A recent Cell Reports study found that different forms of amyloid-β42 (Aβ42) can trigger distinct toxic effects in neurons and microglia—offering new insight into how amyloid pathology may contribute to Alzheimer’s disease.

The researchers used AAT Bioquest’s Cal-520® AM calcium indicator to study changes in calcium signaling associated with Aβ42 toxicity.

Congratulations to the authors on this important work, and thank you for trusting AAT Bioquest products to support your research. 🧠🔬
