title: [Epidermic and lymphocytary chalone receptors in psoriasis].
abstract: By Hondius-Boldingh. Laurence and Bullough, Laurence method, the activity of the epidermal chalone receptors was studied in 36 psoriasis and 36 healthy controls. The lymphocyte chalone receptors was also studied in 26 patients, by Garcia Giralt et al. and Lasalvia et al. method. The results showed that the epidermal chalone receptors are significantly decreased in the involved skin, and in a lesser degree in the uninvolved one of the patients with psoriasis. The lymphocyte chalone receptors were normal. This decreasing in the function of the epidermal chalone system by means of different "antireceptor factors", interrupt the physiological cell control of the epidermis. The absence of the chalone specific function, produces an intracelular disbalance which provokes, in particular, the high number of mitosis and the lack of terminal differentiation. These elements admit that in psoriasis there is an abnormal epidermopoyesis. Over a genetic disorder, multiple factors leading to a deffect of the cell membrane. These factors, acquired, local or systemic interfering with the receptors of membrane, would alter the cellular regulation induced my the chalones.
