In the present study, we show that human i PSCs can be successfully induced to differentiate into DARPP32-positive, GABAergic neurons which express the AR in a similar manner to striatal medium spiny neurons.
Expression of this receptor is affected by mutant HTT, and is gradually down-regulated at the transcriptional level during the progression of HD (22–24).
Nonetheless, the ability of the AR is required for the function of several neurotrophic factors, including brain-derived neurotrophic factor, fibroblast growth factor and glial cell line-derived neurotrophic factor (26–28).
MSNs are involved in the regulation of movement, emotion and cognitive ability (1,2), and thus HD patients gradually suffer from increased irritability and depression, involuntary movements (chorea), rigidity and eventually dementia.
Although the mutation which causes HD is known, our understanding of HD pathogenesis remains poor.
In genetic mouse models of HD, accumulating evidence indicates that stimulation of the AR agonist (CGS21680) can (i) significantly delay deterioration of motor coordination (23), (ii) increase proteasome activity and reduce the accumulation of mutant HTT aggregates (23,29) and (iii) attenuate NMDA-induced toxicity in corticostriatal slices of a transgenic mouse model of HD (R6/2) (30).
Accordingly, A gene, and induced their differentiation into GABAergic and DARPP-32-positive neurons.
Moreover, there is currently no effective strategy to delay the onset or slow down the progression of HD.
Various models have been developed to facilitate investigation into disease pathogenesis and to develop therapeutics.
Furthermore, we demonstrated that activation of the AR by selective agonists (CGS21680 and APEC) reduced oxidative stress-induced DNA damage and caspase 3 activation in the HD-i PSC-derived GABAergic neurons.
Our data imply that the human HD-i PSC model recapitulates, at least in part, the HD disease phenotype , and thus may be a potential platform for drug screening.
Adenosine is a well-characterized regulator of neuronal survival, which exerts its function through binding to specific cell surface adenosine receptors.Tags: Adult Dating, affair dating, sex dating
