgenic mice strains mutated to express either a kinase-dead PKR or to ablate expression of the kinase. These experiments recognize kinase-dependent and -independent protection from DSS-induced weight loss and inflammation, against a kinase-dependent increase in the susceptibility to DSS-induced injury. We propose these effects arise through PKR-dependent alteration of gut physiology, evidenced as altered goblet cell function and changes to the gut microbiota at homeostasis that suppresses inflammasome activity by controlling autophagy. These findings establish that PKR functions as both a protein kinase and a signaling molecule in instituting immune homeostasis in the gut.

Identification of a lncRNA AC011511.5- Mediated Competitive Endogenous RNA Network Involved in the Pathogenesis of Allergic Rhinitis. Front Genet 2022; 13:811679. [PMID: 35711945 PMCID: PMC9194448 DOI: 10.3389/fgene.2022.811679] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2021] [Accepted: 05/05/2022] [Indexed: 11/13/2022] Open
Abstract
LncRNA-miRNA-mRNA competing endogenous RNA (ceRNA) networks are thought to be involved in regulating the development of various inflammatory diseases. Up to now, the mechanism of such a network in allergic rhinitis (AR) remains unclear. In the study, we investigated the differential expression of lncRNAs (DElncRNAs) and mRNAs (DEmRNAs) by performing a microarray analysis of peripheral blood obtained from AR patients and healthy control subjects. StarBase 2.0 was used to predict miRNAs that might interact with various DElncRNAs and DEmRNAs. We constructed a ceRNA network based on potential lncRNA-miRNA-mRNA interactions. The Cluster Profiler R package was used to perform a functional enrichment analysis of the hub-ceRNA, and Molecular Complex Detection (MCODE) was used for further identification of the hub-ceRNA network. The expression levels of genes contained in the hub-ceRNA network were validated by RT-PCR. In total, 247 DEmRNAs and 18 DelncRNAs were aberrantly expressed in the PBMCs of AR patients. A ceRNA network consisting of 3 lncRNAs, 45 miRNAs, and 75 mRNAs was constructed. A GO analysis showed that negative regulation of immune response, response to interferon-beta, and response to interferon-alpha were important terms. A KEGG pathway analysis showed that 75 mRNAs were significantly enriched in "NOD-like receptor signaling pathway" and "tryptophan metabolism". Ultimately, a hub-ceRNA network was constructed based on 1 lncRNA (AC011511.5), 5 miRNAs (hsa-miR-576-5p, hsa-miR-520c-5p, hsa-miR-519b-5p, hsa-miR-519c-5p, and hsa-miR-518d-5p), and 2 mRNAs (ZFP36L1 and SNX27). Following further verification, we found that overexpression of lncRNA AC011511.5 or inhibitor of miR-576-5p upregulated SNX27 expression. The expression of SNX27 in the lncRNA AC011511.5 overexpression & miR-576-5p inhibitor group was not different from that in the miR-576-5p inhibitor group or lncRNA AC011511.5 overexpression group, indicating that overexpression of lncRNA AC011511.5 could not further upregulate the expression of SNX27 in miR-576-5p inhibitor Jurkat cells. This network may provide new insights to search for biomarkers that can be used for the diagnosis and clinical treatment of AR.

Abstract
UNLABELLED Patients with allergic rhinitis (AR) have a predisposition to frequent acute respiratory viral infections (ARVI). Inflammation of the mucous membrane of the nasal cavity and paranasal sinuses in such patients is more pronounced against the background of a combination of allergic and infectious inflammation. OBJECTIVE To evaluate the effect of therapy using modern antihistamines on the condition and severity of symptoms in adult patients with exacerbation of AR caused by plant pollen (seasonal) (SAR) and the development of ARVI. MATERIAL AND METHODS An observational study was conducted at the Department of Otorhinolaryngology of the Evdokimov Moscow State University of Medicine and Dentistry of the Ministry of Health of the Russian Federation from April to August 2021. Included are patients of both sexes aged 18 to 65 years with a previously (at least 1 year ago) verified diagnosis of mild and moderate acute SAR in the acute stage, who sought medical help for ARVI. All patients were prescribed therapy with the inclusion of a drug belonging to the pharmacological group of antihistamines of the 2nd generation (a course of 14 days). In addition, patients received symptomatic ARVI therapy according to indications, including nasal decongestants (as needed), antipyretic and antitussive drugs. RESULTS Based on the data obtained, it was possible to prove that the use of modern antihistamines in patients comorbid with AR and ARVI has a pronounced therapeutic effect. Theoritin provides a therapeutic effect at an early stage in relation to nasal and non-nasal symptoms of SAR/ARVI, and also quickly improves the quality of life of patients, which makes its use promising for the treatment of ARVI against the background of AR. The drug has an antihistamine activity comparable to cetirizine and surpasses it in its ability to suppress an allergic inflammatory reaction, for example on the skin, as well as in the duration of preservation of the antihistamine effect. CONCLUSION The presented results indicate the effectiveness of theoritin and cetirizine in the treatment of patients with seasonal exacerbation of allergic rhinitis, comorbid for acute respiratory viral infections.

