Abstract
Psoriasis is one of the most common inflammatory diseases, characterized by scaly erythematous plaques on the skin. The accumulated evidence on immunopathology of psoriasis suggests that inflammatory reaction is primarily mediated by T helper (Th) cells. The differentiation of Th cells plays important roles in psoriatic progression and it is regulated by transcription factors such as T-bet, GATA3, RORγt, and FOXP3, which can convert naïve CD4+ T cells, respectively, into Th1, Th2, Th17 and Treg subsets. Through the activation of the JAK/STAT and Notch signaling pathways, together with their downstream effector molecules including TNF-α, IFN-γ, IL-17, TGF-β, these subsets of Th cells are then deeply involved in the pathogenesis of psoriasis. As a result, keratinocytes are abnormally proliferated and abundant inflammatory immune cells are infiltrated in psoriatic lesions. We hypothesize that modulation of the expression of transcription factors for each Th subset could be a new therapeutic target for psoriasis. In this review, we will focus on the recent literature concerning the transcriptional regulation of Th cells in psoriasis.

Chin Med 2020; 15:53. [PMID: 32489402 PMCID: PMC7247251 DOI: 10.1186/s13020-020-00334-w] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2020] [Accepted: 05/14/2020] [Indexed: 02/06/2023] Open
Abstract
Background Asthma, a common respiratory disease, is harmful biological effect to our health. As a traditional Chinese medicine for asthma, Majie cataplasm could alleviate the symptoms of asthma and its compositions have immunomodulatory effects. Previous experiments showed that Majie cataplasm was an effective approach to mitigate asthma airway remodeling and had the potential to regulate Th2 cytokines of IL-5 and IL-13. Therefore, our further research focuses on the explanation about the regulatory effect of Majie cataplasm on reshaping Th1/Th2 through their related transcription factors. Methods In this experiment, the launch of asthma model was made by inducing with Ovalbumin (OVA) in C57 mice (n = 40), including 4 groups: the untreated control group (n = 10), the asthma model group (n = 10), the dexamethasone group (n = 10) and the Majie cataplasm group (n = 10). After the intervention, all groups of animals got detected for serum IgE levels, and HE staining of lung tissues was to observe and examine pathological changes. Meanwhile, we analyzed the secretion of IL-4+ T cells and IFN-γ+ T cells in spleen by flow cytometry. The expressions of transcription factor STAT6 mRNA, GATA-3 mRNA and T-bet mRNA in lung tissues was tested by PCR, and western blot had been used to detect levels of JAK2 and STAT3. Results We found that Majie cataplasm eased the content of serum IgE and lung inflammation. It could lower the increased number of IL-4+ T cells and IFN-γ+ T cells (P < 0.0001, P < 0.01) in asthmatic mice and curb the expression of STAT6 mRNA and GATA-3 (P < 0.0001, P < 0.01) mRNA as well as the protein levels of JAK2 (P < 0.001) and the ratio of pSTAT3/STAT3 (P < 0.05). Besides, Majie cataplasm made its mark on T-bet mRNA by improving it (P < 0.0001). Conclusion These data suggest that Majie cataplasm exert an anti-inflammatory effect of Th2 by rebalancing Th1/Th2 through corresponding transcription factor STAT6, GATA-3, STAT3, and T-bet, which providing a strong cornerstone for asthma control.

Abstract
BACKGROUND/AIMS Thymic stromal lymphopoietin (TSLP) is an epithelial cell-derived cytokine that plays a key role in Th2-mediated inflammation, both directly by promoting the proliferation of naïve CD4 Th2 cells, and indirectly by activating dendritic cells (DCs). TSLP-activated DCs induce the expansion of chemoattractant receptor homologous molecule expressed on Th2 (CRTH2)+ CD4+ Th2 memory cells, which undergo a Th2 response and express prostaglandin D2 (PGD2) synthase. CRTH2, a PGD2 receptor, is a selective Th2-cell surface marker. We investigated the effects of an anti-TSLP antibody (Ab) and a CRTH2 antagonist, as well as their mechanisms of action, in a mouse model of acute asthma. METHODS BALB/c mice were sensitized and challenged with ovalbumin. We then evaluated the effects of the administration of an anti-TSLP Ab either alone or together with a CRTH2 antagonist on cell counts, Th2 cytokine levels in bronchoalveolar fluid, and the levels of epithelium-derived cytokines such as TSLP, interleukin (IL) 33, and IL-25 in lung homogenates, as well as airway hyper-responsiveness (AHR). RESULTS Anti-TSLP Ab and the CRTH2 antagonist significantly attenuated eosinophilic airway inflammation, AHR, and the expression of Th2 cytokines. The expression of GATA-3 and the levels of IL-33 and IL-25 in lung tissues were affected by the combined anti-TSLP and CRTH2 antagonist treatment. CONCLUSION These results suggest that the dual blockade of TSLP and CRTH2 may serve as an effective treatment target for eosinophilic asthma.

