Int J Mol Sci 2024; 25:5972. [PMID: 38892164 PMCID: PMC11172531 DOI: 10.3390/ijms25115972] [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: 02/20/2024] [Revised: 05/20/2024] [Accepted: 05/24/2024] [Indexed: 06/21/2024] Open
Abstract
Thymic stromal lymphopoietin (TSLP), is a protein belonging to a class of epithelial cytokines commonly called alarmins, which also includes IL-25 and IL-33. Functionally, TSLP is a key player in the immune response to environmental insults, initiating a number of downstream inflammatory pathways. TSLP performs its role by binding to a high-affinity heteromeric complex composed of the thymic stromal lymphopoietin receptor (TSLPR) chain and IL-7Rα. In recent years, the important role of proinflammatory cytokines in the etiopathogenesis of various chronic diseases such as asthma, chronic rhinosinusitis with nasal polyposis (CRSwNP), chronic obstructive pulmonary diseases (COPDs), and chronic spontaneous urticaria has been studied. Although alarmins have been found to be mainly implicated in the mechanisms of type 2 inflammation, studies on monoclonal antibodies against TSLP demonstrate partial efficacy even in patients whose inflammation is not definable as T2 and the so-called low T2. Tezepelumab is a human anti-TSLP antibody that prevents TSLP-TSLPR interactions. Several clinical trials are evaluating the safety and efficacy of Tezepelumab in various inflammatory disorders. In this review, we will highlight major recent advances in understanding the functional role of TSLP, its involvement in Th2-related diseases, and its suitability as a target for biological therapies.

Abstract
Disruption of the airway epithelium triggers a defensive immune response that begins with the production and release of alarmin cytokines. These epithelial-derived alarmin cytokines, including thymic stromal lymphopoietin (TSLP), are produced in response to aeroallergens, viruses, and toxic inhalants. An alarmin response disproportionate to the inhaled trigger can exacerbate airway diseases such as asthma. Allergens inhaled into previously sensitized airways are known to drive a T2 inflammatory response through the polarization of T cells by dendritic cells mediated by TSLP. Harmful compounds found within air pollution, microbes, and viruses are also triggers causing airway epithelial cell release of TSLP in asthmatic airways. The release of TSLP leads to the development of inflammation which, when unchecked, can result in asthma exacerbations. Genetic and inheritable factors can contribute to the variable expression of TSLP and the risk and severity of asthma. This paper will review the various triggers and consequences of TSLP release in asthmatic airways.

Abstract
Natural killer T (NKT) cells are innate-like T lymphocytes that recognize glycolipid antigens rather than peptides. Due to their immunoregulatory properties, extensive work has been done to elucidate the immune functions of NKT cells in various immune contexts such as autoimmunity for more than two decades. In addition, as research on barrier immunity such as the mucosa-associated lymphoid tissue has flourished in recent years, the role of NKT cells to immunity in the skin has attracted substantial attention. Here, we review the contributions of NKT cells to regulating skin inflammation and discuss the factors that can modulate the functions of NKT cells in inflammatory skin diseases such as atopic dermatitis. This mini-review article will mainly focus on CD1d-dependent NKT cells and their therapeutic potential in skin-related immune diseases.

The Role of Airway Epithelial Cell Alarmins in Asthma. Cells 2022; 11:cells11071105.

Abstract
The airway epithelium is the first line of defense for the lungs, detecting inhaled environmental threats through pattern recognition receptors expressed transmembrane or intracellularly. Activation of pattern recognition receptors triggers the release of alarmin cytokines IL-25, IL-33, and TSLP. These alarmins are important mediators of inflammation, with receptors widely expressed in structural cells as well as innate and adaptive immune cells. Many of the key effector cells in the allergic cascade also produce alarmins, thereby contributing to the airways disease by driving downstream type 2 inflammatory processes. Randomized controlled clinical trials have demonstrated benefit when blockade of TSLP and IL-33 were added to standard of care medications, suggesting these are important new targets for treatment of asthma. With genome-wide association studies demonstrating associations between single-nucleotide polymorphisms of the TSLP and IL-33 gene and risk of asthma, it will be important to understand which subsets of asthma patients will benefit most from anti-alarmin therapy.

Gardenia jasminoides extract ameliorates DfE-induced atopic dermatitis in mice through restoration of barrier function and T-helper 2-mediated immune response. Biomed Pharmacother 2021; 145:112344.

Abstract
Atopic dermatitis (AD) leads to skin barrier abnormalities and immune dysfunction. As the topical steroids commonly used to treat AD have side effects from long-term use, research into safer treatments for AD is greatly needed. The medicinal herb Gardenia jasminoides improves AD symptoms via skin barrier activation and T helper 2-mediated immune response regulation. Crocin, a bioactive component within the extract, is dispensible for its restorative effects. As such, this work explored the effects of Gardenia jasminoides extract without crocin (GjexCr) on AD symptoms in a DfE-induced AD model in 6-week-old male NC/Nga mice (25.0 ± 0.25 g, n = 10 each, 6 groups). Using histological and behavioral assays, the effects of GjexCr on dermatitis scores, scratching behavior, skin barrier activation, and serum levels of IgE, chemokines, and cytokines were analyzed. In addition, the major components from the GjexCr extract were analyzed by high-performance liquid chromatography and validated in the AD model. GjexCr reduced ear thickness due to hyperkeratosis, dermal thickening, and scratching behavior and restored dermatitis scores in AD-induced mice. GjexCr administration also decreased inflammation and mast cell infiltration, as well as modulated skin barrier recovery by upregulating the production of epidermal proteins. Moreover, GjexCr administration attenuated imbalanced immune responses. Furthermore, geniposide, the main component of GjexCr, improved AD symptoms in DfE-treated NC/Nga mice. Thus, GjexCr could be a suitable treatment for protecting the skin barrier in AD-like skin lesions and a potential therapy for AD.

