转化生长因子-α(TGF-α)是一种有效的上皮细胞有丝分裂原,在正常表皮中低水平表达,在银屑病中过表达。表皮生长因子(EGF)已被证明可以抑制毛发生长,但刺激皮脂腺和汗腺的生长,这表明EGF/TGF-α家族成员在皮肤附件和表皮的正常发育和功能中具有潜在作用。目前的工作表明TGF-α蛋白存在于外分泌管、外分泌腺、皮脂腺和顶泌腺中。与已分化的外根鞘毛囊上皮细胞相比,增生的真皮毛球不表达TGF-α。此外,过度增生性皮肤病包括大疱性先天性鱼鳞病样红皮病、鳞状细胞癌和银屑病显示TGF- α表达增加。因此,TGF-α可能在正常皮肤附件的形态发生和功能中起作用,并且其过表达在良性和恶性过度增殖性皮肤疾病中是常见的。
Transforming growth factor-α (TGF-α) is a potent mitogen for epithelial cells that is expressed at low levels in normal epidermis and overexpressed in psoriasis. Epidermal growth factor (EGF) has been shown to inhibit hair growth but stimulate the growth of sebaceous and sweat glands, suggesting a potential role for a member of the EGF/TGF-α family in the normal development and function of skin appendages as well as epidermis. The present work demonstrates TGF-α protein in eccrine ducts, and eccrine, sebaceous, and apocrine glands. The proliferative dermal hair bulb does not express TGF-α in contrast to the differentiated outer root sheath hair follicle epithelia. In addition, hyperproliferative skin diseases including bullous congenital ichthyosiform erythroderma, squamous cell carcinoma, and psoriasis show increased TGF- α expression. Thus, TGF-α may play a role in the morphogenesis and function of normal skin appendages and its over-expression is common in benign and malignant hyperproliferative skin diseases.