Abstract
Several studies have shown a strong association between atopic diseases and autism spectrum disorder (ASD). However, the risk of atopic diseases in individuals having ASD-affected siblings has never been investigated. This nationwide population-based cohort study included 2762 individuals with ASD-affected siblings and 11,048 controls. Diagnoses of atopic diseases, including asthma, atopic dermatitis, allergic rhinitis, and allergic conjunctivitis, were ascertained from 1996 or the birth data to the end of 2011. Individuals with ASD-affected siblings had a higher risk for asthma, atopic dermatitis, allergic rhinitis, allergic conjunctivitis, and multiple atopic diseases compared with controls. In conclusion, individuals with ASD-affected siblings were more likely than were the controls to develop atopic diseases, suggesting shared familial mechanisms underlying the two conditions.

Abstract
Knowledge of genetic origins of obstructive lung diseases has made inhaled gene therapy an attractive alternative to the current standards of care that are limited to managing disease symptoms. Initial lung gene therapy clinical trials occurred in the early 1990s following the discovery of the genetic defect responsible for cystic fibrosis (CF), a monogenic disorder. However, despite over two decades of intensive effort, gene therapy has yet to help patients with CF or any other obstructive lung disease. The slow progress is due in part to poor understanding of the biological barriers to inhaled gene therapy. Encouragingly, clinical trials have shown that inhaled gene therapy with various viral vectors and non-viral gene vectors is well tolerated by patients, and continued research has provided valuable lessons and resources that may lead to future success of this therapeutic strategy. In this review, we first introduce representative obstructive lung diseases and examine limitations of currently available therapeutic options. We then review key components for successful execution of inhaled gene therapy, including gene delivery systems, primary physiological barriers and strategies to overcome them, and advances in preclinical disease models with which the most promising systems may be identified for human clinical trials.

Abstract
BACKGROUND Atopic dermatitis (AD) is an allergic disorder caused by both immunological dysregulation and epidermal barrier defect. Several studies have investigated the association between AD and mental health disorders. Autism spectrum disorders (ASD) are a heterogeneous group of neurodevelopmental conditions characterized by impairments in social communication and restricted, stereotyped interests and behaviors. The concurrent increased prevalence of AD and ASD in the last decades has led many scientists to investigate the relationship between the two diseases. OBJECTIVE The aim of this systematic review was to examine the association between AD and ASD. METHODS A systematic review was performed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. PubMed and ScienceDirect were searched up to March 2015 for all reports examining the association between ASD and AD. Descriptive statistics of the studies are reported. RESULTS The review included 18 studies assessing the association between ASD and AD. Of these studies, two focused on ASD in relation to AD alone, 14 discussed ASD in relation to both AD and other atopic disorders, and two evaluated AD in parents of children with ASD. Most of these studies found a positive association between the two disorders, although there were some studies going in the opposite direction. The entity of the association is somewhat inconsistent among the different studies given that the frequencies of AD in ASD compared with a control group ranged from 7 to 64.2%. In addition, odds ratios (ORs) or hazard ratios (HRs) gave different results as three studies found a weak association with an OR below 2 and a nonsignificant p value, and three other studies found a moderate or strong association with an OR ranging from 1.52 to 7.17 and a significant p value. When all atopic disorders were considered when evaluating the risk of ASD, the association was strong with an HR of 3.4 or an OR of 1.24 and p < 0.001. CONCLUSIONS Overall, the results of this systematic review seem to reveal an association between ASD and AD, suggesting that subjects with ASD have an increased risk of presenting with AD compared with typically developing controls, and vice versa. This association is supported by clinical/epidemiological aspects, shared genetic background and common immunological and autoimmune processes. However, the variability in study population and design, and the presence of other risk factors acting as confounding factors, sometimes contribute to inconsistent results. Further studies are needed to clarify the underlying pathophysiologic mechanism explaining the association between ASD and AD and to explore the causal association between the two conditions.

