The mir-155 family is not only involved in a diversity of cancers, but also as a regulator of the immune system. However, the evolutionary history of this family is still unclear. The present study indicates that mir-155 evolved independently with lineage-specific gain of miRNAs. In addition, arm switching has occurred in the mir-155 family, and alternative splicing could produce two different lengths of ancestral sequences, implying the alternative splicing can also drive evolution for intragenic miRNAs. Here we screened validated target genes and immunity-related proteins, followed by analyzation of the mir-155 family function by high-throughput methods like the gene ontology (GO) and Kyoto Eneyclopedin of Genes and Genemes (KEGG) pathway enrichment analysis. The high-throughput analysis showed that the CCND1 and EGFR genes were outstanding in being significantly enriched, and the target genes cebpb and VCAM1 and the protein SMAD2 were also vital in mir-155-related immune reponse activities. Therefore, we conclude that the mir-155 family is highly conserved in evolution, and CCND1 and EGFR genes might be potential targets of mir-155 with regard to progress of cancers, while the cebpb and VCAM1 genes and the protein SMAD2 might be key factors in the mir-155 regulated immune activities.

There is a growing consumer preference for self-medication, which has resulted in the growth of the Korean functional food market to \1.5 trillion in 2014. Functional foods that can modulate immune responses and enhance liver health are in the top 2 product-specific health functional food categories. The aim of this project was to develop and commercialize new health functional foods incorporated with Cordyceps militaris. Cordyceps genus includes about 400 species, many of which have been used as traditional medicines for many years in Asian countries. C. militaris belongs to the class Ascomycetes and has been used extensively as a crude drug and tonic food in East Asia. Owing to the various physiological activities of its main active constituent, cordyceptin, C. militaris is currently being used for multiple medicinal purposes. Recently, many studies have tried to elucidate the pharmacological mechanisms underlying the activities of Cordyceps spp., which include immune activation, anti-inflammatory, anticancer, and antiviral effects. After continuous attempts and research toward industrialization, C. militaris cultivated using brown rice was developed into a product by a standardized process and mass-cultivating system. It was successfully introduced into the market and was approved as a functional food ingredient for the first time in Korea. Based on this information, C. militaris containing functional food product for strengthening the immune system was released in August 2014 under the brand name "Dongchoong Ilgi." Dongchoong Ilgi is potentially beneficial for improving immune and liver functions and may enhance both the convenience and effectiveness of health functional foods taken by healthy people and patients with minor illness. In addition, the results of our study may be applicable for the development of health functional foods that could lower the risk of diseases such as the common cold and cancer.

Objective : Soybeans of Canavalia gladiata(CG) and root of Arctium lappa(AL) have been reported to have anti-inflammatory, antioxidant effect. However, the immunoregulatory mechanisms of its combinational prescription remain a matter of considerable debate. In the current study, we investigated whether CG and AL and its combinational prescription(CG+AL) regulate immune system using chronic immobilization-stress mouse model. Methods : C57BL/6J mice fixed for 2 hours into immobilization tube after CG, AL, CG+AL oral administration after 2 hours daily for 21 days. After every experiment has ended the C57BL/6J mice were sacrificed on 22 days. The production of Serotonin and Cortisol, lgA were observed by ELISA method, The proportion of immune cells such as T/B cell and macrophage, NK cell were measured by FACS. Then, Real-time PCR was performed to measure the mRNA expression of Inflammatory cytokines(IL-1beta, IL-6, TNF-a) and T cell activation cytokines(IL-2, IL-10, IFN-gamma, IL-12p35 / p40). Result : When chronic immobilization-stress mouse model were treated with CG+AL(1:4), the expression of mRNA were significantly decreased at the Inflammatory cytokines(IL-1beta, IL-6, TNF-a). While, the levels of mRNA were significantly increased at immune T cell activation cytokines. Additionally, CG+AL(1:4) combinational prescription group enhanced immune cells such as T/B cell and macrophage, NK cell. Furthermore, the Immuno-fluorescence result of brain tissue can confirm that CG+AL(1:4) group significantly increased the BDNF expression. Conclusion : These result suggest that CG+AL(1:4) combinational prescription has Immune System enhancement via stress-mediated immunocyte.

