Microglial GPR35 Ameliorates Epileptogenesis and Neuroinflammation via PDGFA Domain 2 Signaling

open access: yesAdvanced Science, EarlyView.
Activation of microglial G protein–coupled receptor 35 (GPR35) by L‐kynurenic acid (L‐Kyna) initiates a platelet‐derived growth factor A (PDGFA)–dependent phosphoinositide 3‐kinase–protein kinase B (PI3K–AKT) signaling cascade that dampens hippocampal neuroinflammation, thereby restraining epileptogenesis, lowering seizure susceptibility, and ...

Immunoaffinity‐Mimetic Assembly of Peptide‐Aptamer Conjugates and Stem Cell‐Derived Exosomes into Hierarchical Microgels for Spinal Cord Injury Repair

open access: yesAdvanced Science, EarlyView.
Inspired by antibody‐antigen binding, this study develops an unprecedented immunoaffinity‐mimetic assembly strategy, with Peptide‐AptCD63 conjugates acting as antibody surrogates binding CD63 epitopes on mesenchymal stem cell‐derived exosomes. This creates a hierarchical microstructure intended to synergistically integrate antioxidative and anti ...

Neuronal Cholesterol Deficiency Mediated by Astrocytic SREBP2 Downregulation Leads to Postoperative Cognitive Dysfunction Through Impairment of Hippocampal Synaptic Plasticity and Excitatory Synaptic Transmission

open access: yesAdvanced Science, EarlyView.
The results showed that the reduction of plasma 24‐hydroxycholesterol (24‐OHC) was related to the cognitive decline in elderly surgical patients. Neuroinflammation induced by anesthesia and surgery significantly downregulated SREBP2 in hippocampal reactive astrocytes, resulting in reduced cholesterol synthesis.

PVNCRF Neurons Regulate Migraine‐Like Allodynia by Activating CRFR2 on Spinal Trigeminal Caudalis Glutamatergic Neurons

open access: yesAdvanced Science, EarlyView.
Paraventricular CRF neurons in the hypothalamus project to glutamatergic neurons of the spinal trigeminal caudal nucleus, enhancing neuronal activation and CRFR2 signaling. This pathway increases CRF release and excitatory drive, promoting central sensitization and migraine‐related behaviors. Targeting the PVN–SP5C circuit provides a potential strategy

La confianza en el carácter de Dios y la salud mental

open access: yesPensamiento Americano, 2018
Introducción. La “salud mental”, conlleva implicaciones epistemológicas en la medida que se adopten posturas que varían desde posiciones positivas (como un “estado de completo bienestar “) o negativas, incluso si se admite,

Decoupling the Transparency‐Efficiency Trade‐Off in Semi‐Transparent Organic Solar Cells via Optimized Dual‐Channel Photoelectric Conversion

open access: yesAdvanced Science, EarlyView.
The respective roles of the heterojunction (HJ) and spontaneously formed photo‐charge (SP) channels in low‐donor‐content devices have been decoupled and subjected to a targeted optimization strategy. A breakthrough of light utilization efficiency (LUE) in semi‐transparent organic solar cells (ST‐OSCs) is achieved.

Tomás de Aquino y la pluralidad de ideas divinas. Los argumentos de un debate medieval

open access: yesStudium: Filosofía y Teología, 2016
Entre los textos en los que Tomás de Aquino sostiene que existen muchas ideas en la mente divina, hay uno que no ha recibido hasta ahora demasiada atención por parte de los investigadores y permanece casi inexplorado: el Quodlibet, IV, q. 1. Este escrito,

Dorsal Raphe VIP Neurons Are Critical for Survival‐Oriented Vigilance

open access: yesAdvanced Science, EarlyView.
DRNVIP neurons in mice and primates are strategically positioned to influence the central extended amygdala via feedback loops. They regulate the excitability of PKC‐δ neurons in the ovBNST and CeA through glutamate release. Their ablation heightens activity in these regions, disrupts active‐phase sleep architecture, enhances risk assessment behaviors ...
