摘要
The involvement of cytosolic phospholipase A(2) (cPLA(2)) in apoptosis of adult mouse superior cervical and dorsal root ganglia neurons has been investigated by the use of immunohistochemistry for cPLA(2) and DNA nick-end labelling for apoptotic cells, respectively. cPLA(2) immunoreactivity was strongly upregulated in neurons of both preparations during in vitro culturing. By double labeling it was unequivocally demonstrated that cPLA(2) was present and upregulated only in neurons undergoing apoptosis. A similar picture emerged when cPLA(2) immunoreactivity was compared with staining with Fluoro-Jade, a novel fluorochrome marker for neuronal degeneration. The preferential presence of cPLA(2) in apoptotic and degenerating cells suggests that the enzyme is important for some mechanism involved in or intimately coupled to neuronal cell death.
