Abstract

In this issue, Chadarevian et al. showed that engraftment of human iPSC-derived microglia (iMG) engineered to express secreted neprilysin (sNEP) under the plaque-responsive CD9 promoter reduces amyloid burden, neuronal damage, and inflammation in an Alzheimer's disease (AD) mouse model.<sup>1</sup> These findings establish a cell-based strategy to treat neurological diseases.
