Step 1

Cytokines:

Cytokines are a diverse group of signaling molecules that are produced by a wide range of cells, including immune cells, and play critical roles in cell-to-cell communication in the immune system and other biological processes.

Cytokines are typically small proteins that bind to specific receptors on target cells, triggering a range of cellular responses, including proliferation, differentiation, and activation of immune cells. They can also regulate inflammation, immune responses, and other biological processes.
