Abstract: Gap junctional intercellular communication (GJIC) is the ubiquitous communication mode in multicellular organisms and the function is achieved by connexin (Cx). A few of studies have showed the correlations between connexin 43 (Cx43) and psoriasis. The all-trans retinoic acid (ATRA) may affect the GJIC function of psoriatic keratinocytes. The effect of all-trans retinoic acid on gap junctional intercellular communication of keratinocytes in psoriasis is reviewed in this paper.

Key words: ATRA, GJIC, psoriasis, Cx43, IL-22
