Internal Exploration and Treatment of the Gut Made Possible by New Intelligent Pill
A groundbreaking technology has been developed that could revolutionise the treatment of not only inflammatory bowel diseases (IBD), but also conditions linked to gut health, such as type 2 diabetes, heart disease, and chronic fatigue. The innovative technology involves genetically engineering gut bacteria, specifically a probiotic strain of Escherichia coli, to be light-responsive and capable of both detecting disease signals and producing therapeutic molecules inside the gut.
The technology uses a swallowable optoelectronic capsule controlled via a smartphone app. This capsule communicates with the bacteria through light signals. When the capsule detects inflammatory markers such as nitrate—produced during gut inflammation—it senses bioluminescence emitted by the engineered bacteria and transmits this to clinicians via Bluetooth. On command from the app, the capsule emits specific light (e.g., green LED) that activates the bacteria’s light-sensitive genetic circuits to produce therapies such as anti-inflammatory nanobodies, mimicking drugs used to treat IBD.
This innovative bidirectional communication enables real-time diagnosis and targeted treatment directly within the gut. The technology has been demonstrated in preclinical studies involving pigs with colitis, a model of IBD, where it allowed detection of inflammation and delivery of anti-TNF nanobody therapies that reduced inflammation.
The core components of this precision medicine platform include genetically engineered E. coli that detect inflammation markers and emit light signals, an ingestible capsule equipped with sensors, LEDs, a photomultiplier tube, and Bluetooth, and a smartphone app to monitor signals and trigger bacterial therapeutic production.
While the technology holds immense promise, it is important to note that it is still in the early stages of development. Before it can be used in humans, further research will need to evaluate the general safety of this technology and answer some important questions, such as how these engineered microbes affect the natural balance of other bacteria living in the gut.
The study was led by senior author Hanjie Wang from Tianjin University in China. The researchers expressed excitement about the technological development, with Dr Lindsey Edwards, senior lecturer in microbiology at King's College London, and Dr Nicholas Ilott, senior researcher and lead bioinformatician for the Oxford Centre for Microbiome Studies, both expressing their enthusiasm. However, Dr Alexandre Almeida, from the Department of Veterinary Medicine at the University of Cambridge, expressed concerns about the technology being a long way off from human use.
Despite these concerns, the technology could potentially be part of a new generation of therapies for a variety of diseases, including those currently difficult to treat. The flexibility of the system suggests it could potentially address various diseases by harnessing engineered gut microbes to sense different biomarkers and release therapeutic agents on demand.
In conclusion, this innovative technology represents a significant step forward in the field of precision medicine, offering the potential for real-time diagnosis and targeted treatment of gut-related conditions. While further research is required, the technology holds great promise for the future of medicine.
