Glial cells high levels

The A3AR is expressed in relatively high densities in lung, liver, neutrophils, macrophages, and glial cells. In the heart and brain, there are distinct effects on cell survival, but the A3AR is expressed at a much lower level. Its presence on neurons in the central nervous system was controversial, but now well established (Lopes et al. 2003 Yaar et al. 2002).
