Interleukin-21 (IL-21) is a pleiotropic cytokine belonging to the γc-chain cytokine family, playing a central regulatory role in adaptive immunity and humoral immunity.

IL-6 (Interleukin-6) is one of the most versatile and widely influential core members in the cytokine network. It serves not only as a primary inducer of the acute-phase response but also as a critical messenger linking innate and adaptive immunity, while regulating hematopoietic, metabolic, and neuroendocrine systems.
