Background: This study examined the outcomes of ABO incompatible living donor liver transplantation (LDLT). The changes in the immunologic factors that might help predict the long term outcomes were also studied. Methods: Twenty-three patients, who underwent ABO incompatible LDLT from 2010 to 2015, were reviewed retrospectively. The protocol was the same as for ABO compatible LDLT except for the administration of rituximab and plasma exchange. The clinical outcomes and immunologic factors, such as isoagglutinin titer and cluster of differentiation 20+ (CD20+) lymphocyte levels were reviewed. Results: The center showed a 3-year survival of 64% with no case of antibody-mediated rejection. When transplantation-unrelated mortalities (for example, traffic accidents and myocardial infarction) were removed from statistical analysis, the 3-year survival was 77.8%. Although isoagglutinin titers continued to remain at low levels, the CD20+ lymphocyte levels recovered to the pre-Rituximab levels at postoperative one year. Conclusions: As donor shortages continue, ABO incompatible liver transplantation is a feasible method to expand the donor pool. On the other hand, caution is still needed until more long-term outcomes are reported. Because CD20+ lymphocytes are recovered with time, more immunologic studies will be needed in the future.

The pathophysiology and fundamental etiologic mechanism of inflammatory bowel disease (IBD) is not well understood even though therapeutic regimens and drugs are rapidly evolutionary. IBD has complicated connections with genetic, immunologic, gut microbial, environmental, and nutritional factors. It is not clearly well known to the physicians how to feed, what nutrients are more helpful, and what food to be avoided. This review discusses the issues of growth and important nutritional concerns in the management of IBD in childhood.

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.

The aim of this study was to confirm whether or not GPJST 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. GPJST was administered orally to Nc/Nga mouse for 6 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, GPJST 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.

Irritable bowel syndrome (IBS) is a frequently diagnosed gastrointestinal (GI) disorder characterized by recurrent abdominal pain, bloating, and changes in the stool form or frequency without any structural changes and overt inflammation. It is not a life-threatening condition but causes a considerable level of discomfort and distress. Among the many pathophysiologic factors, such as altered GI motility, visceral hypersensitivity, and low-grade mucosal inflammation, as well as other immunologic, psychologic, and genetic factors, gut microbiota imbalance (dysbiosis), which is frequently found in IBS, has been highlighted as an etiology of IBS. Dysbiosis may affect gut mucosal homeostasis, immune function, metabolic regulation, and even visceral motor function. As diet is shown to play a fundamental role in the gut microbiota profile, this review discusses the influence of diet on IBS occurring through the modulation of gut microbiota. Based on previous studies, it appears that dietary modulation of the gut microbiota may be effective for the alleviation of IBS symptoms and, also an effective IBS management strategy based on the underlying mechanism; especially because, IBS currently has no specific treatment owing to its uncertain etiology.

Memory CD8+ T cells in the immune system are responsible for the removal of external Ags for a long period of time to protect against re-infection. Naïve to memory CD8+ T cell differentiation and memory CD8+ T cell maintenance require many different factors including local environmental factors. Thus, it has been suggested that the migration of memory CD8+ T cells into specific microenvironments alters their longevity and functions. In this review, we have summarized the subsets of memory CD8+ T cells based on their migratory capacities and described the niche hypothesis for their survival. In addition, the basic roles of CCR7 in conjunction with the migration of memory CD8+ T cells and recent understandings of their survival niches have been introduced. Finally, the applications of altering CCR7 signaling have been discussed.

The prognosis of solitary plasmacytoma varies greatly, with some patients recovering after surgical removal or local fractional radiation therapy, and others progressing to multiple myeloma years later. Primary detection of progression to multiple myeloma is important in the treatment of solitary plasmacytoma. There have been several analyses of the risk factors involved in the early progression to multiple myeloma. We describe one case of solitary plasmacytoma of the lumbar vertebra that was treated with surgical decompression with stabilization and additional radiotherapy. The patient had no factors associated with rapid progression to multiple myeloma such as age, size, immunologic results, pathological findings, and serum free light chain ratio at the time of diagnosis. However, his condition progressed to multiple myeloma less than two months after the initial diagnosis of solitary plasmacytoma. We suggest that surgeons should be vigilant in watching for rapid progression to multiple myeloma even in case that the patient with solitary plasmacytoma has no risk factors for rapid progression to multiple myeloma.

Atopic dermatitis (AD) is a chronic inflammatory skin disease associated with cutaneous hyperreactivity to environmental triggers. The clinical phenotype that characterizes AD is the product of interactions between susceptible genes, the environmental factors, defective skin barrier function, and immunologic responses. This review summarizes recent progress in our understanding of the immunopathophysiology of AD and the implications for mouse models of AD in drug discovery from medicinal plants.

Although the exact mechanism responsible for the pathogenesis of psoriasis is unclear, interferon-${\gamma}$ producing type 1 T cells have been reported to play a significant role. Infiltrating activated type 1 T cells in the lesions are believed to be responsible for stimulating keratinocytes, which produce many cytokines and growth factors. The hyperproliferative epidermis is understood to be the result of either the cytokines produced by the intraepidermal T cells or the reactive phenomenon after keratinocyte damage. The microenvironment in psoriatic lesions deviates toward the type 1 status, because of the increased type 1 cytokines and either the decreased or unchanged type 2 cytokines observed in psoriatic lesions. Therefore, this review focused on a T-cell-mediated immunological basis for the current hypothesis of the psoriasis pathogenesis.
