What are the similarities between cytokines and hormones?

Posted November 16, 2023


One similarity is that cytokines and some hormones are proteins. Cytokines are signaling proteins, while hormones are secretory proteins. Both are also involved in cellular communication. Cytokines and hormones also travel through the bloodstream, to reach their target cell or tissue. They both bind with the receptors to induce some type of activity. Both molecules also act as chemical messengers, as they direct different cellular behavior.
