Immature stages of Nisoniades macarius (Hesperiidae: Pyrginae: Carcharodini): biology, morphology and behavior

Iheringia: Série Zoologia, 2021
The biology, morphology and behavior of the immature stages of Nisoniades macarius (Herrich-Schäffer, 1870) are herein described from specimens collected in an anthropized area of Caatinga biome. The larva of N. macarius passes through six larval instars

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Bacterial exopolysaccharides mediate activation of flavin-containing monooxygenase 2 to extend lifespan in Caenorhabditis elegans

Cell Communication and Signaling
The gut microbiota plays a pivotal role in modulating host physiology and longevity through the production of microbial-derived molecules. Among these, bacterial exopolysaccharides (EPS) represent a structurally diverse group of surface polysaccharides ...

MicroRNAs from the parasitic plant Cuscuta campestris target host messenger RNAs

Nature, 2017
Dodders (Cuscuta spp.) are obligate parasitic plants that obtain water and nutrients from the stems of host plants via specialized feeding structures called haustoria.

Structural insights into lacto‐N‐biose I recognition by a family 32 carbohydrate‐binding module from Bifidobacterium bifidum

FEBS Letters, EarlyView.
Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.

Peptide‐based ligand antagonists block a Vibrio cholerae adhesin

FEBS Letters, EarlyView.
The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...
