Abstract
Human noroviruses (HuNoVs) are the major cause to acute nonbacterial gastroenteritis outbreaks. The receptors of HuNoVs are difficult to identify because HuNoVs cannot be easily cultivated in vitro and they lack effective animal models. To develop an effective method for mining functional viral receptors, engineering Escherichia coli were constructed to display P domain of capsid protein of HuNoVs (GI.1 or GII.4) on the cell surface, using the N-terminal of the ice nucleation protein (InaQN). In this study, membrane protein-porcine gastric mucin binding ELISA methods were employed to confirm the surface display efficiency. The receptor binding capacity of InaQN-P (GI.1 or GII.4) fusion proteins on the bacterial surface was evaluated through whole-cell fluorescence immunoassay with saliva-based histo-blood group antigens. Results revealed remarkable characteristic of antigenicity and receptor binding properties. Therefore, this bacterial surface display system should be considered as a candidate to mine and investigate HuNoV receptors in vivo or in vitro.
