Abstract

Psoriasis is a well known disorder of keratinization. In this disease, several reports revealed that dermal micro vessels are increased and angiogenic factors such as vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) are over-expressed. Angiogenesis may play an important role in the progression of psoriasis. Acitretin is widely used as an anti-psoriatic drug because of its potent action on keratinocyte growth and differentiation, but its effects on angiogenesis are uncertain. The goal of this immunohistochemical study was to investigate the effects of acitretin on the expression of VEGF in psoriatic lesions of the skin. We compared the expression levels of VEGF between pre- and post-acitretin treated skin - 10 psoriatic skin lesions and 3 normal (control) skins. The expressions of VEGF in psoriatic skin lesions were significantly higher than in normal control skin. The expressions of VEGF in psoriatic skin lesions post-treatment were lower than those pre-treatment. Acitretin revealed inhibitory effects on angiogenesis by reducing the expression of angiogenic factors such as VEGF in psoriatic skin lesions. We suggest that acitretin may be useful in therapeutic approaches to psoriasis management, possibly related to angiogenesis.

건선(psoriasis)은 각화(keratinization)의 장애에 의한 질병으로 잘 알려져 있다. 이 질병에있어서, 몇몇 보고에 따르면 피부 미세혈관이 증가되고, 혈관 신생 유도 인자들인 내피 성장 인자(VEGF) 및 섬유아세포 성장 인자(bFGF)가 과발현된다고 보고 되어져 있다. 신생혈관(angiogenesis)은 건선의 진행성에 있어 중요한 역할을 할지도 모른다. Acitretin은 keratinocyte 성장과 분화에 그것의 잠재적인 활동 때문에 anti-psoriatic 약으로 널리 이용된다. 그러나 신생혈관에 대한 효과는 여전히 불명확하다. 본 면역혈청학적 연구 목표는 건선염 피부에 있는 VEGF의 발현에 acitretin의 효과를 조사하기 위한 것이었다. 우리는 10명의 건선염 피부환자와 대조군으로 3명의 정상인 피부에 acitretin의 치료 전과 후의 VEGF의 발현량을 비교하였다. 치료 전 대조군인 정상인 피부에서보다 건선염 피부환자에서 VEGF의 발현은 명백히 높은 수준이었다. 건선염 피부환자에서 VEGF의 발현량은 acitretin 치료 후 치료 전과 비교시 감소되었다. Acitretin은 건선 피부에서 VEGF와 같은 혈관 신생 유도 인자의 발현을 감소 시켜 신생혈관형성에 있어 억제의 효과가 있음을 나타낸다. 우리는 신생혈관 관점에서 acitretin이 건선에 대한 치료 수단이 될 수 있다는 것을 제안한다.
