How diabetes and obesity-related inflammation promote nervous system injury
Dr. Elzinga’s goal is to understand how immune system pathways respond to damage at the cellular level and promote injury of the nervous system. She is using multiple models to examine this injury and understand how it might promote cognitive impairment. These models are also increasing our understanding of how the different cell types in the nervous system interact. Already, they have begun to uncover the underlying mechanisms of injury and present possible treatment options for brain and cognitive impairment secondary to diabetes and obesity.

Dr. Elzinga News
New Insight Into Obesity’s Effect on Brain Health
Edith Briskin Emerging Scholar Sarah Elzinga, Ph.D., led a team that published findings in Frontiers in Cellular Neuroscience about an important pathway involved in cognition when placed on a high-fat diet.
New Study Links A High Fat Diet to Neurologic Disease
Michigan Medicine's Health Lab blog covered research led by Edith Briskin Emerging Scholar Sarah Elzinga, Ph.D., that support a specific immune pathway as a bridge between diet & neurologic disease. These findings were published in Frontiers in Immunology .
Altered Gene Expression Found in Obese Brains
Published in iScience , a team from the NeuroNetwork for Emerging Therapies used single-cell RNA sequencing to look at gene expression of microglia in the hippocampus that was inflamed due to obesity. These results further position microglia as a potential therapy target to preserve brain health when obesity is present.

Sarah Elzinga, PhD, Receives NIH Pathway to Independence Award
The Edith Briskin Emerging Scholar shares the research the award will fund—inflammation as a potential link between cognitive decline and metabolic dysfunction—and her experiences under the mentorship of Dr. Eva Feldman.
Announcing the Edith Briskin Emerging Scholar
Edith Briskin has established an emerging scholarship and introduced Sarah Elzinga, Ph.D., as the inaugural Edith Briskin Emerging Scholar at the NeuroNetwork for Emerging Therapies.
