cytokine receptors

Cytokine receptors are specialized proteins found on the surface of cells that detect and respond to signaling molecules called cytokines. Cytokines are crucial for communication between cells, particularly in the immune system, helping to regulate immune responses, inflammation, and cell growth. When a cytokine binds to its receptor, it triggers a series of actions within the cell, leading to various biological responses, like activating immune cells or promoting healing. Essentially, cytokine receptors act like antennas, allowing cells to receive important messages that coordinate the body’s defenses and overall health.
