ASAP is committed to accelerating the pace of discovery and informing a path to a cure for Parkinson’s disease through collaboration, research-enabling resources, and data sharing. We’ve created this catalog to showcase the research outputs and tools developed by ASAP-funded programs.


Differentiation of SH-SY5Y cells

This protocol describes a standard procedure to differentiate SH-SY5Y cells into dopaminergic neurons using retinoic acid.


Differentiation of human cortical neurons (CNs) from induced pluripotent stem cells (iPSCs) and their coculture with rat astrocytes

This protocol described the production of human cortical neurons from induced pluripotent stem cells in cocultured with commercially available rat astrocytes.


Early striatal hyperexcitability in an in vitro human striatal microcircuit model carrying the Parkinson’s GBA-N370S mutation

The results highlight the unique utility of modeling striatal neurons in a modular and highly physiological circuit, which is essential to reveal mechanistic insights of the loss of electrical functional integrity in the striata of GBA1 PD patients.

Inhibition of striatal dopamine release by the L-type calcium channel inhibitor isradipine co-varies with risk factors for Parkinson’s

Published: This data show that LTCC function in DA axons, and isradipine effect, are locally governed and suggest they vary in a manner that in turn might impact on, or reflect, the cellular stress that leads to parkinsonian degeneration. View original preprint.

Sst+ GPi output neurons provide direct feedback to key nodes of the basal ganglia and drive behavioral flexibility

Preprint: The GPi-LHb pathway is the main output of the basal ganglia suggested to shape motivated behaviors. Here, the authors propose that GPi Sst+ neurons drive behavioral flexibility through a direct feedback signal to balance the activity of key nodes in the basal ganglia.
