Quantum dot conjugated saporin activates microglia and induces selective substantia nigra degeneration.

Landrigan J, Dwyer Z, Beauchamp S, Rodriguez R, Fortin T, Hayley S (2020) Quantum dot conjugated saporin activates microglia and induces selective substantia nigra degeneration. NeuroToxicology 76:153-161. doi: 10.1016/j.neuro.2019.11.007

Objective: To assess the impact of Quantum Dots (QDs) alone and QDs conjugated to Saporin, on substantia nigra microglia and dopamine neurons.

Summary: QDs might be a viable route for toxicant delivery and also have an added advantage of being fluorescently visible. Ultimately, we found SNc neurons to be exceptionally vulnerable to QD-saporin and suggest that this could be a novel targeted approach to model Parkinson’s Disease-like inflammatory pathology.

Usage: Biotin-labeled saporin chicken polyclonal was mixed with QDs coated with streptavidin. 2  μl of QDs (1 μM) were mixed with 2  μL of biotinylated saporin (56 μM) and 76  μL of phosphate buffer solution was added.
