The Claim
Mutant thyroid hormone receptor α1 (TRα1) signaling in the hypothalamus of mice is associated with a sustained reduction in body temperature under thermoneutral conditions (30°C), indicating a central role for TRα1 in establishing the body's temperature baseline.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In mice, a mutation in the thyroid hormone receptor TRα1 in the hypothalamus results in a persistent drop in body temperature even when the environment is warm enough to maintain normal temperature.
See the scientific wording
Mutant thyroid hormone receptor α1 (TRα1) signaling in the hypothalamus of mice is associated with a sustained reduction in body temperature, even under thermoneutral conditions (30°C), suggesting a central role for TRα1 in setting the body's temperature baseline.
Thyroid hormone enters brain cells in the hypothalamus and binds to a specific receptor called TRα1. This binding turns on genes that set the body's target temperature. When this receptor does not work properly, the brain sets a lower target temperature, and the body reduces heat production and conservation even when the environment is warm, resulting in a persistently lower core temperature.
What the research says
1 studyStudy: Hypothalamic Thyroid Hormone Receptor α1 Signaling Controls Body Temperature
Scientists found that when a specific brain receptor (TRα1) doesn't work right in mice, their body temperature stays lower than normal—even in a warm room where they shouldn't need to conserve heat. This suggests the brain uses this receptor to decide what our normal body temperature should be.
