Quizplus · Accepted Answer

Cytokines are small proteins that can stimulate or inhibit many normal cell functions. They are involved in immune responses and are often used in medical treatments to stimulate the immune system or reduce inflammation. Enzymes, kinins, MHC, and leukocytes are not hormones and do not have the same ability to regulate cell functions.
