#Virological characteristics of the #SarsCoV2 #KP3, #LB1 and #KP23 #variants, BioRxIV, https://www.biorxiv.org/content/10.1101/2024.06.05.597664v1?rss=1
Our results suggest that S #substitutions convergently acquired in #JN1 #subvariants contribute to immune evasion, & increase their Re when compared to parental JN.1. LB.1 & KP.2.3 exhibited higher pseudovirus #infectivity & more immune resistance than KP.2. Data suggest that S:S31del is critical to exhibit +infectivity, +immune evasion, & potentially contributes to increased Re.

#Virological characteristics of the #SARS-CoV-2 #Omicron #XBB15 #variant, Nat Commun.: https://www.nature.com/articles/s41467-024-45274-3
-- We provide intrinsic pathogenicity of XBB.1 & XBB.1.5 in hamsters. ...we find that #ORF8 nonsense mutation of XBB.1.5 resulted in impairment of #MHC suppression. In vivo experiments using recombinant viruses reveal that XBB.1.5 mutations are involved with reduced virulence of XBB.1.5... our study identifies 2 viral functions defined difference between XBB.1 & XBB.1.5.
