The Shark Immune System

di Leah Marston (Autore)

Leah Marston, 2026

The oldest immune system on Earth is still swimming — and it is not the miracle you were sold. You have probably heard that sharks don't get cancer. It is not true. Sharks get tumors, infections, and parasites, just as other animals do — and the supplement industry built on that myth has cost both patients and sharks dearly. But underneath the myth sits a stranger, better story. Sharks are the oldest living jawed vertebrates with an antibody-based immune system, carrying defenses roughly 450 million years in the making: an antibody found nowhere else on Earth, skin whose bacterial community holds steady even around open wounds, and a molecule, squalamine, that fights viruses in a way no other known compound does. The Shark Immune System tells that story with the evidence graded honestly at every step. What is measured is named as measured. What is only promising is named as promising. And what is marketing is named as marketing. Inside you'll discover IgNAR and VNAR — the heavy-chain-only shark antibody, and why drug researchers want the smallest binding domain in immunology How shark wounds close in the wild — the tagging studies, the skin microbiome that refuses to break, and where the healing legend outruns the data The cancer myth, dismantled — the 1992 bestseller, the tumor record going back to 1908, the failed cartilage trials, and the honest unknown about how rare shark cancer really is Squalamine — the dogfish molecule of 1993, its unusual antiviral mechanism, and its long, unfinished road through human trials The great white genome clue — DNA-repair genes under selection, and why a clue is not a cure Why roughly a third of sharks and rays are now threatened — and why every species lost is a medical library burned unread Who this book is for Shark lovers who want the real science behind the legends; health-curious readers who have met the shark-cartilage pitch and want to know what holds up; and anyone who enjoys watching a good myth taken apart carefully, fact by fact. Leah Marston writes popular science about the ocean's oldest survivors, with a simple rule: the wonder has to survive the evidence. The library is still open. This is the tour.
