What happened
Researchers report that many benefits of caloric restriction and increased NAD+ may depend on cilia of hypothalamic neurons. In mice, cilia length and NAD+ both declined with age in the hypothalamus, and NAD+ depletion or repletion changed cilia length in cultured neurons and in young mice. In aged mice on caloric restriction, silencing a key ciliary growth gene in the hypothalamus blocked some metabolic improvements, which the authors say shows these cilia are required.
“hypothalamic primary cilia are required for the CR–induced improvements in aging–associated metabolic phenotypes” — the study authors