Abstract
Background Invariant natural killer T (iNKT) cells are known as the fast responder in allergic inflammation and the source of interleukin (IL)-4, IL-13, and interferon-gamma. Absence of iNKT cells down-regulated thymic stromal lymphopoietin (TSLP) production at the early stage of type 2 immune responses in the airway. However, it has not been reported whether iNKT cells are able to produce TSLP via stimulation of T-cell receptor (TCR). Objective We aimed to evaluate TSLP production from iNKT cells by TCR specific stimulations with anti-CD3/CD28 antibodies and α-galactoceramide (α-GalCer). Methods DN32.D3 iNKT cell line was stimulated with anti-CD3/CD28 antibodies, and TSLP production was measured in culture supernatants. Next, to confirm the TSLP production in primary mouse iNKT cells, the cells were sorted using α-GalCer-CD1d tetramer from mouse liver, and stimulated with anti-CD3/CD28 antibodies and α-GalCer. Then, cytokine productions were evaluated by enzyme-linked immunosorbent assay and quantitative polymerase chain reaction. Results TCR specific stimulation in DN32.D3 cells induced TSLP production as well as signature cytokines of iNKT cells. On the other hand, isolated primary mouse iNKT cells from liver did not show any induction of TSLP by TCR specific stimulations including anti-CD3/CD28 antibodies and α-GalCer, on the contrary to other cytokines. Conclusion This study suggested the possibility of TSLP production in iNKT cells, especially from DN32.D3 although primary mouse liver iNKT cells showed a different result.

Abstract
BACKGROUND Natural killer T (NKT) cells are unconventional T cells that bridge innate and adaptive immunity. NKT cells have been implicated in the development of atopic dermatitis (AD). OBJECTIVE We aimed to investigate the role of NKT cells in AD development, especially in skin. METHODS Global proteomic and transcriptomic analyses were performed by using skin and blood from human healthy-controls and patients with AD. Levels of CXCR4 and CXCL12 expression in skin NKT cells were analyzed in human AD and mouse AD models. By using parabiosis and intravital imaging, the role of skin CXCR4+ NKT cells was further evaluated in models of mice with AD by using CXCR4-conditionally deficient or CXCL12 transgenic mice. RESULTS CXCR4 and its cognate ligand CXCL12 were significantly upregulated in the skin of humans with AD by global transcriptomic and proteomic analyses. CXCR4+ NKT cells were enriched in AD skin, and their levels were consistently elevated in our models of mice with AD. Allergen-induced NKT cells participate in cutaneous allergic inflammation. Similar to tissue-resident memory T cells, the predominant skin NKT cells were CXCR4+ and CD69+. Skin-resident NKT cells uniquely expressed CXCR4, unlike NKT cells in the liver, spleen, and lymph nodes. Skin fibroblasts were the main source of CXCL12. CXCR4+ NKT cells preferentially trafficked to CXCL12-rich areas, forming an enriched CXCR4+ tissue-resident NKT cells/CXCL12+ cell cluster that developed in acute and chronic allergic inflammation in our models of mice with AD. CONCLUSIONS CXCR4+ tissue-resident NKT cells may form a niche that contributes to AD, in which CXCL12 is highly expressed.

Abstract
BACKGROUND Low vitamin D levels have been associated with allergic diseases. Vitamin D has potent immunomodulatory properties, but the mechanisms remain unclear. We have investigated the effect of oral vitamin D supplementation on circulating immune cell phenotypes in infants. METHOD A double-blinded randomised controlled trial was conducted to investigate the effect of oral vitamin D supplementation (400 IU/d) on eczema and immune development. A subset of 78 infants was included in this analysis. Phenotypic analysis of immune cell subsets was performed using flow cytometry. RESULTS Vitamin D supplementation resulted in median 25(OH)D levels of 80.5 vs 59.5 nmol/L in the placebo group at 3 months of age (P = .002) and 87.5 vs 77 nmol/L at 6 months of age (P = .08). We observed significant changes in immune cell composition from birth (cord blood) to 6 months of age. Vitamin D supplementation did not impact these changes, nor did immune cell composition correlate with plasma 25(OH)D levels. Through exploratory analysis, we identified possible associations with eczema development and increased abundance of naïve CD4- T cells at birth, as well as associations with basophils, iNKT and central memory CD4+ T cells, and altered expression patterns of IgE receptor (FcεR1) on monocytes and dendritic cells with eczema at 6 months. CONCLUSIONS Vitamin D supplementation in infants who were vitamin D sufficient at birth did not affect developmental changes in immune cells during the first 6 months of life. However, immune cell profiles at birth and at 6 months of age were associated with early life eczema.

Abstract
BACKGROUND Atopic dermatitis (AD) pathogenesis still needs to be elucidated, but invariant natural killer T (iNKT) cell involvement was already described by several groups. Our group has demonstrated that IgG antibodies purified from AD patients can modulate cytokine production by thymic T cells. Here we aimed to investigate if IgG from AD patients can modulate infant non-atopic thymic iNKT cells cytokine production in order to collaborate with the elucidation of AD development in infancy. METHODS Thymic tissues were obtained from children from non-atopic mothers, and IgG was purified from AD patients diagnosed as moderate or severe and, as controls, from subjects clinically classified as non-atopic individuals. PBMCs from non-atopic individuals were also used in this study. RESULTS Our results demonstrated that IgG from AD patients could induce non-atopic children thymic iNKT cells to produce higher levels of intracellular IL-4, IL-10, and IL-17 when compared to all control conditions. No effect was observed in non-atopic adults peripheral iNKT. We also observed that IgG from AD patients induces an increase in the expression of CD4 and Rorγt transcription factor in non-atopic children thymic iNKT cells compared to the condition of all controls. CONCLUSIONS These observations suggest that IgG from AD patients can induce a cytokine profile by thymic iNKT cells from non-atopic infants compatible with the observations in AD development, which can collaborate with the elucidation of AD pathogenesis.

