Prion-like transmission of human tau strains in the mouse brain

Abstract Most neurodegenerative diseases are thought to spread through the brain by prion-like mechanisms, in which filamentous protein assemblies self-propagate by templated seeding 1 . Distinct conformations of amyloid filaments may provide the physical basis for the strains th...

Sensory nerves regulate bone homeostasis in response to mechanical unloading or reloading: evidence from a spaceflight experiment and ground-based mechanical unloading models

Mechanical loading is crucial for maintaining bone mass, and understanding how bone remodels in response to mechanical loading is essential for treating musculoskeletal disorders. Recently, sensory nerves inside bone were identified as mechanical regulators of bone homeostasis. H...

Derivation of human post-mitotic cardiomyocytes from tetraploid iPSCs

Human induced pluripotent stem cell (iPSC)-derived cardiomyocytes (iPS-CMs) have great potential in regenerative medicine. However, iPS-CMs are immature and resemble fetal cardiomyocytes, restricting their application. Fetal cardiomyocytes in the human heart are diploid and proli...
