Atopic dermatitis (AD) is a chronic relapsing disease with complex pathogenesis. Among them, inflammation is one of the primary pathogenesis of AD. AD is characterized by infiltration of lymphocytes into the skin’s dermis, and the skin homing of lymphocytes plays an essential role in the recurrence of AD. Currently, there is more and more evidence to support this view. This article reviews the relevant role of T lymphocyte skin-homing-related molecules in the recurrence of AD to provide a reference for the cure of AD.
Primary cilia (PC) are essential signaling hubs for proper epithelial formation and the maintenance of skin homeostasis. Found on most cells in the human body, including skin cells, PC facilitate signal transduction that allows ciliated cells to interact with the immune system via multiple pathways, helping to maintain immune system homeostasis. PC can be altered by various microenvironmental stimuli to develop corresponding regulatory functions. Both PC and ciliary signaling pathways have been shown to be involved in the immune processes of various skin lesions. However, the mechanisms by which PC regulate cellular functions and maintain immune homeostasis in tissues are highly complex, and our understanding of them in the skin remains limited. In this paper, we discuss key ciliary signaling pathways and ciliated cells in the skin, with a focus on their immunomodulatory functions. We have compiled evidence from various cells, tissues and disease models to help explore the potential immunomodulatory effects of PC in the skin and their molecular mechanisms.
Ethnopharmacological relevance: Mahuang-Lianqiao-Chixiaodou decoction (MLCD) is a traditional Chinese medicinal (TCM) formula recorded in the Treatise on Febrile Diseases. It is commonly used for clinical treatment of atopic dermatitis (AD). However, the potential mechanisms of MLCD intervention in AD combined with mental disorders behaviors such as anxiety and depression remain elusive and deserves further investigation.Aim of the study: The study aims to observe the effect of MLCD on anxiety-and depression-like behaviors in AD mice and explore the possible neuroinflammatory mechanism of NOD-like receptor 3 (NLRP3) inflammasome.Materials and methods: The chemical components of MLCD extracts were identified using UHPLC-MS. The AD mice were induced by 2,4-dinitrofluorobenzene and treated with MLCD or mometasone furoate (MF, as a positive control) for 7 days. The pathological changes in their skin tissue and brain hippocampus were observed by hematoxylin-eosin staining. Elevated plus-maze test (EPM), open field test (OFT), and the suspended tail (TST) were used to measure the anxiety-and depressive-like behaviors in AD mice. Expression of NLRP3 inflammasome-related proteins in brain hippocampus were measured by the quantitative real-time polymerase chain reaction (qPCR) and western blotting (WB).Results: We found that MLCD contain many active ingredients, including ephedrine, Forsythoside A, phillyrin, glycyrrhizic acid, etc. Both MLCD and MF alleviated skin lesions and promoted positive histopathological changes in the hippocampus of AD mince to varying degrees. MLCD however, could further increase their proportion of open arm entry times (Oentries%) in EPM, residence time in the central area (Ctime) and the proportion of the number of times in the central area (Centries%) in OFT significantly. MLCD also reduces their immobility time in TST considerably. Mechanistically, MLCD downregulated the relative mRNA expression and protein level of NLRP3, Caspase-1, IL-1 beta, and IL-18 in hippocampal tissue compared to the model group.Conclusions: MLCD can alleviate anxiety-like and depression-like behaviors in AD mice by intervening in the gene and protein expression of NLRP3 inflammasome-related factors, thus treating AD.
Ethnopharmacological relevance: Shuyu decoction (SYD), an effective traditional Chinese medicine (TCM), has been widely used for treating deficiency-related diseases for thousands of years. Meanwhile, exercise-induced fatigue (EF), a common physiological phenomenon observed in physical training, has been treated as a deficient condition in TCM for decades. Currently, not many studies have been conducted on the effect of SYD on EF and little is known about its underlying pharmacological mechanism.Aim of the study: This current study was designed to assess the anti-fatigue roles of SYD and explore its effect on exercise-induced immune dysfunction.Materials and methods: Eighteen rats were randomly divided into three groups: normal control (NC) group, model (M) group, and SYD group (27.8 g/kg). The M and SYD group were given treadmill training for 6 weeks. From the fourth week, the SYD group was administered SYD intragastrically for 3 consecutive weeks. After three weeks of treatment, the rats were anesthetized, and the blood and spleen tissue samples were dissected. The blood sample was devoted to the blood biochemical-related indicators, which were used to evaluate the anti-fatigue of SYD. The expression of Interleukin (IL)-6, IL-18, tumor necrosis factor-alpha (TNF-alpha), IL -17, CD3(+), and CD4(+) were detected by ELISA and the level of CD8+ of blood was measured through Flow Cytometry (FC). The histopathological changes of spleen tissue samples were determined by Hematoxylin and eosin (H&E) staining and an estimation of CD3(+), CD4(+), and CD8(+) expression of spleen tissues were calculated through FC.Results: Compared with the M group, the SYD group observed an increase in tensile force and the ratio of cortisol to testosterone (TTE/COR), whereas a reduction in the levels of lactic acid (LAC), blood urea nitrogen (BUN), creatine kinase (CK), (P < 0.01 or P < 0.05). ELISA experiments showed that SYD reduced the expressions of IL-6, IL-18, and TNF-alpha, IL-17 and increased the expression of IL-10 (P < 0.01 or P < 0.05). In the HE test, SYD treatment transformed the structure of the spleen. FC experiments further showed that SYD increased the expressions of CD3(+), CD4(+), and CD8(+) in blood and spleen tissues (P < 0.01 or P < 0.05).Conclusion: Our findings indicate that SYD can alleviate EF by improving inflammation and immunity. However, the relationship between inflammatory factors and the related immune response remains to be further investigated.
