To determine the TSLP autocrine/paracrine regulation in co‐cultures of mutantGFP with non‐mutantTom KCs, we purified by FACS GFP+ and Tomato+ KCs after TSLP neutralization and analyzed gene expression of pro‐inflammatory mediators in psoriasis‐like disease (Fig EV5D–M). Here, TSLP is linked to psoriasis.
