Abstract
Background: Atopic dermatitis (AD) is a chronic, inflammatory, often severely itching skin disorder. It may worsen due to stress, depression, or anxiety. Calcitonin gene-related peptide (CGRP) may be involved in inflammation signaling. CGRP has also been suggested in relation to stress, depression, and anxiety. This study aimed to investigate the expression of CGRP in the skin of patients with AD.
Methods: Twenty-seven adult patients with AD, characterized with clinical and psychodemographic parameters, were investigated regarding CGRP expression in skin biopsies, using an immunohistochemical technique.
Results: The total number of CGRP-positive nerve-like fibers was found to be higher in lesional skin than in non-lesional skin. Moreover, more inflammatory cells of dendritic shape intruded into the epidermis in lesional skin compared to non-lesional skin. Keratinocytes showing expression of CGRP were also found in lesional skin. Interestingly, the number of CGRP-positive nerve-like fibers in lesional skin correlated with depressive and anxiety scores. Correlation with depressive score was also found for round CGRP-positive inflammatory cells in the epidermis.
Conclusions: CGRP may have a role in both the inflammatory process and distress, in AD.
期刊介绍：
The journal Immunopharmacology and Immunotoxicology is devoted to pre-clinical and clinical drug discovery and development targeting the immune system. Research related to the immunoregulatory effects of various compounds, including small-molecule drugs and biologics, on immunocompetent cells and immune responses, as well as the immunotoxicity exerted by xenobiotics and drugs. Only research that describe the mechanisms of specific compounds (not extracts) is of interest to the journal.
The journal will prioritise preclinical and clinical studies on immunotherapy of disorders such as chronic inflammation, allergy, autoimmunity, cancer etc. The effects of small-drugs, vaccines and biologics against central immunological targets as well as cell-based therapy, including dendritic cell therapy, T cell adoptive transfer and stem cell therapy, are topics of particular interest. Publications pointing towards potential new drug targets within the immune system or novel technology for immunopharmacological drug development are also welcome.
With an immunoscience focus on drug development, immunotherapy and toxicology, the journal will cover areas such as infection, allergy, inflammation, tumor immunology, degenerative disorders, immunodeficiencies, neurology, atherosclerosis and more.
Immunopharmacology and Immunotoxicology will accept original manuscripts, brief communications, commentaries, mini-reviews, reviews, clinical trials and clinical cases, on the condition that the results reported are based on original, clinical, or basic research that has not been published elsewhere in any journal in any language (except in abstract form relating to paper communicated to scientific meetings and symposiums).
