Galvani Bioelectronics is a pioneering effort in bioelectronic medicine, an innovative field merging biology and electronics. It develops new treatments for chronic diseases by using miniature, implantable devices. These devices aim to modify the body’s natural electrical signals, restoring healthy organ and tissue function.
Understanding Bioelectronic Medicine
Bioelectronic medicine explores how tiny, implantable devices interact with the body’s nervous system to treat various conditions. The human body functions through a complex network of electrical signals that coordinate activities between cells, tissues, and organs. When these signals become abnormal, they can contribute to disease. Bioelectronic therapies seek to correct these irregularities by delivering precise electrical pulses to specific nerves, influencing cellular activities and physiological processes.
This approach integrates knowledge from neuroscience, engineering, and immunology to create targeted interventions. Unlike traditional drug therapies, bioelectronic medicine aims for localized and precise modulation of neural pathways. The goal is to restore the body’s natural communication systems, addressing the root causes of dysfunction and promoting healing. This field offers a less invasive alternative to some conventional medical procedures and drug regimens.
How Bioelectronic Devices Work
Bioelectronic devices are small, implantable systems that interface directly with nerves. They contain microchips and sensors that detect irregular electrical signals within the body’s neural networks. Once an abnormal signal is identified, the device delivers targeted electrical impulses to correct it, effectively “reprogramming” the nerve’s activity. This process is similar to a pacemaker, but it modulates signals along nerves that control organ function or immune responses.
The precision of these devices allows for highly specific interventions. For example, some devices target the vagus nerve, which connects the brain to various internal organs like the spleen, liver, and gastrointestinal tract. Stimulating this nerve can influence processes like inflammation. Key components include miniature power sources, advanced sensors to monitor biological signals, and microprocessors to process data and deliver electrical stimulation.
Current and Potential Medical Applications
Bioelectronic medicine treats chronic diseases often difficult to manage with conventional therapies. A prominent research area is rheumatoid arthritis, an autoimmune condition causing joint inflammation. Clinical studies explore splenic nerve stimulation, where an implanted neurostimulator targets the splenic nerve to reprogram immune cells in the spleen, reducing inflammation and pain.
Bioelectronic therapies are also investigated for inflammatory bowel disease, diabetes, and neurological disorders like epilepsy and Parkinson’s disease. Vagus nerve stimulation, for instance, shows potential in suppressing pro-inflammatory cytokines, molecules involved in inflammation. Ongoing clinical trials suggest bioelectronic medicine could offer new treatment options where existing pharmaceutical options fall short.
The Legacy of Luigi Galvani and the Company Galvani Bioelectronics
The field of bioelectricity traces its origins to the 18th century, largely due to Italian physician Luigi Galvani. Around 1780, Galvani demonstrated that electrical sparks caused muscle contractions in a frog’s leg. He observed muscles contracting even without an external electrical source when connected by two different metals, leading him to propose “animal electricity” in living tissues. Galvani’s discoveries were foundational, shifting scientific understanding to recognizing nerves as electrical conductors, laying the groundwork for neurophysiology.
This historical legacy inspired the naming of Galvani Bioelectronics. The company formed in 2016 as a joint venture between GlaxoSmithKline (GSK) and Verily Life Sciences, a subsidiary of Alphabet Inc. This collaboration combines GSK’s expertise in drug discovery with Verily’s technical capabilities in miniaturized electronics, device development, and data analytics. A joint investment of up to £540 million (approximately $715 million) over seven years supports developing bioelectronic medicines, with initial efforts focused on inflammatory, metabolic, and endocrine disorders like type 2 diabetes.
