In this study, we examined the effect of Eucalyptus citriodora (Euc-c) extract on cytokine production, cell proliferation and cell differentiation in HaCaT cells to elucidate its influence on cutaneous homeostasis. Euc-c suppressed significantly LPS-induced IL-6 and TNF-a-induced IL-8 production from HaCaT cells. Conversely IL-1ra production was significantly enhanced by Euc-c. The expressions of IVL, CERS3 and CERS4, keratinocyte differentiation markers, were upregulated to 3.1, 2.8 and 2.7-fold respectively by Euc-c treatment, compared to the control, while the proliferation was downregulated. The lipid contents in Euc-c-treated cells tended to increase, compared with non-treated cells. To explore the underlying mechanism of these effect, we next performed siRNA experiments against PPAR-b/d. Euc-c enhanced PPAR-b/d mRNA expression to 3.25-fold, while PPAR-b/d mRNA expression in transfected cells was suppressed. The expressions of IVL, CERS3 and CERS4 in transfected cells were suppressed to 1.48, 0.82 and 0.72-fold respectively, concomitant with suppression of PPAR-b/d mRNA expression. These results indicated that Euc-c exerts anti-inflammatory effects and regulates keratinocyte differentiation via the modulation of PPAR-b/d pathway. Therefore, the application of Euc-c is expected to exert beneficial effect on skin disorders evoked by perturbation of skin homeostasis.Key words: Eucalyptus citriodora, PPAR-b/d, inflammation, barrier function, cutaneous homeostasis","PeriodicalId":401129,"journal":{"name":"Trends in Immunotherapy","volume":"186 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134095063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The recent approval of two CAR-T therapies by US Food and Drug Administration marked a very significant development in cell-based cancer immunotherapy. This milestone was demonstrated by the effectiveness of eradicating hematologic cancers using CD19-specific CARs. The success spurred development of immune cell therapies for other cancers, especially solid tumors. With regard to CAR-T therapy for solid tumors, although the clinical effects are limited, some unexpected serious adverse events have been reported and there are still many problems. The generation of novel CAR constructs for these cancer types represents a major challenge in bringing the technology ‘from-bench-to-bedside‘. In the review of Santos and Bernal[6], they outlined some new technologies to equip CAR-T cells to enhance efficiency while decreasing toxicity of CAR-T therapies in solid tumors. Development research on safer and more effective CAR-T therapy for solid tumors is in progress and will improve the outcome of treatment for patients with refractory leukemia and cancer in the future. Furthermore, it was expected that this CAR-T method would be applied to intractable autoimmune diseases. In the recent article of Kansal R et al[7], CD19-targeted CAR-T therapy is reported to be highly promising for intractable systemic lupus erythematosus. They used murine lupus models such as in the (NZB × NZW) F1 and MRL lpr/lpr mouse. New Zealand (NZ) mouse and MRL lpr/lpr mouse are well known to be a B-lupus model and a T-lupus model, respectively. The clinical trials of anti-CD20 antibody for lupus failed because of the transient and incomplete B cell depletion. They reported that CD8+ T cells expressing CD19-targeted CARs persistently depleted CD19+ B cells, eliminated autoantibody production, reversed disease manifestations in target organs, and extended life spans in murine lupus models. For human application, there will be many issues to be solved, but at least it will lead to the elucidation of the pathogenesis of intractable autoimmune diseases.

They are initially known as transcriptional regulators of lipid and glucose metabolism, although further evidence has also been accumulated for other functions. Due to the nature of all PPAR isotypes which are expressed and exert effects by regulating the functions of cell types residing and infiltrating in the skin, PPARs represent a major research target for the understanding and treatment of many skin diseases. Atopic dermatitis (AD) is a chronic and relapsing disease characterized by skin barrier dysfunction and immune dysregulation. Skin barrier disturbance is one of the exacerbation factors of AD, due to facile penetration of molecules such as antigens. From the aspect of immune dysregulation, innate and acquired immunity including cell proliferation, cell differentiation, and cytokine network are involved in the pathogenesis. In this review, the role of PPAR in AD and the possibility of its agonist for the treatment of AD are discussed.","PeriodicalId":401129,"journal":{"name":"Trends in Immunotherapy","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125420422","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This disease is characterized by remittent fever, pernio-like skin rashes, nodular erythema-like skin eruptions and partial lipodystrophy. NNS is an immunoproteasome-associated autoinflammatory disorder caused by a mutation of the PSMB8 gene. In general, autoinflammatory diseases are not associated with autoantibody production because it is assumed that autoinflammatory disorders are caused by the dysfunction of innate immunity and/or the dysfunction of proteasomes that have been collectively designated as proteasome-associated autoinflammatory syndromes. Autoinflammatory diseases were originally defined as diseases in which autoantibodies and autoreactive T cells were not detected, without activation of antigen-specific adaptive immune system, unlike autoimmune diseases. However, in recent years, as we previously reported, cases with the appearance of autoantibodies have been reported, and the boundaries are becoming vague. We herein discuss the relationship between ANA and autoinflammatory NNS. We collected 9 cases with NNS, in which 5 cases showed positive ANA or anti-dsDNA antibody during the course. The autoantibodies in NNS is also expected due to abnormal production and response of IFNα, but detailed pathological conditions need to be elucidated by accumulation and examination of further cases in the future. In other words, NNS will become a bridge with research on refractory autoimmune diseases.","PeriodicalId":401129,"journal":{"name":"Trends in Immunotherapy","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114216354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
