abstract = {Parkinson's disease (PD) is the most common movement
disorder and the second most common neurodegenerative
disease after Alzheimer's disease, affecting an increasing
number of patients due to the demographic trend towards an
aged population. Oxidative stress, mitochondrial dysfunction
and protein aggregation are pathophysiological alterations
consistently found in the course of the disease, however,
the etiology of sporadic PD still remains enigmatic. Thus,
the identification of genes which are reponsible for
familial variants was a major breakthrough. Importantly,
several PD-linked gene products have a direct or indirect
impact on mitochondrial integrity, emphasizing a crucial
role of mitochondria in the pathogenesis of PD.
Loss-of-function mutations in the E3 ubiquitin ligase parkin
or the mitochondrial kinase PINK1 are associated with
autosomal recessive parkinsonism. Our previous work revealed
that parkin is a stress-responsive protein with a remarkably
wide neuroprotective capacity, preventing cell death under
various stress conditions. An early consequence of parkin or
PINK1 silencing in human cells is a decrease in
mitochondrial membrane potential and ATP production and
increase in mitochondrial fragmentation. Remarkably, parkin
can increase the clearance of dysfunctional mitochondria by
mitophagy in a PINK1-dependent manner. We will discuss the
underlying mechanisms and present data indicative of a
regulatory crosstalk between the autophagic machinery and
mitochondrial dynamics.},
