  • Asthma is a chronic airway inflammatory disease characterized by reversible airway obstruction and airway hyperreactivity to various environmental stimuli, leading to recurrent cough, dyspnea, and wheezing episodes. Regarding inflammatory mechanisms, type 2/eosinophilic inflammation along with activated mast cells is the major one; however, diverse mechanisms, including structural cells-derived and non-type 2/neutrophilic inflammations are involved, presenting heterogenous phenotypes. Although most asthmatic patients could be properly controlled by the guided treatment, patients with severe asthma (SA; classified as a treatment-refractory group) suffer from uncontrolled symptoms with frequent asthma exacerbations even on regular anti-inflammatory medications, raising needs for additional controllers, including biologics that target specific molecules found in asthmatic airway, and achieving the precision medicine for asthma. This review summarizes the immunologic basis of airway inflammatory mechanisms and current biologics for SA in order to address unmet needs for future targets.

  • Background: It is not clear whether ginseng affects cyclosporine A (CsA)-induced desirable immunosuppressive action. In this study, we evaluated the immunological influence of combined treatment of ginseng with CsA. Methods: Using CD4+ T cells from mouse spleens stimulated with the T cell receptor (TCR) or allogeneic antigen-presenting cells (APCs), we examined the differentiation of naïve T cells into T helper 1 (Th1), Th2, Th17, and regulatory T cells (Tregs), and their cytokine production during treatment by Korean Red Ginseng extract (KRGE) and/or CsA. The influence of KRGE on the allogeneic T cell response was evaluated by mixed lymphocyte reaction (MLR). We also evaluated whether signal transducer and activator of transcription 3 (STAT3) and STAT5 are implicated in this regulation. Results: Under TCR stimulation, KRGE treatment did not affect the population of CD4+interferon gamma ($IFN{\gamma}$)+ and CD4+interleukin (IL)-4+ cells and their cytokine production compared with CsA alone. Under the Th17-polarizing condition, KRGE significantly reduced the number of CD4+IL-17+ cells and CD4+/phosphorylated STAT3 (p-STAT3)+ cells, but increased the number of CD4+CD25+forkhead box P3 (Foxp3)+ cells and CD4+/p-STAT5+ cells compared with CsA alone. In allogeneic APCs-stimulated CD4+ T cells, KRGE significantly decreased total allogeneic T cell proliferation. Consistent with the effects of TCR stimulation, KRGE reduced the number of CD4+IL-17+ cells and increased the number of CD4+CD25+Foxp3+ cells under the Th17-polarizing condition. Conclusion: KRGE has immunological benefits through the reciprocal regulation of Th17 and Treg cells during CsA-induced immunosuppression.

  • Objectives: This sutdy aims to research the trend of the studies related with acupuncture treatment of asthma. Methods: We searched the electronic database and reviewed ReT studies comparing the effect of sham and real acupuncture published after 2000 Results: We selected eight articles. Effectiveness of asthma acupuncture treatment was generally insufficient. Three articles reported acupuncture to be effective in subjective symptoms and quality of life. Other three articles reported that acupucture treatment was moderately effective but, insignificant compared to sham acupuncture treatment. Some articles reported that acupucture treatment was significant in the decrease of drug dosage and immunologic regulation. Conclusion : For the study on acupuncture treatments in asthma, it is necessary that we conduct research on the various natures of acupuncture. More clinical data would be needed to prove the effects of acupuncture treatment in asthma.

  • Mucous membrane pemphigoid is uncommom disease in oral cavity and synonymous with cicatricial pemphigoid. This disease is caused by autoimmune reaction that autoantibody reacts antigen located in basement membrane and epithelium is separated from underlying connective tissue. It affects female over sixth decade, commonly. Oral mucosa, especially gingiva is common site but conjunctival, nasal, pharyngeal, laryngeal, esophageal, varginal mucosa and skin are involved. Intraoral findings show Nikolsky sign, irregular erythema, erosion, vesicle, and ulceration at mucous membrane. To differentiate from diseases of positive Nikolsky sign, should perform histologic, immunologic test. Histologic features show subbasilar cleft and direct immunologic features show IgG, C3 deposits at basement membrane in linear pattern. Mucous membrane pemphigoid is incurable disease because symptoms are repetitively improved or worsed for several years. Patiens are commonly managed with topical and systemic steroid. To avoid side effects of prolonged steroid therapy and to maintain immunosupressive effects, combination therapy of azathioprine with steroid is effective. This case reports that mucous membrane pemphigoid is diagnosed based on clinical and histologic features, is treated with topical, systemic steroid and azathioprine therapy.

