Direct Cell Conversion of Somatic Cells into Dopamine Neurons: Achievements and Perspectives.

In the last decade, direct reprogramming has emerged as a novel strategy to obtain mature and functional dopamine neurons from somatic cells. This approach could overcome issues linked to the use of human pluripotent stem cells such as ethical concerns and safety problems that can arise from the overgrowth of undifferentiated cells after transplantation. Several conversion methodologies have been developed to obtain induced DA neurons (iDANs) or induced DA neuron progenitors (iDPs).

Noncoding RNAs and Midbrain DA Neurons: Novel Molecular Mechanisms and Therapeutic Targets in Health and Disease.

Midbrain dopamine neurons have crucial functions in motor and emotional control and their degeneration leads to several neurological dysfunctions such as Parkinson's disease, addiction, depression, schizophrenia, and others. Despite advances in the understanding of specific altered proteins and coding genes, little is known about cumulative changes in the transcriptional landscape of noncoding genes in midbrain dopamine neurons. Noncoding RNAs-specifically microRNAs and long noncoding RNAs-are emerging as crucial post-transcriptional regulators of gene expression in the brain.
