# Reprogramming immunity: Code that could save us | Gordon Broderick | TEDxUniversityofSaskatchewan Source: https://www.youtube.com/watch?v=bYrtKc_TP1U Recap page: https://rapidrecap.app/video/bYrtKc_TP1U Generated: 2026-02-10T22:03:17.987+00:00 --- ## Quick Overview Gordon Broderick and his team developed a rudimentary digital twin of the immune system by compiling decades of research and coding, which allowed them to simulate autoimmune and persistent conditions like Gulf War illness, ultimately finding that a sequential two-drug treatment—an anti-inflammatory followed by a hormone regulator—rescued up to 70% of simulated patients. **Key Points:** - The speaker, inspired by the Apollo 8 mission's precise navigation, wondered if his own overreacting immune system had a control computer that could be reprogrammed. - Scientists like Stuart Kaufman and Eric Davidson developed the concept of the cell's control circuitry and coined the term 'genomic computer' for DNA, attracting engineers to biology. - Transplant biologist Charlie Oros proposed that the millions of coordinating immune cells form a sophisticated 'thinking machine' that runs programs like 'Fight infection' but sometimes runs the wrong program, causing autoimmune illnesses. - In patient studies involving maximum-capacity exercise, researchers observed repair signals firing persistently long after recovery, indicating the immune system was 'stuck in survival mode' without fading inflammation. - Building a digital twin of the immune system by mining tens of thousands of research papers allowed the team to reproduce molecular signatures seen in sick patients after exposure to a 'digital virus' or chemicals. - Testing thousands of FDA-approved drugs on the digital twin showed no single drug worked, but combining an anti-inflammatory followed by a hormone regulator in the correct sequence rescued up to 70% of digital patients. - The digital twin's predicted sequence was validated when it successfully recovered a mouse model reproducing decades-long persistent symptoms seen in Gulf War veterans, leading to human trials. **Context:** The presentation begins with Gordon Broderick recalling watching the Apollo 8 mission in 1968, which contrasted sharply with his own experience of having an immune system that overreacted severely to everyday stimuli, prompting him to question if the body had a control computer like the spacecraft. This curiosity aligns with a broader scientific movement where engineers began applying control circuitry concepts to biology, leading to the idea that the immune system acts as a complex, coordinated computer capable of running programs to fight infection or heal wounds. ## Detailed Analysis Gordon Broderick explores the concept of reprogramming the immune system by framing it as a sophisticated control computer, similar to the navigation systems required for space travel. He details how autoimmune illnesses, like lupus, and persistent conditions like long COVID or Gulf War illness symptoms, represent the immune system running the wrong program or getting 'stuck' in an emergency response, akin to a computer freezing or showing a blue screen of death. Using advanced tools like flowcytometers, the team analyzed patients recovering from exertion and found immune signals stuck in overdrive. To find a fix, they built a rudimentary digital twin of the immune system by coding knowledge from tens of thousands of research papers. This digital model successfully replicated the molecular signatures of sick patients. When testing drug combinations on this twin, they discovered that no single drug was effective; however, applying an anti-inflammatory drug followed precisely by a hormone regulator drug reset the system, rescuing up to 70% of digital patients. This sequence was successfully validated in an animal model mimicking decades-long persistent symptoms from the Gulf War, leading to human trials and offering hope to marginalized patient families. The future involves building more lifelike twins using AI and quantum computing to deliver personalized 'molecular recipes' as updates to the body's immune operating system. ### Inspiration and Core Concept - Apollo 8 awe sparked inquiry into body's control computer - Early concepts coined 'genomic computer' by Eric Davidson - Immune system viewed as a 'thinking machine' of coordinated cells ### Immune Malfunction Manifestation - Autoimmune illnesses occur when the immune system 'mistakes friend for foe' - One in 15 men and one in three women develop autoimmune illness - Persistent conditions like long COVID show the immune system stuck in limbo ### Investigative Findings - Exercise challenge revealed repair signals firing persistently long after recovery - Researchers observed inflammation did not fade, suggesting a 'survival mode' on repeat ### Digital Twin Development - Researchers gathered data on immune cell behavior for over a decade - Code was written and pushed to large computers to build a rudimentary digital twin of the immune system ### Simulation and Drug Testing - Digital twins replicated patient sickness when exposed to 'digital virus' or chemicals - Testing thousands of drugs individually failed, but a two-drug sequence succeeded in rescuing up to 70% of digital patients ### Successful Treatment Protocol - The effective sequence involved applying an anti-inflammatory first to calm the body, followed by a hormone regulator to reset the system ### Validation and Future Vision - The digital twin's predicted sequence recovered a mouse model replicating Gulf War veteran symptoms - Future work involves building more lifelike twins using AI and quantum computers to deliver personalized molecular recipes