Abstract
Allergic disease represents a significant global health burden, and disease incidence continues to rise in urban areas of the world. As such, a better understanding of the basic immune mechanisms underlying disease pathology are key to developing therapeutic interventions to both prevent disease onset as well as to ameliorate disease morbidity in those individuals already suffering from a disorder linked to type-2 inflammation. Two factors central to type-2 immunity are interleukin (IL)-4 and IL-13, which have been linked to virtually all major hallmarks associated with type-2 inflammation. Therefore, IL-4 and IL-13 and their regulatory pathways represent ideal targets to suppress disease. Despite sharing many common regulatory pathways and receptors, these cytokines perform very distinct functions during a type-2 immune response. This review summarizes the literature surrounding the function and expression of IL-4 and IL-13 in CD4+ T cells and innate immune cells. It highlights recent findings in vivo regarding the differential expression and non-canonical regulation of IL-4 and IL-13 in various immune cells, which likely play important and underappreciated roles in type-2 immunity.

Abstract
Airway inflammation in allergic asthma reflects a threshold response of the innate immune system, including group 2 innate lymphoid cells (ILC2), followed by an adaptive Th2 cell-mediated response. Transcription factor Gata3 is essential for differentiation of both Th2 cells and ILC2. We investigated the effects of enforced Gata3 expression in T cells and ILC2 on the susceptibility of mice to allergic airway inflammation (AAI). We used CD2-Gata3 transgenic (Tg) mice with enforced Gata3 expression driven by the CD2 promoter, which is active both in T cells and during ILC2 development. CD2-Gata3 Tg mice and wild-type (WT) littermates were analyzed in mild models of AAI without adjuvants. Whereas OVA allergen exposure did not induce inflammation in WT controls, CD2-Gata3 Tg mice showed clear AAI and enhanced levels of IL-5 and IL-13 in bronchoalveolar lavage. Likewise, in house dust mite-driven asthma, CD2-Gata3 Tg mice were significantly more susceptible to AAI than WT littermates, whereby both ILC2 and Th2 cells were important cellular sources of IL-5 and IL-13 in bronchoalveolar lavage and lung tissue. Compared with WT littermates, CD2-Gata3 Tg mice contained increased numbers of ILC2, which expressed high levels of IL-33R and contributed significantly to early production of IL-4, IL-5, and IL-13. CD2-Gata3 Tg mice also had a unique population of IL-33-responsive non-B/non-T lymphoid cells expressing IFN-γ. Enforced Gata3 expression is therefore sufficient to enhance Th2 and ILC2 activity, and leads to increased susceptibility to AAI after mild exposure to inhaled harmless Ags that otherwise induce Ag tolerance.

Abstract
Airway hyperreactivity and inflammation are important factors in the aggravation of lung function. Suplatast tosilate (IPD) is a novel and unique anti‑asthma clinical compound. However, the mechanisms of IPD action in the inhibition of asthma remain to be elucidated. The present study aimed to investigate the role of the GATA binding protein 3 (GATA‑3)/interleukin (IL)‑5 signaling pathway in IPD‑induced inhibition of asthma. Sprague‑Dawley rats were sensitized by intraperitoneal injection with ovalbumin (OVA) to establish an animal model of asthma. IPD was administered continuously (C‑IPD) or at a later stage (L‑IPD). Budesonide (BUD) was used as a positive control. Airway resistance and the expression of genes at the mRNA and protein levels were measured. Morphological changes in lung tissue and the percentage of eosinophils (EOS) in peripheral blood were observed and correlation analysis was performed. The results revealed that sensitization by OVA significantly increased airway resistance and the percentage of EOS in peripheral blood and induced significant inflammatory changes in lung tissue, as demonstrated by thick epithelium, goblet cell hyperplasia and submucosal cell infiltration. In addition, sensitization by OVA was found to markedly upregulate IL‑5 mRNA and protein expression. Airway resistance was found to positively correlate with the expression of IL‑5 in the rat lung tissues. Sensitization by OVA was also observed to markedly enhance GATA‑3 protein expression and GATA‑3 levels were found to positively correlate with airway resistance and IL‑5 levels. Similar to the effect of BUD, treatment with C‑IPD or L‑IPD was found to significantly attenuate OVA‑induced increases in airway resistance and the percentage of EOS in peripheral blood. Notably, treatment with C‑IPD or L‑IPD markedly reduced the OVA-induced expression of IL‑5 and GATA‑3. In the present study, IPD intervention was demonstrated to ameliorate airway hyperreactivity and inflammation and the mechanisms may involve inhibition of the GATA‑3/IL‑5 signaling pathway.