Abstract
BACKGROUND Thymic stromal lymphopoietin (TSLP) mediates proallergic T helper 2-type responses by acting on leucocytes. Endogenous pathways regulating TSLP production are poorly defined. OBJECTIVES To uncover the mechanisms by which skin barrier disruption elicits TSLP production and to delineate the level at which individual mechanistic components may converge. METHODS A combination of primary keratinocytes, skin explants and in vivo strategies was employed. Murine skin was tape stripped in the presence of neutralizing antibodies or antagonists. Cells and explants were stimulated with interleukin (IL)-1 and protease-activated receptor 2 agonist (PAR-2-Ag). TSLP levels were quantified by enzyme-linked immunosorbent assay and real-time quantitative polymerase chain reaction. Chromatin immunoprecipitation and promoter reporter assays were used to examine recruitment and functional activity of nuclear factor kappa B (NF-κB) at the TSLP promoter. RESULTS TSLP induction in mouse skin occurred in a PAR-2- and IL-1-dependent manner. This scenario was duplicated by exogenous IL-1 plus PAR-2-Ag vs. each stimulus alone. Joint activity of PAR-2 and IL-1 was also observed in human keratinocytes. The TSLP promoter was identified as the target of PAR-2/IL-1, whereby PAR-2 activation augmented the recruitment of NF-κB and transcriptional activation over IL-1 alone. Combined treatment showed activity at concentrations of IL-1 unable to elicit NF-κB activity on their own. CONCLUSIONS Skin barrier disruption activates the IL-1 and the PAR-2 pathways, which act in concert to activate the TSLP promoter and possibly other inflammatory genes. Awareness of this combined activity may permit a more flexible clinical management by selective targeting of either pathway individually or collectively. What's already known about this topic? Thymic stromal lymphopoietin (TSLP) is rapidly induced upon skin perturbation and mediates proallergic T helper 2-type responses by acting on leucocytes. Endogenous control of TSLP expression is poorly understood, but interleukin (IL)-1 is one regulator in the cutaneous environment In addition to IL-1, protease-activated receptor 2 (PAR-2) organizes central inflammatory pathways in the skin. What does this study add? IL-1 and PAR-2 pathways cooperate in driving TSLP production in mice and humans. Pathway integration occurs at the level of the TSLP promoter through enhanced recruitment and transcriptional activation of nuclear factor kappa B. When PAR-2 is co-stimulated, very low IL-1 levels (inactive by themselves) can induce biologically meaningful responses in the skin environment. What is the translational message? Physical skin irritation results in robust TSLP production by simultaneous activation of PAR-2 and IL-1 pathways.

Abstract
Nasal polyps (NP) are associated with inflamed mucosa of unknown etiology. The role of T cells in nasal polyposis is unclear. Invariant natural killer T cells (iNKT) can promote Th2 responses and have been implicated in some types of asthma. As there are shared inflammatory pathways involved in asthma and NPs, we evaluated the frequency of iNKT in 17 patients with NPs, but without asthma. A median of 6% polyp cells were T lymphocytes, of which iNKT were 0 to 2.38% (mean 0.674%). In the matched group (n = 10), iNKT in NPs was significantly higher than PBMCs (1.057% vs 0.155%, P < 0.05). Relative expression of Vα24 to TCR-beta genes in polyps (n = 14) was higher than blood in matched samples (n = 4). The presence of greater proportions of iNKT in NPs than in blood suggests that iNKT may play a role in the pathogenesis of nasal polyposis.

Abstract
Invariant and semi-invariant T cells are emerging as important regulators of host environment interactions at barrier tissues such as the airway and skin. In contrast to conventional T cells, invariant natural killer T (iNKT) cells and mucosal associated invariant T (MAIT) cells express T cell receptors of very limited diversity. iNKT and MAIT cells recognise antigens presented by the MHC class 1-like monomorphic molecules CD1d and MR1, respectively. Both iNKT cells and MAIT cells have been identified in the skin and airways and can rapidly produce cytokines after activation. Numerous studies have implicated iNKT cells in the pathology of both skin and airway disease, but conflicting evidence in human disease means that more studies are necessary to resolve the exact roles of iNKT in inflammation. The functions of MAIT cells in skin and lung inflammation are even less well defined. We herein describe the current literature on iNKT and MAIT cells in allergic and non-allergic skin diseases (dermatitis and psoriasis) and airway diseases (asthma, chronic obstructive pulmonary disease, rhinitis, and chronic rhinosinusitis).

Abstract
Thymic stromal lymphopoietin is a key initiator for inducing Th2-type inflammation and a potential therapeutic target for allergic disease. In the present study, the naive human antibody library was enriched using human thymic stromal lymphopoietin (hTSLP) as an antigen by phage display. Single clones were randomly picked from the enriched antibody library after three rounds of selection, and these were expressed for enzyme-linked immunosorbent assay (ELISA). The positive single-chain fragment variables (scFvs) determined by ELISA were further identified by Western blot, Biacore, and flow cytometry. After three rounds of phage display, 35% of the scFv clones were positive by ELISA and could bind well with hTSLP. Further identification revealed that scFv29 had satisfactory characteristics. The scFv29 was specific to hTSLP, and had no cross-reaction with hIL-33, hIL-4, and hIL-13. The scFv29 could bind to hTSLP in competition with the TSLP receptor and could also bind to mouse TSLP. Cellular experiments revealed that mTSLP could stimulate myeloid dendritic cell (DC) to mature, and scFv29 blocking could reduce the maturation rate of DC. These findings suggest that scFv29 could be used as a neutralizing antibody to block the signaling of TSLP, and this work provides the foundation for further study of the therapeutic roles of TSLP in allergic inflammation diseases.

