PDE4D and PDE3B orchestrate distinct cAMP microdomains in 3T3‐L1 adipocytes
Basal conditions: •Ins/PDE3B lowers cytoplasmic cAMP (cyt‐cAMP) without affecting plasma membrane cAMP (pm‐cAMP). •Insulin decreases lipid droplet cAMP (LD‐cAMP) independent of PDE3B. •FGF1/PDE4D modestly reduces both cyt‐ and pm‐cAMP, while PDE4D alone can modulate LD‐cAMP. ISO stimulation: •Ins/PDE3B has minimal impact on cyt‐cAMP.

Defining AV2‐1 as a novel pharmacological probe to target human and rodent TRPV2
Abstract Background and Purpose Transient receptor potential vanilloid 2 (TRPV2) is a non‐selective cation channel implicated in immune cell functions. However, progress in understanding TRPV2 has been limited by a lack of potent and selective pharmacological tools, particularly those targeting the human variant. We aimed to identify and characterise a

The extracellular matrix (ECM) is a dynamic scaffold that orchestrates tissue architecture and cellular communication. A critical but underexplored interplay between proteases and cluster of differentiation molecules (CD) governs ECM turnover and directs cell fate.

Biogenesis of TNF‐α‐insights into proteostasis and inflammation
TNF‐α biogenesis, trafficking, and signalling are tightly and reciprocally coupled to cellular proteostasis systems, including ER chaperones and endoplasmic reticulum‐associated degradation. This bidirectional crosstalk determines whether TNF‐α responses are adaptive or proteotoxic.

Electron microscopy‐based three‐dimensional subcellular imaging of plant male gametophyte
The Aquilos2 Cryo‐FIB workflows provide practical routes for cryo‐electron tomography and volume imaging in plant structural biology. ABSTRACT Understanding cellular events in three dimensions (3D) is of great importance for the annotation and illustration of biological processes in a contextual way. Imaging techniques based on electron microscopy (EM),

Abscisic acid signaling homeostasis is essential for seed storability. The molecular chaperone OsCPN10a enhances rice seed storability by forming a trimeric chaperone complex with OsCPN20‐OsHSP60‐3B that attenuates abscisic acid signaling via direct interaction with OsPYL10‐OsABIL1, thereby maintaining starch integrity and offering a promising target ...

CO2‐sensitive K+ channel traffic affects stomata and whole‐plant water use
CO2‐responsive regulation of membrane trafficking influences the density of the potassium ion (K+) channel KAT1 at the plasma membrane. CO2‐sensitive traffic, dependent on trafficking by the SNARE SYP121, impacts stomatal gas exchange and plant growth.

We identify the long‐known virulence factor VirJ as a lysyl‐phosphatidylglycerol (L‐PG) hydrolase. Like the chromosomally encoded virulence factor AcvB, it prevents excessive accumulation of L‐PG in the membrane, thereby maintaining efficient T‐DNA transfer via the Type IV secretion system (T4SS) in Agrobacterium tumefaciens.

Transcriptional profiling of the primary cell envelope stress response (CESR) of Bacillus subtilis exposed to a range of cell wall‐targeting antimicrobials, combining RNAseq and high‐resolution tiling arrays. We revealed the complexity of the CESR, the contribution of extracytoplasmic function sigma factors (ECFs) and two‐component signal transduction ...

Dehydration‐driven organization of metabolites into NaDES‐like assemblies in orthodox seeds
Summary Desiccation tolerance in plants, especially during orthodox seed dehydration, relies on compatible solute accumulation, complex molecular mechanisms, and intermolecular organizations that remain poorly understood. We combined metabolite profiling, mass spectrometry imaging, and electrospray and cold‐spray ionization mass spectrometry to ...
