cytok

Cytok is a term that refers to a cytokine, which is a broad and heavy term for any small protein secreted by cells of the immune system and some other cells. Cytokines are signaling molecules that mediate and regulate immunity, inflammation, and hematopoiesis. They are crucial for cell-to-cell communication within the immune system and play a vital role in coordinating the body's response to infection and injury. Cytokines can have diverse effects, including promoting or inhibiting cell growth, differentiation, and movement. They can also induce fever, activate immune cells, and contribute to the inflammatory process. Different types of cytokines exist, each with specific functions and targets. Examples include interleukins, interferons, and tumor necrosis factor. The dysregulation of cytokine production or signaling is implicated in a variety of diseases, including autoimmune disorders, cancer, and infectious diseases. Research into cytokines has led to the development of targeted therapies for many conditions.
