2025
This video shows how virus-like particles, VLPs are generated by infecting insect cells with a recombinant baculovirus carrying the chikungunya virus gene cassette. The recombinant virus infects cells, leading to VLP formation, assembly, and release into the culture medium for potential use in vaccine production.

2025
This video demonstrates an assay for quantifying human norovirus virus-like particles (VLPs) binding to human intestinal bacteria. The bacterial suspensions are mixed with the VLPs and incubated to allow the formation of VLP-bacteria complexes. The complexes are then labeled with fluorophore-tagged VLP-specific antibodies, followed by flow cytometry-based visualization and quantification to identify the percentage of VLP-bound bacteria.

2025
In this video, we demonstrate an immunoprecipitation assay, called the VLP capture assay, to isolate antigen-displaying virus-like particles, or VLPs, from a sample. The antigen binds with specific antibodies bound to magnetic beads, forming an immobilized antigen-antibody complex that is later separated and stored for further analysis.

A method to analyze the solvent accessibility of the thiol group of cysteine residues of Maize rayado fino virus (MRFV)-virus-like particles (VLPs) followed by a peptide cross-linking reaction is described. The method takes advantage of the availability of several chemical groups on the surface of the VLPs that can be targets for specific reactions.

Current multiplexed diagnostics to detect Zika, chikungunya, and dengue viruses require complex sample preparation and expensive instrumentation, and are difficult to use in low resource environments. We show a diagnostic that uses isothermal amplification with target-specific strand displaceable probes to detect and differentiate these viruses with high sensitivity and specificity.
FAQs
Structural proteins provide the components that self-assemble into chikungunya VLPs. Their organization recreates the virus’s outer arrangement, so envelope antigens appear in a virus-like context rather than as isolated molecules. This presentation helps immune cells recognize relevant viral surfaces and gives researchers a platform for examining how structural organization shapes immune recognition.
Because Chikungunya VLPs lack a viral genome, they cannot support genome replication. Researchers can therefore examine recognition of chikungunya surface antigens without using a live-virus system. This distinction is important for vaccine-oriented studies that need to investigate immune protection and antibody responses while avoiding risks associated with replication-competent virus.
Envelope-antigen display places key chikungunya viral surfaces on the particle exterior, where immune cells can recognize them. That arrangement supports the generation of virus-specific antibodies and may promote antibodies with neutralizing activity. Consequently, VLP studies can focus on whether antigen recognition translates into antibody-mediated protection against features associated with chikungunya infection.
Chikungunya VLPs also support investigation of antigen presentation, the process by which immune-relevant antigen information is displayed for recognition by immune cells. Studying this process alongside antibody responses provides a broader view of protective immunity. The combined information can clarify how particle-displayed viral surfaces influence immune activation and protection-oriented responses.
In vaccine development, researchers use these particles as a noninfectious way to present chikungunya envelope antigens to the immune system. They can then examine virus-specific and potentially neutralizing antibody responses as indicators of immune recognition. These findings help assess whether the particle design supports preventive strategies without relying on a live-virus platform.
Studies can evaluate whether particle-displayed antigens elicit virus-specific antibodies, whether some antibodies show potentially neutralizing activity, and how immune cells respond to the presented viral surfaces. Researchers can also examine antigen presentation and antibody-mediated protection. Together, these outcomes connect particle design with immune function and inform safer approaches to chikungunya prevention.
Chikungunya VLPs connect structural virology with infection immunology by allowing researchers to study viral surface recognition without genome replication. Their use supports investigation of antigen presentation, antibody-mediated protection, and responses relevant to chikungunya infection. This makes them useful for comparing immune mechanisms and guiding preventive strategies that prioritize safety while preserving meaningful antigenic features.
