Research Abstract |
Psoriasis vulgaris is one of chronic inflammatory skin diseases. Its pathogenesis remains to be completely elucidated. SLURP-2, a secreted Ly-6/uPAR related protein-2 is a secretory protein, which is significantly upregulated in the psoriatic lesion. SLURP-2/FLAG expression vector was constructed, followed by the transfection into normal human epidermal keratinocytes. The transfected keratinocytes showed the overexpression of the proinflammatory cytokines or antimicrobial peptides that are upregulated in psoriasis. Those cells were co-cultured with blood cells from healthy subjects. The epidermal keratinoyctes in three-dimensional culture system, which were cultivated with the supernatant of co-culture, resulted in acanthotic epidermal architecture. These findings suggest that SLURP-2 may be involved in the pathophysiology of psoriasis.
