Proinflammatory cytokines

Proinflammatory cytokines are signaling proteins released by immune cells to promote inflammation, helping the body fight infections or heal injuries. They coordinate the immune response by attracting immune cells to the affected area, increasing blood flow, and activating other immune defenses. While essential for defense, excessive or chronic production of these cytokines can lead to prolonged inflammation, contributing to diseases like arthritis or autoimmune disorders. They act as messengers that regulate the intensity and duration of inflammation, ensuring a balanced response critical for maintaining health.