Abstract
AIMS Notch signaling is closely related to a variety of diseases, but the role of Notch2 in allergic rhinitis (AR) remain unclear. This study was performed to investigate the effects of Notch2 on the differentiation of Treg cells and on the inflammatory response of AR. MATERIALS AND METHODS Peripheral blood (including 101 AR patients and 66 Controls) and nasal mucosa (including 19 AR patients and 17 Controls) were collected to detect the expression levels of Notch2, NICD2 and FOXP3. CD4+ T cells of human origin were selected to detect the effects of Notch2 on the differentiation of Treg cells and FOXP3. An AR mouse model was established, and lentiviruses overexpressing Notch2 were administered. Then, allergic symptoms, OVA-sIgE titers, nasal mucosal inflammation, Th1/Th2/Th17 cytokines and splenic Treg cells were assessed. KEY FINDINGS Compared with that in the Control group, the expression of Notch2 in the AR group was decreased, and Notch2 expression was negatively correlated with the degree of allergy (P < 0.01). The expression levels of Notch2, NICD2 and FOXP3 were decreased in the nasal mucosa of AR patients. Notch2 can promote the differentiation of human Treg cells in vitro (P < 0.05), and Notch2 can directly promote FOXP3 transcription. Animal experiments showed after the upregulation of Notch2 expression, the allergic inflammatory of mice with AR was reduced, the differentiation of Treg cells was increased, and the imbalance of T cells was reversed (P < 0.05). SIGNIFICANCE Notch2 promotes the differentiation of Treg cells by upregulating FOXP3 expression, thus significantly inhibiting the inflammatory response of AR.

Abstract
There is a limited number of clinical studies on interferon (IFN) levels in human brucellosis. The novel group of interferons, type III interferons, which consists of four IFN-λ (lambda) molecules called IFN-λ1 or interleukin-29 (IL-29), IFN-λ2 or IL-28A, IFN-λ3 or IL-28B, and IFN-λ4, is not fully known. This study is one of the first studies of IL-28A and IL-29 levels in brucellosis cases at the end of their treatment course. A total of 33 acute brucellosis patients were included in this study. We considered changes in the levels of IL-28A and IL-29 in cases with acute brucellosis before and after treatment with standard therapy that referred to the Ayatollah Rohani Hospital in Babol, northern Iran. Of 33 included patients, 22 (66.6%) were males, and 11 (33.4%) were females. The range of patients' age was 49.21 ± 17.70 years. Serum IL-29 and IL-28A (acute form: 56.4 ± 30.32 pg/mL and 48.73 ± 27.72 pg/mL, respectively, and posttreatment: 40.15 ± 20.30 pg/mL and 38.79 ± 22.66 pg/mL, respectively) levels were elevated significantly in acute brucellosis than after treatment (p < 0.05). These findings indicate that considering biomarker levels in brucellosis patients may indicate the chronicity of infection. In conclusion, we suggest that IL-29 and IL-28A levels may be valuable biomarkers for follow-up patients with brucellosis.

