CCDC18 and psoriasis: These correlations may partly be explained by LINC01137, CCDC18-AS1, and CARMN that induce activation of CD4+T cells, myeloid DCs, neutrophils, macrophages, and Tfh cells and exhibit Treg cells involved in the immunopathogenesis of psoriasis, whereas LINC01215, MAPKAPK5-AS1, TPT1-AS1, EPB41L4A-AS, and LINC01214 work in the opposite way.
