연구실 소개
조윤정 교수의 연구실은 대사질환, 특히 당뇨병과 예방단계의 대사증후군에서의 인슐린 감수성 향상 및 염증 반응 조절을 중심으로 한 기전 연구를 수행하고 있습니다. 특히 타이아졸리딘디온 파생제의 대사적 효과와 면역세포 반응, 바이러스 감염에 따른 면역 반응의 다양성 및 규제 메커니즘을 다각도로 분석하고 있습니다. 최근에는 코로나19 백신 접종 후 유전자형, 연령, 성별에 따른 체액성 및 세포성 면역 반응의 상관관계를 규명하는 연구도 진행 중입니다. 이는 만성 염증성 질환 및 감염성 질환의 새로운 치료 전략 개발에 기여하고자 하는 목표를 가집니다.

However, it is not well known whether these beneficial effects occur in subjects without diabetes, such as prediabetes or the non-diabetic metabolic syndrome (MetS). The present study was therefore designed to evaluate the effectiveness of the insulin-sensitizing agent rosiglitazone on circulating adipocytokine levels and brachial-ankle
AIMS/INTRODUCTION: To assess the time to initiation of insulin therapy, and concurrently investigate both patient- and physician-related factors associated with delaying insulin therapy in Korean patients with type 2 diabetes uncontrolled by oral hypoglycemic agents (OHAs). MATERIALS AND METHODS: This prospective, observational disease registry study was carried out across 69 centers in Korea. Type 2 diabetes patients who had received two or more OHAs within the past 5 years, had a glycated hemo
CD8(+)-T-cell (T(CD8+)) responses to infectious viruses are characterized by an immunodominance hierarchy in which the majority of T(CD8+) respond to one or a few immunodominant determinants, with a minority of T(CD8+) responding to a number of subdominant determinants. It is now well established that exogenous antigens are capable of inducing T(CD8+) to such immunodominant determinants, but the diversity of the response and the nature of the immunodominance hierarchy have not been examined. We
Respiratory syncytial virus (RSV) is the leading cause of lower respiratory tract infections and hospitalization in infants and young children. Here, we analyzed the genetic diversity of RSV using partial G gene sequences in 84 RSV-A and 78 RSV- B positive samples collected in Seoul, South Korea, for 10 consecutive years, from 2010 to 2019. Our phylogenetic analysis revealed that RSV-A strains were classified into either the ON1 (80.9%) or NA1 (19.0%) genotypes. On the other hand, RSV-B strains
There have been few studies that comprehensively evaluated factors affecting immune responses and the correlation between humoral and cellular immune responses after vector, mix-and-match, and mRNA vaccines against SARS-CoV-2. Therefore, we analyzed the effects of age, sex, and the different vaccine regimens on the immune responses to vaccination against SARS-CoV-2. The correlation between humoral and cellular immune responses and the cutoffs were derived for RBD antibodies and neutralizing anti
Quercetin significantly inhibits iNOS-derived NO production in murine macrophages activated by P. intermedia LPS via anti-inflammatory HO-1 induction and inhibition of the nuclear factor-κB and STAT1 signaling pathways. Our study suggests that quercetin may contribute to the modulation of host-destructive responses mediated by NO and appears to have potential as a novel therapeutic agent for treating inflammatory periodontal disease.
BACKGROUND: The seroprevalence rate of human T-lymphotropic virus I and II (HTLV-I/II) in Korean blood donors has been known as 0.004%, and HTLV-I/II Ab screening test has been performed since 2008 in Korea. Korea Ministry of Food and Drug Safety (MFDS) approved two chemiluminescent microparticle immunoassays (CMIA) for testing HTLV-I/II antibody, ABBOTT PRISM HTLV-I/HTLV-II and ARCHITECT rHTLV-I/II. A multicenter performance evaluation study in Europe and Japan was carried out with the new elec
Background: Dental hygienists are at risk of acquiring infections through exposure to infectious agents. This study explores the frequency of exposure to infectious agents and infection control practices among dental hygienists. Methods: We undertook a cross-sectional survey to examine the exposure to infectious agents and infection control practices among dental hygienists through questionnaire. Data were obtained from 124 dental hygienists attending educational conferences. A multiple logistic
The new allele, B*55:81, differs from B*55:02:01:02 by 2 nucleotide substitutions in codon 116 (TTA → TAC).
The new allele B*54:39 showed one nucleotide difference from B*54:01:01 in codon 10 (ACC->AGC).
Endometriosis is a disorder in which endometrial glandular tissue and stroma are found outside the uterus; it involves the colorectum in about 5 % of cases [1] [2]. It can occasionally be difficult to differentiate between colonic endometriosis, usually manifest as strictures or external compression, and colon cancer or colitis [3]. In particular, the rare polypoid endometriosis is hardly distinguishable from colonic neoplasm [4]. More careful inspection and diagnostic methods are therefore requ
