Non-POMC neurons, specifically GABAergic neurons, mediate leptin's direct effects on energy balance and food intake, influencing POMC neurons indirectly.
This suggests that treatments targeting only POMC neurons may fail to reduce appetite. Future therapies might need to target GABAergic neurons or other non-POMC pathways to effectively manage obesity via leptin signaling.

We further highlight how non- POMC, GABAergic neurons mediate leptin's direct effects on energy balance and influence POMC neurons.
Why this rating
Supported by multiple studies cited in the review, though the review itself is a secondary source.

More from this paper
- Leptin regulates glucose homeostasis through direct actions on POMC neurons, but does not regulate food intake or energy balance through direct actions on these same neurons.Strong
- POMC neurons expressing the glucagon-like peptide 1 receptor (Glp1r) are a distinct subpopulation from those expressing the leptin receptor (Lepr), and Glp1r-expressing POMC neurons may regulate energy balance.Good

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