Abstract
BACKGROUND AND PURPOSE Atopic dermatitis (AD) is a multifactorial skin condition with complex interactions of innate and adaptive immune responses. There are several existing therapies for AD, including topical glucocorticosteroids, emollients, phototherapies, calcineurin inhibitors and immunosuppressants, such as cyclosporine A. Although these therapies reduce inflammation, they also cause serious side effects. Therefore, it is necessary to develop new therapeutic approaches for AD treatment without side effects. There are several studies on natural materials or toxins, such as herbs, ginseng extract and snake venom, for AD treatment. However, treatment of AD with bee venom and its major component, melittin has rarely been studied. EXPERIMENTAL APPROACH Effects of bee venom and melittin were studied in a model of AD in vivo induced by 1-chloro-2,4-dinitrobenzene (DNCB) in female Balb/c mice and in cultures of human keratinocytes, stimulated by TNF-α/IFN-γ. The potential pharmacological effects of bee venom and melittin on these in vivo and in vitro AD-like skin disease models were studied. KEY RESULTS Bee venom and melittin exhibited potent anti-atopic activities, shown by decreased AD-like skin lesions, induced by DNCB in mice. In vitro studies using TNF-α/IFN-γ-stimulated human keratinocytes showed that bee venom and melittin inhibited the increased expression of chemokines, such as CCL17 and CCL22, and pro-inflammatory cytokines, including IL-1β, IL-6 and IFN-γ, through the blockade of the NF-κB and STAT signalling pathways. CONCLUSIONS AND IMPLICATIONS Our results suggest that bee venom and melittin would be suitable for epicutaneous application, as topical administration is often appropriate for the treatment of AD.

Abstract
PURPOSE OF REVIEW Recent studies have highlighted the role of alarmins in asthma pathophysiology and tested the roles of these cytokines in asthmatic patients. This review will discuss the recent advances in the role of alarmins in asthma and the potential of future targeted therapies in asthma. RECENT FINDINGS Epithelial-derived cytokines can be released upon exposure to external stimuli, causing damage to the epithelial barrier and resulting in tissue inflammation. Of these cytokines, IL-25, IL-33 and thymic stromal lymphopoeitin (TSLP), have been associated with asthma. These alarmins are all not only overexpressed in asthmatic airways, particularly in airway epithelial cells, but also in other structural and immune cells. Furthermore, all three alarmins drive type-2 pro-inflammatory responses in several immune cells that have been identified as key players in the pathogenesis of asthma, including innate lymphoid type-2 cells. Clinical trials testing therapeutics that block pathways of the alarmins are in progress. SUMMARY To-date, only TSLP blockade has been reported in human clinical trials, and this approach has shown efficacy in asthmatic patients. Current body of evidence suggests that alarmins are useful upstream targets for treatment of asthma.

Abstract
Emerging evidence demonstrates that the microbiota plays an essential role in shaping the development and function of host immune responses. A variety of environmental stimuli, including foods and commensals, are recognized by the host through the epithelium, acting as a physical barrier. Two allergic diseases, atopic dermatitis and food allergy, are closely linked to the microbiota, because inflammatory responses occur on the epidermal border. The microbiota generates metabolites such as short-chain fatty acids and poly-γ-glutamic acid (γPGA), which can modulate host immune responses. Here, we review how microbial metabolites can regulate allergic immune responses. Furthermore, we focus on the effect of γPGA on allergic T helper (Th) 2 responses and its therapeutic application.

Abstract
Atopic dermatitis is a chronic inflammatory skin disease with a complex
pathogenesis, where changes in skin barrier and imbalance of the immune system
are relevant factors. The skin forms a mechanic and immune barrier, regulating
water loss from the internal to the external environment, and protecting the
individual from external aggressions, such as microorganisms, ultraviolet
radiation and physical trauma. Main components of the skin barrier are located
in the outer layers of the epidermis (such as filaggrin), the proteins that form
the tight junction (TJ) and components of the innate immune system. Recent data
involving skin barrier reveal new information regarding its structure and its
role in the mechanic-immunological defense; atopic dermatitis (AD) is an example
of a disease related to dysfunctions associated with this complex.

Abstract
The cytokine thymic stromal lymphopoietin (TSLP) is involved in the development and the progression of allergic diseases. It is mainly released by epithelial cells at barriers such as skin and gut in response to danger signals. Overexpression of TSLP in keratinocytes (KC) can provoke the development of a type 2 inflammatory response. Additionally, TSLP directly acts on sensory neurons and thereby triggers itch. Since histamine is also increased in lesions of inflammatory skin diseases, the aim of this study was to investigate possible effects of histamine as well as different histamine receptor subtype agonists and antagonists on TSLP production in KC. We therefore stimulated human KC with histamine in the presence or absence of the known TSLP-inductor poly I:C and measured TSLP production at protein as well as mRNA level. Histamine alone did not induce TSLP production in human KC, but pre-incubation with histamine prior to challenge with poly I:C resulted in a significant increase of TSLP production compared to stimulation with poly I:C alone. Experiments with different histamine receptor agonists (H1R: 2-pyridylethylamine; H2R: amthamine; H2R/H4R: 4-methylhistamine (4MH)) revealed a dominant role for the H4R receptor, as 4-MH in combination with poly I:C displayed a significant increase of TSLP secretion, while the other agonists did not show any effect. The increase in TSLP production by 4MH was blocked with the H4R antagonist JNJ7777120. This effect was reproducible also in the murine KC cell line MSC. Taken together, our study indicates a new role for the H4 receptor in the regulation of TSLP in keratinocytes. Therefore, blocking of the H4R receptor in allergic diseases might be promising to alleviate inflammation and pruritus via TSLP.

Biologics and the lung: TSLP and other epithelial cell-derived cytokines in asthma. Pharmacol Ther 2016; 169:104-112. [PMID: 27365223 DOI: 10.1016/j.pharmthera.2016.06.009] [Citation(s) in RCA: 80] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2015] [Accepted: 06/13/2016] [Indexed: 12/21/2022]
Abstract
Asthma is a chronic airway inflammatory disorder with characteristic symptoms of dyspnea, wheeze, chest tightness and cough, and physiological abnormalities of variable airway obstruction, airway hyperresponsiveness, and in some patients with chronic long standing disease reduced lung function. The physiological abnormalities are due to chronic airway inflammation and underlying structural changes to the airway wall. The interaction between the airway epithelium and the environment is crucial to the pathobiology of asthma. Several recent discoveries have highlighted a crucial role of airway epithelial derived cytokines such as interleukin (IL)-25, IL-33 and thymic stromal lymphopoietin (TSLP). These cytokines are collectively known as epithelial "alarmins", which act solely or in concert to activate and potentiate the innate and humoral arms of the immune system in the presence of actual or perceive damage. Understanding the role of alarmins and how they are activated and released may allow the development of novel new therapeutics to treat asthma. This review describes the interactions between inhaled air, the pulmonary microbiome, airway epithelial cell layer and the alarmins, IL-25, IL-33 and TSLP. There is already compelling evidence for a role of TSLP in the airway responses to environmental allergens in allergic asthmatics, as well as in maintaining airway eosinophilic inflammation in these subjects. Further work is required to develop human monoclonal antibodies (hMabs) directed against IL-25 and IL-33 or their receptors, to help understand their role in the initiation and/or persistence of asthma.

