This study identified a long-range excitatory projection from parvalbumin (PV) neurons in the brainstem medial vestibular nucleus (MVN) of mice that monosynaptically innervates the midbrain dorsal tegmental nucleus (DTN). This PV<sup>MVN→DTN</sup> projection exhibits high neuronal excitability and synaptic plasticity as electrophysiological traits. In vivo chemogenetic inhibition of the PV<sup>MVN→DTN</sup> projection impaired the navigational performance of adult mice. Navigational deficits in aged mice linked to both diminished innervation and synaptic drive of the PV<sup>MVN→DTN</sup> pathway were pinpointed as hallmarks of the aging process.

We find that upregulation of the chromatin remodeler BAZ2B in a subpopulation of hepatocytes (HEPs) is linked to MASH pathology in patients. Genetic ablation or hepatocyte-specific knockdown of Baz2b in mice attenuates HEP senescence and MASH fibrosis by preserving peroxisome proliferator-activated receptor α (PPARα)-mediated lipid metabolism, which was impaired in both naturally aged and MASH mouse livers. Mechanistically, Baz2b downregulates the expression of genes related to the PPARα signaling pathway by directly binding their promoter regions and reducing chromatin accessibility.
