For this purpose, we performed magnetic resonance imaging and positron emission tomography with 3'-deoxy-3'-[(18)F]fluorothymidine and [(11)C]PK11195 at 2, 7, and 14 days following cerebral ischemia in TLR4(+/+)and TLR4(-/-)mice. MRI showed similar infarction volumes in both groups. Despite this, positron emission tomography with 3'-deoxy-3'-[(18)F]fluorothymidine and [(11)C]PK11195 evidenced an increase of neurogenesis and a decrease of inflammation in TLR4(-/-)mice after ischemia. These results evidence the versatility of neuroimaging techniques to monitor the role of toll-like receptor 4 after cerebral ischemia.
