The persistent emergence and re-emergence of infectious diseases highlights a critical need for rapid, adaptable vaccine development technologies. Conventional vaccine development pipelines are frequently constrained by long timelines and limited flexibility, underscoring the importance of modular platforms that can accommodate diverse antigens with minimal reconfiguration.
This proof-of-concept study aims to establish a modular, plug-and-play vaccine platform based on virus-like particles (VLPs) to rapidly generate protein-based vaccine candidates. The proposed platform is designed to be both flexible and scalable, facilitating the incorporation of a broad spectrum of antigens targeting various infectious diseases.
The platform employs a VLP derived from Porcine Circovirus type 2d (PCV2d) as a structural scaffold. Antigens are engineered to associate with the VLP surface via designed coiled-coil peptide interactions, thereby enabling modular assembly. VLPs are produced using a baculovirus expression system in insect cells, while antigens can be expressed in systems optimised for their specific biochemical properties.
Initial characterisation of antigen–VLP interactions is conducted using green fluorescent protein (GFP) and FITC fused to coiled-coil domains, serving as a model system to assess binding efficiency and antigen presentation. Optimisation of protein expression is ongoing, supported by analytical techniques such as SDS-PAGE, Western blotting, and size-exclusion chromatography (SEC-HPLC) to evaluate yield, purity, and structural integrity.
The first set of protein constructs for both VLPs and model GFP antigens has been expressed and purified. In the case of TGX003, expression and purification were successful, and the desired protein characteristics were achieved. This VLP was further characterised with SEC-HPLC and AFM measurements. Further validation will be conducted through the development and preclinical testing of a VLP-based vaccine targeting a relevant human infectious disease.
This research was supported by the 2024-2.1.2-EKÖP-KDP New National Excellence program of the Ministry for Culture and Innovation from the source of the National Research, Development and Innovation Fund.