Abstract
IL-4 and IL-13 are pleiotropic Th2 cytokines produced by a wide variety of different cell types and responsible for a broad range of biology and functions. Physiologically, Th2 cytokines are known to mediate host defense against parasites but they can also trigger disease if their activities are dysregulated. In this review we discuss the rationale for targeting the IL-4/IL-13 axes in asthma, atopic dermatitis, allergic rhinitis, COPD, cancer, inflammatory bowel disease, autoimmune disease and fibrotic disease as well as evaluating the associated clinical data derived from blocking IL-4, IL-13 or IL-4 and IL-13 together.

Abstract
BACKGROUND Although the therapeutic mechanism of balneotherapy for atopic dermatitis has not been clarified, many atopic patients who visit thermomineral springs have shown clinical improvements. OBJECTIVE This study was aimed to evaluate the immunomodulatory effect of thermomineral water balneotherapy on the atopic dermatitis murine model. METHODS The oxazolone-induced atopic dermatitis murine model was used to evaluate the therapeutic effect of balneotherapy with Deokgu thermomineral water compared with distilled water. Histologic evaluation and confocal microscopic imaging were performed to analyze the lesional expression of cluster-of-differentiation (CD)4 and forkhead box p3 (Foxp3). Lesional mRNA expression of interleukin (IL) 33, thymic stromal lymphopoietin (TSLP), and Foxp3 was evaluated by real-time reverse transcription polymerase chain reaction. RESULTS Compared with the distilled water bath group, confocal microscopic evaluation of CD4 and Foxp3 merged images showed increased expression of regulatory T cells in the thermomineral balneotherapy group. The lesional mRNA level of IL-33 showed a reduced trend in the thermomineral balneotherapy group, whereas the level of mRNA of Foxp3 was increased. TSLP showed a decreased trend in both distilled water and thermomineral water bath groups. There was a trend of reduced expression in lesional IL-33 mRNA but increased cell count of CD4(+) Foxp3(+) regulatory T cells in thermomineral balneotherapy compared with distilled water bath. CONCLUSION Therefore, thermomineral balneotherapy can be an effective and safe adjuvant therapeutic option for atopic dermatitis.

Abstract
Thymic stromal lymphopoietin (TSLP) is an epithelial-derived cytokine similar to IL- 7, whose gene is located on chromosome 5q22.1 and it exerts its biological function through the TSLP-Receptor (TSLP-R). TSLP is expressed primarily by epithelial cells at barrier surfaces such as the skin, gut and lung in response to danger signals. Since it was cloned in 1994, there has been accumulating evidence that TSLP is crucial for the maturation of antigen presenting cells and hematopoietic cells. TSLP genetic variants and its dysregulated expression have been linked to atopic diseases such as atopic dermatitis, asthma, allergic rhinitis and eosinophilic esophagitis.

Abstract
INTRODUCTION The cytokines interleukin (IL)-7 and thymic stromal lymphopoietin (TSLP) signal through the IL-7R subunit and play proinflammatory roles in experimental arthritis and rheumatoid arthritis (RA). We evaluated the effect of inhibition of IL-7R- and TSLPR-signalling as well as simultaneous inhibition of IL-7R- and TSLPR-signalling in murine experimental arthritis. In addition, the effects of IL-7 and TSLP in human RA dendritic cell (DC)/T-cell co-cultures were studied. METHODS Arthritis was induced with proteoglycan in wildtype mice (WT) and in mice deficient for the TSLP receptor subunit (TSLPR-/-). Both mice genotypes were treated with anti-IL-7R or phosphate buffered saline. Arthritis severity was assessed and local and circulating cytokines were measured. Autologous CD1c-positive DCs and CD4 T-cells were isolated from peripheral blood of RA patients and were co-cultured in the presence of IL-7, TSLP or both and proliferation and cytokine production were assessed. RESULTS Arthritis severity and immunopathology were decreased in WT mice treated with anti-IL-7R, in TSLPR-/- mice, and the most robustly in TSLPR-/- mice treated with anti-IL-7R. This was associated with strongly decreased levels of IL-17, IL-6 and CD40L. In human DC/T-cell co-cultures, TSLP and IL-7 additively increased T-cell proliferation and production of Th17-associated cytokines, chemokines and tissue destruction factors. CONCLUSION TSLP and IL-7 have an additive effect on the production of Th17-cytokines in a human in vitro model, and enhance arthritis in mice linked with enhanced inflammation and immunopathology. As both cytokines signal via the IL-7R, these data urge for IL-7R-targeting to prevent the activity of both cytokines in RA.

