flag Scientists found 100 Alzheimer’s risk genes affect brain health in fruit flies, revealing key pathways linked to the disease.

flag Scientists used fruit flies to study 100 human Alzheimer’s risk genes, finding many are active in adult brains and crucial for neuron function, stress response, and resilience to toxic proteins. flag Turning off 18 genes caused neurodegeneration, while 35 were vital for normal neuron activity and eight for stress recovery. flag Twenty-eight genes influenced responses to amyloid-beta and tau. flag The research, led by Baylor College of Medicine and Texas Children’s Hospital, reveals diverse biological pathways may underlie Alzheimer’s, explaining symptom and treatment variability. flag Findings are shared via ALICE, a public data portal.
