조효선, Cho. Hyo-Sun 한국미생물학회 미생물학회지 6 Pages

표면의 PD-L (program death ligand) 1 발현은 T림프구의 활성을 감소시켜 면역조절의 가능성이 있음을 시사하였다. 또한, HCV 특이 tetramer 반응은 T 림프구의 과도한 활성으로 자기사멸(apoptosis)의 경로에 있음을 caspase 3 활성으로 확인하였고, 역시 PD-L1의 발현이 T 림프구를 자기사멸(apoptosis)로부터 구제하여 caspase 3 활성이 감소하는 것을 확인하였다. 이는 PD-L1과 간성(liver) T 림프구 표면의 PD-1 결합이 T 림프구의 자기사멸을 막고, 또한 그 기능을 회복시켜 만성 C형 간염 치료에 응용될 수 있음을 시사한다. -

T-cell rich areas but rarely in B cell rich areas. IL-10 was highly expressed in bystander cells but rarely in PCV2-infected cells. Elevated IL-10 expression was predominantly associated with T cells, but rarely with B cells or with macrophages. The results of this study provide evidence for the role of IL-10 in chronic PCV2 infection and its relation to PCV2 antigen in affected tissues. Constantly elevated levels of IL-10 lead to immunosuppression in persistent and chronic viral infections. The... -
C형 간염 바이러스 감염 간암 세포주와 T 림프구의 상호작용에 대한 연구

culture system)이 확립되었다. 본 연구에서는 인간 간암세포주 중 huh7.5 cell (human hepatoma 7.5 cells)과 C형 간염 바이러스인 J6/JFH1 clone (2a 유전자형)를 이용하여 감염 가능한 세포배양모델을 확립하였다. 또한, HCV 감염 간암세포주의 HCV 특이 T 림프구에 대한 항원제시(antigen presentation) 가능성을 살펴보았다. 외부에서 전달된 HCV 항원일 경우 간암세포주의 HCV 특이 T 림프구에 대한 항원제시로 T 림프구의 활성이 가능하였으나, HCV 감염 간암세포주의 경우 T 림프구의 활성을 억제하였다. 이러한 HCV 특이 T... -
Recombinant Kluyveromyces lactis expressing highly pathogenic porcine reproductive and respiratory syndrome virus GP5 elicits mucosal and cell-mediated immune responses in mice

was generated and immune responses to this construct were analyzed in mice. Intestinal mucosal PRRSV-specific sIgA antibody and higher levels of IFN-γ in spleen CD4 and CD8 T cells were induced by oral administration of Yeast-GP5. Additionally, Yeast-GP5 administered subcutaneously evoked vigorous cell-mediated immunity, and PRRSV-specific lymphocyte proliferation and IFN-γ secretion were detected in the splenocytes of mice. These results suggest that Yeast-GP5 has the potential for use as a... -
Cyclophilin A as a New Therapeutic Target for Hepatitis C Virus- induced Hepatocellular Carcinoma
JinhwaLee 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 9 Pages

Hepatocellular carcinoma (HCC) related to hepatitis B virus (HBV) and hepatitis C virus (HCV) infections is thought to account for more than 80% of primary liver cancers. Both HBV and HCV can establish chronic liver inflammatory infections, altering hepatocyte and liver physiology with potential liver disease progression and HCC development. Cyclophilin A (CypA) has been identified as an essential host factor for the HCV replication by physically interacting with the HCV non structural protein... -
Toward the development of a one-dose classical swine fever subunit vaccine

Highly contagious classical swine fever (CSF) remains a major trade and health problem in the pig industry, resulting in large economic losses worldwide. In CSF-endemic countries, attenuated CSF virus (CSFV) vaccines have been routinely used to control the disease. However, eradication of CSFV in a geographical area would require permanent reduction to zero presence of the virus. It is therefore of paramount importance to develop a safe, potent, and non-infectious CSF vaccine. We have previously... -

(T-1, n=10), a diet mixed with SuperFeed as 3% (w/w) in a final concentration (T-2, n=10), or a diluted PowerFeel solution (1:500, v/v) as drinking water (T-3, n=10), respectively. A group (n=10) served as a non-treated control. Proportions of expressing CD2+ and CD8+ cells increased significantly (p<, 0.05) at 8-week post-application. Mean antibody titers of each group against HCV gradually increased to higher levels after vaccination and with challenge of the virulent virus. In conclusion, the... -

by a flow cytometry and HCV-specific antibody was determined by an indirect immunofluorescence assay. In IMAC-treated groups, the proportions of subpopulation expressing MHC-class II, CD2+, CD4+, CD8+, and surface IgM+ B lymphocytes were significantly decreased at 5-weeks after the first vaccination. Significant decreases were also observed in the proportions of MHC-class II, CD2+ and CD8+ lymphocyte at 3-weeks after the booster injection. The humoral immune responses in T-1 and T-2 groups were...
