About the Lab

Professor Eun Young Choi's research lab focuses on immunology and inflammatory disease mechanisms, with a central emphasis on leukocyte trafficking, T cell responses in transplantation and graft-versus-host disease, and the molecular regulation of immune cell adhesion and selection. The lab investigates key molecules such as Del-1 and CD99 in controlling leukocyte-endothelial interactions and thymic selection, while also exploring immunodominance in minor histocompatibility antigen responses. Their work bridges basic immunology with translational insights into inflammatory disorders and transplant rejection.

SJR Q1ScienceOA

Leukocyte recruitment to sites of infection or inflammation requires multiple adhesive events. Although numerous players promoting leukocyte-endothelial interactions have been characterized, functionally important endogenous inhibitors of leukocyte adhesion have not been identified. Here we describe the endothelially derived secreted molecule Del-1 (developmental endothelial locus-1) as an anti-adhesive factor that interferes with the integrin LFA-1-dependent leukocyte-endothelial adhesion. Endo

Mechanisms of neutrophil transendothelial migration
Eun Young Choi
Frontiers in bioscienceOA

Neutrophil recruitment is an integral part of the immune response to infection as well as of inflammatory disorders. The process of neutrophil extravasation comprises a complex multistep cascade that is orchestrated by a tightly coordinated sequence of adhesive interactions with vessel wall endothelial cells. Adhesion receptors as well as signaling molecules in both neutrophils and endothelial cells regulate the recruitment of neutrophils into the site of inflammation or infection. The present r

Quantitative Analysis of the Immune Response to Mouse Non-MHC Transplantation Antigens In Vivo: The H60 Histocompatibility Antigen Dominates Over All Others

SJR Q1The Journal of Immunology

Minor histocompatibility Ags (minor H Ags) are substantial impediments to MHC-matched solid tissue and bone marrow transplantation. From an antigenic standpoint, transplantation between MHC-matched individuals has the potential to be remarkably complex. To determine the extent to which the immune response is simplified by the phenomenon of immunodominance, we used peptide/MHC tetramers based on recently discovered minor H Ags (H60, H13, and HY) and monitored in vivo CD8 T cell responses of femal

SJR Q1BloodOA

Although CD8 T cells are thought to be a principal effector population of graft-versus-host disease (GVHD), their dynamics and specificity remain a mystery. Using a mouse model in which donor and recipient were incompatible at many minor histocompatibility antigens (minor H Ags), the CD8 T-cell response was tracked temporally and spatially through the course of GVHD. Donor CD8 T cells in the circulation, spleen, lung, and liver demonstrated virtually identical kinetics: rapid expansion and then

Engagement of CD99 Induces Up-Regulation of TCR and MHC Class I and II Molecules on the Surface of Human Thymocytes

SJR Q1The Journal of ImmunologyOA

CD99 is a cell surface molecule involved in the aggregation of lymphocytes and apoptosis of immature cortical thymocytes. Despite its high level expression on immature cortical thymocytes, the functional roles of this molecule during thymic selection are only now being elucidated. Examination of the effects of CD99 engagement on the expression kinetics of the TCR and MHC class I and II molecules, which are involved primarily in thymic positive selection, revealed a marked up-regulation of these

Regulation of LFA-1–dependent inflammatory cell recruitment by Cbl-b and 14-3-3 proteins

SJR Q1BloodOA

Inside-out signaling regulation of the beta2-integrin leukocyte function-associated antigen-1 (LFA-1) by different cytoplasmic proteins, including 14-3-3 proteins, is essential for adhesion and migration of immune cells. Here, we identify a new pathway for the regulation of LFA-1 activity by Cbl-b, an adapter molecule and ubiquitin ligase that modulates several signaling pathways. Cbl-b-/- mice displayed increased macrophage recruitment in thioglycollate-induced peritonitis, which was attributed

