About this item
Your cells are talking about you.
Right now, both your inner and outer worlds are abuzz with chatter among living cells of every possible kind - from those in your body and brain to those in the environment around you. From electrical alerts to chemical codes, the greatest secret of modern biology, hiding in plain sight, is that all of life’s activity boils down to one thing: conversation.
While cells are commonly considered the building block of living things, it is actually the communication between cells that brings us to life, controlling our bodies and brains, determining whether we are healthy or sick, and directly influencing how we think, feel, and behave.
In The Secret Language of Cells, doctor and neuroscientist Jon Lieff lets us listen in on these conversations, and reveals their significance for everything from mental health to cancer. He explains the surprising science of how very different cells - bacteria and brain cells, blood cells and viruses - all speak the same language. This overarching principle has been long overlooked because scientific journals use impenetrable jargon that makes it hard to be understood across disciplines, much less by the general public.
Lieff presents a fascinating and accessible look into cellular communication science - a groundbreaking and comprehensive exploration of this biological phenomenon. In these pages, discover the intriguing lives of cells as they ask questions, get answers, give feedback, gather information, call for each other, and make complex decisions. During infections, immune T-cells tell brain cells that we should “feel sick” and lie down. Cancer cells warn their community about immune and microbe attacks. Gut cells talk with microbes to determine which are friends and which are enemies, and microbes talk with each other and with much more complicated human cells in ways that determine which medicines work and which will fail.
With applications for immunity, chronic pain, weight loss, depression, cancer treatment, and virtually every aspect of health and biology, cellular communication is revolutionizing our understanding not just of disease, but of life itself. The Secret Language of Cells is required listening for anyone interested in following the conversation.

I looked forward to his book and expected something similar. My first reading gave a surprise. Jon has concentrated on producing a book that anyone can read. It is clear and uses straightforward language. It is very well organised. He gives a quite different synthesis to other writers in the general field, although I suspect he owns the field himself. There are so many interesting areas that get a distinctly new approach. See below his section on COV-19. I got more from these few paragraphs than from whole articles:
"THE NOVEL CORONAVIRUS—VERY CAPABLE WITH FIFTEEN GENES The novel coronavirus (technically called SARS-CoV-2), the virus that causes the illness COVID-19, has great capabilities, with fifteen genes that produce at least twenty-nine proteins. One very large protein is actually sixteen different ones that are cut and released by other proteins. Several of these proteins produce a bubble filled with fluid where the virus builds a factory to produce more viruses. Inside the bubble, two proteins produce new RNA, and another brings material to build the RNA; a medicine for SARS can attack this step. Three other proteins unwind the RNA to make it useful, correct errors, and cut up leftover RNA to keep the host cell from reacting to it. Other proteins alter the human cell’s environment to help the virus survive in the cell and escape. Still others block immune signals to other cells, influence the flow of molecules in and out of the cell nucleus, and turn human genes on and off. Others poke holes in the cell’s membrane, making escape easier, and disable a protein on the surface of human cells trying to grab the escaping virus. One stimulates inflammation and another induces human cells to commit suicide. Four of SARS-CoV-2’s proteins build the structure that has been seen so frequently in the media. All four help with assembly and release from the host cell. One protects the RNA deep inside. Another produces the famous spikes that make it appear as a crown, also known as a corona. These spikes attach to the human cell receptor ACE2 molecule in the airways and other places. This molecule is also an important enzyme blocked by a class of blood pressure medications (ACE inhibitors), likely causing an association of increased risk of COVID-19 symptoms in those who have high blood pressure. Attaching to this receptor allows the virus to enter into cells and creates a strong attachment that causes the symptoms to linger. Of all the proteins, this one might be the one that causes the COVID-19 virus to be so dangerous to humans, since it attaches so firmly to human cells.

The main text does not have any references which some may regret. But the extensive list by chapter given at the end of the book more than makes up for this.
This review is based on my first fly-through of the text. Below is another snippet from the latter part of the book that give a good idea of where it ends up.
"WHAT CONCLUSIONS CAN BE DRAWN from this tour of cellular conversations? Although cells are considered the most basic characteristic that defines life, it is actually the conversations among cells, and also the conversations that take place inside them, that determine biological activity and produce the essence of life. The science of cell communication allows new ways to understand health and disease. It also has implications for understanding evolution as well as consciousness. While elaborate signals among neurons have been observed for years, why hasn’t signaling among all other cells been obvious before now? It has been hidden from general view because of impenetrable jargon in scientific journals. Arcane terminologies of signals, receptors, genes, and cell subtypes aren’t generally known, even across various research areas. Professional articles and books on molecular signaling are complex and don’t provide this overarching synthesis. They are hard to understand, even for clinicians and scientists who don’t actively work in a particular field. Also, most of this information has been discovered in the past several years, and biology dogmas die hard. The synthesis of scientific data in this book makes it easy to see why communication among cells has wide-ranging significance. Descriptions of cellular conversations help demystify the latest research on immunity, digestion, cancer, neuroscience, pain, and other topics. This overview—not available anywhere else in one place—is particularly important for those who are ill and trying to follow advanced treatments."

I just hope that Jon is sketching the outline for his next book!
