Ph.D. Candidate in Neurobiology
Yelena Grinberg graduated with a B.S. in Molecular and Cellular Biology and Psychology, with a minor in Chemistry in 2007 from the University of Illinois, Champaign-Urbana, under the mentorship of Dr. Donna Korol. In the Korol lab, Yelena studied neural plasticity with an emphasis on estradiol and memory. Following graduation, Yelena worked as a technician in Dr. Duncan Ferguson’s laboratory in the College of Veterinary Medicine at the University of Illinois, focusing on thyroid hormone physiology, pharmacology and toxicology. Yelena joined the Kraig laboratory in 2009, where she studies the role of insulin-like growth factor-1 (IGF-1) in neuronal activity-dependent neuroprotection. Specifically, Yelena’s in vitro work describing IGF-1-mediated reduction in brain susceptibility to spreading depression (the most likely cause of migraine aura and perhaps migraine) has lead to a thesis topic focusing on preclinical development of IGF-1 as a novel therapeutic for migraine. Work so far has shown that IGF-1 alters microglial response to spreading depression –decreasing microglial oxidative stress, TNF-alpha production, and promoting a ‘quiescent’ as opposed to an ‘activated’ morphology. Current work is translating these in vitro findings to the in vivo condition, where IGF-1 is being applied intranasally and spreading depression threshold evaluated in rat neocortex.
Yelena’s research interests also include 1) identifying the mechanisms by which aging results in decreased memory performance and neurovascular coupling, and 2) identifying mechanisms by which certain physiological interventions such as exercise, environmental enrichment, or introduction of plant-based dietary compounds improve cognitive function and alter neuroimmune signaling in the aged as well as the young.
