Taylor et al showed constitutive TSLP expression in murine GI tract, and demonstrated that TSLP-TSLPR interactions were critical for host protection against intestinal nematode infection.[43] Additionally TSLP expression is induced at the barrier surface during allergic inflammation such as keratoconjuctivitis and atopic dermatitis [17,26]. This evidence concerns the gene TSLP and atopic eczema.
