IL10 and atopic eczema: For instance, research has shown that IgG from patients with Atopic Dermatitis influences IL-17, IL-22 and IL-10 production by T cells [17,18], IgG from non-atopic donors can mediate the regulation of IL-17, IFN-γ and IL-10 production by T cells [19], and IgG from both HIV-1-exposed non-infected and infected individuals can modulate IFN-γ production by T and B cells [20].
