A
Interferons.
B
Chemokines.
C
Interleukins.
D
Tumor necrosis factors.
Verified step by step guidance1
Understand the role of cytokines in the immune system: Cytokines are signaling proteins that mediate and regulate immunity, inflammation, and hematopoiesis.
Identify the function of chemokines: Chemokines are a specific type of cytokine that primarily function to recruit immune cells to sites of infection, inflammation, or tissue damage.
Differentiate between the types of cytokines: Interferons are involved in antiviral responses, interleukins are involved in communication between white blood cells, and tumor necrosis factors are involved in systemic inflammation.
Recognize the specific role of chemokines: Chemokines create a chemical gradient that guides immune cells to the site where they are needed, such as areas of infection or injury.
Conclude that chemokines are the cytokines responsible for recruiting immune cells to the site of infection, inflammation, or tissue damage.
