Fever

1. Pyrogens increase the production of interleukin-1 (IL-1) in phagocytic cells.

- IL-1 acts on the anterior hypothalamus to increase the production of prostaglandins. Prostaglandins increase the set-point temperature, setting in motion the heat-generating mechanisms that increase body temperature and produce fever.

2. Aspirin reduces fever by inhibiting cyclooxygenase, thereby inhibiting the production of prostaglandins. Therefore, aspirin decreases the set-point temperature. In response, mechanisms that cause heat loss (e.g., sweating, vasodilation) are activated.

3. Steroids reduce fever by blocking the release of arachidonic acid from brain phospholipids, thereby preventing the production of prostaglandins.
