Catalog

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.

Protocol

Unconventional secretion of alpha-synucein mediated by palmitoylated DNAJC5 oligomers

This protocol, carried out according to the manufacturer’s instructions, uses a classical ELISA experimental design with sensitive electrochemical detection to provide a measure of 𝜶-synuclein concentration in the conditioned media of cultured iPSC-derived human cells.

Protocol

Differentiation of human medium spiny neurons (MSNs) from induced pluripotent stem cells (iPSCs)

This protocol generates human medium spiny neurons (MSNs) from induced human pluripotent stem cells (iPSCs).

Dataset

Datasets and key resources used in Do, Quyen B. et al. (2023) – 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 modelling 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.

Protocol

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.

Article

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.

Article

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.
