Final answer:
Yes, the action of cytokines is antigen dependent. Cytokines are signaling molecules secreted by cells to communicate with each other. They induce changes in the receiving cell's physiology.
Step-by-step explanation:
Yes, the action of cytokines is antigen dependent.
Cytokines are signaling molecules secreted by cells to communicate with each other.
They induce changes in the receiving cell's physiology
. In the context of the immune system, cytokines are secreted by T cells in response to antigen stimulation, and they play a crucial role in coordinating the immune response.
For example, when a CD4+ helper T cell binds to an MHC II-antigen complex on an antigen-presenting cell, both the antigen-presenting cell and the T cell release cytokines.
These cytokines stimulate the activation of other immune cells and regulate the immune response.
In summary, the action of cytokines is antigen dependent and plays an important role in the immune response.
