Parkinson's Disease

With approximately 7 million people suffering from Parkinson’s disease (PD) world-wide, PD is one of the most frequent age-related diseases of the central nervous system. It is caused by the death of neurons in a part of the brain that controls movement. This damage results in the typical motoric symptoms, such as shaking, rigidity or slowness of movement. Other symptoms include sleep disturbance, depression and dementia. The cognitive decline is one of the most disabling symptoms of PD. This type of dementia is called PD dementia (PDD).

PD research at BPRC is focused on understanding the processes that contributes to the pathology and clinical expression of the disease. Our models are used for the development of pharmaceutical and non-pharmaceutical therapies that stop the neurodegenerative process, suppress disease symptoms and prevent side effects of the current medications.


Compensation by the Red Nucleus may explain why primates can develop stable Parkinson’s disease



BPRC identified a new target to manage Parkinsonian symptoms. This approach focuses on a part of the brain called the “red nucleus”. This red nucleus controls movement in quadrupedal animals (animals that walk on four legs, like rodents and cats), and it also regulates the crawling movement in babies until other areas of the brain then take over. It is known that the red nucleus in PD is enlarged compared to non-PD people. Presumably because the red nucleus gets activated to compensate for affected parts of the brain.

Our researchers examined whether the same phenomenon could be observed in monkey models of PD. Their findings showed that animals with a larger red nucleus displayed fewer Parkinson’s symptoms than animals with a smaller red nucleus. In addition, stimulation of this compensatory pathway seemed to increase the size of the red nucleus even more. The study also focused on a part of the red nucleus that mainly occurs in humans and primates. Though a different part of the red nucleus is active in quadrupeds, it is striking to note that these animals can spontaneously recover from PD symptoms, whereas this is not observed in primates. This is yet another indication that the red nucleus may be very important. Read more >
