Super-Resolution Microscopy Reveals the Native Ultrastructure of the Erythrocyte Cytoskeleton

Cell Reports, 2018
Summary: The erythrocyte cytoskeleton is a textbook prototype for the submembrane cytoskeleton of metazoan cells. While early experiments suggest a triangular network of actin-based junctional complexes connected by ∼200-nm-long spectrin tetramers, later

Presbycusis: Pathology, Signal Pathways, and Therapeutic Strategy

Advanced Science, EarlyView.
In ARHL, the stria vascularis, acting as a cochlear battery, gradually loses its ability to maintain the endocochlear potential, leading to impaired hair cell function and progressive hearing loss. Single‐cell sequencing reveals age‐related cellular changes in the cochlea, providing insights into the underlying mechanisms of aging and potential ...

Injectable pH Responsive Conductive Hydrogel for Intelligent Delivery of Metformin and Exosomes to Enhance Cardiac Repair after Myocardial Ischemia‐Reperfusion Injury

Advanced Science, EarlyView.
Injectable pH responsive conductive hydrogel for intelligent delivery of metformin and exosomes to alleviate myocardial ischemia‐reperfusion injury. The hydrogel responds to the weakly acidic microenvironment of ischemic injury and can significantly reduce the production of intracellular ROS and enhance cardiac conduction, thereby resisting apoptosis ...

Bistability in filamentous actin through monomer-sequestration of an effector species [PDF]

arXiv
Filamentous actin, a species of dynamic protein polymers, is one of the main components of the cytoskeleton of eukaryotic cells. We formulate a class of models that predict the possibility of bistable steady states in populations of dynamic actin filaments.

hESCs‐derived Organoids Achieve Liver Zonation Features through LSEC Modulation

Advanced Science, EarlyView.
This article addresses the absence of zonation features in current organoid models by co‐culturing human embryonic stem cell‐derived hepatocytes with liver sinusoidal endothelial cells exhibiting distinct zonal characteristics. It demonstrates that differential WNT2 signaling from endothelial cells modulates hepatocyte zonation and metabolic functions,

Chronic Alcohol Exposure Alters the Levels and Assembly of the Actin Cytoskeleton and Microtubules in the Adult Mouse Hippocampus

Journal of Integrative Neuroscience
Background: Alcohol abuse, a prevalent global health issue, is associated with the onset of cognitive impairment and neurodegeneration. Actin filaments (F-actin) and microtubules (MTs) polymerized from monomeric globular actin (G-actin) and tubulin form ...

Synaptic Spine Head Morphodynamics from Graph Grammar Rules for Actin Dynamics [PDF]

arXiv
There is a morphodynamic component to synaptic learning by which changes in dendritic spine head size are associated with the strengthening or weakening of the synaptic connection between two neurons, in response to the temporal correlation of local presynaptic and postsynaptic signals.

Tumoroid Model Reveals Synergistic Impairment of Metabolism by Iron Chelators and Temozolomide in Chemo‐Resistant Patient‐derived Glioblastoma Cells

Advanced Science, EarlyView.
This study investigates the metabolic vulnerabilities of glioblastoma (GBM), an aggressive brain tumor. Research demonstrates that iron chelation therapy, in combination with standard chemotherapy, significantly enhances the efficacy of treatment against resistant GBM cells in a 3D tumoroid model.

Intracellular Formation of Synthetic Peptide Nanostructures Causes Mitochondrial Disruption and Cell Death in Tumor Spheroids

Advanced Science, EarlyView.
Synthetic peptide nanostructures, formed within cancer cells in response to glutathione, lead to mitochondrial dysfunction and cell death. The nanostructures significantly damage mitochondrial networks, impair cellular respiration, and induce cell death in both 2D cultures and 3D tumor spheroids.
