Task: Intent Identification
Input (English): Neuropeptides (NPs) may play an important role in the pathogenesis of atopic dermatitis (AD) by regulating immune responses and contributing to the cross-talk between the immune and nervous systems.', 'To assess the ability of NPs to influence interleukin (IL)-13 and interferon (IFN)-gamma production and the expression of the activation marker HLA-DR in skin memory T cells [cutaneous lymphocyte-associated antigen (CLA)+ T cells] from patients with AD with severe, chronic lesions and intense pruritus, and from nonatopic controls.', 'Cells were cultured in the presence and absence of different NPs, calcitonin gene-related peptide (CGRP), somatostatin (SOM) and substance P (SP). IL-13 and IFN-gamma production and HLA-DR expression were measured in both CLA+ and CLA- T-cell subsets by flow cytometry.', 'CGRP increased IL-13 production in peripheral blood mononuclear cells from patients with AD (P < 0.05), with no changes detected in the presence of SOM or SP. These patients with AD had a lower expression of CGRP receptor compared with controls (P < 0.05). Memory T cells incubated with CGRP also showed an increase in IL-13 (P < 0.05) and HLA-DR (P < 0.05) in CLA+ T cells from patients with AD compared with controls, but not in CLA- T cells. Patients with a higher production of IL-13 were those with higher total IgE and percentage of skin area involved. Furthermore, the IL-13/IFN-gamma ratio was increased in patients with AD after cells were cultured with CGRP (P < 0.05).
