SARS‐CoV‐2 Variants and Immune Evasion: Mapping the Future of Vaccine Design

Reviews in Medical Virology, Volume 36, Issue 3, May 2026.
ABSTRACT The evolutionary trajectory of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS‐CoV‐2) has progressed through several distinct phases since its zoonotic emergence, transitioning from initial human adaptation to an era of rapid antigenic drift and complex immune evasion. As of early 2026, the global landscape is dominated by highly evolved

Legionella metaeffector MavL reverses ubiquitin ADP-ribosylation via a conserved arginine-specific macrodomain

Nature Communications
ADP-ribosylation is a reversible post-translational modification involved in various cellular activities. Removal of ADP-ribosylation requires (ADP-ribosyl)hydrolases, with macrodomain enzymes being a major family in this category.

Differential management of the replication terminus regions of the two Vibrio cholerae chromosomes during cell division. [PDF]

PLoS Genetics, 2014
The replication terminus region (Ter) of the unique chromosome of most bacteria locates at mid-cell at the time of cell division. In several species, this localization participates in the necessary coordination between chromosome segregation and cell ...

CACHE Challenge #3: Targeting the Nsp3 Macrodomain of SARS-CoV-2. [PDF]

J Chem Inf Model
The third Critical Assessment of Computational Hit-finding Experiments (CACHE) challenged computational teams to identify chemically novel ligands targeting the macrodomain 1 of SARS-CoV-2 Nsp3, a promising coronavirus drug target. Twenty-three groups deployed diverse design strategies to collectively select 1739 ligand candidates.

Multiorgan Molecular Landscape of Severe COVID‐19 Revealed by Consensus Gene Signatures and RAB8B Targeting

Journal of Medical Virology, Volume 98, Issue 4, April 2026.
ABSTRACT Severe COVID‐19 involves hyperinflammation and multiorgan pathology, but consistent gene signatures remain elusive. We aimed to identify consensus transcriptomic signatures and molecular mechanisms in severe COVID‐19. We performed an integrative analysis of 39 studies spanning 11 tissue types, 1551 bulk RNA‐seq samples, and over 2 million ...

Recent advances in noncanonical inhibition mechanisms of anti‐CRISPR proteins

mLife, Volume 5, Issue 2, Page 133-147, April 2026.
Abstract The CRISPR‐Cas system constitutes an adaptive immune mechanism in prokaryotes that defends against mobile genetic elements. Within the perpetual co‐evolutionary arms race between bacteria and their viral predators, bacteriophages encode anti‐CRISPR (Acr) proteins that use sophisticated molecular strategies to sabotage CRISPR‐Cas function ...

Gene clusters reflecting macrodomain structure respond to nucleoid perturbations [PDF]

Molecular BioSystems, 2010
Abstract Focusing on the DNA-bridging nucleoidproteins Fis and H-NS, and integrating several independent experimental and bioinformatic data sources, we investigate the links between chromosomal spatial organization and global transcriptional regulation.

Prokaryotic defense systems: Diversity and evolutionary adaptation

mLife, Volume 5, Issue 1, Page 3-16, February 2026.
Abstract Bacteriophages and archaeal viruses are the most abundant biological entities on Earth. Through a long‐standing co‐evolutionary arms race, they have driven the emergence of a diverse repertoire of prokaryotic defense systems. This review summarizes these systems, highlighting their diverse antiviral mechanisms across distinct stages of viral ...

The macrodomain family: Rethinking an ancient domain from evolutionary perspectives [PDF]

Chinese Science Bulletin, 2013
The reasons why certain domains evolve much slower than others is unclear. The notion that functionally more important genes evolve more slowly than less important genes is one of the few commonly believed principles of molecular evolution. The macro-domain (also known as the X domain) is an ancient, slowly evolving and highly conserved structural ...
