Leptin Function, Signaling via the LepR, & Overall Physiological Effects

The video explores leptin, a hormone released by fat cells, and its role in regulating hunger and metabolism. It details leptin's biological effects, including inhibiting fat synthesis and promoting fat breakdown. The mechanism of leptin receptor signaling via the JAK-STAT pathway is explained, highlighting its impact on hunger and satiety through the hypothalamus. The video also discusses leptin's interaction with the sympathetic nervous system and the concept of leptin resistance, often linked to obesity and inflammation.
