Background and aims
The function of interleukin (IL)‐10‐producing B cells (B10 cell) is compromised in patients with allergic diseases. Protease‐activated receptor (PAR)‐2 has immunoregulatory functions. This study aimed to elucidate the role of PAR2 in the suppression of IL‐10 expression in peripheral B cells.
Methods
Peripheral blood B cells were collected from patients with allergic rhinitis...
Background
Aberrant epithelial remodeling with the ectopic expression of p63 (basal cell markers) is an important pathologic phenomenon seen in chronically inflamed airway epithelium such as in nasal polyps (NPs).
Methods
Biopsies were obtained from 55 NP patients and 18 healthy controls (inferior turbinate). Among NP patients, 15 were treated with oral and nasal steroids, so that two sets of NP...
BackgroundChemerin has been implicated to play opposing roles, either pro‐inflammatory or anti‐inflammatory, in various tissue inflammation processes primarily through the regulation of tissue recruitment of immune cells. However, the effect of chemerin in allergic asthma has not yet been explored. We sought to investigate the role of chemerin in the murine model of allergic asthma and explore the...
