How B cells help the brain recover after stroke

B Cells Directly Alter Adaptive Plasticity to Support Functional Recovery After Stroke

NIH-funded research University of Kentucky · NIH-11137597

This work looks at whether a special group of B cells that make BDNF can help people regain thinking and movement after ischemic stroke, especially in older adults and women.

What this research studies

The project focuses on a subset of B cells that produce brain-derived neurotrophic factor (BDNF) and whether those cells support recovery of thinking and motor skills after ischemic stroke. Researchers use young and aged male and female mice to mimic post-stroke recovery and measure B cell responses, neuronal plasticity, motor function, and multiple types of cognition. Experiments will test if glutamate triggers B cells to increase BDNF and whether B cell-derived BDNF is required for recovery. A key aim is to determine if aged females have impaired B cell BDNF production that could explain higher rates of post-stroke dementia and depression.

Who could benefit from this research

Good fit: This research would be most relevant to adults who have had an ischemic stroke and are at risk for post-stroke cognitive decline or motor impairment, especially older adults and women.

Not a fit: People without ischemic stroke or those whose recovery is driven by unrelated mechanisms, or patients outside the biological window for immune-driven repair, may not benefit from these findings.

Why it matters

Potential benefit: If successful, this could point to therapies that boost B cell-derived BDNF to improve motor recovery and lower the chance of post-stroke cognitive decline, particularly in older women.

How similar studies have performed: Some prior animal work shows immune cells can aid brain repair, but directly linking B cell-derived BDNF to preventing post-stroke cognitive decline is largely novel.
