Psychodermatology: a molecular link between psoriasis and anxiety disorder

: This article describes premises for the development of psychodermatology. An analysis of research literature and data is presented based on the example of psoriasis and anxiety disorder. Protein molecules with altered concentrations in patients with psoriasis and anxiety disorder compared to controls are identified (chemokine [C-C motif] ligand 2, corticotropin-release hormone, growth hormone 1, leptin, and tumor necrosis factor with increased concentration and brain-derived neurotrophic factor with decreased concentration). All molecules are secretory peptides. In the future, the information obtained may make it possible to pursue an in-depth study of the molecular mechanisms underlying psychodermatology.
