Antigenic drift: Antigenic shift: Mechanism: Small mutations during replication lead to changes in the genes encoding antigens. Viruses swap whole sections of their genomes, leading to changes in ...

As SARS-CoV-2 has spread, it has evolved and developed mutations, causing new variants of the disease. This article provides an insight into all variations.

Researchers tracking emerging SARS-CoV-2 variants have started noticing something strange. Different subvariants seem to be accumulating the same mutations in a sign of convergent evolution but ...

The flu, for example, does not carry a proofreading enzyme, Dr. Zapata says, so it's more prone to mutations than coronaviruses are. "The flu virus can undergo what we call antigenic drift, which ...

In this article we introduce readers to antigenic essence technology, omitting some technical aspects and allowing certain liberties in the interpretation of scientific facts in favor of a ...

The study delved into the antigenic evolution of SARS-CoV-2 by utilizing cross-immunity data among different variants, establishing a cross-immunity matrix through neutralization assays, and ...

Mutational antigenic profiling quantifies the antigenic effect of all amino-acid mutations to hemagglutinin (HA). Figure from publication To do this, the authors generated libraries of mutant viruses ...

Of more relevance to this year's experience is the phenomenon of antigenic drift. Drift is a subtler process than shift and involves the accumulation of mutations within the antibody-binding sites ...

Although, like other respiratory viruses, SARS-CoV-2 is also causing seasonal spikes due to mutations, vaccines available in India aren't catered for these strains.. However, experts have said ...

As part of the host-pathogen arms race, viruses are continually evolving to evade the host immune response, be it from previous infection or immunity acquired through vaccination. Here we take a look ...
