The authors identified a missense mutation in the FTL gene (474G>A; A96T) in a 19-year-old man with parkinsonism, ataxia, corticospinal signs, mild nonprogressive cognitive deficit, and episodic psychosis. This mutation was also present in his asymptomatic mother and younger brother, who had abnormally low levels of ferritin in the serum. The patient and his mother displayed bilateral involvement of the pallidum.

The therapeutic use of enzyme inhibitors in treatment of neurodegenerative diseases has its origin in the anti Parkinson action of the selective monoamine oxidase (MAO) B inhibitor, l-deprenyl (selegiline ), a failed anti depressant in 1975. This led to further development of MAO- A and B, catechol-O-methyltansferase and cholinestrerase inhibitors as anti Parkinson and Alzheimer drugs. One of the main reasons for the cognitive deficit in dementia of the Alzheimer' type (AD) and in dementia with Lewy bodies (DLB) is degeneration of cholinergic cortical neurones and synaptic plasticity. This led to a correlation that similar to Parkinson's Disease (PD), cholinesterase inhibitors (ChEI) may also have therapeutic activity in AD. Significant percentage of AD and DLB subjects also nigrostriatal dopaminergic, locus ceruleous noradrenergic and raphe nucleus serotoninergic neurones. The present ChEI anti AD drugs have limited symptomatic activity and devoid of neuroprotective property that is needed for disease modifying action. It is becoming clear that there are no magic bullets for neurodegenerative disorders and shut gun approach is needed either as polypharmacology or drugs with multiple activity at different target sites in the CNS. The complex pathology of AD as well as cascade of events that leads to the neurodegenerative process has led us to develop several multifunctional neuroprotective drugs with several CNS targets with possible disease modifying activity. Employing the pharamcophore of our antiparkinson drug rasagiline (Azilect, Agilect, N-propagrgyl-1R-aminoindan) we have developed a novel multifunctional neuroprotective drug, ladostigil [TV-3326 (N-propargyl-3R-aminoindan-5yl)-ethyl methylcarbamate)], with both cholinesterase-butyrylesterase (Ch-BuE) and brain selective monoamine-oxidase (MAO) AB inhibitory activities possessing the neuroprotective-neurescue propargyl moiety, as potential treatment of AD and DLB and PD with dementias. Since brain MAO and iron increase in AD, PD and ageing, that could lead to iron dependent oxidative stress neurodegeneration, we have developed another series of multifunctional drugs (M30 HLA-20 series) which are brain permeable iron chelators- brain selective MAO inhibitors and possess the propargyl neuroprotective moiety. These series of drugs have the ability of regulating and processing APP (amyloid precursor protein) and reducing Abeta peptide, since APP is a metaloprotein, with an iron responsive element 5d'UTR similar to transferring and ferritin.

Iron plays a key role in secondary neuronal injury after intracerebral hemorrhage (ICH), and hepcidin is able to reduce brain iron in iron-overloaded rats by down-regulating iron transport proteins including ferroportin 1 and transferrin receptor 1. These led us to hypothesize that hepcidin might reduce iron-mediated neurotoxicity by inhibiting iron accumulation in ICH brain. Here, we examined effects of Ad-hepcidin (hepcidin expression adenovirus) on the nonheme iron contents, expression of hepcidin, ferritin and iron transport proteins, neuronal cell survival, water contents in the brain and/or cerebrospinal fluid (CSF), and ICH-induced apoptosis, neurological deficit by RT-PCR, Western blot analysis, NeuN Immunofluorescence, TUNEL, Fluoro-Jade B staining, behavioral performance and Morris water-maze tests in 510 rats. We demonstrated that hepcidin could significantly suppress the ICH-induced increase in iron and ferritin in brain tissues and CSF by inhibiting expression of iron transport proteins, increase neuronal survival by attenuating ICH-induced apoptosis, reactive oxygen species, neurodegeneration and brain edema, as well as effectively improve ICH-induced behavioral and cognitive deficit in rats. The findings collectively showed that hepcidin could effectively attenuate iron-mediated secondary neuronal injury after ICH in rats. This naturally existing protein can potentially be developed into a therapeutic drug for the treatment of ICH patients.