Abstract
BACKGROUND Thymic stromal lymphopoietin (TSLP) is an extensively studied cytokine linked to the pathogenesis of allergic diseases, but the inherent activities behind TSLP expression are not well defined. OBJECTIVES To explore the conditions favourable to TSLP induction outside of a typically allergic set-up and determine the associated mechanisms, and to assess whether TSLP is similarly controlled in murine and human skin. METHODS A combination of primary keratinocytes, skin explants/epidermal sheets and in vivo strategies was employed. The skin of wild-type and tumour necrosis factor knockout (TNF-/-) mice was subjected to acute irritation. Cells and specimens were stimulated with a range of TSLP inducers in the presence or absence of neutralizing antibodies. TSLP was quantitated by quantitative reverse-transcriptase polymerase chain reaction, enzyme-linked immunosorbent assay and immunohistochemistry. RESULTS In addition to cytokines, skin irritation brought about by various causes (e.g. shaving, scratching and chemical perturbation) elicited uniformly high-level production of TSLP, which entered the circulatory system. Despite the potency of TNF-α as an in vitro TSLP inducer, the use of TNF-/- mice revealed that this mechanism was completely independent of endogenous TNF-α. Conversely, irritation-elicited TSLP depended on interleukin (IL)-1, which had a more pronounced influence in human skin than in murine skin. Murine and human skin differed considerably regarding TSLP regulation. CONCLUSIONS Thymic stromal lymphopoietin is a general responder to disrupted skin homeostasis and may have a role in triggering the alarm system of the skin. TSLP induction is rapid, transient and driven by a mechanism that does not involve TNF-α, but partially relies on the evolutionarily ancient IL-1 system. The irritated skin secretes TSLP into the circulatory system. TSLP regulation varies between species.

Abstract
INTRODUCTION Epithelial cell-derived mediators have emerged as key players for instigating local remodeling and the associated cellular inflammation in asthmatic airways. In particular, the epithelial-derived cytokine, thymic stromal lymphopoietin (TSLP), has been identified as a master switch for allergic inflammation. AREAS COVERED TSLP is expressed by structural and immune cells at the site of allergen entry in the airways. Stimuli for release of TSLP include common triggers of asthma symptoms, and TSLP levels correlate with disease severity. TSLP regulates helper T cell 2 (Th2) humoral immunity through upregulating OX40L on dendritic cells (DCs), which drives Th2 lymphocytes; however, activation of several other cells by TSLP also supports the development of Th2 inflammation. Animal models of asthma demonstrate that increased levels of TSLP can induce many of the characteristics of asthma. EXPERT OPINION The work conducted to date supports a critical role of TSLP in the pathogenesis of allergic asthma. The first clinical trial to block the downstream effects of OX40L has shown reduced levels of circulating IgE and airway eosinophils, confirming the importance of TSLP-induced OX40L levels on DCs. Clinical trials with TSLP blockade are underway and will unequivocally confirm whether TSLP is indeed a key driver of allergic inflammation in asthma.

Abstract
Background Epidemiologic clinical studies suggested that chronic exposure to chlorine products is associated with development of asthma and aggravation of asthmatic symptoms. However, its underlying mechanism was not clearly understood. Studies were undertaken to define the effects and mechanisms of chronic low-dose chlorine exposure in the pathogenesis of airway inflammation and airway hyperresponsiveness (AHR). Methods Six week-old female BALB/c mice were sensitized and challenged with OVA in the presence and absence of chronic low dose chlorine exposure of naturally vaporized gas of 5% sodium hypochlorite solution. Airway inflammation and AHR were evaluated by bronchoalveolar lavage (BAL) cell recovery and non-invasive phlethysmography, respectively. Real-time qPCR, Western blot assay, and ELISA were used to evaluate the mRNA and protein expressions of cytokines and other inflammatory mediators. Human A549 and murine epithelial (A549 and MLE12) and macrophage (AMJ2-C11) cells were used to define the responses to low dose chlorine exposure in vitro. Results Chronic low dose chlorine exposure significantly augmented airway inflammation and AHR in OVA-sensitized and challenged mice. The expression of Th2 cytokines IL-4 and IL-5 and proinflammatory cytokine IL-1β and IL-33 were significantly increased in OVA/Cl group compared with OVA group. The chlorine exposure also activates the major molecules associated with inflammasome pathway in the macrophages with increased expression of epithelial alarmins IL-33 and TSLP in vitro. Conclusion Chronic low dose exposure of chlorine aggravates allergic Th2 inflammation and AHR potentially through activation of inflammasome danger signaling pathways.

Abstract
BACKGROUND Eosinophilic esophagitis (EoE) is an atopic disease characterized by eosinophilic inflammation in which dietary antigens (in particular, milk) play a major role. EoE is most likely a mixed IgE and non-IgE food-mediated reaction in which overexpression of Th2 cytokines, particularly IL-13, play a major role; however, the cells responsible for IL-13 overexpression remain elusive. Th2-cytokines are secreted following the ligation of invariant natural killer T cell receptors to sphingolipids (SLs). Sphingolipids (SLs) are presented via the CD1d molecule on the INKTs surface. Cow's milk-derived SL has been shown to activate iNKTs from children with IgE-mediated food allergies to milk (FA-MA) to produce Th2 cytokines. The role of iNKTs and milk-SL in EoE pathogenesis is currently unknown. OBJECTIVE The aim of this study was to investigate the role of iNKTs and milk-SL in EoE. METHODS Peripheral blood mononuclear cells (PBMCs) from 10 children with active EoE (EoE-A), 10 children with controlled EoE (EoE-C) and 16 healthy controls (non-EoE) were measured ex vivo and then incubated with α-galactosylceramide (αGal) and milk-SL. INKTs from peripheral blood (PB) and oesophageal biopsies were studied. RESULTS EoE-A children had significantly fewer peripheral blood iNKTs with a greater Th2-response to αGal and milk-SM compared with iNKTs of EoE-C and non-EoE children. Additionally, EoE-A children had increased iNKT levels in oesophageal biopsies compared with EoE-C children. CONCLUSION Milk-SLs are able to activate peripheral blood iNKTs in EoE-A children to produce Th2 cytokines. Additionally, iNKT levels are higher at the site of active oesophageal eosinophilic inflammation. CLINICAL RELEVANCE This study suggests that sphingolipids (SLs) contained in milk may drive the development of EoE by promoting an iNKT-cell-mediated Th2-type cytokine response that facilitates eosinophil-mediated allergic inflammation.

