Herpes Simplex Virus Type 1 Neuronal Infection Perturbs Golgi Apparatus Integrity through Activation of Src Tyrosine Kinase and Dyn-2 GTPase

Frontiers in Cellular and Infection Microbiology, 2017
Herpes simplex virus type 1 (HSV-1) is a ubiquitous pathogen that establishes a latent persistent neuronal infection in humans. The pathogenic effects of repeated viral reactivation in infected neurons are still unknown.

Mechanically Regulated Secretion: How Physical Forces Instruct the Secretory Pathway and Remodel the Secretome

Advanced Science, EarlyView.
Mechanical cues, including ECM stiffness, stretch, compression, shear stress, and traction forces, remodel trafficking across the secretory pathway, from the ER and Golgi to endolysosomal compartments and the plasma membrane. The resulting secretome reshapes ECM composition and tissue mechanics, establishing feedback loops that support homeostasis or ...

Sensing Exocytosis and Triggering Endocytosis at Synapses: Synaptic Vesicle Exocytosis–Endocytosis Coupling

Frontiers in Cellular Neuroscience, 2018
The intact synaptic structure is critical for information processing in neural circuits. During synaptic transmission, rapid vesicle exocytosis increases the size of never terminals and endocytosis counteracts the increase. Accumulating evidence suggests

Cellular Mechanisms Enabling Mitochondria Transfer and Transplantation

Advanced Science, EarlyView.
Mitochondrial transfer and transplantation (mitoTT) is examined as a multistep process governed by distinct transfer routes and post‐transfer checkpoints. Mechanisms controlling mitochondrial uptake, network integration, cristae remodeling, mtDNA maintenance, immune sensing, and quality control are highlighted, revealing key biological and ...

FAK Mediated Coordination of Extracellular Matrix Remodeling and Cellular Mechanics Impairs Nanomedicine Delivery in Solid Tumors

Advanced Science, EarlyView.
FAK orchestrates a mechanical barrier limiting nanomedicine accumulation in solid tumors by coupling ECM remodeling with cytoskeletal tension. Genetic or pharmacological FAK inhibition dismantles this barrier, enhances clathrin‐mediated uptake and penetration, and overcomes delivery limitations to improve antitumor efficacy.

A Novel Reactive Oxygen Species‐Responsive Bone‐Targeted Nanoplatform Based on Cloperastine Attenuates Ovariectomy‐Induced Bone Loss by Inhibiting Osteoclast Oxidative Phosphorylation

Advanced Science, EarlyView.
Cloperastine suppresses osteoclastogenesis by inhibiting PGC1β‐mediated oxidative phosphorylation. Its incorporation into a ROS‐responsive, Asp8‐modified nanoplatform enhances skeletal accumulation. The resulting Clo/Asp8‐PMK‐MCs combine cloperastine‐mediated antiresorptive activity with carrier‐mediated osteogenic activity to attenuate OVX‐induced ...

Mn/Zn Bimetallic MOF‐Integrated Hydrogel Alleviates Excessive Mitochondrial Fission in BMSCs to Promote Osteoporotic Jawbone Repair

Advanced Science, EarlyView.
Excessive reactive oxygen species (ROS) and chronic inflammation impair bone marrow‐derived mesenchymal stem cells (BMSCs), contributing to poor healing in osteoporotic jawbone defect. The gelatin methacryloyl hydrogel loaded with manganese‐doped zeolitic imidazolate framework (Mn‐ZIF‐8@GelMA) promotes regeneration through redox regulation and ...

Mitochondrial Quality Control in Degenerative Musculoskeletal Diseases: Signaling Networks and Therapeutic Landscapes

Advanced Science, EarlyView.
Mitochondrial quality control (MQC) collapse redefines osteoarthritis, intervertebral disc degeneration, and osteoporosis as disorders of organelle dysfunction. Damaged mitochondria leak mtDNA and metabolites, driving cGAS‐STING inflammation, epigenetic reprogramming, and metabolic memory.

Structural inhibition of dynamin-mediated membrane fission by endophilin

eLife, 2017
Dynamin, which mediates membrane fission during endocytosis, binds endophilin and other members of the Bin-Amphiphysin-Rvs (BAR) protein family. How endophilin influences endocytic membrane fission is still unclear.
