  1. [Correspondence] #Virological and #antigenic characteristics of #SARS-CoV-2 #variants #LF.7.2.1, #NP.1, and #LP.8.1 thelancet.com/journals/laninf/

    ... several sublineages of #JN.1 are increasingly out-competing XEC and KP.3.1.1, exhibiting superior growth advantages; for example, LF.7.2.1, MC.10.1, NP.1, and, most importantly, LP.8.1 (figure A, B).

  3. The #antigenic #landscape of #N1 #neuraminidase in #human #influenza A virus strains isolated between 2009 and 2020, BioRxIV, biorxiv.org/content/10.1101/20

    The resulting neuraminidase inhibition pattern revealed two antigenic groups that circulated in this period. A machine learning method identified K432E and I321V as key determinants of N1 neuraminidase antigenicity.

  5. Evolving #antibody #response to #SARS-CoV-2 #antigenic #shift from #XBB to #JN1

    Source: Nature, AbstractThe continuous evolution of SARS-CoV-2, particularly the emergence of BA.2.86/JN.1 lineage replacing XBB, necessitates re-evaluation of vaccine compositions 1–3. Here, we provide a comprehensive analysis of the humoral immune response to XBB and JN.1 human exposure. We demonstrate the antigenic distinctiveness of XBB and JN.1 lineages in SARS-CoV-2-naive individuals,…

  7. #Human and #hamster #sera correlate well in identifying #antigenic #drift among #SARS-CoV-2 #variants, including #JN1

    Source: Journal of Virology, ABSTRACTAntigenic assessments of SARS-CoV-2 variants inform decisions to update COVID-19 vaccines. Primary infection sera are often used for assessments, but such sera are rare due to population immunity from SARS-CoV-2 infections and COVID-19 vaccinations. Here, we show that neutralization titers and breadth of matched…

    Source: Journal of Viroloyg, ABSTRACTNeuraminidase (NA)-specific antibodies have been associated with protection against influenza and thus NA is considered a promising target for next-generation vaccines against influenza A (IAV) and B viruses (IBV). NA inhibition (NI) by antibodies is typically assessed using an enzyme-linked…
