Summary
Researchers created a database of SARS-CoV-2 variants that escape antibody neutralization. This resource aids in understanding viral evolution and immune response to COVID-19 vaccines and treatments.
Area of Science:
- Virology
- Genomics
- Immunology
Background:
- Global genomic surveillance of SARS-CoV-2 is crucial for understanding COVID-19 epidemiology and evolution.
- Genetic variants, particularly in spike proteins, can impact viral transmission and immune evasion.
- Antibody neutralization escape is a significant concern for vaccine and therapeutic efficacy.
Purpose of the Study:
- To compile a comprehensive database of SARS-CoV-2 variants with potential antibody escape mechanisms.
- To provide a curated repository of variants, antibodies, and clinical data for research.
Main Methods:
- Manual curation of variants from scientific literature.
- Systematic collation of data on SARS-CoV-2 genetic variants and their interactions with neutralizing antibodies.
- Inclusion of data from patient convalescent plasma and vaccine breakthrough events.
Main Results:
- The database contains 5258 variants, including 2068 unique variants.
- These variants have been tested against 230 different antibodies.
- The resource documents instances of immune escape, including vaccine breakthrough events.
Conclusions:
- The developed database offers a valuable resource for researchers studying SARS-CoV-2 immune escape.
- It facilitates a deeper understanding of the mechanisms underlying immune response to SARS-CoV-2.
- This resource can inform the development of future vaccines and antibody-based therapies.

16.8K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

1.1K
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...

Simple proteins and protein complexes contain only amino acids. In contrast, many other proteins, called conjugated proteins, covalently bond with non-protein moieties.
Nucleoproteins are protein complexes that contain nucleic acids, categorized as deoxyribonucleoproteins (DNPs) or ribonucleoproteins (RNPs) respectively. The nucleosome is a typical example of a DNP where nuclear DNA is associated with histone proteins. The major antigen for the Covid-19 virus SARS-CoV is an RNP that is critical...

00:36Viral Mutations
35.0K
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...

Antigen receptors are essential components of the immune system crucial in defending the body against foreign invaders. These receptors are present on the surface of B and T cells, enabling them to recognize antigens and mount an appropriate immune response.
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...

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...
