Abstract:In previous studies, high levels of acetylcholine (ACh) have been reported in psoriasis lesions. In addition, patients with guttate psoriasis respond to oral treatment with atropine. We wanted to know how the cutaneous cholinergic system could be involved in this process. Since mast cells (MC) are characteristic components of the inflammatory infiltrate of guttate psoriasis, we compared ACh receptor (AChR) composition and ACh production in both epidermis and mast cells of 10 patients with guttate psoriasis in … Show more
