Clinical Utility of Central and Peripheral Airway Nitric Oxide in Aging Patients with Stable and Acute Exacerbated Chronic Obstructive Pulmonary Disease.

Purpose: Exhaled nitric oxide has been used as a marker of airway inflammation. The NO concentration in the central and peripheral airway/alveolar can be measured by a slow and fast exhalation flow rate to evaluate inflammation in different divisions within the respiratory tract. We hypothesized that FeNO (exhaled NO at a flow rate of 200mL/s) could be used as an evaluation tool for peripheral airway/alveolar inflammation and corticosteroid therapy in chronic obstructive pulmonary disease (COPD) patients.

Indirubin attenuates IL-17A-induced CCL20 expression and production in keratinocytes through repressing TAK1 signaling pathway.

Psoriatic skin inflammation is mainly driven by complex interactions of infiltrating immune cells and activated keratinocytes. Keratinocytes play an active role in initiating and maintenance of psoriatic skin inflammation by secreting chemokines and cytokines. IL-17A produced by T cells potently upregulates the production of chemokine CCL20 in the keratinocytes, which further chemoattracts IL-17A-producing CCR6+ immune cells to the site of inflammation.
