Scientists discover possible solution for Alzheimer’s immunotherapy side effects

Alzheimer’s immunotherapy


A team of researchers from the University of Southampton in England have discovered a potential solution for the side effects caused by immunotherapy treatment for Alzheimer’s.

Alzheimer’s disease is a chronic neurodegenerative disease. The disease starts out slow but progresses with age. Death of nerve cells in the brain causes Alzheimer’s. Symptoms include memory loss, impaired cognitive skills, difficulty speaking and decision-making.

Scientists believe plaques formed by beta-amyloid (pieces of protein) and neurofibrillary tangles in the brain causes the death of brain cells. In the patients with Alzheimer’s, the total size of the brain shrinks, while the tissue have constantly lesser nerve cells and connections.

The older you get, the higher is your risk of getting Alzheimer’s. People over the age of 70 are at a higher risk of developing Alzheimer’s. Around 80% people over the age of 85 are affected by this dreaded disease.

An estimated 46.8 million people globally have dementia and Alzheimer’s is the most common form of dementia.

Around 800,000 people are affected by Alzheimer’s in the UK.


Immunotherapy is a hopeful approach for the treatment of Alzheimer’s. The procedure uses antibodies to prompt the immune system to discard beta-amyloid, which is a hallmark of Alzheimer’s disease.

Although, during test on lab mice, antibodies used against beta-amyloid have successfully cleared plaques and reversed cognitive loss, clinical trials showed side effects that caused inflammation in the brain of Alzheimer’s patients, especially ARIA (amyloid-related imaging abnormalities). ARIA causes small bleeding and threatening brain swelling.

The research team, led by Dr. Jessica Teeling, Associate Professor in Immunology at The Centre for Biological Sciences, engineered 3 antibodies to alter the process by which they engage cells in immune system. They discovered that small, explicit alterations in the anti-amyloid antibodies maintained the immunotherapeutic activity but didn’t have any inflammatory side effects.


Dr. Teeling says it is crucial to learn more from studying these novel interventions and optimize their effects by using antibody engineering.

The findings of the study which was in collaboration with Lundbeck (a multinational pharmaceutical company based in Denmark), underscore the possibility of antibodies to terminate disease-causing plaques and suggest possible future treatments.

The researchers believe that further work should be done to increase potency of the antibody, but without the inflammatory side effects.

These studies give us a roadmap of how to use the advancements of antibody engineering and apply antibody therapeutics targeting various neurodegenerative diseases. In the future, Alzheimer’s drugs will possess new technologies and improvements to clear plaque buildup, while keeping unharmed other areas of the brain, concludes Dr. Stavenhagen of Lundbeck.

  1. My name is Olisa Blessing, I feel so good. I never thought I would be this healthy again in my life. I have worked as an air hostess ( cabin crew ) for 3years but early this year, I lost my job because of this deadly disease called Herpes virus (HSV). I never felt sick or notice any symptoms. Not until the day all workers were asked to bring their doctors report card, that was how I got tested and I found out that I'm HSV positive and that made me lose my job because it was considered as an STD and is an incurable disease. I was so depressed that I started thinking of suicide.
    I explained my situation to an older friend of mine, who often said to me 'a problem shared is a problem half solved. She felt so pity for me that she referred me to Dr. Utu Herbal Cure, that was how I contacted Dr. Utu and got the medication from him and was cured for real.
    I went back to my work a month later with another HSV negative test result and they performed another test to be very sure and they found out I am negative.
    Eventually, the foremost test was replaced with a negative result, and my position was revived with an apology letter and compensation.
    Beware of impersonators,
    Dr. Utu can only be reached at-
