INHBA and psoriasis: Consequently, our in vitro model can, indeed, be used to identify genes with altered expression in psoriasis, and maybe new, yet unidentified genes as well, such as CXCL2, CXCL14, INHBA, EPO, TNFSF9, and IL1R2. Therefore, our results confirmed and extended previous studies highlighting the remarkable potential of keratinocytes to produce pro-inflammatory cytokines, adhesion molecules, growth factors, and chemotactic polypeptides [23].