Abstract
Modern health care requires a proactive and individualized response to diseases, combining precision diagnosis and personalized treatment. Accordingly, the approach to patients with allergic diseases encompasses novel developments in the area of personalized medicine, disease phenotyping and endotyping, and the development and application of reliable biomarkers. A detailed clinical history and physical examination followed by the detection of IgE immunoreactivity against specific allergens still represents the state of the art. However, nowadays, further emphasis focuses on the optimization of diagnostic and therapeutic standards and a large number of studies have been investigating the biomarkers of allergic diseases, including asthma, atopic dermatitis, allergic rhinitis, food allergy, urticaria and anaphylaxis. Various biomarkers have been developed by omics technologies, some of which lead to a better classification of distinct phenotypes or endotypes. The introduction of biologicals to clinical practice increases the need for biomarkers for patient selection, prediction of outcomes and monitoring, to allow for an adequate choice of the duration of these costly and long‐lasting therapies. Escalating healthcare costs together with questions about the efficacy of the current management of allergic diseases require further development of a biomarker‐driven approach. Here, we review biomarkers in diagnosis and treatment of asthma, atopic dermatitis, allergic rhinitis, viral infections, chronic rhinosinusitis, food allergy, drug hypersensitivity and allergen immunotherapy with a special emphasis on specific IgE, the microbiome and the epithelial barrier. In addition, EAACI guidelines on biologicals are discussed within the perspective of biomarkers.

Abstract
Interferons (IFN) are crucial for the innate immune response. Slightly more than two decades ago, a new type of IFN was discovered: the lambda IFN (type III IFN). Like other IFN, the type III IFN display antiviral activity against a wide variety of infections, they induce expression of antiviral, interferon-stimulated genes (MX1, OAS, IFITM1), and they have immuno-modulatory activities that shape adaptive immune responses. Unlike other IFN, the type III IFN signal through distinct receptors is limited to a few cell types, primarily mucosal epithelial cells. As a consequence of their greater and more durable production in nasal and respiratory tissues, they can determine the outcome of respiratory infections. This review is focused on the role of IFN-λ in the pathogenesis of respiratory viral infections, with influenza as a prime example. The influenza virus is a major public health problem, causing up to half a million lethal infections annually. Moreover, the virus has been the cause of four pandemics over the last century. Although IFN-λ are increasingly being tested in antiviral therapy, they can have a negative influence on epithelial tissue recovery and increase the risk of secondary bacterial infections. Therefore, IFN-λ expression deserves increased scrutiny as a key factor in the host immune response to infection.

Symbiotic microbiome Staphylococcus aureus from human nasal mucus modulates IL-33-mediated type 2 immune responses in allergic nasal mucosa. BMC Microbiol 2020; 20:301. [PMID: 33028252 PMCID: PMC7542126 DOI: 10.1186/s12866-020-01974-6] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2020] [Accepted: 09/10/2020] [Indexed: 12/15/2022] Open
Abstract
Background The host-microbial commensalism can shape the innate immune responses in respiratory mucosa and nasal microbiome also modulates front-line immune mechanism in the nasal mucosa. Inhaled allergens encounter the host immune system first in the nasal mucosa, and microbial characteristics of nasal mucus directly impact the mechanisms of initial allergic responses in nasal epithelium. However, the roles of the nasal microbiome in allergic nasal mucosa remain uncertain. We sought to determine the distribution of nasal microbiomes in allergic nasal mucosa and elucidate the interplay between nasal microbiome Staphylococcus species and Th2 cytokines in allergic rhinitis (AR) models. Results Staphylococcus aureus (AR-SA) and S. epidermidis (AR-SE) were isolated from the nasal mucosa of patients with AR. The influence of nasal microbiome Staphylococcus species on allergic nasal mucosa was also tested with in vitro and in vivo AR models. Pyrosequencing data showed that colonization by S. epidermidis and S. aureus was more dominant in nasal mucus of AR subjects. The mRNA and protein levels of IL-33 and TSLP were significantly higher in AR nasal epithelial (ARNE) cells which were cultured from nasal mucosa of AR subjects, and exposure of ARNE cells to AR-SA reduced IL-33 mRNA and secreted protein levels. Particularly, ovalbumin-driven AR mice inoculated with AR-SA by intranasal delivery exhibited significantly reduced IL-33 in their nasal mucosa. In the context of these results, allergic symptoms and Th2 cytokine levels were significantly downregulated after intranasal inoculation of AR-SA in vivo AR mice. Conclusion Colonization by Staphylococcus species was more dominant in allergic nasal mucosa, and nasal commensal S. aureus from subjects with AR mediates anti-allergic effects by modulating IL-33-dependent Th2 inflammation. The results demonstrate the role of host-bacterial commensalism in shaping human allergic inflammation.

