Astrocytic Phenotypic Switching in Posterior Piriform Cortex Orchestrates Bone Cancer Pain–Depression Comorbidity via Purinergic–Noradrenergic Signaling

Advanced Science, EarlyView.
Bone cancer pain and depression share a common origin: astrocytic A2‐to‐A1 transition in the posterior piriform cortex. This phenotypic shift disrupts the ATP–adenosine–A2AR–norepinephrine axis, simultaneously driving nociceptive and affective dysfunction.

The origin of dorsoventral polarity in Drosophila [PDF]

Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2003
In Drosophila dorsoventral (DV) polarity arises during oogenesis when the oocyte nucleus moves from a central posterior to an asymmetrical anterior position. Nuclear movement is a symmetry–breaking step and establishes orthogonality between the anteroposterior and the DV axes.

Astrocytic FDX1 Contributes to Copper Dyshomeostasis‐associated Synaptic Dysfunction in Depression and Is Modulated by Exercise

Advanced Science, EarlyView.
Chronic stress disrupts copper homeostasis and promotes copper accumulation in the prelimbic cortex, leading to astrocytic FDX1 upregulation. Elevated astrocytic FDX1 impairs calcium signaling, induces structural atrophy, and disrupts synaptic function, contributing to depressive‐like behaviors. Physical exercise reverses these alterations by restoring

β-adrenergic receptor-induced E-S potentiation in the dorsal and ventral hippocampus

Frontiers in Synaptic Neuroscience
β-adrenergic receptors (β-ARs) play a critical role in modulating learning, memory, emotionality, and long-term synaptic plasticity. Recent studies indicate that β-ARs are necessary for long-term potentiation (LTP) induction in the ventral hippocampus ...

Shake a tail feather: the evolution of the theropod tail into a stiff aerodynamic surface.

PLoS ONE, 2013
Theropod dinosaurs show striking morphological and functional tail variation; e.g., a long, robust, basal theropod tail used for counterbalance, or a short, modern avian tail used as an aerodynamic surface.

Palmitoylation of PSD‐95 Orchestrates Learning‐Dependent Metaplasticity in the Amygdala and Fear Memory

Advanced Science, EarlyView.
This study reveals that fear learning specifically triggers PICK1/DHHC2‐dependent palmitoylation of PSD‐95 in the lateral amygdala. Fear conditioning induces the dissociation of DHHC5 from PSD‐95 and the association of PSD‐95 with DHHC2. DHHC2‐mediated palmitoylation of PSD‐95 is required for synaptic transmission and underlies fear learning–induced ...

Dorsoventral regulation of photosynthetic functions related to morphological and anatomical structures in field-grown sorghum

Photosynthetica, 2019
The rapid dorsoventral regulation of photosynthesis is important because the light conditions around both surfaces of field-grown leaves vary considerably.

BMP suppresses WNT to integrate patterning of orthogonal body axes in adult planarians.

PLoS Genetics, 2023
Adult regeneration restores patterning of orthogonal body axes after damage in a post-embryonic context. Planarians regenerate using distinct body-wide signals primarily regulating each axis dimension: anteroposterior Wnts, dorsoventral BMP, and ...

Fatty Acid Binding Protein 5 Mediates Astrocytic Pyroptosis and Neuroinflammation in Epilepsy via cGAS/STING Pathway

Advanced Science, EarlyView.
Astrocytic FABP5 promotes mitochondrial stress, cGAS‐STING pathway activation, pyroptosis, and neuroinflammation in epilepsy, contributing to seizure pathology. Genetic targeting of FABP5 or pharmacological inhibition of STING alleviates epileptic phenotypes, highlighting a potential therapeutic strategy for epilepsy.

Structural Polymorphism of polyG Inclusions Revealed by In Situ Cryo‐Electron Tomography

Advanced Science, EarlyView.
Correlative cryo‐electron tomography in primary cortical neurons and NIID mouse brain tissue reveals that polyG inclusions are interconnected ribbon‐like assemblies rather than canonical amyloid fibrils. Multiple compartment‐specific ribbon states show distinct 26S proteasome accessibility, while cytoplasmic ribbons contact and deform ER‐like ...
