Wolbachia infections in native and introduced populations of fire ants (Solenopsis spp.) [PDF]

, 2000
Wolbachia are cytoplasmically inherited bacteria that induce a variety of effects with fitness consequences on host arthropods, including cytoplasmic incompatibility, parthenogenesis, male-killing and feminization.

PD‐1 Inhibits CD4+ TRM‐Mediated cDC1 Mobilization via Suppressing JAML in Human NSCLC

Advanced Science, EarlyView.
CD4+ tissue‐resident memory T cells (TRMs) in non‐small cell lung cancer recruit conventional type 1 dendritic cells via XCL1‐XCR1 signaling, orchestrating antitumor immunity. The costimulatory molecule JAML is essential for this process. PD‐1 blockade restores JAML expression and cDC1 mobilization, while JAML agonists synergize with anti‐PD‐1 therapy,

Wolbachia divergence and the evolution of cytoplasmic incompatibility in Culex pipiens.

PLoS ONE, 2014
Many insect species harbor Wolbachia bacteria that induce cytoplasmic incompatibility (CI), i.e. embryonic lethality in crosses between infected males and uninfected females, or between males and females carrying incompatible Wolbachia strains.

On maximal chain subgraphs and covers of bipartite graphs [PDF]

, 2016
In this paper, we address three related problems. One is the enumeration of all the maximal edge induced chain subgraphs of a bipartite graph, for which we provide a polynomial delay algorithm.

Evolution-guided mutagenesis of the cytoplasmic incompatibility proteins: Identifying CifA’s complex functional repertoire and new essential regions in CifB

bioRxiv, 2020
Wolbachia are the world’s most common, maternally-inherited, arthropod endosymbionts. Their worldwide distribution is due in part to a selfish drive system termed cytoplasmic incompatibility (CI) that confers a relative fitness advantage to females that ...

Ribosome Homeostasis Regulated by SETD2 Preserves Intestinal Epithelial Barrier

Advanced Science, EarlyView.
SETD2 ablation causes dysregulation and recruitment defects of ribosome biogenesis factors, resulting in translational disorders of barrier maintenance genes, thereby compromising the intestinal barrier. These findings unveil a previously unappreciated role of ribosome biogenesis and translational regulation in preserving the intestinal epithelial ...

Structured and unstructured continuous models for Wolbachia infections [PDF]

, 2009
We introduce and investigate a series of models for an infection of a diplodiploid host species by the bacterial endosymbiont Wolbachia. The continuous models are characterized by partial vertical transmission, cytoplasmic incompatibility and fitness ...

Melanic mutation causes a fitness decline in bean beetles infected by Wolbachia [PDF]

, 2017
Wolbachia cannot live outside a host, which is thought to be the reason for host‐Wolbachia coevolution toward benign parasitism, especially because the fitness of Wolbachia is traded against its host\u27s fitness.

Wolbachia and cytoplasmic imcompatibility in mosquitoes

Insect Biochemistry and Molecular Biology, 2004
Wolbachia are maternally inherited bacteria that induce cytoplasmic incompatibility in mosquitoes, and are able to use these patterns of sterility to spread themselves through populations. For this reason they have been proposed as a gene drive system for mosquito genetic replacement, as well as for the reduction of population size or for modulating ...

ZNRD2 Mediated Nucleoprotein Aggregation Impairs Respiratory Syncytial Virus Replication

Advanced Science, EarlyView.
During RSV infection, nucleoprotein (N) forms RNA‐bound oligomers. The host protein ZNRD2 binds to these oligomers, promoting their transition into insoluble aggregates. These aggregates simultaneously sequester functional N to restrict viral production and disrupt chaperonin assembly quality control by interfering with ZNRD2's role as an adaptor ...
