RESULTS: Cytokines are regulators of host responses to infection, immune responses, inflammation, and trauma. Some cytokines act to make disease worse (proinflammatory), whereas others serve to reduce inflammation and promote healing (anti-inflammatory). Attention also has focused on blocking cytokines, which are harmful to the host, particularly during overwhelming infection. Interleukin (IL)-1 and tumor necrosis factor (TNF) are proinflammatory cytokines, and when they are administered to humans, they produce fever, inflammation, tissue destruction, and, in some cases, shock and death.
The inflammatory response (inflammation) occurs when tissues are injured by bacteria, this happens when a part of your body is injured. leukocytes and plasma proteins gather to inflame the area to fight infection. is a nonspecific defense reaction to tissue damage caused by injury or infection. blood flow diminished or eliminated around the site of injury is not a function however. The <i>inflammatory response</i> (inflammation) occurs when tissues are injured by bacteria, <br /> this happens when a part of your body is injured.
