연구실 소개
김덕경 교수의 연구실은 혈관 형성 및 조직 복구를 위한 혈관 내피 줄기세포의 기능과 그 응용에 중점을 두고 있으며, 특히 심각한 말초동맥질환 등에서 혈관 생성을 유도하는 유전자 치료 전략을 개발하고 있습니다. 또한 가금류의 기생충 감염인 코쿠시디오시스에 대응하여 마늘 유도체와 커큐민 같은 천연물질이 면역 반응을 조절하고 병원성 기생충의 생존을 억제하는 메커니즘을 규명하고 있습니다. 이와 함께 ACE 유전자 다형성과 파임리놀리시스 조절 단백질 간의 연관성 등 혈관 및 혈전 형성 관련 분자 기전에 대한 기초 연구도 진행하고 있습니다.

15Endothelial progenitor cells (EPCs) act as endothelial precursors that promote new blood vessel formation and increase angiogenesis by secreting growth factors and cytokines in ischemic tissues. These facts prompt the hypothesis that EPC transplantation should accelerate the wound-repair process by facilitating neovascularization and the production of various molecules related to wound healing. In a murine dermal excisional wound model, EPC transplantation accelerated wound re-epithelialization
The effects of a compound including the secondary metabolites of garlic, propyl thiosulphinate (PTS) and propyl thiosulphinate oxide (PTSO), on the in vitro and in vivo parameters of chicken gut immunity during experimental Eimeria acervulina infection were evaluated. In in vitro assays, the compound comprised of PTSO (67 %) and PTS (33 %) dose-dependently killed invasive E. acervulina sporozoites and stimulated higher spleen cell proliferation. Broiler chickens continuously fed from hatch with
The effects of dietary supplementation with an organic extract of Curcuma longa on systemic and local immune responses to experimental Eimeria maxima and Eimeria tenella infections were evaluated in commercial broiler chickens. Dietary supplementation with C. longa enhanced coccidiosis resistance as demonstrated by increased BW gains, reduced fecal oocyst shedding, and decreased gut lesions compared with infected birds fed a nonsupplemented control diet. The chickens fed C. longa-supplemented di
This phase 1 clinical trial tested the safety of intramuscular gene transfer by using naked plasmid DNA encoding the gene for VEGF, and analyzed the potential therapeutic benefits in patients with severe peripheral arterial disease (PAD). This study was an open-labeled, dose- escalating, single-center trial on nine male patients with severe debilitating PAD who had not responded to conventional therapy. Seven had Buerger's disease and two had arteriosclerosis obliterans. Plasmid DNA (pCK) contai
The deletion (D) allele of the insertion/deletion (I/D) polymorphism of the angiotensin converting enzyme (ACE) gene is strongly associated with an increased level of circulating ACE. The ACE gene polymorphism may influence the production of angiotensin II (Ang II). It has been shown that Ang II modulates fibrinolysis, that is, Ang II increases plasminogen activator inhibitor-1 (PAI-1) mRNA and plasma PAI-1 levels in vitro and in vivo. Considered together, we tested the hypothesis that the delet
The effects of anethole on in vitro and in vivo parameters of chicken immunity during experimental avian coccidiosis were evaluated. Anethole reduced the viability of invasive Eimeria acervulina sporozoites after 2 or 4 h of treatment in vitro by 45 and 42%, respectively, and stimulated 6.0-fold greater chicken spleen cell proliferation compared with controls. Broiler chickens continuously fed from hatch with an anethole-supplemented diet and orally challenged with live E. acervulina oocysts sho
