Scientists at Johns Hopkins Medicine grew tiny brain models from people with Alzheimer's. These mini-brains helped them predict how different patients might respond to certain medications.
Scientists at Johns Hopkins Medicine have made a new discovery that could help treat Alzheimer's disease. They created small clusters of brain tissue in the lab, called organoids, using cells from people with Alzheimer's. These tiny brains were grown from blood samples collected from patients with Alzheimer's.
The researchers wanted to know if these mini-brains could show which medications might work best for each patient. They used a medication called escitalopram oxalate, which is often prescribed to help manage symptoms of Alzheimer's. The team found that the organoids released tiny particles called extracellular vesicles that carried information about the disease.
The study included hundreds of mini-brains, representing individual patients with Alzheimer's and healthy individuals. This was one of the largest studies of its kind. The researchers discovered that the patient-derived organoids showed distinct molecular changes compared to those grown from healthy individuals. These changes were related to communication between brain cells, inflammation, and pathways associated with Alzheimer's.
The team treated some of the mini-brains with escitalopram oxalate and found that it increased proteins involved in serotonin signaling and communication between brain cells. This suggests that these tiny brains can help predict how patients might respond to certain medications.
Why It Matters
This discovery could lead to more personalized treatment for Alzheimer's patients. It may also help doctors choose the best medication for each patient, which could improve their quality of life.
