Role of interleukin-13 in innate and adaptive immunity.
Initially thought to be functionally redundant with IL-4 as a predominant anti-inflammatory factor secreted during type-2 T-cell responses, IL-13 possesses a number of additional properties that distinguish it from IL-4 in addition to having both anti-inflammatory and immune activating properties. This review centers primarily on the role of IL-13 in the regulation of cellular functions of innate immunity and acquired immunity against certain microbial pathogens. First, we discuss IL-13's regulation of innate cell targets and its impact on inflammation, antigen uptake and antigen presentation. Second, we focus on IL-13's involvement in acquired immunity to infectious helminths and protozoa. The role of this cytokine in immune responses is still being determined but evidence to date suggests this molecule has been conserved as an important regulatory factor involved in both early innate and late adaptive responses.
