How do prostaglandins affect inflammation?

• A. They promote vasodilation and increase pain sensitivity
• B. They reduce blood supply to the area
• C. They enhance the formation of scar tissue
• D. They inhibit the migration of immune cells

Answer: (A)

Prostaglandins play a significant role in the inflammatory response, primarily by promoting vasodilation, which increases blood flow to the injured or affected area. This vasodilation is crucial because it allows for a greater influx of immune cells and nutrients, which are essential for the healing process. Additionally, prostaglandins also increase the sensitivity of pain receptors, which contributes to the sensation of pain often associated with inflammation. This heightened pain sensitivity serves as a protective mechanism, alerting the individual to potential harm and prompting them to limit movement in the affected area. The other options do not accurately describe the role of prostaglandins. For instance, they do not reduce blood supply to the area; instead, they enhance it. The formation of scar tissue is more closely associated with other growth factors and cytokines rather than a direct effect of prostaglandins. Lastly, prostaglandins do not inhibit the migration of immune cells; rather, they facilitate the inflammatory response by attracting immune cells to the site of injury or infection. Overall, prostaglandins are critical mediators in the inflammation process, with a clear impact on both vasodilation and the sensation of pain.
