Summary
Scientists created EVE-Vax, a computational tool to design future viral antigens. This method predicts immune escape, enabling early evaluation of vaccines and therapeutics against emerging SARS-CoV-2 variants.
Area of Science:
- Virology
- Immunology
- Computational Biology
Background:
- Recurrent viral infections necessitate adaptable vaccines and therapeutics.
- Current evaluation methods for interventions are limited to past or circulating variants, not future strains.
- Assessing future immune escape potential is crucial for pandemic preparedness.
Purpose of the Study:
- To develop a computational method (EVE-Vax) for designing antigens that predict future viral immune escape.
- To create synthetic SARS-CoV-2 spike proteins that foreshadow immune escape.
- To enable early evaluation of vaccine and therapeutic efficacy against emerging viral variants.
Main Methods:
- Developed EVE-Vax, a computational approach for antigen design.
- Designed 83 SARS-CoV-2 spike proteins.
- Assessed cell transduction, neutralization resistance, and antibody escape potential of designed spikes.
- Evaluated booster responses in non-human primates.
Main Results:
- Designed spike proteins exhibited neutralization resistance comparable to variants emerging up to 12 months later.
- Designed spikes accurately predicted antibody escape from bivalent booster sera seen in later variants.
- Nanoparticle-based boosters elicited greater neutralization breadth than mRNA-based boosters in non-human primates.
Conclusions:
- EVE-Vax can design synthetic antigens that predict future immune escape.
- The designed constructs serve as tools for early evaluation of vaccine and therapeutic candidates.
- This approach maps the immune landscape to prepare for emerging viral threats.

00:36Viral Mutations
32.2K
A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...

02:28Leaky Scanning
5.1K
During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA. Marilyn Kozak discovered that the sequence RCCAUGG (where R...

01:29Immune Response Against Viral Pathogens
765
The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...

02:26Conservation of Protein Domains Over Different Proteins
10.8K
Protein domains are small structurally independent units that are part of a single amino acid chain. Although these domains are often structurally independent, they may rely on synergistic effects to perform their functions as part of a larger protein. Protein domains may be conserved within the same organism, as well as across different organisms.
A limited set of protein domains often duplicate and recombine during evolution. These domains can be organized in different combinations to...