Abstract
Background Vitiligo and atopic dermatitis (AD) are common dermatological disorders which may cause significant psychological and social distress leading to impaired quality of life (QoL) in patients. Objective We evaluated the degree of psychological stress and impairment of QoL in vitiligo patients as compared with AD patients and normal controls (NCs). Methods A total of 60 patients from each group and 60 NCs were enrolled. Five questionnaires on depression (Beck depression inventory, BDI), state anxiety (SA) and trait anxiety (TA), interaction anxiousness (IAS), private body consciousness (PBC) and dermatologic QoL were used. Results The vitiligo patients had a significantly higher level of TA (p<0.01), PBC (p<0.001) and impaired QoL (p<0.001) than NCs, but not BDI, SA and IAS. The AD patients had significantly higher scores for all five questionnaire items compared with NCs. In the comparison between the AD and vitiligo groups, all of the indexes except body consciousness were higher in AD patients than in vitiligo patients: BDI (p<0.01), SA (p<0.05), TA (p<0.001), IAS (p<0.01) and impaired QoL (p<0.001). Exposure of vitiligo lesions was not a significant variable in the analysis of the contribution of clinical variables of vitiligo on psychological stress and QoL. Conclusion Vitiligo, which is not accompanied by any symptoms, involves less psychological impact than AD, which is accompanied by itching. Compared to NCs, however, the elevated general anxiety and body consciousness in patients with vitiligo suggests that they may be more concerned with the aggravation of hypopigmented patches than difficulties in social interactions.

Abstract
BACKGROUND Innate immune sensors control key cytokines that regulate T-cell priming and T-cell fate. This is particularly evident in allergic reactions, which represent ideal systems to study the interplay of innate and adaptive immunity. In patients with contact dermatitis, inflammasome-mediated IL-1 activation is responsible for a TH1 immune response. Surprisingly, the IL-1 signaling pathway was also proposed to control the activation of thymic stromal lymphopoietin (TSLP), a cytokine implicated in development of the T(H)2 response in patients with atopic dermatitis (AD) and asthma. OBJECTIVES We sought to assess the effect of the inflammasome on TSLP expression levels and the development of AD. METHODS We studied the effect of the inflammasome activator 2,4-dinitrofluorobenzene, and IL-1β on TSLP mRNA expression levels in mouse and human cell lines (in vitro assays), as well as in live mice and on human skin transplants. We also assessed the effect of 2,4-dinitrofluorobenzene on TSLP and the TH2 response in mice in which the inflammasome and IL-1 signaling pathways were blocked, either genetically or pharmacologically, in 2 models of AD. RESULTS We provide in vitro and in vivo evidence that inflammasome activation has an inhibitory role on TSLP mRNA expression and T(H)2 cell fate in the skin. We also show that solvents influence the activation of TSLP and IL-1β and direct the T-cell fate to a given hapten. CONCLUSION Our observations strongly suggest that the TH1 versus TH2 cell fate decision is regulated at multiple levels and starts with innate immune events occurring within peripheral epithelial tissues.

Abstract
BACKGROUND Systemic lupus erythematosus (SLE) is associated with a numerical and functional reduction of peripheral blood (PB) invariant natural killer T (iNKT) cells. Limited information exists on the role of iNKT cells in the pathogenesis of lupus erythematosus. OBJECTIVE To investigate the frequency and phenotype of iNKT cells in PB and dermal infiltrates from patients with SLE, subacute-cutaneous lupus erythematosus (SCLE) and discoid lupus erythematosus (DLE). METHODS PB was obtained from 23 SLE, 6 SCLE, and 11 DLE patients, and from 30 healthy controls. iNKT cell frequency and CCR4/CCR6 surface expression were assessed by flow cytometry. The frequency and phenotype of skin infiltrating Vα24(+)Vβ11(+) iNKT cells were investigated by immunofluorescence in lesional biopsies from 20 patients, unaffected skin from 3 patients, and from 6 healthy controls. RESULTS Lupus erythematosus patients displayed significantly lower percentages of circulating CD3(+)6B11(+) iNKT cells compared to healthy controls. Whereas CCR6 expression on iNKT cells was enhanced in active SLE patients regardless of cutaneous involvement compared to healthy controls, CCR4 was exclusively increased in patients with active cutaneous lesions. Furthermore, iNKT cells were significantly enriched in lesional skin of SLE and DLE patients, but not in unaffected skin of lupus patients. The majority of lesional iNKT cells expressed IFN-γ and CCR4. CONCLUSION The deficiency in circulating iNKT cells in cutaneous lupus erythematosus is associated with an increase of iNKT cells at the site of cutaneous inflammation. These data underscore the importance of analyzing iNKT cells not only in PB, but also in the target tissues.

Abstract
Atopic dermatitis (AD) is a highly pruritic, chronic relapsing inflammatory skin disease characterized by innate and adaptive immune reactions. In AD, innate immune mechanisms such as pattern recognition receptors and antimicrobial peptides have been investigated in detail, but recently, epidermis-derived cytokines, namely thymic stromal lymphopoietin (TSLP), IL-25 and IL-33, were shown to participate in innate immune reactions independently of adaptive immunity. In addition to conventional innate cells, such as mast cells, basophils and eosinophils, Th2 cytokine-producing invariant natural killer T (iNKT) cells, innate lymphoid cells (ILCs) and Th17/Th22 cytokine-producing innate cells - iNKT cells and natural killer (NK)-like cells - can participate in innate immune modulation in AD. Accordingly, early control of innate immune responses in AD before activation of adaptive immune responses by conventional T and B cells that perpetuate chronic skin inflammation may adequately alleviate acute exacerbations of AD. Therefore, we hypothesized that select immune modulators targeting the innate immune response could potentially be used for individualized treatment of AD.

