What are cytokines and their significance in tissue repair?

Cytokines are small proteins secreted by immune cells that play a crucial role in cell signaling during the immune response. Their significance in tissue repair stems from their ability to modulate various physiological processes, including inflammation, cell growth, and tissue regeneration. When an injury occurs, cytokines are released at the site of damage to recruit and activate immune cells, orchestrate inflammatory responses, and facilitate the healing process.

Through the actions of cytokines, the body can initiate repair mechanisms, promote tissue regeneration, and restore homeostasis. This makes them vital in post-operative management in orthopaedic rehabilitation, as effective tissue repair is essential for recovery and regaining function. Understanding the role of cytokines can help healthcare providers better manage healing and rehabilitation protocols for patients undergoing surgery.