Abstract
TH17 cells, which require the expression of both retinoic acid receptor-related orphan receptors α and γt (RORαand RORγt) for full differentiation and function, have been implicated as major effectors in the pathogenesis of inflammatory and autoimmune diseases. We recently demonstrated that the Liver X Receptor (LXR) agonist, T0901317 (T09), also displays high-affinity RORα and RORγ inverse activity, potentially explaining its effectiveness in various TH17-mediated autoimmune disease models. However, recent studies suggest that in conjunction with the RORs, LXR mediates a negative regulatory effect on TH17 cell differentiation. Since T09 acts on both LXRs and RORs, it presents as a valuable tool to understand how compounds with mixed pharmacology affect potential pathological cell types. Therefore, using T09, we investigated the mechanism by which the LXRs and RORs affect TH17 cell differentiation and function. Here we demonstrate that T09 activity at RORα and γ, not LXR, is facilitating the inhibition of TH17 cell differentiation and function. We also demonstrate that LXR activity inhibits the differentiation and function of TH1, TH2 and iTreg cells. Finally, T09 inhibited T cell proliferation and induced cell death. These data help explain much of the efficacy of T09 in inflammatory models and suggest that the generation of synthetic ligands with graded, combined LXR and ROR activity may hold utility in the treatment of inflammatory and autoimmune diseases where targeting both TH17 and TH1 cells is required.

Abstract
T helper cells that produce Interleukin-17 (IL-17) (TH17 cells) are a recently identified CD4+ T-cell subset with characterized pathological roles in autoimmune diseases1–3. The nuclear receptors retinoic acid receptor-related orphan receptors α and γt (RORα and RORγt) have indispensible roles in the development of this cell type4–7. Here we present a first-in-class, high-affinity synthetic ligand, SR1001, specific to both RORα and RORγt that inhibits TH17 cell differentiation and function. SR1001 binds specifically to the ligand binding domains (LBDs) of RORα and RORγt inducing a conformational change within the LBD that encompasses repositioning of helix 12 leading to diminished affinity for coactivators and increased affinity for corepressors resulting in suppression of the receptors transcriptional activity. SR1001 inhibited the development of murine TH17 cells as demonstrated by inhibition of IL-17A gene expression and protein production. Additionally, SR1001 inhibited the expression of cytokines when added to differentiated murine or human TH17 cells. Finally, SR1001 effectively suppressed the clinical severity of autoimmune disease in mice. Thus, our data demonstrates the feasibility of targeting the orphan receptors RORα and RORγt to specifically inhibit TH17 cell differentiation and function and indicates that this novel class of compound has potential utility in the treatment of autoimmune diseases.

Abstract
Interleukin-10 was originally described as a factor that inhibits cytokine production by murine Th1 clones. Recent studies have since shown that IL-10 can also downregulate Th2 clones and their production of IL-4 and IL-5. Because of its immuno-suppressive properties, IL-10 has been suggested as a potential therapy for allergic inflammation and asthma. However, the pathophysiological role of IL-10 in vivo has not been clearly elucidated. We investigated the effects of IL-10 administration on the production of IgE, cytokine and allergen-induced Th2 cytokine production as well as its effects on eosinophilic inflammation. We established GATA-3/TCR double transgenic (GATA-3/TCR-Tg) mice by crossing GATA-3 transgenic mice with ovalbumin (OVA)-specific TCR transgenic mice; these mice were then sensitized using an intraperitoneal injection of OVA adsorbed to alum and challenged with the intratracheal instillation of an allergen. When GATA-3/TCR-Tg mice sensitized with OVA and alum were injected with C57-IL-10 cells before OVA inhalation, the levels of IL-5, IL-13, and IL-4 decreased by 40-85% and number of eosinophils decreased by 70% (P<0.03) in the murine bronchoalveolar lavage fluid (BALF). These results suggest that IL-10 plays an important role downstream of the inflammatory cascade in the Th2 response to antigens and in the development of BALF eosinophilia and cytokine production in a murine model of asthma. These immunosuppressive properties in animal models indicate that IL-10 could be a potential clinical therapy for the treatment of allergic inflammation.

