TSLP and atopic eczema: TSLP is expressed at barrier surfaces, and has been extensively studied in the context of T helper 2 (TH2) type responses and shown to promote the progression of TH2-mediated diseases, including asthma, atopic dermatitis, and allergic inflammation (Al-Shami et al., 2005; Divekar and Kita, 2015; Yoo et al., 2005; Zhou et al., 2005), as well as immune responses to the intestinal pathogen, Trichuris muris (Taylor et al., 2009), but the role of TSLP on CD8+ T-cell responses is less-well characterized.
