A new study published in Nature Microbiology has uncovered significant genetic and antigenic diversity among H9N2 avian influenza ... High prevalence of mutations such as HA-L226, NP-N52, ...

Between 2021 and 2023, 99.46% of H9N2 isolates carried the HA-L226 mutation linked to human receptor binding; 96.17% contained the NP-N52 mutation associated with resistance to the human MxA ...

Prior COVID-19 vaccination did not stop the immune system from mounting a protective response to the delta and omicron strains, though new mutation-specific antibody production dipped slightly ...

A study of more than 3,000 genomes has traced a gene mutation that confers HIV resistance to a person who lived near the Black Sea around 7000 B.C.

Specialised effector response and cancer-immune interactions. Neoantigens trigger responses from the adaptive immune system: each antigenic mutation i calls a unique, specialised effector population E ...

Antigenic drift allows the virus to escape immune recognition in people who have been vaccinated or had a previous ... Mutations in HA are considered to cause the majority of antigenic ...

Vulnerability to different COVID-19 mutations depends on previous infections and vaccination, study suggests ... Mapping SARS-CoV-2 antigenic relationships and serological responses.

Vulnerability to different COVID-19 mutations depends on previous infections and ... Samuel H. Wilks et al, Mapping SARS-CoV-2 antigenic relationships and serological responses, Science ...

The monthly prevalence of mutations and SARS-CoV-2 test positivity rates were assessed across three-month intervals to determine mutations associated with sudden increases in COVID-19 cases.

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 Beta and Gamma variants, which have K417N/T mutation in addition to the E484K mutation, clustered together on the antigenic map. Conclusions.

Intriguingly, mutations in antigenic proteins were enriched over non-antigenic proteins for some subclades. This finding suggested that in these cases the human immune response could be a robust ...
