In fever production
A) Endogenous pyrogen released from neurons of the cerebral cortex in response to an infection elevates the hypothalamic "set point."
B) Eold response mechanisms are initiated by the hypothalamus to raise the body temperature to the new set point.
C) Heat loss mechanisms are triggered to eliminate the excess heat from the body.
D) Endogenous pyrogen released from neurons of the cerebral cortex in response to an infection elevates the hypothalamic "set point," and cold response mechanisms are initiated by the hypothalamus to raise the body temperature to the new set point.
E) Endogenous pyrogen released from neurons of the cerebral cortex in response to an infection elevates the hypothalamic "set point," and heat loss mechanisms are triggered to eliminate the excess heat from the body.

Endogenous pyrogens, typically cytokines, are released by immune cells, not neurons, and they elevate the hypothalamic set point. The hypothalamus then initiates cold response mechanisms like shivering to raise the body temperature to the new set point.
