Abstract

The influence of toll-like receptor 4 on neurogenesis and inflammation has been scarcely explored so far by using neuroimaging techniques. For this purpose, we performed magnetic resonance imaging and positron emission tomography with 3'-deoxy-3'-[¹⁸F]fluorothymidine and [¹¹C]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'-[¹⁸F]fluorothymidine and [¹¹C]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.
