IL10 and allergic disease: Interleukin-10 (IL-10), an anti-inflammatory cytokine secreted under different conditions of immune activation by a variety of cell types, including T cells, B cells, and monocytes/macrophages [83], [84] has been shown to suppress a broad range of inflammatory responses and as an important factor in maintaining homeostasis of overall immune responses [85], [86] and thus has been used for developing novel therapies for several human diseases such as allergic responses and autoimmune diseases [87].
