Stress‐Induced Switch in Small Extracellular Vesicle Secretion: From Constitutive ‘Torn Bag Mechanism’ to Exocytosis

Journal of Extracellular Vesicles, Volume 15, Issue 8, August 2026.
Stress‐induced switch. Under stress conditions, small extracellular vesicle release shifts from the constitutive ‘torn bag mechanism’ to exocytosis of multivesicular endosomes. https://BioRender.com/xn1pa1e. ABSTRACT The biogenesis of small extracellular vesicles (sEVs) is only partially understood.

S-Nitrosylation Inhibits Pannexin 1 Channel Function [PDF]

Journal of Biological Chemistry, 2012
S-nitrosylation is a post-translational modification on cysteine(s) that can regulate protein function, and pannexin 1 (Panx1) channels are present in the vasculature, a tissue rich in nitric oxide (NO) species. Therefore, we investigated whether Panx1 can be S-nitrosylated and whether this modification can affect channel activity.

An unattended image‐processing pipeline for on‐the‐fly quality assessment and 3D exploration in cryo‐EM

Acta Crystallographica Section D, Volume 82, Issue 8, Page 915-939, August 2026.
We present a fully automated, unattended cryo‐EM pipeline that serves as an on‐the‐fly diagnostic tool, enabling rapid data‐quality assessment and informed decision‐making to maximize data‐collection efficiency.Single‐particle analysis (SPA) by cryogenic electron microscopy (cryo‐EM) has become a cornerstone of structural biology; yet, the workflow ...

Astrocyte Mechanobiology: Linking Biomechanical Forces to Biochemical Signaling in the Central Nervous System

Glia, Volume 74, Issue 7, July 2026.
Astrocytes are key sensors and transducers of biomechanical stimuli within the central nervous system. Astrocyte development is highly dependent on mechanical stimuli such as surrounding tissue stiffness and biomechanical strain. Mechanosensory pathways including integrins, connexins and pannexins, and mechanosensitive channels regulate astrocyte ...

The Multifaceted Role of Pyroptosis: Molecular Mechanisms, Crosstalk with Other Cell Death Pathways, and Therapeutic Implications

MedComm, Volume 7, Issue 7, July 2026.
Pyroptosis maintains immune homeostasis by eliminating damaged or infected cells, but its dysregulation promotes inflammation and cancer progression. The diagram illustrates key activation pathways, links with other programmed cell deaths, and cancer‐specific effects, enhancing its dual protective and pathogenic roles.

The emerging Pannexin 1 signalome: a new nexus revealed?

Frontiers in Cellular Neuroscience, 2014
Pannexins (Panxs) are a family of single-membrane, large-pore ion and metabolite permeable channels. Of the three Panx proteins, Panx1 has been most extensively studied, and has recently emerged as an exciting, clinically relevant target in many ...

When can AlphaFold predict the oligomeric states of proteins?

Protein Science, Volume 35, Issue 7, July 2026.
Abstract Homooligomerisation is a prevalent and important process that many proteins undergo to form the quaternary structures required for biological function. However, determining oligomeric states and structures experimentally remains technically challenging and time‐consuming for many proteins.

Pannexin-1 in silico modeling towards physiological and pathological functioning

, 2020
The transmembrane pore protein Pannexin-1 (Panx1) forms channels allowing the release of purine nucleotides and participates in processes related to purinergic signaling, including blood pressure regulation, apoptotic cell clearance, and neuropathic pain.

Pannexin 1 Regulates Bidirectional Hippocampal Synaptic Plasticity in Adult Mice

Frontiers in Cellular Neuroscience, 2014
The threshold for bidirectional modification of synaptic plasticity is known to be controlled by several factors, including the balance between protein phosphorylation and dephosphorylation, postsynaptic free Ca2+ concentration and NMDA receptor (NMDAR ...
