Antiviral efficacy of the SARS-CoV-2 XBB breakthrough infection sera against Omicron subvariants including EG.5

This study evaluates the antiviral efficacy of XBB breakthrough infection sera against EG.5.1 and other Omicron subvariants, finding comparable neutralization titers and suggesting immune evasion is not the main driver of EG.5.1's spread.

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.

Virological characteristics of the novel SARS-CoV-2 Omicron variants including BA.2.12.1, BA.4 and BA.5

This study analyzes the virological characteristics of SARS-CoV-2 Omicron variants BA.2.12.1, BA.4, and BA.5, finding they have higher reproduction numbers, reduced neutralization by prior immunity, increased replication in lung cells, and greater pathogenicity in hamsters compared to BA.2.

SARS-CoV-2 spike S375F mutation characterizes the Omicron BA.1 variant

This study identifies the S375F mutation in the Omicron spike protein as responsible for its reduced cleavage efficiency, fusogenicity, and rapid spread.

Virological characteristics of SARS-CoV-2 BA.2 variant

This study compares the virological characteristics of SARS-CoV-2 BA.2 and BA.1 variants, finding BA.2 has higher transmissibility, different antigenicity, greater replicative capacity, and higher pathogenicity in hamsters.

A widely-distributed HIV-1 provirus elimination assay to evaluate latency-reversing agents in vitro

The paper develops a new assay to evaluate latency-reversing agents by eliminating HIV-1 proviruses in a long-term cell culture system.

SARS-CoV-2 spike P681R mutation, a hallmark of the Delta variant, enhances viral fusogenicity and pathogenicity

This study shows the P681R mutation in the SARS-CoV-2 spike protein enhances fusogenicity and pathogenicity in the Delta variant compared to the prototypic virus.