Abstract
Thymic stromal lymphopoietin (TSLP), an interleukin 7-like cytokine, can trigger dendritic cell (DC)-mediated T-helper type 2 (Th2) inflammatory responses. Recent evidence demonstrates that cytokines TSLP and OX40 (CD134)/OX40 ligand seem to be important players in the maintenance of Th2 memory pool in the pathogenesis of asthma. Accumulating data reveal that the pathogenic T cells involved in asthma are likely to be inflammatory Th2 cells. TSLP is involved in the development of asthma through crosstalk with nuclear factor NF-ĸB. Progression of skin fibrosis in atopic dermatitis occurs via TSLP/TSLP receptor. TSLP-mediated dermal inflammation aggravates experimental allergic asthma. Also, TSLP polymorphisms are associated with susceptibility to asthma, atopic dermatitis, and eczema herpeticum. These findings suggest a master switch of TSLP in the initiation of allergic and adaptive inflammation through innate pathways at the epithelial cell-DC interface. The TSLP pathway is therefore a promising target for immunotherapy of allergic diseases.

Abstract
Asthma is an inflammatory disorder of the airways, characterized by infiltration of mast cells, eosinophils, and Th2-type CD4+ T cells in the airway wall. Airway epithelium constitutes the first line of interaction with our atmospheric environment. The protective barrier function of the airway epithelium is likely impaired in asthma. Furthermore, recent studies suggest critical immunogenic and immunomodulatory functions of airway epithelium. In particular, a triad of cytokines, including IL-25, IL-33 and TSLP, is produced and released by airway epithelial cells in response to various environmental and microbial stimuli or by cellular damage. These cytokines induce and promote Th2-type airway inflammation and cause remodeling and pathological changes in the airway walls, suggesting their pivotal roles in the pathophysiology of asthma. Thus, the airway epithelium can no longer be regarded as a mere structural barrier, but must be considered an active player in the pathogenesis of asthma and other allergic disorders.

Abstract
Thymic stromal lymphopoietin (TSLP) exerts a marked influence on the polarization of dendritic cells to drive T helper (Th) 2 cytokine production, and has been linked to allergic airway diseases. Although TSLP is produced by airway epithelium, TSLP production in laryngeal arytenoid fibroblasts remains largely unexplored. We examined the effect of Toll-like receptor (TLR) ligands and the cross-talk that occurs among different TLR ligands on TSLP production in arytenoid fibroblasts. Since mRNA of TLR 2, 3, 4, and 9 has been found to be expressed in arytenoid fibroblasts, we examined the effect on its production of TLR ligands. TSLP production by arytenoid fibroblasts was strongly induced in the presence of polyinosinic-polycytidylic acid (poly(I:C)), a ligand of TLR3. Its production was synergistically induced in the presence of IL-4, to a level more than 100 times higher than that observed in the absence of poly(I:C) or IL-4. We also revealed that B type DNA containing CpG motifs (CpG-DNA) coding for a TLR9 ligand markedly suppressed both poly(I:C)-induced and poly(I:C)-plus-IL-4-induced TSLP production. B type CpG-DNA decreased the poly(I:C)-induced phosphorylation of c-Jun N-terminal kinase (JNK), and pre-incubation with SP600125 (inhibitor of JNK) reduced the poly(I:C)-induced TSLP-production. These results indicate that human arytenoid fibroblasts strongly induce TSLP production with stimulation by double-stranded RNA (dsRNA), which can be inhibited by CpG-DNA and participate in immune allergic responses.

Abstract
Epithelial cells respond to physicochemical damage with up-regulation of major histocompatibility complex-like ligands that can activate the cytolytic potential of neighboring intraepithelial T cells by binding the activating receptor, NKG2D. The systemic implications of this lymphoid stress-surveillance response, however, are unknown. We found that antigens encountered at the same time as cutaneous epithelial stress induced strong primary and secondary systemic, T helper 2 (T(H)2)-associated atopic responses in mice. These responses required NKG2D-dependent communication between dysregulated epithelial cells and tissue-associated lymphoid cells. These data are germane to uncertainty over the afferent induction of T(H)2 responses and provide a molecular framework for considering atopy as an important component of the response to tissue damage and carcinogenesis.

Abstract
Atopic dermatitis (AD) results from barrier defects combined with modified immune responses of the innate and the adaptive immune system to exogenous and endogenous factors. Recent research has continued to sort out the complex pathophysiologic puzzle of this frequent skin disease. However, the network of mechanisms leading to the manifestation of AD is far from being completely understood.

Abstract
Thymic stromal lymphopoietin (TSLP) plays a critical role in allergic diseases such as atopic dermatitis, asthma, and chronic obstructive pulmonary disease. Naringenin has various effects such as anti-atherogenic, anti-oxidant, and anti-inflammatory effects. However, the effect of naringenin on the production of TSLP has not been clarified. Thus, we investigated how naringenin inhibits the production of TSLP in the human mast cell line (HMC-1) cells. Naringenin inhibited the production and mRNA expression of TSLP in HMC-1 cells. The maximal inhibition rate of TSLP production by naringenin (100 μM) was 62.27 ± 10.79%. Naringenin also inhibited the nuclear factor-κB luciferase activity induced by phorbol myristate acetate plus A23187. In the activated HMC-1 cells, the activations of receptor-interacting protein (RIP)2 and caspase-1 were increased, whereas the activations of RIP2 and caspase-1 were decreased by pretreatment with naringenin. These results suggest that naringenin can be used to treat inflammatory and atopic diseases through the inhibition of TSLP.

Abstract
Thymic stromal lymphopoietin (TSLP) plays a pivotal role in allergic diseases such as atopic dermatitis, asthma, and chronic obstructive pulmonary disease. However, it has not been clarified the effect of berberine (BER) on the production of TSLP yet. Thus, we investigated how BER inhibits the production of TSLP in the human mast cell line (HMC-1) cells. We used enzyme-linked immunosorbent assay, reverse transcription-polymerase chain reaction, luciferase assay, and Western blot analysis to investigate the effects of BER. BER inhibited the production and mRNA expression of TSLP in HMC-1 cells. BER also inhibited the nuclear factor-κB luciferase activity induced by phorbol myristate acetate plus A23187. BER inhibited the activation of caspase-1 in HMC-1 cells. Furthermore, BER inhibited the production of TSLP in primary mast cells. These results provide evidence that BER can help to treat inflammatory and atopic diseases through the inhibition of TSLP.
