Imaging (IMAGE) Lancaster University Caption Scientists used a special imaging technique to observe how Tau protein clumps in the brain tissue of genetically modified flies in response to treatment with RI-AG03. Without the treatment (A), they saw toxic clumps of Tau fibrils (arrow) and oligomers (arrowhead). After treatment (B), those harmful clumps disappeared, and only large round structures remained, which the scientists believe are less harmful.
