The Parkinson's disease (PD)-associated gene DJ-1 mediates direct neuroprotection. The up-regulation of DJ-1 in reactive astrocytes also suggests a role in glia. Here we show that DJ-1 regulates proinflammatory responses in mouse astrocyte-rich primary cultures. When treated with a Toll-like receptor 4 agonist, the bacterial endotoxin lipopolysaccharide (LPS), Dj-1-knockout astrocytes generated >10 times more nitric oxide (NO) than littermate controls. Lentiviral reintroduction of DJ-1 restored… CONTINUE READING
