“…One of the most principal anti-inflammatory biological regulators within multisystem cytokine network of the human body is interleukin-4 (IL-4), which is predominantly produced by Th2-lymphocytes and mainly facilitates suppression of production of TNF-α, IL-1β, IL-6, IL-8 by monocytes/macrophages as well as decreased production of IL-2, IFN-γ and prostaglandins by activated macrophages and Th1-lymphocytes, resulting in weakening of excessive influence of inflammation mediators on the human body and simultaneous activation of humoral body response (increased IgE and IgG secretion) [12,13]. Like other components of cytokine network, IL-4 is a principal factor for implementation of different effector functions which are necessary to maintain cellular homeostasis.…”
