Retrospective Grid Cells in the Medial Entorhinal Cortex Encode Past Paths During Spatial Navigation

open access: yesAdvanced Science, EarlyView.
Retrospective grid cells are identified in the medial entorhinal cortex, with spatial firing patterns that become most grid‐like when activity is projected onto recently traversed locations. Their coding loses spatial precision in darkness and is disrupted during assisted movement, indicating that entorhinal representations incorporate recent path ...

Innovative Approach Reveals How Receptors Control G Protein State Equilibria

open access: yesAdvanced Science, EarlyView.
Using conformational specific trFRET biosensors of the Gi protein (depicted at the bottom), the authors show that receptor activation can not only release GDP from the inactive G protein, but can also release GTP from the activated G protein, leading to the reformation of the RG ternary complex.

A Spatiotemporal Single‐Cell Atlas Uncovers Dysregulated ECM Dynamics and Septal Remodeling Arrest in Human Ventricular Septal Defects

open access: yesAdvanced Science, EarlyView.
Integrating single‐cell and spatial transcriptomics reveals human ventricular septal defect (VSD) as a disease of microenvironmental insufficiency and structural remodeling arrest. Attenuated endothelial‐fibroblast crosstalk, alongside downregulated THBS1/TGF‐β1 and MMP2 signaling networks, impairs the endothelial‐to‐mesenchymal transition (EndoMT) and

Transthoracic Echocardiography as a Tool for Early Detection of Atrial Fibrillation in Patients Receiving Ibrutinib

open access: yesLife
Background: Bruton’s tyrosine kinase inhibitors, particularly ibrutinib, have improved outcomes in patients with chronic lymphocytic leukemia but are associated with an increased risk of atrial fibrillation.

Engineering a Bioelectronic Hybrid Heart with Integrated Sensing and Electrical Modulation

open access: yesAdvanced Science, EarlyView.
A bioelectronic hybrid heart is engineered by integrating iPSC‐derived cardiomyocytes, a decellularized cardiac scaffold, a cell‐laden ECM coating, and a flexible electronic mesh. The embedded electrodes enable real‐time recording of spontaneous electrical activity and localized stimulation, allowing controlled pacing and modulation of activation ...
