Centipede venoms are complex mixtures of biochemically and pharmacologically active components such as peptides and proteins. Very few are known about their pharmacological actions. The present work reports the structural and functional characterization of two antimicrobial peptides (scolopin 1 and -2) identified from centipede venoms of Scolopendra(More)
BACKGROUND The immunoregulatory properties of mesenchymal stem cells (MSCs) have been well characterized in vitro. However, the role of MSCs in organ transplantation remains unclear. The purpose of this study was to examine the role of indoleamine 2, 3-dioxgenase (IDO)-transfected MSCs in immunoregulation both in vitro and in vivo. METHODS Wild-type (WT)(More)
In this work, we developed a sensitive and universal aptasensor for nuclear factor kappa B (NF-κB) detection based on peroxidase-like mimic coupled DNA nanoladders for signal amplification. The dsDNA formed by capture DNA S1 and NF-κB binding aptamer (NBA) was firstly assembled on electrode surface. The presence of target NF-κB then led to the leave of NBA(More)
The amplified sensitive detection of protein is essential to biomedical research as well as clinical diagnosis. Here, we developed an ultrasensitive mediator-free triple-enzyme cascade electrocatalytic aptasensor for thrombin detection on the basis of exonuclease-assisted target recycling and hybridization chain reaction (HCR) amplification strategy.
