Dr. Song discovered circuit proteins responsible for negative feedback loop for HPT-axis and switched to positive feedback control loop instead. Describe what would happen to thyrotropin releasing hormone, thyrotropin, and thyroxine when thyroxine level is lower than the normal level (lower than the set point).
