The work has been published in the Journal of Neuroscience.

Focusing on the form of the disease found in early onset Alzheimer’s, in the 2 percent of patients who develop the progressive dementia before age 65, Tracy Young-Pearse said she and colleagues now “can examine amyloid beta secretion at the single-cell level, and better understand the responses of individual cells to drugs.”

“I think that could be very valuable” in developing treatments, she said.

Young-Pearse, an assistant professor at Harvard Medical School (HMS), said that her team’s latest work, carried out in collaboration with J. Christopher Love of the Koch Institute for Integrative Cancer Research at Massachusetts Institute of Technology, is an example of the latest advances in, and importance of, the ability to study disease processes on the level of individual cells.

“We didn’t have the ability to do this until recently,” Young-Pearse said. “The amount of heterogeneity between two cells that you think are the same can actually be huge. There are incredible differences between cell types. And we finally have the ability to look at those differences on the single cell level.

“Chris Love developed this great system for looking at individual immune system cells, such as B cells and T cells,” Young-Pearse said, and “he helped us apply his system to neuroscience. I’m really excited about being able to apply this to neurological disease.”

Both the miniaturization and scale of the research system are massive. A single slide has 86,000 wells in it, each of which can hold a single cell for analysis.
