Prostaglandins contribute to which inflammatory features?

Explanation:
Prostaglandins act as key mediators of inflammation that specifically drive pain and fever. Inflammation releases COX-derived prostaglandins, especially PGE2, which lowers the threshold of nociceptors, making tissues more sensitive to pain (hyperalgesia). They also signal the hypothalamus to raise the body's temperature, producing fever. These effects explain why prostaglandins are tightly linked to pain and fever during inflammatory responses. They aren’t responsible for the production of immunoglobulins, which come from B cells and helper signals, nor do they cause hypertension as a defining inflammatory feature; while prostaglandins influence vascular tone, the hallmark inflammatory features tied to them are pain and fever.
