It has been shown to function as a neuromodulator through the activation of purinergic receptors in astrocytes and displays protective properties by preventing the aggregation of amyloidogenic proteins—a key pathological event in neurodegenerative disorders such as Alzheimer’s disease (AD) and Parkinson’s disease (PD) [2]. This evidence concerns the gene P2RY1 and early-onset autosomal dominant Alzheimer disease.
