NIH-funded research University of South Dakota · NIH-11127435

What this research studies

Researchers are testing engineered versions of erythropoietin (EPO) that retain neurotrophic effects without increasing red blood cell production. They focus on the hippocampus, a brain region important for learning and memory, and examine how these compounds change cellular signaling, brain circuits, and behaviors linked to attention and memory. The work uses laboratory experiments and preclinical models and is informed by prior human studies of EPO's cognitive effects. The aim is to identify compounds that improve cognition while avoiding blood-related risks like increased viscosity or clotting.

Who could benefit from this research

Good fit: People with cognitive impairment or memory/attention problems related to neuropsychiatric conditions could be the most relevant candidates for related future trials or sample donation.

Not a fit: People without cognitive symptoms, or those who cannot receive experimental biologic treatments or have active clotting disorders, may not benefit from this line of research.

Why it matters

Potential benefit: If successful, this work could lead to therapies that improve memory and thinking in people with cognitive deficits while reducing the vascular risks tied to regular EPO.

How similar studies have performed: Prior human studies found that native EPO can improve cognition, but the non-erythropoietic EPO-like compounds studied here are newer and have been mostly tested in preclinical work so far.
