In this study we present the use of elastic macroporous cryogels for differentiation and transplantation mature neurons. We develop a coating suitable long-term neuronal culture, including stem cell differentiation, by covalent immobilization neural adhesion proteins. context therapy Parkinson's disease, show compatibility with established dopaminergic both immortalized mesencephalic progenitor...

Ibuprofen, a non-steroidal anti-inflammatory drug (NSAID), showed very promisingneuroprotection action, but it suffers from high first pass metabolism and limited abilityto cross blood brain barrier. Severe gastric toxicity following oral administration furtherlimits its utility. Hence, the aim of this study was to investigate whether ibuprofen loadedmucoadhesive microemulsion (MMEI) could enha...

Primary cultures of nigral tissue are widely used as a model system to assay effects of trophic and toxic agents on dopaminergic neurons. Cultured dopaminergic neurons have been successfully transplanted in animals and led to behavioral improvement in animal models of Parkinson’s disease. The success of these preclinical studies has encouraged investigators to begin clinical trials using transp...

Reduction of mitochondrial complex I activity is one of the major hypotheses for dopaminergic neuron death in Parkinson's disease. However, reduction of complex I activity in all cells or selectively in dopaminergic neurons via conditional deletion of the Ndufs4 gene, a subunit of the mitochondrial complex I, does not cause dopaminergic neuron death or motor impairment. Here, we investigated th...

objective(s): the main characteristic of mesenchymal stem cells (mscs) is their ability to produce other cell types. electromagnetic field (emf) stimulates differentiation of mscs into other cells. in this study, we investigated whether emf can effect on the differentiation of mscs into dopaminergic (da) neurons. materials and methods: an emf with a frequency of 50 hz and two intensities of 40 ...

Dopaminergic midbrain neurons are involved in many important brain functions including motor control, as well as emotive and cognitive tasks. They also play critical roles in major disorders likes Parkinson disease, schizophrenia, drug abuse and attention-deficit hyperactivity disorder. This bewildering diversity of distinct dopaminergic functions appears to be in contrast to the routinely assu...

Parkinson disease (PD) is the second most common neurodegenerative disease, characterized by denervation of dopaminergic neurons in substantia nigra. Its cardinal symptoms are rigidity, tremor, and bradykinesia. The gold-standard treatment for PD administration levodopa, but no approved can stop progression PD. Thus, development new therapeutics based on pathogenesis needed. In this study, we r...

Midbrain dopaminergic neurons are essential for appropriate voluntary movement, as epitomized by the cardinal motor impairments arising in Parkinson's disease. Understanding the basis of such motor control requires understanding how the firing of different types of dopaminergic neuron relates to movement and how this activity is deciphered in target structures such as the striatum. By recording...

Cell-gene therapy is a dynamic constituent of novel medical biotechnology. Neurodegenerative disordersin which damage to or demise of specific brain cell types plays central role, are clear examples of diseasecandidate for cell replacement therapy. Dopaminergic (DAergic) neurons biosynthesize dopamine, a vitalneurotransmitter in the central nervous system. Due to the involveme...

Parkinson's disease (PD) results primarily from the death of dopaminergic neurons in the substantia nigra. Current PD medications treat symptoms; none halt or retard dopaminergic neuron degeneration. The main obstacle to developing neuroprotective therapies is a limited understanding of the key molecular events that provoke neurodegeneration. The discovery of PD genes has led to the hypothesis ...
