Initial Praise for The Secret Language of Cells

The Secret Language of Cells

The Secret Language of Cells takes us on an exciting journey into a world where we can visualize elaborate conversations among immune cells, brain cells, gut cells, bacteria, and even viruses. Dr. Lieff gives a wealth of examples for his thesis that this cellular signaling is the basis of life. It is a must read for anyone seeking to understand modern biology and advanced medical science. It is equally important for those of us who wonder, as I do, how this ubiquitous information transfer in the form of cellular conversations might be related to the emergence of intelligence and consciousness.

– Ray Kurzweil, Inventor, author and futurist

The Secret Language of Cells explains the complex ways that cells in the body communicate and presents a new paradigm for understanding health and disease. It also suggests new possibilities for treatment and for promoting healing.  I’m pleased that my former Harvard colleague, Jon Lieff, has written this important book.

Through a brilliant synthesis of cellular biology, microbiology, immunology and neuroscience, The Secret Language of Cells offers a lucid explanation of the marvelous intricacies of cellular life. The result is a masterful exploration of the profound implications of cellular intelligence for understanding pathophysiology, human health and even our origins.

 – William B. Miller, Jr., MD, physician, biologist, author of The Microcosm Within: Evolution and Extinction in the Hologenome, and internationally recognized expert on Cognition-Based Evolution


Jon Lieff’s description of cellular communication is insightful, provocative, illuminating, and engaging and provides deep and novel observations into the remarkable symphony of how life happens.  Mimicking the cellular world he describes, Dr. Lieff is the great communicator and muse of living things.   An inspiring and informative read.

– Ted Kaptchuk, Professsor of Medicine, Harvard Medical School 


This journey into the dynamic realm of cellular conversations is a tour-de-force – fascinating, vital, and especially timely for understanding emerging viruses. As we learn about intelligence in smaller and smaller animals, it’s not surprising that the tiniest creatures – microbes and even viruses – exhibit elaborate communication and complex decision making. Read The Secret Language of Cells!

As a storyteller, my imagination is sparked by the insights Dr. Lieff brings to our innermost world and the mysteries at the edge of our understanding. The Secret Language of Cells reveals how the micro world reflects the macro, alive with heroes and villains, shapeshifters and tricksters, vigilant guards and gullible bystanders, helpers that commit suicide for the common good and warriors that seize the day or collapse from exhaustion. Lieff’s fascinating exploration inspires awe for the astonishing dialogues and clarion calls at the heart of the intelligence within.

– Antonia Felix, Ed.D., MFA, New York Times bestselling author


The Secret Language of Cells is ideal for the education of medical and science students, as well as for practicing physicians. Dr. Lieff’s remarkable synthesis of the scientific literature provides a current view of the intricate communication systems determining our physiology. He clearly explains how conversations among cells are the bridge between immunology, neuroscience, microbiology, and cancer research. Detailed Endnotes provide an avenue for further study, either on one’s own or as part of a formal course.
