Circadian clock protein Bmal1 regulates respiratory motor plasticity in male rats

Function
Acute intermittent hypoxia (AIH) elicits respiratory motor plasticity in the phrenic, intercostal, and hypoglossal motor pools and has emerged as a promising therapeutic strategy to improve respiratory function in people with neuromuscular disorders that

Human‐Scale Rotating Magnetic Field Delivery With Permanent Magnets Under Anatomic and Robotic Constraints

Advanced Robotics Research, EarlyView.
Rotating magnetic fields (RMFs) are widely used for microrobot propulsion and control. We show that RMF generation with permanent magnets is mechanically feasible for many limb and intracranial applications but becomes constrained for thoracic targets.

Microbiota–Metabolome Alterations Suggest Pro-Inflammatory Phenotype in Congenital Central Hypoventilation Syndrome

International Journal of Microbiology
Congenital central hypoventilation syndrome (CCHS) is a genetic disorder caused by mutations in the PHOX2B gene, characterized by impaired autonomic control of breathing and systemic consequences that may affect gut homeostasis.

CD9+ B Cells Induce T Follicular Helper Cell Apoptosis to Regulate Germinal Center Regression

Advanced Science, EarlyView.
A unique subset of CD9+ B cells regulates germinal center B (GC‐B) cell regression by inducing T follicular helper (Tfh) cell apoptosis through multiple signaling pathways, such as ALCAM‐CD6. FOXP1 plays a key role in GC‐B cell differentiation. These findings clarify mechanisms of GC degeneration and termination and offer potential targets for adenoid ...

Adenylyl cyclase isoforms 5 and 6 in the cardiovascular system: complex regulation and divergent roles

Frontiers in Pharmacology
Adenylyl cyclases (ACs) are crucial effector enzymes that transduce divergent signals from upstream receptor pathways and are responsible for catalyzing the conversion of ATP to cAMP.
