Quizplus · Accepted Answer

Cytokines are indeed chemicals that play a critical role in the immune system by communicating between cells to initiate, amplify, and modulate immune responses. They are involved in various processes, such as inflammation, cell differentiation, cell migration, and cell death, and they interact with different immune cells, including T cells, B cells, natural killer cells, and macrophages. Moreover, cytokines are produced by various cell types, including lymphocytes, monocytes, macrophages, dendritic cells, and endothelial cells, and they can act in an autocrine, paracrine, or endocrine manner. Therefore, cytokines are essential mediators of both innate and adaptive immunity.
