In the great words of Dr Sattar:

"Prostaglandin E2 mediates feeeeeeeeeever"

NSAIDs --> block prostaglandin syn

temmy  Me it was so weird +  
peridot  I do want to add, that while PGE2 is the right answer, FA19 p.213 says that IL-1 and TNF are involved as well. However, because the question asks about what is going on in the hypothalamus, the answer is PGE2. If the question had been asking about what the macrophages were releasing to influence the hypothalamus, then the answer would have been IL-1 or TNF (FA didn't specify if it was TNF-a though...). +

Elevations in body temperature occur when concentrations of prostaglandin E(2) (PGE(2)) increase within certain areas of the brain.These elevations alter the firing rate of neurons that control thermoregulation in the hypothalamus.. It is now clear that most antipyretics work by inhibiting the enzyme cyclooxygenase and reducing the levels of PGE(2) within the hypothalamus.