Objective: To observe the effects of Danggui Shaoyao powder (DSP) on hepatic lipid metabolism and further explore its mechanism of action by peroxisome proliferator-activated receptor (PPARγ)-liver X receptor (LXRα)-adenosine triphosphate (ATP)-binding cassette transporter A1 (ABCA1) pathway regulation. Methods: Eight C57BL/6J male mice were selected as the control group, and 24 ApoE−/− male mice were randomly divided into the atherosclerosis model (AS) group, atorvastatin calcium (AC) group, and DSP group (n = 8 each group). To establish an AS model, ApoE−/− mice were fed a high-fat diet for 16 weeks. Pathologic changes in the aortic vasculature and liver were identified using Oil Red O staining. Triglyceride (TG), cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) levels were determined in the livers using a single-reagent GPO-PAP method. Fluorescence quantitative polymerase chain reaction and western blot were used to observe and evaluate the mRNA and protein expression of the PPARγ-LXRα-ABCA1 intermediates in the liver. Results: After 16 weeks of a high-fat diet, ApoE−/− mice showed more Oil Red O staining in the aorta and liver compared to the CONT group. Compared to the AS group, the DSP and AC treatment reduced aortic plaque and hepatic lipid deposition to varying degrees. Furthermore, DSP significantly reduced the hepatic lipid area in ApoE−/− mice (P < .001) and decreased the levels of TG, TC, and LDL-C in liver (P < .001, P = .027, P < .001, respectively). DSP also significantly increased the levels of PPARγ, LXRα, ABCA1, and ABCG1 mRNA expression, as well as the PPARγ, LXRα, ABCA1, and ABCG1 protein expression in liver. Conclusion: DSP improved hepatic lipid metabolism via PPARγ-LXRα-ABCA1 pathway modulation for AS treatment.
Objective: To explore the mechanism of Huatan Sanjie Fang(HTSJ) in regulating goiter in Graves’ disease(GD) mice by detecting key factors of the Hippo signaling pathway.Methods: A mouse model of GD was established by injecting Ad-TSHR289 adenovirus into the bilateral quadriceps femoris of female mice. Successful mouse models were then randomly divided into a model group, methimazole(MMI) group, and HTSJ group, and fed with deionized water, MMI(4.5 mg/kg per day), and HTSJ(35.10 g/kg per day), respectively, for 10 weeks. Histopathological changes of the thyroid gland were subsequently observed by hematoxylin-eosin staining. Radioimmunoassay was used to detect serum total thyroxine(T4) and thyrotrophin-receptor antibody(TRAb) levels. The relative expression of mRNA of Mst1, YAP, and TAZ were detected by quantitative real-time polymerase chain reaction, while the protein expression of Mst1, YAP, TAZ, pMst1, and pYAP were detected by western blot.Results: After 10 weeks of drug intervention, goiter and other pathological changes in the HTSJ group significantly improved compared with the model group, and the levels of serum T4 and TRAb significantly decreased(P =.002, P <.001, respectively). Decreased mRNA expression of Mst1, YAP, and TAZ, the key factors of the Hippo signaling transduction pathway, was also observed(P =.002, P =.022, P <.001,respectively). In contrast, protein expression of Mst1(P =.046), pMst1(P =.026), and p YAP(P =.004)increased, while protein expression of YAP and TAZ decreased(P =.041, P <.001, respectively).Conclusion: HTSJ can effectively improve goiter in GD mice through the Hippo signaling pathway.
Objective: To investigate the efficacy and mechanism of Mahuang Lianqiao Chixiaodou decoction (MLCD) in intervening in the “internal and external crosstalk” between skin barrier dysfunction and immune inflammation in an atopic dermatitis-like (AD-like) mouse model via the NOD-like receptor protein 3 (NLRP3) pyroptosis pathway. Methods: AD-like model mice were induced with 2,4-dinitrofluorobenzene and treated with MLCD or mometasone furoate gel (MF, positive control) for 7 days. Pathological changes in skin tissue were examined using Masson or methamphetamine blue staining. A smart skin analyzer, flow cytometry, fluorescence quantitative polymerase chain reaction, and western blotting were used to observe and evaluate skin barrier dysfunction, immune inflammatory responses, and skin cell pyroptosis in AD-like mice. Results: MLCD and MF improved skin damage and reduced pathological tissue damage and mast cell infiltration in AD-like mice to varying degrees. MLCD significantly reduced skin pigmentation and inflammatory status (P = .005 and P = .038, respectively), increased the percentage of splenic CD4+CD3+ T cells (P = .022), decreased the CD8+CD3+ T cell percentage (P = .044), decreased the CD8+CD3+/CD3+ ratio (P = .031) and increased the CD4+CD3+/CD8+CD3+ ratio (P = .027). MLCD also significantly decreased the mRNA expression levels of cell scorch-related factors NLRP3, casp-1, interleukin (IL)-1β, and IL-18 (P = .027, P < .001, P = .012, and P = .039, respectively), as well as the protein expression of NLRP3, casp-1, apoptosis-associated speck-like protein containing a CARD, and IL-1β (P = .002, P = .006, P = .004, and P = .035, respectively). Conclusion: MLCD achieved efficacy in the treatment of AD-like mice by interfering with the “internal and external crosstalk” mechanisms of skin barrier dysfunction and immune inflammation mediated by NLRP3 pyroptosis.

