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

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

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]}
