Maternal Choline Supplementation in a Mouse Model of Down Syndrome and Alzheimer’s Disease Generates Unique Expression Profile Mosaics Within Three Hippocampal Excitatory Neuronal Populations

open access: yesThe FASEB Journal, Volume 40, Issue 7, 15 April 2026.
Maternal choline supplementation (MCS) is utilized in the Ts65Dn mouse model of Down syndrome (DS) and Alzheimer's disease (AD). At ~6 months of age, laser capture microdissection and single population RNA‐sequencing of three hippocampal neuron populations (CA1 and CA3 pyramidal neurons and dentate gyrus granule cells) were conducted.

Region‐to‐Region Unidirectional Connection In Vitro Brain Model for Studying Directional Propagation of Neuropathologies

open access: yesAdvanced Functional Materials, Volume 36, Issue 33, 23 April 2026.
A unidirectional cerebral organoid–organoid neural circuit is established using a microfluidic platform, enabling controlled directional propagation of electrical signals, neuroinflammatory cues, and neurodegenerative disease–related proteins between spatially separated organoids.

Midbrain PAG Astrocytes Modulate Mouse Defensive and Panic‐Like Behaviors

open access: yesAdvanced Science, Volume 13, Issue 19, 2 April 2026.
Astrocytes in the midbrain periaqueductal gray (PAG) dynamically encode threat intensity and shape defensive action selection in mice. Real‐time Ca2+ imaging reveals robust astrocytic activation during predator odor and CO2 exposure. Aberrant astrocytic Ca2+ overactivation disrupts goal‐directed escape, biases behavior toward freezing, and induces ...

Amyloid β Instigates Cardiac Neurotrophic Signaling Impairment, Driving Alzheimer's Associated Heart Disease

open access: yesAdvanced Science, Volume 13, Issue 20, 9 April 2026.
This research identified cardiac amyloid pathology, neurotrophic factor depletion, and reduced myocardial nerve function in a transgenic model of cerebral amyloidosis (Tg2576), Aβ‐challenged cardiomyocytes, and in human AD heart tissue. These findings carry significant diagnostic and therapeutic implications, emphasizing the role of neuro‐signaling ...

Respiratory‐Limbic Coupling via a Thalamic Circuit Alleviates Anxiety

open access: yesAdvanced Science, Volume 13, Issue 24, 27 April 2026.
This study delineates a conserved preBötCGlu→PVT→CeA circuit that gates anxiety and respiration. Activation of this circuit is anxiolytic and respiratory‐stabilizing, while its inhibition has the opposite effect. Mechanistically, PVT exerts its anxiolytic action via a disinhibitory microcircuit: its inputs preferentially target CeL GABAergic neurons ...

Cortical Somatostatin Neurons Regulate Seizure Susceptibility via MINAR1/Gαs–cAMP Signaling

open access: yesAdvanced Science, Volume 13, Issue 21, 13 April 2026.
Our study identifies MINAR1 as a novel regulator of cortical interneuron excitability and seizure susceptibility. MINAR1 is preferentially expressed in SST+ interneurons. Genetic ablation of MINAR1 leads to seizure hypersensitivity, reduced SST+ neuron excitability, and impaired Gαs–cAMP signaling, disrupting the E/I balance.

Ferroptosis: The Demise of Cells Through Phospholipid Peroxidation

open access: yesAdvanced Science, Volume 13, Issue 23, 23 April 2026.
The relative abundance of peroxidation‐resistant monounsaturated fatty acids (MUFAs) vs. peroxidation‐sensitive polyunsaturated fatty acids (PUFAs) incorporated into phospholipid (PL) is a key determinant of ferroptosis sensitivity, as the peroxidation of PL PUFA acyl chains (PUFA‐PL) disrupts membrane integrity, causing ferroptotic cell death ...
