New Appetite Regulating Neurons Discovered

Researchers have identified a previously unknown population of neurons in the hypothalamus that play a critical role in regulating appetite. These neurons express both leptin receptors and the BNC2 gene, making them highly responsive to hunger-suppressing signals and food-related sensory cues.

Neural Circuit Found to Regulate Chewing and Appetite

New research has uncovered a simple neural circuit that connects hunger signals to jaw movements required for eating. Scientists identified a three-neuron pathway involving the hormone leptin and BDNF neurons, which controls the jaw's motor function.

UV Light Increases Appetite But Suppresses Weight Gain

A new study reveals that UV exposure can increase appetite while simultaneously preventing weight gain. This unexpected finding is attributed to UV's influence on hormones and neurotransmitters, leading to increased energy expenditure and the browning of subcutaneous fat. These insights could pave the way for innovative approaches to combat obesity and metabolic disorders.

Leptin Helps Hungry Mice Choose Sex Over Food

When their brains are stimulated with leptin, an appetite-suppressing hormone, hungry mice prioritize mating and interacting with mice of the opposite gender over eating.

A Possible Neural Link Between Early Life Trauma and Binge-Eating Disorder Discovered

8 in 10 sufferers of binge eating disorders experienced trauma during childhood. Researchers discovered leptin is less effective in the lateral hypothalamus of those who suffered childhood trauma.

Exercise Makes Female Rats Hungrier and Sustains Weight Gain

Study in rats reveals sex differences may play a key role in the effectiveness of exercise as an appetite regulator. Exercising female rats ate more than those who did not partake in physical activity. The same effect was not seen in males.

How Neurons Reshape Inside Body Fat to Boost Its Calorie-Burning Capacity

Normally bushy networks of neural fibers within fat tissue shrink in the absence of leptin, but grow back when the hormone is administered in drug form. The alterations influence the ability to burn energy stored in fat in mouse models.

Don’t overdo omega-6 fat consumption during pregnancy

Consuming too much omega 6 during pregnancy has been linked to an increased risk of neurodevelopmental issues in babies and pregnancy complications. In mice who had higher levels of linoleic acid in their diets, researchers noted altered concentrations of inflammatory proteins and a decrease in hormones that regulate fetal growth and development. Researchers stress the effects of a high linoleic acid concentration in diet are the same for both animal models and humans.

New brain mechanisms regulating body weight identified: Rodent study

Interleukin-6 interacts with leptin in the lateral parabrachial nucleus to reduce food intake. Reducing IL-6 in the IPBL increases weight gain and could help explain why some are more prone to overeating and obesity.

Gut-Brain Connection Signals Behavioral Alterations While Eating: Worm Study

Researchers have identified neurons in the guts of C. elegans that detect when bacteria are ingested and release a neurotransmitter that signals the brain to halt locomotion.
