To determine whether local neutralization of TSLP reduces epidermal cell proliferation and psoriasis‐like progression in vivo, intradermal injections of TSLP antibody were applied to the right ear of both mouse models, DKO* and DKO*K15, 5 days after psoriasis‐like induction (Fig 6G). The gene discussed is KRT15; the disease is psoriasis.