  • A case of pulmonary aspergillosis, strongly suspected before operation and confirmed after surgical intervention, was reviewed with related literatures. It has become to be a well recognized fact that pulmonary mycosis generally results from sapro-phytic colonization of previous lung cavities usually due to pulmonary tbc, lung abscess, cyst of bronchiectasis. Recently, the author experienced one case of pulmonary aspergillosis which had been diagnosed and treated as tuberculosis for 6 years. Sputum culture, immunologic study and X-ray findings constitute essential part of diagnosis. Surgical resection is the treatment of choice combined with systemic administration of anti-fungal agents to eradicate the disease completely.

  • Yanhyeoljeseuptang(YHJST) is a traditional herbal medicine used for the treatment of dermatitis. The aim of this study was to confirm whether or not YHJST has a preventive effect on development of atopic dermatitis in dinitrochlorobenzene(DNCB)-applied Nc/Nga mouse. This study was undertaken to develop a reliable mouse model demonstrating similar immunologic phenomena as human atopic dermatitis characterized with predominance of type-2 immune response. NC/Nga mouse were sensitized with $200\;{\mu\ell}$ of 1% 2,4-dinitrochlorobenzene(DNCB) (acetone : olive oil = 3 : 1 mixture) and challenged twice or three times with $150\;{\mu\ell}$ of 0.2% DNCB in a week for the following 4 weeks. YHJST was administered orally to Nc/Nga mouse for 8 weeks, which led to the remarkable suppression on the development of dermatitis, as determined by various immune factors related to pathogenesis of atopic dermatitis in splenocytes and DLN cells. In this study, YHJST selectively suppressed T ce11 (CD4+, CD3+/CD69+, CD4+/CD25+) activation, which may be essential for ratio of IL-4 versus INF-$\gamma$ produced in the splenic T cell culture supernatants was approximately 3-fold higher in the mouse treated with DNCB than their control mouse respectively. Immunologic studies showed down-regulated that the capacity of spleen T cells to produce IL-4, but IFN-$\gamma$ was up-regulated by means of oral intake of these YHJST. These results strongly suggest that YHJST is a promising candidate for treatment of human atopic dermatitis.

  • Periapical lesions are developed as a result of inflammatory response to irritants from root canal system. Clinicians remove these irritants from root canal system and seal the root canal space to induce healing of the periapical lesions. Immunopathologic responses may play an important role in development and progression of periapical lesions and periapical lesions contain immunocompetent cells. The purposes of the present study were to analys and to compare the distribution of the immunocompetent cells in the human periapical lesions according to the stage of endodontic treatment using indirect immunoperoxdase technique. Obtained 94 human periapical lesions were devided into four groups: Group 1 : no endodontic treatment(28 samples) Group 2 : root canal enlarged and irrigated(28 samples) Group 3 : root canal filled(29 samples) Group 4: unknown(9 samples) Monoclonal antibodies to examine target cells were UCHL-1 for T lymphocytes(1 : 200, Dakopatt, Denmark), L26 for B lymphocytes(1 : 200, Dakopatt, Denmark), OPD4 for helper T lymphocytes(l : 200, Dakopatt, Denmark) and alpha-1-antichymotrypsin for macrophages(l : 2000, Dakopatt, Denmark). The following results were obtained : 1. All the periapical lesions studied were infiltrated by T lymphocytes, plasma cells, B lymphocytes, and macrophages. T lymphocytes were more infiltrated than B lymphocytes, and B lymphocytes and macrophages were less infiltrated than T lymphocytes and plasma cells(P<0.05 : Oneway ANOVA test). 2. In untreated group and canal irrigated and enlarged group of all the periapical lesions, helper T lymphocytes were predominently infiltrated(P>0.05 : Oneway ANOVA test). 3. In canal filled groups of all lesions except periapical cyst, plasma cells were predominently infiltrated. But, in canal filled group of periapical cyst, helper T lymphocytes were the predominent cells(P>0.05 : Oneway ANOVA test). The above results shows that the immunologic responses play important role in pathogenesis of periapical lesions and the immunologic response involved undergoes certain changes after endodontic therapy.