Abstract
The pathophysiological characteristics of bronchial asthma consist of chronic inflammation of airways, airway hyperresponsiveness, and bronchoconstriction. Studies have shown that T helper type 2 (Th2) cytokines produced by both T cells and mast cells in the airway contribute substantially to the initiation of inflammation in both experimental and human bronchial asthma. GATA-3 is a transcription factor essential to the production of Th2 cytokines by T lymphocytes. To clarify the role of GATA-3-expressing T cells in the pathophysiology of bronchial asthma, we utilized transgenic (Tg) mice carrying the GATA-3 gene and the ovalbumin (OVA)-specific T cell receptor gene (GATA-3-Tg/OVA-Tg). Mice were intranasally administrated OVA without systemic immunization. Airway responses were analyzed with noninvasive and invasive whole body plethysmographs. GATA-3-Tg/OVA-Tg mice exhibited significantly higher IL-13 and IL-4 protein expression in the airway. Although there were no differences in the types of infiltrating cells between GATA-3-Tg/OVA-Tg and GATA-3-non-Tg/OVA-Tg mice and no significant increase in IgE level in either group compared with nontreated mice, the response after ACh inhalation was significantly elevated in GATA-3-Tg/OVA-Tg on the seventh day of intranasal treatment with OVA. This hyperresponsiveness was inhibited by 5-lipoxygenase inhibitor and IL-13 neutralization, suggesting that airway responses were induced through IL-13 and leukotriene pathway. In conclusion, airway hyperresponsiveness, a characteristic of bronchial asthma, is regulated at the level of GATA-3 transcription by T lymphocytes in vivo.

Abstract
GATA-3 appears to be key to the Th2 response. However, few in vivo experiments have examined the function of GATA-3 in Th1 and Th2 immune responses. We developed two lines of GATA-3-transgenic (Tg) mice harboring the SRalpha or lck promoters and examined the Th2 immune responses of mice infected with the intestinal nematode Nippostrongylus brasiliensis and the Th1 responses with purified derivative of tuberculin (PPD) immunization. Numbers of peripheral blood eosinophils in all GATA-3-Tg mice increased 10- to 20-fold after primary infection with N. brasiliensis and 25-100-fold after secondary infection. The number of eosinophils in infected GATA-3-Tg mice was significantly higher than that in infected control littermates. Total IgE levels after primary infection in GATA-3-Tg mice were 8-450-fold increased, which was significantly higher than those of control mice. Mesenteric lymph node cells of infected GATA-3-Tg mice upon stimulation with N. brasiliensis antigen secreted more IL-5 and IL-13 than those of control mice. However, production of IL-4 and IFN-gamma were comparable between GATA-3-Tg and controls. Mice immunized with PPD were intradermally challenged with PPD to induce delayed type hypersensitivity (DTH). The amount of footpad swelling caused by the DTH reaction in GATA-3-Tg mice was significantly smaller than that of control littermates. Inguinal lymph node cells from GATA-3-Tg mice stimulated with PPD in vitro secreted more IL-5, IL-10 and less IFN-gamma than those of control littermates. These results suggested that Th1 and Th2 driven conditions enhance IL-5 production in GATA-3-Tg mice through the direct binding of GATA-3 to the IL-5 promoter region. The influence of GATA-3 on IL-13, IFN-gamma and IL-10 production varied according to the stimulating conditions. However, IL-4 production was not significantly elevated in GATA-3-Tg mice, indicating that IL-4 and IL-5 production was differentially regulated in these mice.
