| Research Abstract |
This study was aimed to examine a possible role of secretory PLA2receptor in the pathogenesis of cardiovascular diseases and to develop a new drug forprevention from cardiovascular diseases. As a result, (1) PLA2R－/－mice had a higherprevalence of cardiac rupture after MI compared with the PLA2R+/+mice. PLA2R－/－mice hada low content of collagen and a reduction in the number of myofibroblasts and theexpression of profibrogenic molecules in the infarct region. (2) The ovalbumin(OVA)-induced airway inflammation, characterized by an increased number of eosinophilsand neutrophils in BAL fluid and inflammatory histological changes in airway, was strongerin PLA2R－/－mice than in PLA2R+/+mice.
