01 / DESIGN
What was studied?
A cross-species cell atlas was combined with spatial mapping and functional experiments in rat brainstem populations.
02 / FINDINGS
What did the researchers report?
One receptor-expressing population changed gene expression without producing sustained feeding effects when activated. A different prolactin-releasing-hormone population was implicated through knockdown experiments.
03 / LIMITS
How should it be interpreted?
Expression and causal function are different types of evidence. Cross-species conservation does not establish identical human responses or prove the effects of an unrelated preparation.
