Postdoctoral Associate Awarded Prestigious Grant

Ravikanth Velagapudi, PhDThe Network for Investigation of Delirium Unifying Scientists (NIDUS) has awarded Duke Anesthesiology’s Ravikanth Velagapudi, PhD, a 2019-2020 NIDUS Junior Investigator Pilot Award (12-month, $80,500 grant) for his proposal titled, “Profiling Postoperative Neuroinflammation in a Mouse Model of Delirium Superimposed on Parkinson’s Disease.”

Velagapudi’s proposal was selected through a rigorous review process from a pool of highly-competitive applications. His project will help gain fundamental knowledge on the impact of surgery on preclinical Parkinson’s disease (PD) models. Currently, millions of Americans live with PD and routinely undergo common surgical procedures, such as orthopedic surgery. Although lifesaving, surgery can increase the risk for cognitive complications like delirium, which in many cases associate with worse prognosis, increased health care costs, and even death. This is especially concerning in frail subjects and older adults who already suffer from ongoing neurodegeneration, such as Alzheimer’s disease, but also PD. This specific project will explore the effects of surgery-induced postoperative neuroinflammation in a genetic PD mouse model. Results from these experiments will provide novel understanding on how surgical trauma synergizes with PD pathology and may lead to novel therapeutic targets to treat delirium in subjects with ongoing PD pathology.

“It is a great opportunity to receive this pilot award from NIDUS under the junior investigator track to study delirium in PD,” says Velagapudi. “To date, this is a largely understudied subject, especially in the context of preclinical models and signaling mechanisms. In fact, few studies so far have addressed the effects of delirium on PD.” This pilot grant also provides a unique and timely opportunity to build a future career development research program for Velagapudi focusing on the interactions between postoperative delirium and PD-neurodegeneration.

Velagapudi is a postdoctoral associate in the Neuroinflammation and Cognitive Outcomes Laboratory in Duke Anesthesiology, led by Dr. Niccolò Terrando, who says this prestigious award is a remarkable accomplishment for his mentee. “I am very proud of Ravi’s achievement in just one year with my team. This award will provide an exceptional training opportunity and will further grow our collaboration with Dr. Laurie Sanders’ group in Duke Neurology, who are experts in PD pathogenesis.”

Velagapudi will present the findings of his project at the annual American Delirium Society meeting in 2021.
