Story summary

A groundbreaking study shows that hunger signals in the brain can significantly impact immune cell levels in mice, regardless of food consumption. When hunger neurons are activated, monocyte counts drop, but fullness neurons bring them back. This intricate communication between the brain, liver, and immune system could play a crucial role in inflammation and metabolic diseases, paving the way for future human research.
