The complement system's distinguishing feature is its cell-specific surface ligands. However, the limited scalability and complexity of incorporating surface-customizable ligands into membrane-bound cell-like microassemblages have hindered their widespread adoption in synthetic biology and bioengineering. Here, we present a method for the batch construction of polysaccharide-based microcapsules (polysaccharidosomes, P-somes) with intrinsic functional host membranes capable of [...]

Background/Objectives: Potency is a critical quality attribute for vaccine development as well as clinical drug product (DP) lot release and stability testing. Animal studies have the potential to offer conclusive insights about the potency of vaccines by demonstrating technical relevance with respect to the hypothesized vaccine mode of action. However, animal studies are expensive, time-consuming, [...]

Dynamic therapy utilizes reactive oxygen species (ROS) to antibacterial and enhance the innate immune system to treat bacterial infections. If ROS levels are too low, the elimination of pathogens and the enhancement of innate immunity cannot be achieved. However, excess accumulation of ROS may impact intracellular glutathione (GSH) levels, hindering T cell maturation and the [...]

Duck Tembusu virus (DTMUV), an emerging avian pathogenic flavivirus, causes severe neurological disorders and acute egg drop syndrome in ducks. Currently, several clusters of DTMUV exhibiting significant antigenic variation are circulating in Asia with distinct geographical distributions. Therefore, developing vaccines based on virus clusters specific to regions is essential. To generate an effective inactivated vaccine, [...]

Immunogenicity knowledge and the analytical capabilities to characterize molecules have evolved within the last decade. This creates opportunities in Biosimilar development by applying new strategies to demonstrate similarity between a proposed Biosimilar to its Reference.Within Immunogenicity Risk Assessment for Biosimilars, in silico and in vitro immunogenicity assessment tools are being evaluated for their utility in [...]
