Cytokines vs. Chemokines: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on December 17, 2023
Cytokines are a broad category of small proteins important in cell signaling, while chemokines are a specific type of cytokine primarily involved in attracting white blood cells to infection sites.

Key Differences

Cytokines are small proteins released by cells, particularly immune cells, which act as signaling molecules to regulate immunity, inflammation, and hematopoiesis. Chemokines, a subset of cytokines, are specifically responsible for chemotaxis, guiding the movement of immune cells towards sites of inflammation or infection.

The role of cytokines is diverse, encompassing the regulation of the immune system's response to disease and infection, as well as mediating normal cellular processes. Chemokines, on the other hand, primarily focus on directing cells, especially leukocytes, to areas where their services are needed in the immune response.

Cytokines include various types such as interferons, interleukins, and tumor necrosis factors, each with a specific function in immune response modulation. Chemokines are characterized by their ability to induce directed chemotaxis in nearby responsive cells, playing a crucial role in immune surveillance.

The action of cytokines can be either local or systemic, influencing not only the immune system but also other physiological processes. Chemokines typically exert more localized effects, creating chemical gradients that guide cells to specific locations.

Dysregulation of cytokine production can lead to a range of diseases, including autoimmune disorders, inflammations, and cancers. In contrast, chemokine dysregulation is primarily associated with pathological conditions related to immune cell migration, such as chronic inflammation and metastasis.
