A structurally normal mitral valve when abnormally tethered in a dilated ventricle will startto leak once the available closing force becomes insufficient to achieve effective systolic leaflet coaptation (1). Conversely, diastolic tethering may restrict leaflet mobility and thus limit complete openi mai mult

Abstract

Background

Interleukin 33 (IL-33) is implicated as an epithelium-derived danger signal promoting Th2-dependent responses in asthma. We hypothesized that IL-33 might also have direct effects on mast cell-driven allergic airway obstruction.

Methods

The effects of IL-33 on allergic responses in