Abstract
Middle East Respiratory Syndrome Coronavirus (MERS-CoV) causes severe respiratory in human with high mortality and it has been a challenge to determine optimum treatment for MERS-CoV-induced respiratory infection. Here, we observed the distribution of MERS-CoV receptors using human respiratory mucosa and also evaluated the contribution of interferon-lambdas (IFN-λs) in response to MERS-CoV infection using in vitro normal human nasal epithelial (NHNE) and bronchial epithelial (NHBE) cells. We found that the gene and protein expression of DPPIV, MERS-CoV receptor, were more dominantly located in nasal and bronchial epithelium although human nasal mucosa exhibited relatively lower DPPIV expression than lung parenchymal tissues. The quantitative mRNA level of the MERS-CoV envelope (upE) gene was significantly induced in MERS-CoV-infected cultured NHNE and NHBE cells until 3 days after infection. The induction of IFNs was identified in NHNE and NHBE cells after MERS-CoV infection and IFN-λs were predominantly increased in MERS-CoV-infected respiratory epithelial cells. Inoculation of IFN-λs to NHNE and NHBE cells suppressed MERS-CoV replication and in particular, IFN-λ4 showed a strong therapeutic effect in reducing MERS-CoV infection with higher induction of IFN-stimulated genes. Thus, IFN-λ has a decisive function in the respiratory epithelium that greatly limits MERS-CoV replication, and may be a key cytokine for better therapeutic outcomes against MERS-CoV infection in respiratory tract.

Abstract
Porcine deltacoronavirus (PDCoV) is a novel swine enteropathogenic coronavirus that causes watery diarrhea, vomiting and mortality in nursing piglets. Type III interferons (IFN-λs) are the major antiviral cytokines in intestinal epithelial cells, the target cells in vivo for PDCoV. In this study, we found that PDCoV infection remarkably inhibited Sendai virus-induced IFN-λ1 production by suppressing transcription factors IRF and NF-κB in IPI-2I cells, a line of porcine intestinal mucosal epithelial cells. We also confirmed that PDCoV infection impeded the activation of IFN-λ1 promoter stimulated by RIG-I, MDA5 and MAVS, but not by TBK1 and IRF1. Although the expression levels of IRF1 and MAVS were not changed, PDCoV infection resulted in reduction of the number of peroxisomes, the platform for MAVS to activate IRF1, and subsequent type III IFN production. Taken together, our study demonstrates that PDCoV suppresses type III IFN responses to circumvent the host's antiviral immunity.

HCV and flaviviruses hijack cellular mechanisms for nuclear STAT2 degradation: Up-regulation of PDLIM2 suppresses the innate immune response. PLoS Pathog 2019; 15:e1007949. [PMID: 31374104 PMCID: PMC6677295 DOI: 10.1371/journal.ppat.1007949] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2018] [Accepted: 06/29/2019] [Indexed: 12/22/2022] Open
Abstract
Host encounters with viruses lead to an innate immune response that must be rapid and broadly targeted but also tightly regulated to avoid the detrimental effects of unregulated interferon expression. Viral stimulation of host negative regulatory mechanisms is an alternate method of suppressing the host innate immune response. We examined three key mediators of the innate immune response: NF-KB, STAT1 and STAT2 during HCV infection in order to investigate the paradoxical induction of an innate immune response by HCV despite a multitude of mechanisms combating the host response. During infection, we find that all three are repressed only in HCV infected cells but not in uninfected bystander cells, both in vivo in chimeric mouse livers and in cultured Huh7.5 cells after IFNα treatment. We show here that HCV and Flaviviruses suppress the innate immune response by upregulation of PDLIM2, independent of the host interferon response. We show PDLIM2 is an E3 ubiquitin ligase that also acts to stimulate nuclear degradation of STAT2. Interferon dependent relocalization of STAT1/2 to the nucleus leads to PDLIM2 ubiquitination of STAT2 but not STAT1 and the proteasome-dependent degradation of STAT2, predominantly within the nucleus. CRISPR/Cas9 knockout of PDLIM2 results in increased levels of STAT2 following IFNα treatment, retention of STAT2 within the nucleus of HCV infected cells after IFNα stimulation, increased interferon response, and increased resistance to infection by several flaviviruses, indicating that PDLIM2 is a global regulator of the interferon response. The response of cells to an invading pathogen must be swift and well controlled because of the detrimental effects of chronic inflammation. However, viruses often hijack host control mechanisms. HCV and flaviviruses are known to suppress the innate immune response in cells by a variety of mechanisms. This study clarifies and expands a specific cellular mechanism for global control of the antiviral response after the induction of interferon expression. It shows how several viruses hijack this control mechanism to suppress the innate interferon response.
