研究室紹介
Professor Duck-kyung Kim's research lab focuses on translational biomedical and veterinary immunology, with a strong emphasis on angiogenesis, wound healing, and host defense mechanisms against infectious diseases. The lab investigates the therapeutic potential of natural compounds—such as garlic metabolites, curcumin, and anethole—in enhancing immune responses and improving outcomes in coccidiosis and peripheral arterial disease. Key research directions include endothelial progenitor cell therapy, gene therapy using VEGF plasmid DNA, and the role of genetic polymorphisms (e.g., ACE I/D) in fibrinolysis and disease susceptibility. The work bridges preclinical models with clinical applications, particularly in regenerative medicine and infectious disease control in both humans and poultry.

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
