About Parkinson's Disease

Parkinson’s disease (PD) is the second most frequent neurodegenerative disease after Alzheimer’s disease. PD is caused by the degeneration of dopaminergic neurons of the substantia nigra and their nerve endings. It causes kinetic dysfunctions, such as limb tremors, but also non-motor symptoms. Approved treatments against PD are symptomatic and only partially relieve the kinetic issues. To date, there is no medication available that treats or delays the progressive neurodegeneration of the disease. Therefore, there is a great need for the development of therapies and treatments that will directly target the pathogenesis of the disease, will actually be neuroprotective and will delay the progression of the disease.

The Project

The deposition of protein inclusions in the brain, as a result of protein misfolding and aggregation is a common feature of various neurodegenerative diseases, such as Alzheimer’s disease. The same phenomenon is also observed in PD, characterized by the accumulation of aggregated forms of the presynaptic protein α-synuclein (aSyn) in the brain. Studies have shown that aggregated forms of aSyn are particularly toxic to neuronal cells.

Research Objectives

Specific aim 1

Biosynthesis of combinatorial libraries of cyclic oligopeptides and their functional screening for the discovery of inhibitors of aSyn aggregation.

Specific aim 2

Construction of a library of extracts and isolated natural products derived from marine organisms and detection of the bioactive molecules that inhibit the aggregation of αSyn.

Specific aim 3

In vitro evaluation of the selected compounds for their ability to inhibit the formation of neurotoxic aggregates of aSyn in neuronal cells cultures.

Specific aim 4

Pharmacokinetic and toxicological evaluation of the selected αSyn aggregation inhibitors.

Specific aim 5

In vivo evaluation of the ability of the selected molecules to inhibit the generation and dispersion of aSyn neurotoxic aggregates in a mouse model.

Specific aim 6

Preparation for the development of a nutritional supplement that promotes kinetic and mental function of older people as well as lead compounds with potential therapeutic properties against PD.
