TTUHSC Experts Receive Junior Investigator Research Grants through Texas Alzheimer’s Research and Care Consortium

More than 7 million Americans currently live with Alzheimer’s disease and approximately 13 million family members and friends provide unpaid care to loved ones with the disease, according to the Alzheimer’s Association.

Texas Tech University Health Sciences Center (TTUHSC) researchers Aric Logsdon, Ph.D., and Jonathan Singer, Ph.D., received Junior Investigator Research Grants from the Texas Alzheimer’s Research and Care Consortium (TARCC).

Logsdon, an assistant professor from the Department of Pharmacology and Neuroscience at TTUHSC School of Medicine, received a grant for the project, “Exploring Glycan Sulfation at the Blood-brain Barrier in Alzheimer’s Disease.” The award runs through Nov. 30, 2027, with total funding of $325,882.

Singer, an assistant professor for the TTUHSC Department of Pharmacology and Neuroscience and director of the Garrison Institute on Aging Memory Clinic, received a grant for his research, “Leveraging Technology to Meet the Needs of Rural Family Caregivers in Texas.” The grant provides $329,860 in funding through Nov. 30, 2027.

Created by the Texas Legislature in 1999, TARCC originally included TTUHSC, Baylor College of Medicine, UNT Health Fort Worth and The University of Texas Southwestern Medical Center. TARCC is a Texas-funded group of experts working together across the state to find a cure for Alzheimer's disease and improve everyday care for patients.

Lance R. McMahon, Ph.D., TTUHSC executive vice president for research and innovation, said that with Texas ranking third in the nation for Alzheimer’s cases, research such as this is critical to improving the lives of patients and families across the state.

“These awards support innovative early-career investigators who are advancing new approaches to better understand, treat and ultimately prevent Alzheimer’s disease and related dementias through collaboration and discovery.”

Logsdon’s lab studies the changes in the brain and blood vessels which may contribute to Alzheimer’s disease and other brain disorders. He examines how certain sugar-like molecules in the brain affect inflammation, brain health and communication between the brain and bloodstream. Using advanced laboratory techniques, he investigates how damage to the brain’s protective barrier and changes in these molecules may lead to memory loss and neurodegenerative disease. His work could help scientists develop new treatments and medications for Alzheimer’s and related neurological conditions.

Singer’s research specifically targets the unique healthcare challenges in West Texas.

He focuses on using technology such as telehealth and online tools to support families and caregivers in rural and Hispanic communities caring for loved ones with memory-related illnesses. Because many rural areas do not have easy access to specialists in aging and dementia care, these tools can bring education, emotional support and caregiving resources directly into people’s homes.

The goal is to help reduce stress and burnout among caregivers and caseworkers while also supporting their mental health and helping families cope with the emotional challenges that come with caring for someone with Alzheimer’s disease or dementia, Singer said.
