Midbrain PAG Astrocytes Modulate Mouse Defensive and Panic‐Like Behaviors

open access: yesAdvanced Science, EarlyView.
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 ...

ZNRD2 Mediated Nucleoprotein Aggregation Impairs Respiratory Syncytial Virus Replication

open access: yesAdvanced Science, EarlyView.
During RSV infection, nucleoprotein (N) forms RNA‐bound oligomers. The host protein ZNRD2 binds to these oligomers, promoting their transition into insoluble aggregates. These aggregates simultaneously sequester functional N to restrict viral production and disrupt chaperonin assembly quality control by interfering with ZNRD2's role as an adaptor ...

DEL‐1 is an Endogenous Senolytic Protein that Inhibits Senescence‐Associated Bone Loss

open access: yesAdvanced Science, EarlyView.
Senescent bone marrow stromal cells accumulate in the aging bone microenvironment, promoting bone degeneration. DEL‐1, an endogenous secreted protein, acts as a natural senolytic that selectively eliminates these cells. By engaging a β3 integrin/CD73/adenosine/p38 MAPK/BCL‐2 pathway, DEL‐1 counters aging‐related bone loss, revealing promising ...

A Supramolecular Ferroelectric With Two Sublattices and Polarization Dependent Conductivity

open access: yesAdvanced Science, EarlyView.
Ferroelectric behavior in a supramolecular material with two, independently switchable, sublattices is demonstrated. The sublattices can be associated with the two dipolar groups in the compound. Moreover, the polarization is found to couple to the charge transport in the material, giving rise to a switchable, directional conductivity.
