  • Immunosuppressors cyclosporine A(CsA) and tacrolimus(FK506), the primary cellular target of which is calcineurin/nuclear factor of activated T cells(NFAT) signalling pathways, decrease beta-cell insulin content and mRNA expression. The posttransplantation diabetes mellitus(PTDM) is a frequent complication in immunosuppressive therapy. The present study was to examine the effect of a crude water extracts of medicinal herbs such as Sanguisorba officinalis(SOE) on the immunosuppressive activity with lymphocyte and insulin secretion in insulinoma cell lines with RIN-5mF. It was found that SOE treatment had effect of immunosuppressor on lymphocytes and also significantly increased insulin secretion in RIN-5mF compared to other agents. we might suggest a mechanism on insulin secretion by HNF4a. Taken together, the present study suggested that SOE might serve as immunosuppressive drug in PTDM.

  • The objective of the present study was to investigate the survival effect after transplantation of pig spermatogonia cells into mouse testis. Donor cells were collected from porcine testis and the isolated spermatogonial stem cells were labeled with a fluorescent marker before transplantation and transplanted into testes of busulfan-treated recipient mice. Testes were examined for the presence and localization of labeled donor cells immediately after transplantation or every week for 4 wk. Transplanted germ cells were present in the seminiferous epithelium at 4 weeks after the transplantation, but any differentiating porcine-derived cells were not detected in mouse testis. These results indicate that porcine-derived spermatogonial stem cells can be survived in the recipient, but suggest that porcine-derived male stem cells can not proceed to further differentiating step without helping of immunosuppressor agents.

  • Developing new substance for immunosuppressor or immunomodulator from natural products is extremely important in the present biomedicine. In this paper, we focused our efforts on the mitogenicity and immunochemical properties of the two lectins (LCC-I, LCC-II) obtained from marine animal Lunella coronata coreensis. Immunochemical techniques were employed to elucidate the structural and/or functional similarities between the LCC lectins. Molecular weight of the LCC lectins, LCC-I and LCC-II were estimated to be around 60 KD and 66-70 KD, respectively. LCC lectins were mitogens for murine splenic lymphocytes, and the optimum mitogenic doses were 31.25 $\mu\textrm{g}$/ml and 3.91 $\mu\textrm{g}$/ml, respectively. LCC-II lectin was a good mitogen toward human peripheral lymphocytes at a concentration about 31.25 $\mu\textrm{g}$/ml.

  • Cyclosporine A (CsA) is a potent immunosuppressor that is widely used in transplant surgery and the treatment of several autoimmune diseases. However, major side effects of CsA such as nephrotoxicity, hepatotoxicity, neurotoxicity and cardiovascular diseases have substantially limited its usage. Although molecular mechanisms underlying these adverse effects are not clearly understood, there is some evidence that suggests involvement of reactive oxygen species (ROS). In parallel, protective effects of various antioxidants have been demonstrated by many research groups. Extensive studies of CsA-induced nephrotoxcity have confirmed that the antioxidants can restore the damaged function and structure of kidney. Subsequently, there have appeared numerous reports to demonstrate the positive antioxidant effects on liver and other organ damages by CsA. It may be timely to review the ideas to envisage the relationship between ROS and the CsA-induced toxicity. This review is comprised of a brief description of the immunosuppressive action and the secondary effects of CsA, and a synopsis of reports regarding the antioxidant treatments against the ROS-linked CsA toxicity. A plethora of recent reports suggest that antioxidants can help reduce many CsA's adverse effects and therefore might help develop more effective CsA treatment regimens.

  • Psoriasis is a chronic inflammatory disease of the skin characterized by epidermal hyperplasia, dermal angiogenesis, infiltration of activated T cells, and increased cytokine levels, and affects 1-3% of the world-wide population. Although many immunological and clinical reports indicate a role for the immune system in the pathogenesis of psoriasis, puzzling questions about psoriasis remain unsolved. During the several decade, immunosuppressor and PUVA treatment are ubiquitously used to psoriasis therapy. But recently, to promote terminal differentiation of keratinocytes, block either NK-Tcell or T-cell activation, and interrupting the angiogenic switch represent another therapeutic opportunity in psoriasis. To keep face with immunological therapy, the needs of newly designed prescription on the psoriasis treatments were demanded. With the object of understand the psoriasis from an orient medical point of view, patients were administrated the GY during several weeks. We investigated the changes of gene expression in involved and uninvolved skin samples during the oriental remedy. Microarray data showed several important results. First, Gene expression profiling is similar to each patient. Second, precursor proteins that organize cornified envelops are decreased at the end of remedy. But genes which related to apoptosis, G-protein signalling, and lipid metabolism are increased. Third, 68.5% of clustering genes localized on the psoriasis susceptibility locus. In our results indicated that GY influence on the keratinocytes hyperproliferation by regulating the gene, which located on the psoriasis susceptibility locus.

  • The 12 kDa FK506-binding protein (FK506BP12), an immunosuppressor, modulates T cell activation via calcineurin inhibition. In this study, we investigated the ability of PEP-1-FK506BP12, consisting of FK506BP12 fused to the protein transduction domain PEP-1 peptide, to suppress catabolic responses in primary human chondrocytes and in a mouse carrageenan-induced paw arthritis model. Western blotting and immunofluorescence analysis showed that PEP-1-FK506BP12 efficiently penetrated chondrocytes and cartilage explants. In interleukin-1β (IL-1β)-treated chondrocytes, PEP-1-FK506BP12 significantly suppressed the expression of catabolic enzymes, including matrix metalloproteinases (MMPs)-1, -3, and -13 in addition to cyclooxygenase-2, at both the mRNA and protein levels, whereas FK506BP12 alone did not. In addition, PEP-1-FK506BP12 decreased IL-1β-induced phosphorylation of the mitogen-activated protein kinase (MAPK) complex (p38, JNK, and ERK) and the inhibitor kappa B alpha. In the mouse model of carrageenan-induced paw arthritis, PEP-1-FK506BP12 suppressed both carrageenan-induced MMP-13 production and paw inflammation. PEP-1-FK506BP12 may have therapeutic potential in the alleviation of OA progression. [BMB Reports 2015; 48(7): 407-412]

  • 인삼 saponin이 면역작용에 미치는 영향을 알아보기 위하여 생쥐에 단백질 항원(암닭의 ${\gamma}$-globulin)으로 면역시킨 후 1차 면역후 10일, 2차 면역후 10일에 각각 채혈하여 혈청내의 항체가를 ELISA(enzyme linked immunosorbent assay) method로 측정하였고, 또한 같은 항원으로 면역시킨 생쥐에 면역억제제를 사용하여 생쥐의 면역제를 억제시킨 후 그 회복에 미치는 영향을 알아보기 위하여 같은 방법으로 항체가를 측정하였다. 인삼 saponin을 투여한 실험군(10mg/ kg/day)은 개체에 따라 약간의 차이는 있었으나 같은 조건의 생리식염수 투여군보다 각각 훨씬 높은 항체가를 나타내었고, 면역억제제에 의한 면역억제의 회복에 있어서도 유의성있는 회복효과를 나타내었다. 따라서 면역작용에 미치는 인삼saponin의 영향은 정확한 기작은 밝혀지지 않았으나 인삼 saponin이 혈청단백질 합성을 증가시키는 효과와 함께 일종의 면역자극제(immunostimulator)로 작용하고 있는 것으로 생각된다.
