GATA3 regulates FLG and FLG2 expression in human primary keratinocytes.

ABSTRACT: GATA3 is a transcription factor with an important role in atopic diseases because of its role in the differentiation of Th2 lymphocytes. Moreover, GATA3 is expressed in keratinocytes and has a role in keratinocyte differentiation and the establishment of the epidermal barrier. In this study, we investigated the role of GATA3 in keratinocytes in the context of epidermal barrier integrity under inflammatory skin conditions. When analysing skin samples from atopic dermatitis and psoriasis patients or healthy controls, we detected decreased expression of GATA3 in the stratum spinosum and stratum granulosum of atopic dermatitis and psoriasis patients when compared to healthy controls. Our cell cultures experiments revealed that a downregulation in GATA3 by shRNA leads to a significant reduction
