Nicola J. Allen is a British neuroscientist.[1] Allen studies the role of astrocytes in brain development, homeostasis, and aging. Her work uncovered the critical roles these cells play in brain plasticity and disease.[2] Allen is currently an associate professor at the Salk Institute for Biological Studies and Hearst Foundation Development Chair.[1][3]

Education

[edit]

Allen conducted her undergraduate studies in Anatomical Sciences at the University of Manchester in England.[4] She completed her doctoral degree in Neuroscience at University College London in the United Kingdom in the lab of David Attwell.[5] She was a postdoctoral researcher in the lab of Ben Barres at Stanford University.[6]

Research

[edit]

Allen's research focuses on how astrocytes regulate synapses in the brain during disorders such as Alzheimer's disease.[5][7] In 2012 while she was a postdoc in the lab of Ben Barres, she showed that astrocytes secrete glypican 4 and 6, which is needed to create glutamatergic synapses between neurons.[6] She later expanded the research on glypican 4, showing that it is needed for the postsynaptic neurons to receive inputs.[7] Allen also showed that astrocytes excrete a protein called Chrdl1, which helps the maturation of the brain.[8][9] It also increased neuroplasticity in the brains of mice.[9]

Allen uses ribo-tagging, which is a molecular technique to determine which proteins are made by the ribosomes.[2] This technique allowed her to show that astrocytes make a protein that encourages the breakdown of connections between neurons.[2][10][11]
