The principal objective of this study was to evaluate the feasibility of Hepatitis B virus (HBV) vaccine switch program after 1-year Hepatitis B immunoglobulin (HBIG) for the prevention of de novo HBV (DNHBV) infection in pediatric recipients of hepatitis B core antibody (anti-HBc)-positive grafts. In this study, we enrolled pediatric recipients (n = 14),(More)
Since avian-origin H3N2 canine influenza virus (CIV) was first identified in South Korea in 2008, the novel influenza virus has been reported in several countries in Asia. Reverse zoonotic transmission of pandemic H1N1 (2009) influenza virus (pH1N1) has been observed in a broad range of animal species. Viral dominance and characterization of the(More)
IL-23 is a heterodimeric cytokine consisting of p19 and the p40 subunit of IL-12. IL-23 has been shown to possess IL-12-like biological activities, but is different in its capacity to stimulate memory T cells in vitro. In this study, we investigated whether IL-23 could influence envelope protein 2 (E2)-specific cell-mediated immunity induced by immunization(More)
IL-12p40 homodimer is a natural antagonist of IL-12 and IL-23, which are potent pro-inflammatory cytokines required for Th1 and Th17 immune responses, respectively. It has been reported that Th17 response is involved in inflammatory bowel disease (IBD), a chronic disorder of the digestive system with steadily increasing incidence. Here, we investigated the(More)
Atopic dermatitis (AD) is a chronic inflammatory skin disease that is closely related to dysregulation of the T helper type 1 and 2 (Th1)/Th2 balance. A previous study showed that high molecular mass poly-γ-glutamate (γ-PGA) isolated from Bacillus subtilis sp. Chungkookjang induces the production of IL-12 from dendritic cells (DCs). Here, we investigated(More)
BACKGROUND Obesity, a risk factor for increased severity of diverse diseases, is believed to have negative impact on vaccine efficacy. Recently, mortality has emerged as an outcome of pandemic influenza A virus subtype H1N1, necessitating development of effective vaccine strategies. Here we investigated effects of diet-induced obesity on vaccine-induced(More)
Pancreatic cancer is the fourth most common cause of cancer-related mortality. In the present study, we employed 2 types of therapeutic stem cells expressing cytosine deaminase (CD) with or without human interferon-β (IFN‑β), HB1.F3.CD and HB1.F3.CD.IFN-β cells, respectively, to selectively treat pancreatic cancer. The CD gene converts the non-toxic(More)
A scan matching technique is a key technique to implement Cooperative-SLAM (C-SLAM). Although a variety of scan matching techniques have been developed, each of them has both merits and faults. This paper compares and analyzes three well-known scan matching techniques which are ICP (Iterative Closest Points), HSM (Hough Scan Matching), and PSM (Polar Scan(More)
Influenza is an acute respiratory disease and a major health problem worldwide. Since mucosal immunity plays a critical role in protection against influenza virus infection, mucosal immunization is considered a promising vaccination route. However, except for live-attenuated vaccines, there are no effective killed or recombinant mucosal influenza vaccines(More)
IL-12p40 is a natural antagonist which inhibits IL-12- and IL-23-mediated biological activity by blocking the binding of IL-12/23 to their receptors. Recently, IL-12p40 was also shown to have immune-enhancing activity through the activation of macrophages or dendritic cells. In this study, we investigated the effects of IL-12p40 as a genetic adjuvant on(More)
