flag A Texas Tech study finds the blood-brain barrier remains mostly intact in Alzheimer’s mice with amyloid plaques, challenging previous assumptions.

flag A Texas Tech University study challenges the idea that the blood-brain barrier leaks in Alzheimer’s, finding it largely intact in Tg2576 mice with amyloid plaques. flag Using advanced tracking methods, researchers detected minimal tracer entry into the brain, suggesting barrier function remains stable despite plaque buildup. flag The findings question assumptions about drug delivery in Alzheimer’s and highlight the need for better models and further research, including testing FDA-approved antibodies for potential BBB effects.