Background: The medical records of traditional Chinese medicine(TCM) contain numerous synonymous terms with different descriptions,which is not conducive to computer-aided data mining of TCM. However, there is a lack of models available to normalize synonymous TCM terms. Therefore, construction of a synonymous term conversion(STC) model for normalizing synonymous TCM terms is necessary.Methods: Based on the neural networks of bidirectional encoder representations from transformers(BERT), four types of TCM STC models were designed: Models based on BERT and text classification, text sequence generation, named entity recognition, and text matching. The superior STC model was selected on the basis of its performance in converting synonymous terms. Moreover, three misjudgment inspection methods for the conversion results of the STC model based on inconsistency were proposed to find incorrect term conversion: Neuron random deactivation, output comparison of multiple isomorphic models, and output comparison of multiple heterogeneous models(OCMH).Results: The classification-based STC model outperformed the other STC task models. It achieved F1 scores of 0.91, 0.91, and 0.83 for performing symptoms, patterns, and treatments STC tasks, respectively. The OCMH method showed the best performance in misjudgment inspection, with wrong detection rates of 0.80, 0.84, and 0.90 in the term conversion results for symptoms, patterns, and treatments, respectively.Conclusion: The TCM STC model based on classification achieved superior performance in converting synonymous terms for symptoms,patterns, and treatments. The misjudgment inspection method based on OCMH showed superior performance in identifying incorrect outputs.

ObjectiveTo reveal the mechanism of Mahuang Lianqiao Chixiaodou decoction and its disassembled formula for improving the skin barrier function in a mouse model of atopic dermatitis (AD).MethodsSixty specific-pathogen free male BALB/c mice were randomly divided into the control group, model group, whole formula group (WF), exterior-releasing formula group (ERF), interior-clearing formula group (ICF), and positive control group (PC). A mouse model of AD was established using the semi-antigen 2, 4-dinitrofluorobenzene induction method. The lesion scores, transepidermal water loss and pH, and skin histopathology of mice in each group were observed. The expressions of filaggrin, loricrin, and involucrin were detected by the streptavidin peroxidase immunohistochemical method and western blotting, and their mRNA expressions were detected by quantitative polymerase chain reaction.ResultsMice in the WF, ERF, ICF, and PC groups showed reduced skin lesion performance, improved histopathology, decreased skin lesion score, transepidermal water loss and pH, and upregulated expressions of proteins including filaggrin, loricrin, and involucrin, and their mRNAs. The most obvious regulatory effect was observed in the WF group, followed by the ICF, ERF, and PC groups, accordingly.ConclusionsMahuang Lianqiao Chixiaodou decoction and its disassembled formula can improve the skin barrier function in a mouse model of AD by upregulating filaggrin, loricrin, and involucrin, and their mRNA expressions, and the most optimal effect was noted in the WF group, followed by the ICF and ERF groups, which suggests that the effect of clearing heat and resolving dampness in improving the skin barrier function of AD is more obvious and is one of the key treatments for AD.

Background The modernization of traditional Chinese medicine (TCM) demands systematic data mining using medical records. However, this process is hindered by the fact that many TCM symptoms have the same meaning but different literal expressions (i.e., TCM synonymous symptoms). This problem can be solved by using natural language processing algorithms to construct a high-quality TCM symptom normalization model for normalizing TCM synonymous symptoms to unified literal expressions. Methods Four types of TCM symptom normalization models, based on natural language processing, were constructed to find a high-quality one: (1) a text sequence generation model based on a bidirectional long short-term memory (Bi-LSTM) neural network with an encoder-decoder structure; (2) a text classification model based on a Bi-LSTM neural network and sigmoid function; (3) a text sequence generation model based on bidirectional encoder representation from transformers (BERT) with sequence-to-sequence training method of unified language model (BERT-UniLM); (4) a text classification model based on BERT and sigmoid function (BERT-Classification). The performance of the models was compared using four metrics: accuracy, recall, precision, and F1-score. Results The BERT-Classification model outperformed the models based on Bi-LSTM and BERT-UniLM with respect to the four metrics. Conclusions The BERT-Classification model has superior performance in normalizing expressions of TCM synonymous symptoms.
