Comment from academist staff
Treating incurable neurological disease with ultra-small bubbles

Makoto Ebis

Dr Kida who is a neurologist has been treating various neurological disordered patients in everyday practice as well as looking for new therapeutic approaches in research labs. Recently, Dr Kida has come up with a completely new idea of using “ultrafine bubbles “, which is an extremely small bubbles, to treat Alzheimer’s disease. This method utilizes the mysterious nature of ultrasound fine bubbles which is completely different from microbubbles. Let’s take a look at Dr Kida’s challenge in treating Alzheimer’s disease.

Bursting “invisible” bubbles by ultrasound

You will experience “bubbles” in everyday life one way or another. For example when you wash your hands with soap or bubbles in a champagne glass, or when you boil water and bubbles pop up on the surface. “Ultrafine bubbles” are no match with these bubbles when considering the size of them. If you can imagine ordinary 2-3mm bubbles as the size of the Tokyo Dome Stadium (244m diameter), “ultrafine bubbles” are the size of marbles. They are invisible to any known optical high power magnifying microscopes.

Ultrafine bubbles have several unexplained physical characters that ordinary bubbles don’t have. For example, ultrafine bubbles exists in water for very long periods where as ordinary bubbles simply float up to the surface and disappear in minutes. These ultra-small bubbles can be stable in water for days, weeks or even months. The liquid containing the bubble is usually transparent but if you expose it to a laser pointer, the ultrafine bubbles reflects and sparkles and become visible.

Furthermore, if you expose ultrasound (high frequency inaudible sound waves) to the bubbles, they start to osculating as they expand and shrink and eventually collapse. This phenomenon is generally called “cavitation”.

The magic bullet that carries genes

Containing or persevering small gas pockets within water or blood for long periods, or collapsing them with ultrasound is a new technology that can easily be applied to revolutionary drug delivery treatment. We have been studying ways to observe ultrafine bubbles for quite a while and searched for ways to apply this unique character to medical use.

As I am a neurologist and see various neurological disorders in everyday practice, I eventually came up with the idea of using ultrafine bubbles for gene therapy. Physical or mechanical energy is often used to “inject” genes into cells. It was quite obvious that from my previous microbubble observations that combining ultrasound and ultrafine bubbles was the answer to efficiently deliver therapeutic materials or genes into the neural cells. Ultrafine bubbles can puncture very very small holes on the cell surface thus resulting in a revolutionary “drug delivery system (DDS)” method. To make it simple, ultrafine bubbles was the magic bullet to carry and deliver genes into living neural cell.

Genes can become a template for producing proteins. Once they are inserted into the cells, they exists for prolonged periods of time. If it were possible to inject a therapeutic protein producing gene template strand into neural cells, it would open up a possibility of curing disordered neural conditions. In our initial experiments, we added ultrafine bubbles in cultured mice cells and observed if gene therapy was possible. As a result, we succeeded in injecting green fluorescent protein producing genes into neural cells only when ultrafine bubbles were bursted by ultrasound energy. The safety and efficacy was reported in a journal.

Ultrafine bubbles as a means to cure Alzheimer’s disease

We are currently in the process of developing a new cure for Alzheimer’s disease with ultrafine bubbles. Alzheimer’s disease (Alzheimer-type dementia) is a slow progressive disease which deprives your memory and induces disorientation. As the disease advances, you may not be able to recognize your family’s face or start having problem talking or accomplishing everyday tasks. This disease has become a social problem all over the world especially in Japan due to its aging society.

A pathogenic protein called “amyloid beta peptide” or “tau protein” accumulates within the brain in Alzheimer’s disease patients. These proteins are like waste products that affect the function of the neurons results in learning or memory disfunction and finally disrupts the neural network of the brain.

Currently, researchers around the world are trying to develop a gene therapy drug for Alzheimer’s disease. There are several ways to combat this disease but one of them is to deliver a gene that produces a special proteolytic enzyme which eliminates amyloid beta within the brain. This gene could delay the progression of Alzheimer’s disease.

We are now trying to efficiently deliver this gene to neural cells within the brain by ultrafine bubbles. The biggest challenge is to to see if we can carry the gene with ultrafine bubbles and collapse it by ultrasound energy at the right time and place, in this case the neural cells in the brain. If we are successful, we should see improvement of memory and learning in Alzheimer sickened mice. More specifically, the plan is to deliver proteolytic enzyme producing genes into the brain and monitor the behavioral rating, count the number of improved neural cell (pathological analysis). The data obtained will contribute greatly to future clinical trials.

Supporting my research project

As a neurologist, I have diagnosed various difficult to cure patients such as dementia and understand the suffering of the families. My experience with them is my major drive in developing a solution that can reverse the progress of these diseases. I was luck to have met this new technology of using ultrafine bubbles. My current belief is that this technology can be used as the ultimate means to carry drugs to the target location and sufficiently inject them into the cells by ultrasound energy.

The financial support from you will be used to purchase ultrafine bubble generators, fee to design and replicate the genes, culture cells and animals. The remaining will be used to hire technicians. I am confident that your support will lead to the success of this project to find a cure for Alzheimer’s disease.

Profile

Hiroshi Kida

I was brought up in rural Nagasaki area were there was a lot of greenery. After graduating from medical school, I have worked in hospitals as a neurologist. My interest in basic science and gene therapy research began in my graduate school days.I see many possibilities in the use of ultrafine bubbles as not much is know about its physical and chemical characteristics. Intractable disease remains an unmet challenge and I believe that ultrafine bubbles is the answer to many of the obstacles set forth in realizing a real cure for them. The present situation is often a dead end therapy where nothing can be done to stop or slow down the progression of the disease. Despite this, the many “thank you”s from these patient have been my motivation to structure a better future for medicine. Ultrafine bubbles may just be the Panacea for Alzheimer’s and other neurological diseases. I await your support for this exciting project!
