Effect of overnight smoking abstinence on a marker for microglial activation: a CDAA1106 positron emission tomography study.

Microglia are the main immune cells in the central nervous system and participate in neuroinflammation. When activated, microglia express increased levels of the translocator protein 18 kDa (TSPO), thereby making TSPO availability a marker for neuroinflammation. Using positron emission tomography (PET) scanning, our group recently demonstrated that smokers in the satiated state had 16.8% less binding of the radiotracer [C]DAA1106 (a radioligand for TSPO) in the brain than nonsmokers.
