Extravasation of Borrelia burgdorferi Across the Blood–Brain Barrier is an Extremely Rare Event

open access: yesAdvanced Science, EarlyView.
Lyme disease is caused by vascular dissemination of the bacteria Borrelia. In a 3D tissue‐engineered microvessel model, Borrelia extravasation across the blood–brain barrier is extremely rare, implying that neuroborreliosis is not caused via direct cytotoxicity.

Role of Testosterone Signaling in Microglia: A Potential Role for Sex‐Related Differences in Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
Testosterone enhances Aβ‐induced autophagy in microglia via the non‐genomic testosterone receptor GPRC6A, promoting Aβ clearance by suppressing ERK phosphorylation and inhibiting mTOR activation. In male 5xFAD mice, testicular removal reduces microglial autophagy and Aβ clearance, which is restored by testosterone.

Neural Patterns of Social Pain in the Brain‐Wide Representations Across Social Contexts

open access: yesAdvanced Science, EarlyView.
Empathy arises from both physiological and social pain, yet their shared and context‐specific neural mechanisms remain unclear. Combining fMRI and multivariate pattern analysis, this study decodes overlapping empathy networks and distinct representations for social exclusion versus separation.

Accumulation of Damaging Lipids in the Arf1‐Ablated Neurons Promotes Neurodegeneration through Releasing mtDNA and Activating Inflammatory Pathways in Microglia

open access: yesAdvanced Science, EarlyView.
Arf1 defects activate the AKT‐mTORC1‐SREBP1‐FASN pathway to increase lipid synthesis and disrupt ER‐mitochondrial‐lysosomal homeostasis in neurons. Impaired mitochondria secrete damaged mtDNA via mitochondria‐derived extracellular vesicles, which is phagocytosed by the microglia and activated inflammation signaling.

Ultrasound‐Assisted H2 Transmitter Enables Hydrogen‐Gene Therapy to Prevent Anesthesia/Surgery‐Induced Cognitive Impairment

open access: yesAdvanced Science, EarlyView.
Postoperative cognitive dysfunction (POCD) remains a challenge with no effective treatments. This study introduces a novel hydrogen‐gene therapy strategy, combining focused ultrasound and siRNA delivery via hydrogen emitters, to repair neuroinflammation in a precise and controlled manner.

Altered Neural Activity in the Mesoaccumbens Pathway Underlies Impaired Social Reward Processing in Shank3‐Deficient Rats

open access: yesAdvanced Science, EarlyView.
This study examines the effects of Shank3 mutation on the mesoaccumbens pathway using a Shank3‐deficient rat model. The findings reveal altered social reward processing in these rats, accompanied by changes in dopaminergic and GABAergic neural activity within the ventral tegmental area (VTA) and dopamine release in the nucleus accumbense (NAc ...

Noninvasive Assessment of β‐Secretase Activity Through Click Chemistry‐Mediated Enrichment of Neuronal Extracellular Vesicles to Detect Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
This study presents the NEV β‐secretase activity assay, a groundbreaking method for noninvasive evaluation of β‐secretase activity in Alzheimer's disease (AD) patients, enabling the generation of individualized β‐secretase activity profiles.