서울시 내부 인구이동의 특성에 관한 연구
최은영, 조대헌

본 연구에서는 서울시에서 발생하고 있는 인구이동의 대부분을 차지하는 도시내 인구이동의 지리적 특성을 밝히고, 아파트 평당 매매가를 통해 지역의 경제적 특성이 인구이동에 미치는 영향을 살펴보고자 한다. 구와 행정동을 분석 단위지역으로 인구이동을 가시화함으로써 밝혀진 서울시 내부 인구이동의 지리적 특성은 다음과 같다. 첫째, 거리가 증가함에 따라 인구이동은 급격하게 감소하였는데, 지배적인 인구이동은 대부분 인접 구와 인접 행정동 사이에서 발생함으로써 근거리이동이 탁월하게 관찰되었다. 둘째, 근거리이동의 지배적인 패턴은 인접한 모든 지역이 아니라 특정 지역 사이에서 관찰되는데, 특히 한강과 학군이 주요한 경계로 나타나고 있다. 셋째, 분석 단위지역에 따라 상이한 인구이동 패턴이 나타나고 있다. 이와 동시에 행정동별 아파트 평당 매매가의 차이는 인구이동의 발생 및 이동인구의 규모에 큰 영향을 미치고 있다. 따라서 서울시 내부 인구이동의 지리적 특성인 근거리이동은 거리가 인구이동에 미치는 영

Heme-binding-mediated negative regulation of the tryptophan metabolic enzyme indoleamine 2,3-dioxygenase 1 (IDO1) by IDO2

SJR Q1Experimental & Molecular MedicineOA

Indoleamine 2,3-dioxygenases (IDOs) are tryptophan-catabolizing enzymes with immunomodulatory functions. However, the biological role of IDO2 and its relationship with IDO1 are unknown. To assess the relationship between IDO2 and IDO1, we investigated the effects of co-expression of human (h) IDO2 on hIDO1 activity. Cells co-expressing hIDO1 and hIDO2 showed reduced tryptophan metabolic activity compared with those expressing hIDO1 only. In a proteomic analysis, hIDO1-expressing cells exhibited

Sugar-sweetened beverages exacerbate high-fat diet-induced inflammatory bowel disease by altering the gut microbiome

SJR Q1The Journal of Nutritional BiochemistryOA

High-fat diets (HFDs) and frequent consumption of sugar-sweetened beverages (SSBs) are potential contributors to increasing inflammatory bowel disease (IBD) incidences. While HFDs have been implicated in mild intestinal inflammation, the role of sucrose in SSBs remains unclear. Therefore, we studied the role of SSBs in IBD pathogenesis in a mouse model and humans. C57BL6/J mice were given ad libitum access to a sucrose solution or plain water for 10 weeks, with or without an HFD. Interestingly,

지역간 인구이동의 공간적 특성 분석- 수도권을 중심으로 -
최은영

인구현상을 이해하기 위해서는 인구현상의 과정인 동시에 원인인 인구이동에 대한 분석이 필수적인데, 본 연구에서는 인구이동 흐름의 공간 특성을 파악하기 OD(Origin amd Destination)분석을 실시하였다. 1990년대 이후 주요 대도시의 인구가 감소하고 대도시 주변지역 인구가 증가함으로써 인구성장 지역의 공간적 패턴에 뚜렷한 변화가 관찰되기 시작하였다. 인구이동의 목적지와 기원지에 대한 분석을 통해 거리 조락성, 인구이동에 있어 서울의 영향력 지속, 수도권과 충청권 인구이동의 탁월성을 확인할 수 있었다. 2000년 현재 전국에서 수도권과 전입전출이 가장 활발하게 이루어지고 있는 지역은 충청권인데, 특히 공간적으로 인접한 경기도와 충청권의 인구이동이 활발한 것으로 나타나고 있다. 인구증감과 시군별 인구이동에 있어 경기도와 충청도의 일부 시군은 매우 동질적인 특성을 보이고 있어 수도권의 인구 집중이 기존 수도권의 경계를 넘어 충남북 지역으로 확대될 가능성이 높은 것으로 예상된다
