• iTBS in SCA3 Mice: Motor and Molecular Effects

  2026-09-09

  A 2026 study in The Cerebellum shows that intermittent theta-burst stimulation (iTBS), but not continuous theta-burst stimulation (cTBS) to the same extent, improves coordination and modifies cerebellar pathology in SCA3/MJD mice.

• Nanoparticle PTEN mRNA Reverses Trastuzumab Resistance

  2026-09-08

  Dong and colleagues developed a tumor-microenvironment-responsive nanoparticle platform for systemic PTEN mRNA delivery in trastuzumab-resistant HER2-positive breast cancer models.
