Linn. Extract Increases the mRNA Expression of the Arcuate Nucleus Leptin Receptor and is Predicted as an Anti-obesity Agent.

Background: Leptin is predominant in regulating body weight by stimulating energy expenditure through its neuronal action in the brain. Moreover, it is projected to adipose tissue and induces adipocyte browning by activating the β3-adrenergic receptor (β3AR). However, the expression of leptin receptor (Lep-R) and β3AR in people with obesity is downregulated.
