Call-and-response circuit tells neurons when to grow synapses

LA JOLLA—Brain cells called astrocytes play a key role in helping neurons develop and function properly, but there’s still a lot scientists don’t understand about how astrocytes perform these important jobs. Now, a team of scientists led by Associate Professor Nicola Allen has found one way that neurons and astrocytes work together to form healthy connections called synapses. This insight into normal astrocyte function could help scientists better understand disorders linked to problems with neuronal development, including autism spectrum disorders. The study was published September 8, 2021, in the journal eLife.

The Kavli Foundation gifts Salk $3 million for cutting-edge neuroscience research

LA JOLLA—The Salk Institute announced today that The Kavli Foundation has committed $3 million to support ongoing neuroscience research at Salk as part of the joint UCSD-Salk Kavli Institute for Brain and Mind (KIBM). The gift—matched by an additional $3 million from Salk—will add $6 million to the KIBM Endowment, to enable faculty in neuroscience to work on the most impactful questions in the field. The Kavli Institute for Brain and Mind was established through a $15.5 million endowment commitment from The Kavli Foundation, shared between Salk and UC San Diego.

Nicola Allen receives $2.5 million Chan Zuckerberg Initiative early career award

LA JOLLA—Nicola Allen, an assistant professor in Salk’s Molecular Neurobiology Laboratory, has received a five-year, $2.5 million Ben Barres Early Career Acceleration Award from the Chan Zuckerberg Initiative (CZI), as part of a $51.95 million effort launching the CZI Neurodegeneration Challenge Network. This new network brings together experimental scientists from diverse research fields—neuroscience, cell biology, biochemistry, immunology and genomics—along with computational biologists and physicians, to understand the underlying causes of disorders such as Alzheimer’s, Parkinson’s, Huntington’s disease and ALS.

Salk awarded $19.2 million by the American Heart Association-Allen Initiative to study Alzheimer’s and aging in the brain

LA JOLLA—A team of Salk Institute researchers led by President Rusty Gage has been awarded $19.2 million over eight years by the American Heart Association-Allen Initiative in Brain Health and Cognitive Impairment to investigate mechanisms underlying Alzheimer’s disease and aging-related cognitive decline and uncover new therapies. This bold venture will comprehensively analyze interactions between five areas key to brain health: proteins, genes, metabolism, inflammation and epigenetics.

Brain cells called astrocytes have unexpected role in brain “plasticity”

LA JOLLA—When we’re born, our brains have a great deal of flexibility. Having this flexibility to grow and change gives the immature brain the ability to adapt to new experiences and organize its interconnecting web of neural circuits. As we age, this quality, called “plasticity,” lessens.

What happens when your brain’s support cells aren’t so supportive?

LA JOLLA—Potentially explaining why even healthy brains don’t function well with age, Salk researchers have discovered that genes that are switched on early in brain development to sever connections between neurons as the brain fine-tunes, are again activated in aging neuronal support cells called astrocytes. The work, which appeared in Cell Reports on January 2, 2018, suggests that astrocytes may be good therapeutic targets to prevent or reverse the effects of normal aging.
