Prof. Hölscher’s research is focused on the development of novel treatments for Alzheimer’s and Parkinson’s disease. His group is currently analysing promising drug candidates that show good neuroprotective effects.
Alzheimer’s and Parkinson’s disease are sporadic diseases, which means there is no clear genetic link to the development in the majority of cases. This makes it difficult to investigate this disease, as very little is known about the mechanisms that trigger the progressive neurodegeneration.
However, there are several risk factors that increase the risk of developing these diseases. Those risk factors can give us some pointers of what mechanisms might be responsible for the initiation of the disease.
One such risk factor is type 2 diabetes. Several studies show that people with diabetes have an increased risk of developing Alzheimer’s or Parkinson’s disease. In diabetes, the hormone insulin loses its effectiveness. Studies of the brain tissue of patients with Alzheimer’s or Parkinson’s disease have shown that insulin signaling is impaired. Insulin not only controls the blood sugar levels, but acts as a growth factor to promote cell growth and repair. It is possible that the lack of the insulin effect reduces the repair mechanisms and puts neurons at risk. Neurons cannot be replaced and live as long as we live. Over years, cellular stress could damage neurons and prepares the ground for the development of Alzheimer’s and Parkinson’s disease.
Novel treatments for Alzheimer’s and Parkinson’s disease
When testing drugs that originally have been developed to treat type 2 diabetes, several showed good effects in preclinical studies of neurodegeneration. When analysing the biochemical processes that underlie Alzheimer’s and Parkinson’s disease, we found that drugs that activate the GLP-1 growth factor receptor in the brain showed good neuroprotective effects.
In preclinical studies we could show that the drugs induce cellular repair mechanisms and prevent the loss of synapses and of synaptic function. The amount of beta-amyloid, a classic biomarker for Alzheimer’s disease, has also been reduced. Importantly, the chronic inflammation response in the brain has been much reduced. Neurons that were not working properly anymore started to come back and function normally again. These observations give us hope that we can actually stop the development of Alzheimer’s and Parkinson’s disease. First clinical trials have shown good effects and show that the drugs also work in humans.
For a review, see Hölscher 2020
Based on our results, a clinical trial testing the effects of liraglutide in patients with Alzheimer’s disease has been conducted in collaboration with Imperial College London. The results have been presented at the AD/PD conference on 9 March 2021. Liraglutide was able to improve memory and cognition in the ADASexec test battery. In addition, brain shrinkage due to neuronal loss and loss of total grey matter was reduced by the drug as shown in MRI brain scans. A paper with the full results will be published soon. The company Novo Nordisk has announced that they want to test the GLP-1 analogue semaglutide in patients with Alzheimer’s disease in two phase III trials.
Further studies of such drugs in Parkinson’s disease are onging. A recent phase II placebo controlled trial conducted at UCL in London has shown very good effects in protecting patients from the disease. This study tested the older drug from this class called exenatide, and an additional trial is starting at UCL to add vital information to the clinical effects of exenatide. Other clinical trials testing newer drugs are ongoing in Los Angeles (Liraglutide), France (Lixisenatide, multi-site trial), and Oslo (Semaglutide). Another clinical trial is testing a pegylated version of exendin-4 called NLY01.
The abundance of trials demonstrates the great potential of this research area to deliver disease-modifying treatments that can considerably improve the quality of life for patients.
