A page-turning story of scientific detective work and thrilling medical potential, The Angel and the Assassin illuminates the newly-understood role of microglia—an elusive type of brain cell that is vitally relevant to our everyday lives.

Until recently, microglia were thought to be helpful but rather boring housekeeper brain cells. But a recent groundbreaking discovery has revealed that they connect our physical and mental health in surprising ways. When triggered—and anything that stirs up the immune system can activate microglia, including chronic stressors, trauma, and viral infections—they can contribute to memory problems, anxiety, depression, and Alzheimer’s. Under the right circumstances, however, microglia can be coaxed back into being angelic healers, able to repair the brain in ways that help alleviate symptoms and hold the promise to one day prevent disease.

A fascinating behind-the-scenes account of this cutting-edge science, The Angel and the Assassin also explores the implications of these game-changing discoveries for helping those who are suffering to find new pathways to healing. Award-winning journalist Donna Jackson Nakazawa illuminates this newly understood science, following practitioners and patients on the front lines of treatments, and witnesses patients finding significant relief from pressing symptoms, and at least one stunning recovery, offering new hope to the tens of millions who suffer from mental, cognitive, and physical health issues.

Hailed as “riveting,” “stunning,” and “visionary” The Angel and the Assassin offers us a radically reconceived picture of human health and promises to change everything we thought we knew about how to heal ourselves.
