Generation of a porcine cell line stably expressing pig TMPRSS2 for efficient isolation of viruses from pigs with respiratory diseases

Virological characteristics of the SARS-CoV-2 XBB.1.5 variant

The paper analyzes the virological characteristics of the SARS-CoV-2 XBB.1.5 variant, showing reduced pathogenicity and impaired MHC expression due to mutations in ORF8 and S.

Generation of porcine PK-15 cells lacking the Ifnar1 gene to optimize the efficiency of viral isolation

This study generates a PK-15 cell line lacking the Ifnar1 gene to improve viral isolation efficiency from contaminated clinical samples.

Conserved use of the sodium/bile acid cotransporter (NTCP) as an entry receptor by hepatitis B virus and domestic cat hepadnavirus

This study identifies NTCP as the entry receptor for domestic cat hepadnavirus, showing similarity to HBV and suggesting potential for cross-species transmission.

Virological characteristics of the SARS-CoV-2 XBB variant derived from recombination of two Omicron subvariants

This study identifies XBB as a SARS-CoV-2 variant resulting from recombination of BA.2 subvariants, showing increased resistance to neutralizing antibodies and enhanced fusogenicity compared to BA.2.75.

Convergent evolution of the SARS-CoV-2 Omicron subvariants leading to the emergence of BQ.1.1 variant

The paper investigates convergent evolution in SARS-CoV-2 Omicron subvariants, identifying five critical spike protein substitutions in BQ.1.1 that enhance viral fitness and antibody resistance.

Virological characteristics of the SARS-CoV-2 Omicron BA.2.75

This study investigates the virological characteristics of SARS-CoV-2 Omicron BA.2.75, finding it has higher transmissibility and pathogenicity compared to BA.2 and BA.5, but similar sensitivity to antiviral drugs.