생균(Bacillus polyfermenticus, Bacillus mesentericus, Streptococcus faecalis, Bifidobacterium breve)과 소화 요소(protease, lipase)를 함유한 비스루트의 효과를 알아보기 위해 사료 내 1% 첨가하여 나일틸라피아 치어(19.0${\pm}$0.07g)에게 60일간 공급한 다음 성장률, 체조성 및 면역반응의 효과를 조사하였다. 60일간 사육한 결과 비스루트 첨가구와 대조구 사이에 유의적인 성장 차이를 보이지 않았지만(P>0.05), 보체의 용혈 능력은 비스루트 첨가구가 대조구에 비해 용혈능이 높은 것으로 조사되고 라이소자임의 용균 효과는 대조구와 비슷하였다. 식세포의 식작용 능력과 신장 마크로파지의 respiratory burst activity 는 비스루트 첨가구가 대조구에 비해 활성이 매우 높았다. 따라서 비스루트 사료 내 첨가가, 어류의 비특이적 면역 기능중에서 세포성 면역 기능을 활성화하는데 기여하였다. 병원성 세균 Edwardsiella tarda FSW 910410 균주로 공격 실험결과 비스루트 첨가구가 누적폐사율이 59%, 대조구가 80%로 조사되었고, 그 결과 비스루트 첨가구는 병원성 세균에 대한 저항력을 증가시켰다(P<0.05). Hematocrit, hemoglobin, total protein, glucose, GOT, GPT 와 같은 혈액 성분을 분석한 결과 비스루트 첨가구와 대조구 간의 유의차는 없었지만(P>0.05), glucose, GOT, GPT는 비스루트 첨가구가 대조구에 비해 낮게 나타났다. 이상의 결과로 비스루트는 나일틸라피아의 생리 기능에 문제를 야기시키지 않고, 비특이적 면역 기능 중 세포성 면역 기능을 증강시키는 효과가 있으며, 병원성 세균에 대한 저항력의 증강 효과도 높다. 따라서, 비스루트는 나일틸라피아의 사료 첨가물로서의 역할이 충분히 기대된다.

잉어의 선천성 면역 인자가 관여하는 항바이러스 면역 반응을 조사하기 위해 UV-inactivated SVCV, Poly I:C 및 Con A를 주사한 후 3일째 라이소자임 활성, 혈청 내 보체의 살균능력 및 식세포의 활성산소량을 조사하였다. 그 결과, 모든 시험구에서 혈청 내 라이소자임의 활성은 유의적인 차이를 나타나지 않았으나, 두신 조직의 라이소자임 활성은 대조구에 비해 유의적으로 증가하였다. 또한, 혈청 내 보체의 살균 능력도 모든 시험구에서 대조구와 유의적인 차이가 없었다. 그러나 식세포의 활성은 UV-inactivated SVCV 시험구에서는 농도에 따라 증가한 것으로 나타났으며, Poly I:C 및 Con A 시험구에서는 저농도에서 활성이 증가한 것으로 나타났다. 바이러스에 대한 방어력을 조사하기 위해 주사 후 4일째 1×104 TCID50/fish 농도의 SVCV로 인위 감염한 결과 UV-inactivated SVCV 및 Poly I:C 시험구에서는 Con A 시험구에 비해 높은 방어력을 나타내었다. 또한, Poly I:C 시험구에서 라이소자임 및 식세포 활성이 다소 감소한 고농도에서도 높은 방어력이 유도된 것으로 나타나 이러한 결과는 Poly I:C에 의해 자극된 또 다른 비특이적 면역 인자가 SVCV에 대한 방어반응에 관여한 것으로 추정된다.

Sepsis is a syndrome characterized by systemic inflammatory responses to a severe infection. Acute hyper-inflammatory reactions in the acute phase of sepsis have been considered as a primary reason for organ dysfunction and mortality, and advances in emergency intervention and improved intensive care management have reduced mortalities in the early phase. However it has been recognized that increased deaths in the late phase still maintain sepsis mortality high worldwide. Patients recovered from early severe illness are unable to control immune system with sepsis-induced immunosuppression such as immunological tolerance, exhaustion and apoptosis, which make them vulnerable to nosocomial and opportunistic infections ultimately leading to threat to life. Based on strategies to reverse immunosuppression, recent developments in sepsis therapy are focused on molecules having immune enhancing activities. These efforts are focused on defining and revising the immunocompromised status associated with long-term mortality.

A 3-year-old, 4.0 kg, intact male shih-tzu dog with anorexia, depression, pale mucous membranes, tachypnea, tachycardia was referred to the Veterinary Medical Teaching Hospital. Autoagglutination was observed by naked eye when blood was collected in an EDTA-tube and many spherocytes were found on a Diff-Quik stained blood smear. PCV was 6% and indirect bilirubin was increased markedly. So the immune-mediated hemolytic anemia was diagnosed. Autoagglutination was too severe to perform cross-matching test. Blood was not transfused as it might accelerate or precipitate hemolytic crisis, and regeneration of erythrocytes was very good. Thus corticosteroid of immunosuppressive dose and fluid were administered and PCV was monitored. Although blood was not transfused, PCV increased from 6 to 15.9% in a day and to 30% 7 days later. Therapy for liver was concurrently conducted because liver enzyme activities were high. Corticosteroid tappering therapy was conducted for 75 days and PCV was recovered to 46% after 4 months form start of the treatment.
