IL-17A induces chromatin remodeling promoting IL-8 and TSLP release in bronchial epithelial cells. Effect of Tiotropium.

Interleukin-17A promotes the growth of human germinal center derived non-Hodgkin B cell lymphoma

2015

Interleukin (IL)-17A belongs to IL-17 superfamily and binds the heterodimeric IL-17 receptor (R)(IL-17RA/IL-17RC). IL-17A promotes germinal center (GC) formation in mouse models of autoimmune or infectious diseases, but the role of IL-17A/IL-17AR complex in human neoplastic GC is unknown. In this study, we investigated expression and function of IL-17A/IL-17AR in the microenvironments of 44 B cell non-Hodgkin lymphomas (B-NHL) of GC origin (15 follicular lymphomas, 17 diffuse large B cells lymphomas and 12 Burkitt lymphomas) and 12 human tonsil GC. Furthermore, we investigated the role of IL-17A in two in vivo models of GC B cell lymphoma, generated by s.c. injection of SU-DHL-4 and OCI-Ly8…

IL-17A induces chromatin remodeling promoting IL-8 release in bronchial epithelial cells: Effect of Tiotropium

2016

Abstract Aims IL-17A plays a key role in the persistence of airway inflammation, oxidative stress, and reduction of steroid-sensitivity in COPD. We studied the effect of IL-17A on chromatin remodeling and IL-8 production. Main methods We measured the levels of IL-8 and IL-17A in induced sputum supernatants (ISS) from healthy controls (HCs), healthy smokers (HSs), and COPD patients by enzyme-linked immunosorbent assay (ELISA). A human bronchial epithelial cell line (16HBE) was stimulated with ISS from HCs, HSs, or COPD subjects. IL-8 was evaluated in 16HBE by Western blot and real-time polymerase chain reaction (PCR). Histone deacetylase 2 (HDAC2), acetyl histone H3 (Ac-His H3) (k9) and inhi…
