Disease - Disease Buddy

A featured graphic with a white background titled 'A Potential New Trigger for Alzheimer's Disease'. It features two main boxes comparing cell transport side-by-side. The left box, 'Healthy Brain Cell Transport,' depicts tau proteins successfully stabilizing tracks so nutrients and materials move freely. The right box, 'Disrupted & Tangled,' shows amyloid beta displacing tau, causing cell transport to break down and tau proteins to clump into a chaotic purple web labeled 'Tau tangles'. A summary line at the bottom reads, 'A focus on cell transport as a key driver of disease'.
