Engineered Dual‐Function Antibody‐Like Proteins to Combat SARS‐CoV‐2‐Induced Immune Dysregulation and Inflammation

open access: yesAdvanced Science, EarlyView.
Engineered antibody‐like proteins block the SARS‐CoV‐2 spike protein from binding to host receptors and suppress immune overactivation through an MBL‐based scaffold. These dual‐function proteins effectively alleviate inflammation, complement activation, and lung injury, offering a promising therapeutic strategy against severe COVID‐19 and its ...

Cryo‐Inactivated Cancer Cells Derived Magnetic Micromotors for Tumor Immunotherapy

open access: yesAdvanced Science, EarlyView.
Cryo‐inactivated cancer cell‐based magnetic micromotors are developed for synergistic tumor immunotherapy via magnetic targeting. These micromotors can induce ferroptosis and immunogenic cell death, deliver tumor antigens, and activate the Mn2+‐dependent cGAS‐STING pathway. The system effectively suppresses tumor progression, recurrence, and metastasis,

Additive Manufactured Magnetoelectric Wireless Retainer as the Periodontal Remodeler for Post‐Orthodontic Tissue Reconstruction and Relapse‐Inhibition

open access: yesAdvanced Science, EarlyView.
Orthodontic relapse persists as a 120‐year challenge, as traditional retainers fail to remodel tissue, causing lifelong dependence. This study demonstrates a flexible magnetoelectric retainer (FMOR) enabling wireless periodontal remodeling. FMOR cues shift periodontal ligament cell (PDLC) paracrine signaling, promoting M2 macrophages, osteogenic ...

Lysosome‐Featured Cell Aggregate‐Released Extracellular Vesicles Regulate Iron Homeostasis and Alleviate Post‐Irradiation Endothelial Ferroptosis for Mandibular Regeneration

open access: yesAdvanced Science, EarlyView.
Lysosomal redistribution occurs via extracellular vesicles in multi‐stem cell aggregates and controls iron homeostasis for safeguarding cell aggregation. These cell aggregate‐released extracellular vesicles (CA‐EVs) rescue lysosomal impairments and exert anti‐ferroptosis effects in recipient irradiated endothelial cells.

An Amygdala‐hippocampus Circuit for Endocannabinoid Modulation of Anxiety Avoidance

open access: yesAdvanced Science, EarlyView.
This study employs three synapse‐specific endocannabinoids (eCB) probes to monitor dynamic eCB release, activate CB1Rs and knockdown 2‐AG biosynthesis enzymes in glutamatergic anterior basolateral amygdala ‐ ventral hippocampus (aBLA–vHPC) circuit. At aBLA–vHPC circuits, activation of CB1Rs reduce anxiety avoidance, and knockdown of eCB biosynthesis ...

A Subcircuit in the Suprachiasmatic Nucleus Generates Wakefulness

open access: yesAdvanced Science, EarlyView.
This study identifies a sub‐circuit within the circadian pacemaker suprachiasmatic nucleus (SCN) that promotes arousal. This sub‐circuit is labeled by the clock output molecule mWAKE, which suppresses its excitability in a time‐dependent manner. mWAKE‐expressing cells in the SCN (SCNmWAKE cells) project to the subparaventricular zone (SPZ) to mediate ...

Adipose Tissue Macrophages as Initiators of Exacerbated Periodontitis in Estrogen‐Deficient Environments via the Amplifier Extracellular Vesicles

open access: yesAdvanced Science, EarlyView.
Chronic systemic inflammation, worsened by estrogen deficiency, underlies and exacerbates periodontitis. Proinflammatory macrophages within visceral adipose tissue are hyperactivated due to hyper‐DNA methylation, releasing small extracellular vesicles (sEVs) similar to those of their parent cells.
