Foxp2+ neurons in the hypothalamus act as a biological thermostat that can freeze tumor growth from the inside out.
Hypothalamic cells contain a specific switch that triggers sustained therapeutic hypothermia on command. Traditional cancer treatments rely on external cooling like ice baths or cooling blankets to slow the metabolism of aggressive diseases. This internal cooling mechanism bypasses the normal shivering response that usually prevents the body from staying cold. Activating these neurons induces a deep state of hypothermia that effectively starves tumors without the need for any outside equipment. This method allows the body to use its own neural circuitry to manage temperature and fight disease. It transforms how doctors might eventually treat systemic cancers by using the brain to manipulate the body's entire metabolic state.

The inability to selectively trigger therapeutic hypothermia independent of environmental cooling has hindered causal analysis of its broader physiological benefits. Here, we employed P57, a natural product that pharmacologically induces therapeutic hypothermia circumventing external cold stress, to identify the neuronal substrates underlying hypothermia-induced antitumor effects. Integrating functional ultrasound imaging, activity-dependent neuronal labeling, and single-nucleus RNA sequencing,
