Vaspin--a link of obesity and psoriasis?

Abstrakt
Psoriasis is an inflammatory skin disease often associated with obesity. The anti-inflammatory adipokine vaspin, a suggested serine proteinase inhibitor of the serpin family, is discussed as a new link between inflammation and obesity. Here, we demonstrate that - different from healthy controls - vaspin serum levels in patients with psoriasis were body mass index independent. Moreover, we could identify keratinocytes as the major source of vaspin in skin. Vaspin expression in lesional psoriatic skin was reduced compared with uninvolved skin as shown by immunohistochemistry and RT-PCR. In aggregate, we report on the cellular source of vaspin in skin and its expression in psoriasis.
